Introduction

A total of 109 elements have been discovered and incorporated into the periodic table. Many of these elements are found in the earth’s mantle, crust, and soil, though their abundance varies. The chemical makeup of plants is, to some degree, influenced by the composition of the soil. However, since plants are active organisms, they exhibit selectivity in absorbing elements from the soil. Plants accumulate elements at different rates, absorbing some in large quantities, others in smaller amounts, and excluding most altogether. Before proceeding, it is important to familiarise with several key terms frequently used in this chapter.

Nutrient: A nutrient element is essential for an organism to complete its life cycle, and a deficiency in this element leads to specific deficiency symptoms. The negative effects can only be corrected by providing that particular element. Nutrient elements essential for plants may not be necessary for other organisms, and vice versa. Depending on availability, the nutrient levels in a plant can be deficient, sufficient, or toxic. A nutrient is considered deficient when its concentration is so low that it significantly limits growth and causes recognisable deficiency symptoms. If nutrient levels cause reduced growth without visible deficiency symptoms, they are termed insufficient. The nutrient content range in plants that supports optimal yield of crops is considered sufficient. When the concentration of a nutrient becomes high enough to significantly reduce growth, it is considered toxic.

The active management of soil nutrients to ensure optimal plant nutrition has been a fundamental practice in agriculture since its inception. For centuries, production of agriculture depended on the organic materials recycling like manure and crop residues. Interest in plant nutrition dates back to ancient times, first captivating philosophers and later becoming a subject of rigorous scientific inquiry. The history of how plants obtain nutrients is marked by numerous misconceptions and incorrect theories. Exploring the long-standing efforts to uncover this essential agricultural process highlights the perseverance and brilliance of early thinkers and scientists. It also underscores that modern understanding, which may now seem straightforward, is the culmination of significant scientific endeavour. The concept of managing fertility of soil to boost yield of crops is far from new—its origins are intertwined with the earliest practices of agriculture. Ancient civilizations recognized the value of applying organic matter such as green manure, farmyard manure, night soil, bone, and wood ashes to enhance soil productivity.

Millets are the staple food cropsacross the globe. The ability to thrive in harsh conditions established them as most suitable for current climate adversaries. The nutritional richness of millet reminded the need for adding them to our food basket.Despite possessing several desirable traits their cultivation is limited to a few pockets across the globe.Though significant progress has been achieved by conventional and transgenic breeding programs inmillets, there is a need for rapid improvement to meet the current needs.In order to accelerate the pace of breeding efforts, several molecular biology and biotechnology tools are being deployed by plant breeders. In the meantime, genome editing techniques like CRISPR, TALENS, ZFNs, Base and Prime editing have revolutionized the methods of genome engineering among which CRISPR has emerged as the most rapid, convenient and effective mechanism. The availability ofwhole genome sequence information, identified candidate genesfor various traits and successful transformation methods of millets promoted the application of CRISPR and resulted in the improvement of several traits. Initially, its application has been limited due to the restricted policies across the globe but the gradual change in the policies promoted genome editing across several parts of the globe. Thus, the application of genome editing for millet crop improvement can bring back those ancient grains to our food basket.

Agriculture is the support for the sustainable health and economic growth of the country. With the frequent changes in climatic conditions and increase of global population, it is important to come up with new varieties and nutrient rich crops. In this context, underutilized and neglected millets, considered as “nutri-cereals” or “smart foods” due to better adaptation in diverse environmental stresses and tolerance to insect pests and diseases, also a staple crop for hunger-stricken areas. Millet production is limited by the lack of intensive farming and deployment of genetic tools for trait and nutrition improvement. The recent advancement in machine learning (ML) and Artificial Intelligence (AI) technologies are key to depict plant response to environmental perturbation in huge data sets. Therefore, precision agriculture or smart farming is necessary to explore the genetic makeup of the neglected millets. AI has a substantial potential to handle numerous challenges in the formation of knowledge-based farming systems. The next agricultural revolution would emphasize more on farm machinery using AI integrated with the Internet of Things (IoT). In Smart agriculture, deep learning facilitates fast and interesting data analysis and provides support to researchers and farmers by the outcomes generated from the analysis. Here, we emphasize on the advancement of AI and its application to monitor the underutilized and neglected millets quality, yield and disease assessment. This chapter summarizes how AI can contribute to the improvement of sustainable productivity and quality of underutilized and neglected millet.

The demand of day by day increasing population there is lacking of nutritious food to peoples all around world. Underutilized crops like small or minor millets are having more nutrition and providing calories up to 2000 to 3000 calories per person per day than our staple crops i.e wheat, rice, and maize etc. Small Millets are the most underutilized crop in the world possessing high nutrient-cereal qualities and potential for the improvement of food security, nation income and generate the employment for the rural peoples. Millets are rich in nutrients such as proteins, fibers, carbohydrates, fats, vitamin-B, and minerals like calcium, phosphorus, magnesium, iron, potassium, and zinc etc.They are highly nutritive crop, non-acid forming, glutan free and help in reducing blood sugar level, blood pressure, diabetes and cardiovascular diseases. They also help in preventing asthma and migraines sufferings and fighting malnutrition in children s and adults.S mall millets are considered the forgotten crop species because of lower yield compared to other millets i.e. Sorghum and Pearl millet and cereals i.e. rice, wheat, maize etc. Being a highly nutritive cereal crop, easy to digest, high fibers and low glycine-max content, environment friendly and prevent the human hazards small millets still remained neglected and underutilized crop. Out of 200 underutilized crops identified 29 are small millets species (NAS USA, ICUC). Considering the food demand of common peoples, emerging health consciousness and nutrient demand for food security emerged small millets to limelight because of ecologically sound to climate. Still, the harvest of crop demands combination of computational technologies to full-fill food needs of population. Recognizing the potential of small millets in improving the national income UN-FAO announced the year 2023 as International Year of Millets. This chapter focused on application of climate smart agricultural methods such as artificial intelligence for the improvement of small millets to achieve future food security.

Millets have potential as both food and fodders crops. Foods made from millet are abundant in micronutrients and necessary amino acids for regulatory functions. Since, millets were traditionally grown under adverse conditions, a great amount of polymorphism was preserved, making millet crops naturally resistant to abiotic and biotic stresses. Using data-driven technology to increase genetic gain in breeding operations can improve traditional breeding. Artificial intelligence can be used to create varieties that are adapted to certain soil and climatic conditions. In order to achieve breeding goals, machine learning (ML) is crucial in data mining and analysis, providing information for decision-making. We have been able to generate information on interesting genes using data mining and allele identification methods. For the exploitation of the natural variation and the identification of target genes, advances in high-throughput sequencing for the detection of genetic variations as well as the role of phenomics in genomics-assisted breeding can be employed. QTLs and marker-trait correlations can be identified via genome-wide association analyses. Multiple loci and genes that control agronomic traits have can be studied by comparative and functional genomics. Model selection is crucial for ML algorithms in smart breeding, which depends on knowledge in genotype, phenotype, and G×E interaction to be handled through computer science.

Millets are an essential food in the world’s semi-arid and arid regions. These are effective energy providers. They provide dietary fibre, polyphenols, fatty acids, minerals, vitamins and protein. The production of tropical crops is highly risky due to the pest outbreaks and increased abiotic pressures triggered by the climate change. Despite the fact that conventional breeding methods have greatly enhanced crop yield and output, new strategies are needed to further enhance crop productivity in order to fulfil the world’s expanding need for the food. The use of site-specific nucleases like zinc finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN) and clustered regularly interspaced short palindromic repeat associated proteins 9 (CRISPR-Cas9) are the genome editing technologies developing very fast. The advancement of plant genome research and its use in plant breeding are significantly aided by such achievements. CRISPR/Cas9 and related genome editing methods are emerging as appropriate methods to reduce the negative consequences of climate change and assure the long-term food security of tropical countries’ growing populations.

Millets categorized as cereal crops are rich sources of nutrients, mostly cultivated across arid and semiarid areas of the world, specifically in southeast Asia and Africa. Millets are easy to cultivate, demands minimal field input and have appreciable market values. Despite of great value of millets, their production is limited mainly because of climate change which triggers multiple abiotic stresses like drought, high temperature, salinity, etc. Even though millets can withstand the majority of abiotic stresses, it necessitates their further improvement to develop more resilience against unprecedented effects of climate change by incorporating or enhancing stress tolerance characteristics. It is currently not attainable to create stress tolerant and high yielding varieties through conventional breeding techniques and thus modern approaches like genome editing become inevitable to achieve this goal. Also, available data for genome sequences of millets in these years promotes genome editing. The technique has drawn tremendous attention recently due to its potential in precise modification of alleles and is considerable to speed-up crop breeding by targeting important traits with precision. Additionally, many stress-resistant genes are identified in related monocots and are reported to be orthologs of millets which could assist genome editing for developing stress resilience and productivity in millets. Above all, the technique has also gained legal acceptance and has potential to revolutionary counter climatic challenges.

Due to their remarkable health benefits, such as their low glycemic index, rich amino acid profiles, and abundance of B vitamins and antioxidants, little millets, formerly hailed as nutri-cereals, are once again becoming important dietary staples. These crops, which include a variety of species like finger millet, foxtail millet, and barnyard millet, have stimulated innovation in the food business by producing value-added goods like rice analogs, noodles, and biscuits. Additionally, their medicinal qualities could help advance research on nutraceuticals. Small millets are essential to climate-smart agriculture because of their renowned resilience, which allows them to flourish on marginal soils and in difficult climates. Breeding efforts seeking to create climate-resilient, high-yielding, and lucrative cultivars can benefit greatly from their extensive genetic diversity, which is conserved in traditional landraces and farmer-managed cultivars. Even with their potential, small millets’ genetic development projects are still in their early stages, requiring concentrated efforts to find trait-specific donors and enhance breeding techniques. In addition to preserving their ethnobotanical and cultural heritage, the conservation of their genetic resources supports international initiatives for environmental sustainability and food security. Small millets have the potential to become a vital component of sustainable and nutritionally enhanced agricultural systems by incorporating cutting edge agricultural techniques and speeding up breeding improvements.

Introduction

Millets, which are small-seeded grasses belonging to the Poaceae family, have a rich historical and cultural significance as they have been cultivated for thousands of years (Goron and Raizada, 2015; Wen et al., 2014; Cheng, 2018). They remain an important crop in various regions worldwide, particularly in developing countries where they serve as a staple food for millions, especially in rural areas. Millets offer several advantages as they are gluten free and provide valuable protein, fiber, and minerals, making them highly nutritious for both human consumption and animal feed. The diverse range of millets includes pearl millet (Cenchrus americanus (L.) Morrone), foxtail millet (Setaria italica (L.) P.Beauv.), proso millet (Panicum dichotomiflorum Michx.; syn. Panicum miliaceum Walter), finger millet (Eleusine coracana (L.) Gaertn.), barnyard millet (Echinochloa frumentacea Link), kodo millet (Paspalum scrobiculatum L.), little millet (Panicum sumatrense Roth), and more (Ahmad et al., 2018; Bora et al., 2019). These grains have a significant historical presence globally, with evidence of cultivation in ancient China, Greece, and Rome (Li et al., 2020a; Huan et al., 2022). In India, millets have maintained their importance as a vital crop for thousands of years and continue to be an integral part of the diet in many regions of the country today (Padulosi et al., 2015; Li et al., 2020b).

Millets are highly nutritious and play a significant role in many people’s diets around the world. They have traditionally been transformed into a range of products through fermentation and malting for centuries. In the era of sustainable development, we still lag in using millets as a primary source of nutrition even after knowing that they are rich in terms of nutrition and other essential elements as compared to cereals. Today we have lots of information regarding different millets; nutrition content, methods of preservation, fermentation, malting, its products etc. Foods made from millet are regarded as potential prebiotics because they can improve the availability or functionality of probiotics, which has major positive effects on health. Foods have been fermented in order to enhance their flavor, texture and palatability. Although fermentation can result in a variety of products, the most prevalent ones are ethanol, lactic acid, carbon dioxide and hydrogen gas (H2 ). Commercial applications for these materials include use in food, vitamins, medications and industrial chemicals. Additionally, fermentation increases the amount of protein present, improves the accessibility of carbohydrates and reduces antinutritional components like tannin and phytic acid. Even though it has some drawbacks, such as the potential for contamination with dangerous microbes, fermentation technology is proven to enhance the nutritional quality of food products. This chapter covers the millet fermentation technology’s effects on the nutritional composition of the millets, contemporary developments in fermented millet-based products and technological improvements examined in the millet fermentation technology.

Millions of people worldwide suffer from food insecurity and malnutrition, which are exacerbated by issues including pollution, overcrowding, climate change, and economic hardship. These problems highlight the necessity of changing food systems for better immunity and health since they lead to both undernutrition and overnutrition. Essential carbs, fiber, fats, and important micronutrients including iron, calcium, potassium, zinc, and magnesium are all found in nutrient-dense grains such as foxtail, kodo, proso, tiny, and pearl millets. These millets are widely accessible and have several health advantages. For example, pearl millet is high in amylose starch and contains essential minerals like phosphorus and magnesium, whereas proso millet is a good source of iron, calcium, potassium, and B-vitamins. B vitamins, iron, calcium, and zinc are all found in kodo millet, while finger millet is a great provider of calcium, iron and magnesium. The nutritional profile of millets is further improved by processing methods like milling, germination, extrusion, and fermentation. Prominent research organizations, including as ICRISAT, ICAR, and CGIAR, are actively working to conserve millet and create better types to combat chronic illnesses and malnutrition. Targeted improvements in disease resistance and nutrient content are now possible because to biotechnology advancements. For improved worldwide health outcomes, dietary patterns must nonetheless be changed and these nutrient rich grains incorporated into contemporary food systems, notwithstanding current advancements.

Minor millets, that belong to members of the cereal grass family, are advantageous in areas where large crops like Bread wheat, Rice paddy, and maize are relatively ineffective because they have a wide range of genetic diversity and thrive in marginal environments. The varied soil types, temperatures, heat and light cycles, and rainfall patterns across India all support the cultivation of minor millets. Finger millet, barnyard millet, foxtail millet, proso millet, and many more types of minor millet are used in agriculture. The majority of those who depend on these millets for sustenance and income are small-scale indigenous farmers and dwellers of rainfed areas, mainly among impoverished tribal populations numbering in the millions. Coarse cereals,now a days known as Nutri cereals or nutraceutical flora and are no longer known as coarse cereals as a potential global answer to malnutrition and unrecognized hunger. Minor millets have long been an essential component of Indian tribal societies’ agricultural systems and practices. They have used little millets for both famine prevention and ethnomedicine since the beginning of time. This chapter focuses on how little millet could help people have access to food and nutrition security while reducing hunger and malnutrition.

Millets which are also known as “Shree Anna” are a type of grass with small seeds that belongs to the Poaceae family and are widely grown throughout the world. Millets have high levels of proteins, minerals, vitamins, and antioxidants that why they are known to be climate-change-resilient crops. Proteins are essential amino acids that the body cannot synthesize and are used as a nitrogen source during embryo development following germination. Millets are high in dietary fibre and are important staple crop in many parts of the world. They are versatile grains that can be used to make a variety of food products, including millet flour. Millets are good for cardiac health, weight management, antioxidant activity, and may have anti-cancerous properties. They are nutrient- dense, provide sustained energy, and contain antioxidants such as polyphenols and flavonoids. Millets are considered safe and have a variety of health benefits. Surprisingly, millets perform major non-millet cereals in terms of nutrition. They are particularly high in dietary fibres, minerals, antioxidants, phytochemicals, and polyphenols, all of which have broad-spectrum positive effects on human health.

Millets are a type of minor cereals found in the Poaceae family. Millets are often described as “Nutri-Cereals” since they contain more nutrients than commonly produced main cereals. They are an important part of human’s diet in the world. These are foods with a high nutritional content, gluten-free and have nutraceutical qualities. The adequate amount of protein (essential amino acid), micronutrients and phytochemicals are found in millets. The phytochemicals found in millet grains enhance human health by lowering cholesterol and phytates in the body. Millets are full of antioxidants, minerals including dietary fibre, iron, calcium and magnesium that are vital for battling a variety of diseases. These are beneficial to include in our daily diet because the grain is healthy and nutritious. They decrease blood pressure, prevent cancer and lessen the chance of tumour growth. The rich nutrient content in millet has many health advantages such as cancer, obesity, lower risk of cardiovascular disease, gastrointestinal issues, migraines and asthma. People utilise millet-based products to fight a variety of nutritional deficiencies and diseases.

Introduction

Soil health and fertility are pivotal to the success and sustainability of agricultural systems. The condition of soil directly influences plant growth, crop yield, and overall farm productivity. A focus on soil health encompasses not just the physical and chemical properties of soil but also its biological vitality, which includes the diverse community of microorganisms, fungi, and fauna that interact within the soil ecosystem. Biodynamic farming, founded by Rudolf Steiner in the early 20th century, offers a distinctive approach to soil health and fertility, integrating organic principles with a holistic view of agriculture that encompasses cosmic and spiritual dimensions. Biodynamic farming is an agricultural philosophy that extends beyond conventional organic practices. It views the farm as a living organism, where soil, plants, animals, and cosmic forces are interconnected and interdependent. This perspective emphasizes that the health of the soil is intrinsically linked to the broader ecological and cosmic environment. According to biodynamic principles, soil fertility is not merely a function of nutrient inputs but a reflection of the overall balance and vitality of the farm ecosystem.

Biodynamic farming is a holistic agricultural system that emphasizes the interrelationship between soil, plants, animals, and cosmic forces. A cornerstone of this practice is the use of biodynamic preparations, which are specialized herbal and mineral formulations applied to the soil, compost, and plants to enhance their health and vitality. This article delves into the origins, development, and specific types of biodynamic preparations, including their ingredients, preparation methods, and application techniques. By exploring both the scientific and spiritual dimensions of these preparations, the article aims to provide a comprehensive understanding of their role in biodynamic farming. It also examines the empirical evidence supporting their efficacy, addresses common criticisms, and discusses future research directions.

Introduction

Biodynamic farming represents a unique and comprehensive approach to agriculture that integrates scientific and spiritual dimensions to cultivate not just crops, but entire ecosystems. Emerging in the early 20th century as a response to the growing concerns over the industrialization of agriculture, this method is grounded in the principles of anthroposophy, a philosophical movement founded by Rudolf Steiner. Biodynamic farming is not merely a set of agricultural practices; it embodies a worldview that considers the farm as a living, self-sustaining organism, where all elements are interrelated and interdependent.

At its core, biodynamic farming seeks to create a harmonious balance between the physical, biological, and spiritual aspects of farming. It emphasizes the importance of the farm’s natural rhythms, including lunar and cosmic influences, which are believed to impact the growth and health of plants and animals. Farmers who practice biodynamics use a variety of unique preparations made from fermented herbs, minerals, and manure to enhance soil fertility and plant vitality, following a biodynamic calendar that guides the timing of sowing, planting, and harvesting.

Introduction

Biodynamic farming is a holistic and sustainable approach to agriculture that goes beyond organic practices, incorporating spiritual, ethical, and ecological dimensions into farming and food production. Rooted in the early 20th century, this method is based on the teachings of Rudolf Steiner, an Austrian philosopher, who laid the groundwork for what has become a global movement aimed at creating a harmonious balance between nature and agriculture. Unlike conventional farming, which often relies heavily on chemical inputs and monoculture practices, biodynamic farming emphasizes the interdependence of all elements within a farming system. This includes the soil, plants, animals, and even cosmic forces. The approach seeks to enhance the vitality of the farm as a living organism, fostering a self-sustaining and self-regulating ecosystem.

Central to biodynamic farming is the concept of the farm as a closed-loop system, where all inputs are produced on-site. This includes composting organic waste, rotating crops to maintain soil fertility, and using herbal and mineral preparations to enhance the health and resilience of the farm. These preparations are often made from specific plants, minerals, and animal manure, which are applied according to a biodynamic calendar that aligns farming activities with the lunar and cosmic cycles.

1. Use of banana pseudostem in fish pond to enhance productivity of f ish: Pseudostems of banana, after harvesting the bunch, are added to the pond by cutting longitudinally, which increases the pH and oxygenation of pond water. This practice increases the fish yield. As it involves low cost, it is being followed by 80% of the farmers in Bastar village of Balasore district in Odisha.

2. ITKs on Craft and Gear Making / Maintenance (Vipinkumar et al., 2013): The major ITKs of scientific rationale identified in the craft and gear making and maintenance were ‘Sardine oil smearing on craft wood for improving the durability’, ‘Smearing cashew kernel oil on craft wood for durability’. Similarly, the durability of cotton nets was believed to be improved by dipping in banpu bark decoction. In the same way, beating nets with thalampu plant for ensuring strength was another one identified in craft and gear maintenance. The scientific validity assessment indicated that the boats of about 6.5 ft size length and 4.5 ft width require 3.5 to 4 litres of oil of sardine. The oil coasts about Rs 70/- per litre. Three cosequitive coatings followed by natural drying under sun are required for good results. Cashew smearing: The boats of about 6.5 ft size length and 4.5 ft width require 3.5 to 4 litres of cashew nut oil and the oil costs about Rs 40 -50/- per litre. Here also three cosequitive coatings followed by natural drying under sun are required for good results. Smearing Cashew kernel oil on craft wood for durability in Karwar of Karnataka is shown in photograph 1. For improving durability of nets, dipping nets in banpu bark decoction was practiced. The thalambu beating is nowadays not practiced due to the non-availability of those items. Instead, fisherfolk use a powder available in the market especially in the net shops. 1 kg of the colour powder (red/ blue) is required for 1 kg of net. The advantage is that the wastage due to mud coating and dirt can be rectified to a great extent.

2. Ventilago denticulata and Syzygium cumini Mixture: In Bori, Shahera, a mixture of asul (Ventilago denticulata) roots and jamun (Syzygium cumini) bark is crushed and administered with water to the suffering animal. This treatment typically cures diarrhea within 2-3 days. Asul is a creeper found year-round in hedgerows, and jamun is a common tree (Dalsukhbhai, 1993).

3. Decoction of Soymida febrifuga: In Shahera, Gujarat, fresh leaves of royan (Soymida febrifuga) are crushed and soaked in water for one hour. A 100-150 ml dose of this concoction is given to the animal, which usually brings relief within 24 hours. This remedy has a long history in the region (Dalsukhbhai, 1993).

4. Ficus hispida: In Panchmahal, Gujarat, roots of dedhumari (Ficus hispida) are washed, crushed, and soaked in water for one hour. The mixture is then filtered through cloth, and 100-200g of the filtrate is administered to the animal. The treatment typically takes effect within a day and completely cures the animal in about 2-3 days. Many farmers use this method, although they may also consult veterinary experts (Baria, 1993).

5. Umra Bark and Banana Plant: During the monsoon, diarrhea in animals is treated using umra bark and banana (Musa Paradisiaca) plant sap. About 500g of umra bark is pounded and mixed with 500ml of banana stem juice. The mixture is filtered, and the filtrate is given to the affected animal. One hour later, the animal is fed 250ml of groundnut oil, resulting in a cure within a day or two (Valsad, Gujarat) (Patel, 1996).

10.1 Multiple transplanting for increasing papaya yield: Papaya seedlings are uprooted and transplanted at a different spot, then uprooted again and planted back at the same spot after fifteen days. This decreases the plant's height and enhances its productive phase (Banaskantha, Gujarat). Kodarbhai (1999).

10.2 Reducing mango flower drop by applying buttermilk and salt: To prevent mango flowers from dropping due to wind and disease, farmers dig a circular trench around the tree trunk during flowering, mix 60-80 liters of buttermilk with 2 kg of salt, and pour it into the trench. After absorption, fresh water is added, and the practice is repeated (Banaskantha, Gujarat). Dudhaji (1997).

10.3 Enhancing fruit set in papaya by inserting a nail in the stem: To induce fruiting in trees that flower but do not bear fruit, farmers insert nails (iron or wooden, 1-2 cm in diameter) into the stem about a foot high (Amreli, Gujarat). Sheldiya (1992).

10.4 Increasing yield of vegetables and fruits by using hair: Waste hair is collected and applied to vegetable, fruit, and ornamental crops. Hair is buried around plants in pits (1/2 kg for ornamental plants, 1 kg for fruit trees) one month after planting and 45 days before fruiting. For vegetables like tomato and brinjal, hair is dispersed during the last ploughing (Tamil Nadu). Subbiah (1998).

10.5 Lemon juice for higher lemon productivity: Farmers increase lemon productivity by spraying a solution of 100 ml lemon juice dissolved in 2 liters of water on lemon trees, ensuring all leaves are wet (Rajkot, Gujarat). Pethan (1997a).

9.1 Plastering Storage area with Lime and Sand: The storage areas, known as Hagevu, are plastered with a mixture of lime and sand. These areas can store 20-30 bags of grain (Heggere and Chitradurga, Karnataka). Nagarathna (2000).

9.2 Indoor Bamboo or Reed Structure for Grain Storage: Indoor storage structures are typically made of bamboo. In regions where bamboo is scarce, farmers use locally available reeds. These structures are cost-effective since they utilize local materials and knowledge, but they do not protect grains from rodents and insects, have a short lifespan, are susceptible to fire, and require frequent maintenance (Andhra Pradesh and Orissa). Navanitha Raju (1999).

9.3 Storage of Onion Bulbs on Bamboo Platform: Onion bulbs can be stored for up to a year on a platform made of loosely woven bamboo strips, raised 2-3 feet above the ground to allow air circulation. The bulbs are piled 2-3 feet high and protected from sun and rain with a cover (Junagadh, Gujarat). Babulbhai (1993).

9.4 Method of Storage of Food Grains in Khanti: A 'Khanti' is constructed in areas with low underground water levels, where a 15-foot deep Khanti can be made. It has a sloping shape with a base 10-15 meters wide and a top one foot wide. A one-foot thick layer of husk mixed with neem is spread at the bottom and sides for pest protection. Different grains can be stored by separating them with layers of husk and large leaves. A Khanti can store 10-15 tonnes of grains from May to November (Maharashtra). Singh (1999).

9.5 Storage of Potato Tubers: Farmers in Hoskote village, Karnataka, store potato tubers in the field on an elevated, hardened soil area of 25 × 4 square feet, supported by 12 stone pillars. A thatched roof provides shade, and a bed of local grass and sugarcane leaves is spread on the floor. Harvested tubers are layered on this bed, with additional layers of leaves on top. The storage is checked for pests every 2-3 weeks. Calotropis gigantea leaves and branches are used around the heap to prevent rodent attacks. This method keeps potatoes cool even in hot conditions (Bangalore, Karnataka). Hannganahalli (1999).

8.1 Medicinal use of Bamboo in Cattle: The important parts of bans (Bambusa arundinacea) used are the leaf and stem, which contain choline, betain, nuclease, urease, cyanogenetic and glucoside. The leaf acts as an emmenagogue, stimulant, astringent, febrifuge, echbolic, and diuretic. It also acts against leprosy, tympany/bloat, diarrhea, retained placenta, threadworm, cough, and cold in horses. Flowering occurs once in ten to twelve years. The plant dries after flowering. (Parabia et al., 2000).

8.2 Medicinal uses of Dendrocalamus Strictus: The leaf and other parts of kaban (Dendrocalamus strictus), which contain siliceous matter, are used as astringent and ecbolics in animals. (Parabia et al., 2000).

8.3 Medicinal uses of Datura metel, D. alba, D. fastuosa: The leaf, root, fruit, and ripe seed of sadah datura (Datura metel) contain alkaloids such as hyoscyamine, hyoscine, atropine, scopalamine, allantoin, and vitamin C. They are used for treating insanity, fever with catarrh and cerebral complications, and the fruit is used to induce heat in animals and treat prolapse of uterus/ vagina. (Parabia et al., 2000).

8.4 Medicinal uses of Dalbergia Sissoo: The stem bark, root, leaf, and mucilage of sisam (Dalbergia sissoo) contain tannin, dalberginone, dalbergin, allylphenol of latitontype, 5,7,4-trihydroxy-s-methoxyisoflorone, and are used for leprosy, boils, eruptions, to allay vomiting, and the oil is used for cutaneous afflictions. Mucilage of leaves mixed with sweet oil is applied in excoriations. (Parabia et al., 2000).

8.5 Medicinal uses of Cyperus Rotundus: The tubers of motha mutha (Cyperus rotundus) have essential oils, myristic and stearic acid, unstable alkaloid, b-seilinne, cyperenone, and are used as diuretic, emmenagogue, anthelmintic, stimulant, tranquilizer, and antipyretic. (Parabia et al., 2000).

7.1 Method of Drying Cucumber and Pumpkin Seeds: Seeds are combined with wood ash and spread on a plate (Thali) under direct sunlight. This accelerates drying by allowing the wood ash to absorb excess moisture from the seeds, preventing them from clumping together (Mandi, Himachal Pradesh). Verma (1998).

7.2 Drying of Millets, Pulses, and Oilseeds on New Moon Days: Grains are sun-dried to remove moisture. This practice is typically carried out on a 'new moon' day, believed to reduce vulnerability to pest damage (Tamil Nadu). Parvathi et al. (2000). Most of the farmers are storing grain in Amavasya (New moon) because it is believed that risk of pest attack is high in the moonlight as compared to new moon. The leaf of Azadirachta indica (neem) and Calotropis procera (madar) are mixed with cow dung. This mixture used as an excel- lent insecticide and pest growth inhibitor (Joseph et al. 2013; Misra 2014).

7.3 Drying Wheat and Maize Cobs Using Indirect Heat: For drying wheat and maize cobs, indirect heat from the hearth (Chullah) is employed. In traditional houses, typically with three floors, the ground floor shelters domestic animals, the first floor serves as living quarters, and above the kitchen lies a storeroom where freshly harvested maize cobs and wheat are placed for drying. Sunlight also aids in the drying process (Kangra, Himachal Pradesh). Verma (1998).

6.1 Hal for Land Preparation: This plough is constructed from Babool, sal, sisham wood, and mild steel. The body and handle are made from one piece, with a separate shoe. It is operated by one pair of bullocks with a yoke, weighs 48 lbs, and can cover 0.8 to 1 acre per day. It works to an average depth and width of 5 and 6 inches in alluvial soils, with a draught requirement of 185 lbs. It is used by 100% of the farming community in Meerut, Uttar Pradesh. (ICAR, 1960)

6.2 Wetland Plough (Dammu Nagali) for Land Preparation: This plough is made from Babool, palmyra, and mild steel, weighing 30-40 kg. Operated by two bullocks and one man, it is attached to the yoke with ropes for puddling rice fields, covering half an acre per day. It has a draught of 200-220 kg and ploughs to a depth of 4-5 inches and width of 5-6 inches in black and red soils. Repairable locally, its annual maintenance costs range from Rs 0.5 to 1.0, with an operational cost of Rs 25 per hectare. It is widely used in the coastal belt of Andhra Pradesh (Guntur and West Godavari). (ICAR, 1960).

IKS stands for Indigenous Knowledge Systems. When applied to pest and disease management in agriculture, IKS refers to the traditional and local knowledge systems developed by communities over generations to deal with agricultural challenges, including pests and diseases.

5.1 Key Aspects of IKS for Pest and Disease Management

1. Traditional Practices: Indigenous communities often have developed practices based on observation and experience to control pests and diseases. These may include specific plant combinations, crop rotations, or timing of planting to minimize pest damage.

2. Natural Remedies: IKS often includes knowledge of natural substances and plants that have pesticidal or medicinal properties. Examples include the use of neem, garlic, chilli, or certain plant extracts to deter pests or control diseases.

3. Cultural Practices: Traditional farming practices may include rituals or timing of activities that are believed to influence pest and disease outbreaks. For instance, planting during specific lunar phases or following certain cultural calendars.

4. Biological Control: Indigenous knowledge may also involve the use of natural enemies of pests, such as predators or parasites, to manage pest populations. This aligns with modern biological control principles.

5. Crop Diversity: Traditional farming systems often promote crop diversity, which can help naturally manage pest and disease pressures by reducing monoculture effects and providing habitats for beneficial organisms.

Seed treatment refers to the application of chemical or biological substances to seeds before planting. This process is designed to protect seeds from diseases, pests, and other adverse conditions that may affect germination and early growth and can improve overall crop yield and quality. Seed treatment can involve the use of fungicides, insecticides, bactericides, and other agents that help improve seed health and vigor. Seed treatment is a crucial step in ensuring healthy crop production. By investing in seed treatment, farmers can achieve better crop establishment and reduce the need for subsequent interventions, leading to more sustainable and cost-effective agricultural practices.

4.1 Importance of Seed Treatment

1. Disease Control: Seed treatment helps to protect seeds and seedlings from soil-borne and seed-borne pathogens, reducing the risk of diseases that can impair seed germination and seedling growth.

2. Pest Protection: Treated seeds are less likely to be damaged by insects and other pests that may be present in the soil. This protection can lead to higher seed survival rates and better crop establishment.

3. Improved Germination: By reducing the incidence of diseases and pests, seed treatment can enhance the germination rate and uniformity of seedlings, leading to more robust and consistent crop stands.

4. Nutrient Provision: Some seed treatments include nutrients or growth promoters that help improve seedling vigor and early development, ensuring that young plants have a better start.

5. Resistance to Environmental Stress: Seed treatments can help seeds withstand adverse environmental conditions such as drought, salinity, and temperature fluctuations, improving the overall resilience of the crop.

Soil fertility management refers to the practices and techniques used to maintain and improve the fertility of soil. Soil fertility is crucial for agriculture because it determines the soil's ability to provide essential nutrients to plants, support their growth, and sustain productivity over time. Effective soil fertility management aims to optimize soil health and productivity while minimizing environmental impacts.

3.1 Key Aspects of Soil Fertility Management Include

1. Nutrient Management: This involves supplying essential nutrients (nitrogen, phosphorus, potassium, etc.) to the soil through organic or synthetic fertilizers to meet the needs of crops.

2. Soil Amendments: Adding organic matter (such as compost or manure) or other amendments (like lime or gypsum) to improve soil structure, water retention, and nutrient availability.

3. Crop Rotation and Diversification: Rotating crops and diversifying plant species can help manage nutrient depletion and improve soil health by reducing pest and disease pressures.

4. Conservation Tillage: Minimizing soil disturbance through reduced tillage or no-till practices helps preserve soil structure, reduce erosion, and maintain organic matter content.

5. Cover Cropping: Planting cover crops during fallow periods or between main crops helps prevent soil erosion, improve nutrient cycling, and enhance soil fertility.

Soil is a loose surface material that provides water, nutrients, and structural support to agricultural plants. It is made up of 45% minerals, 5% organic components, 25% air, and 25% water. Our soils are said to be the source of 95% of the food we eat, either directly or indirectly.

The basis of the food chain is healthy soil. Our soils are the foundation of agriculture and the growing media for almost all plants that provide food. Good crops come from good soils, and healthy crops feed people and other animals. Food quantity and quality are, in fact, closely related to soil quality.

A healthy soil is a dynamic, living ecosystem. It is packed with both microscopic and larger organisms that carry out a multitude of essential tasks, such as nutrient cycling—the process of turning dead and decaying matter and minerals into plant nutrients controlling plant diseases and insect and weed pests, enhancing soil structure, which has a positive impact on the soil's ability to hold water and nutrients, and ultimately increasing crop productivity. Because healthy soil retains or increases its carbon content, it also helps to mitigate climate change.

Traditional agricultural practices have been an integral part of food production in India since ages. These practices have the potential to mitigate the adverse effects of climate change with spatial and sequential diversity (Patel et al., 2020). Traditional Agriculture can be defined as a primitive style of farming that involves the intensive use of indigenous knowledge, traditional tools, natural resources, organic fertilizer and cultural beliefs of the farmers (Abeysekara et al., 2021). It is noteworthy that it is still used by about 50% of the world population. Traditional agriculture can be defined as a set of knowledge- practice-trust nexus which has developed by its adaptive nature and passes on to the next generation through a cultural transmission that explains the relationship between living beings with their environment (Berkes et al., 2000).

The concentration of a true solution refers to the amount of solute present in a given quantity of solvent or solution. It is an important property because it determines the solution’s behavior in chemical reactions, its physical proper ties (such as boiling and freezing points), and its utility in various applications. Concentration can be expressed in several ways, depending on the context and the precision required.

Methods to Express Concentration of a True Solution

1. Molarity (M)

• Definition: Molarity is the number of moles of solute dissolved in one liter (1,000 mL) of solution.

Volumetric Analysis Precautions

1. Use Clean Glassware: Ensure all glassware, such as burettes, pipettes, and volumetric flasks, is thoroughly cleaned and rinsed with distilled water to avoid contamination and ensure accurate measurements.

2. Clean Glassware Properly: Before use, all glass apparatus should be thoroughly cleaned with a cleansing mixture of potassium dichromate (K2 Cr2 O7 ) and concentrated sulfuric acid (H2 SO4 ) to remove any residual contaminants. After cleaning, rinse the glassware thoroughly with distilled water to ensure no traces of the cleansing mixture remain.

3. Proper Calibration: Calibrate all measuring instruments, including burettes, pipettes, and balances, before use to maintain accuracy in measurements.

4. Avoid Parallax Error: When reading the meniscus level in a burette or volumetric flask, ensure the eye is at the same level as the meniscus to prevent parallax error.

5. Use Correct Indicators: Choose the appropriate indicator for the titration based on the type of reaction and the pH range of the endpoint to ensure precise determination of the endpoint.

Buffers

Bronsted and Lowry defined acids as substances which are able to donate protons, and bases as substances which accept protons.

In the above example, BH is an acid because it donates proton and B– is an anion liberated by the deprotonation of the acid. B– behaves like a base, so it is called conjugate base.

Acids can be classified into strong acids and weak acids.

1. Strong acids get dissociated almost completely, e.g., hydrochloric acid, sulphuric acid. This is because the conjugate bases of these acids are very weak (have less affinity for the proton).

2. Weak acids get dissociated partially, e.g., acetic acid, carbonic acid. This happens because the conjugate bases of these acids are strong (have greater affinity for proton). Since the dissociation of the weak acids is partial, the equilibrium constant for the dissociation reaction of the weak acid (BH) can be written as follows:

Analytical Reagents

Chemical reagents are supplied in different grades and each grade has a distinct purpose and range of uses. The purest grade is analytical reagent (AR), the second is laboratory reagent (LR), the third is guaranteed reagent (GR) and fourth is technical grade. Second and third form of reagents have a lot of impurities. Therefore, for the determination of micronutrients, AR grade reagents should be used.

Distilled Water

Distilled water is always used in chemical analysis. The quality of distilled water varies from single distilled water to double or triple distilled water depending upon the requirement of analytical technique(s) e.g. double distilled water (glass distilled) is always recommended for micro nutrient and heavy metal analysis.
