Abstract

Protected cultivation of horticultural crops especially vegetables provides the best way to increase the productivity and quality of vegetables especially during off-season, which also fetches better market price. Yield of some of the vegetables like tomato, capsicum and cucurbits can be increased manifold compared to their open field cultivation. Irrigation management is an important aspect of protected cultivation technology for improving the input use efficiency such as water and nutrients for the cultivation of crops under protected environment such as polyhouse, net house, poly tunnels and nursery production. Various other techniques such as use of mulch can be used to further enhance the water and nutrient use efficiency along with improving the quality of produce and precise resource savings. Automation further reduces the manual intervention and increases the input use efficiency.

Nano-technology refers to technology on a nano- meter scale, specifically less than 100 nano-meters. The novel nano-particles are tiny spheres (fullerenes) or tubes (nanotubes) made from carbon atoms. It facilitates the development of future inventions transversely a vast array of fields. New nano-particles are being made of silicon, ceramic, polymers or even natural ingredients that break down in the body. The characteristics that make these particles functional in the food industry include optical properties, reactivity to temperature, and biodegradability. They can be used as probes or filled with flavorings or nutrients for delivery. Highlights on the categorisation of agriculture with nano- food technology and nutrition are given in Fig 1.

There are three key elements in nano-technology. They are: (1) substances at nano-scale exhibit novel physical and chemical phenomena with novel functions (2) allowing to measure, control and operate material at the nano-scale that transform them to functions. (3) allowing the union of nano scales of materials for exceptional properties.

Introduction

Land is one of the most important resources on which human beings depend. The rate of soil degradation is continuously increasing with the advancement of science and technology, industrial expansion, urbanisation and population explosion. The most important cause of land degradation is the destruction of forests and other vegetation in sloping lands, riverbanks and other areas sensitive to damage (Pramod and Mohapatra, 2012). Anthropogenic activities like over grazing, wood cutting and burning have intensified land degradation, resulting in soil deterioration all over the world (Jin, 2002). Vegetation acts as a protective cover against the forces of wind and water, protecting the soil from being washed or blown away and preserving the physical and hydrographic balance of nature (Jain and Singh, 1998).

Abstract

Doubling the farmers’ income”, implies a 100 per cent growth of the current level of income of the farmers within a specific time frame, through multifaceted efforts of technological advancements in agriculture, policy formulation/ implementation, and efficient market system. The idea of doubling the farmers’ income during seven year period has by many experts been deemed impractical owing to the fact that a consistent annual growth rate of 14.86 per cent would be required in agricultural sector to double its GDP which has never had any history in the Indian agriculture. Some experts point out the possibility of success through appropriate technological intervention and viable government policies specific for each of the agro ecological zones of the nation. Increase in the farmer’s income doesn’t imply increase in nominal income through excessive production, but increase in real income, taking inflation into account. Production technologies, their use and impact are important factors to focus on doubling the farmers’ income. These technologies are already available across all the regions of the country but their adoption remains a problem to discuss always and partial adoption of the technological package can never be expected to get the desired results on ground. The results are suggestive of the pent up need to focus on the extension support on end-to-end approach from production to marketing with appropriate facilitation for inputs, insurance, credit, storage, marketing facilities etc. However, it would need involvement of all the stakeholders to come up on board to pursue this goal.

Abstract

Nutrition is basic to sustainable development being concerned with ensuring food at all times in terms of quality and quantity. As a bridge between food and health it interlinks several variables such as environment and protection from illness and disease, which helps to lead to an optimal quality life. Despite the substantial progress made in India’s food production, serious nutritional challenges continue to threaten her development in human resource development more so rural women are particularly vulnerable to malnutrition. Poor nutritional status of women during adolescence and their resultant vulnerability to anaemia during pregnancy contributes to a higher level of low birth weight children and if it happens to be girl child then the vicious cycle continues. Although food is available through markets at the district and village level, food security at the house hold level becomes a challenge because of lack of purchasing power. Women contribute significantly to agriculture production; on an average their contribution will be around 55-65 per cent. Hence, conscious effort is needed to develop an intervention strategy. One such strategy would be empowerment of women through transfer of technology, which will help in income generation especially during lean agriculture seasons. Priority areas in the field of nutrition for technology transfer would be processing, preservation and value addition of agro based crops. However, training is required for skill upgrading and capacity building of women.

Introduction

The farm to fork approach utilizes agricultural products as raw material for processing by industries to obtained value-added products (Mijinyawa et al., 2007). Processing that transforms animal, vegetable, or marine materials into value-added food products for consumers and forms an integral part of agriculture for storage or size reduction into fine particles. One of the major problems associated with processing is the unavailability of processing facilities including appropriate engineering materials for the transformation of agro-based produce into different forms (Ogwuagwu, 2007). This transformation process mainly includes operations like particle size reduction, milling or comminution, etc. utilizing different size reduction forces without making alterations in chemical properties (Enrique, 2012). This enhances the eating quality or appropriateness of foods for advance processing with a more varied range of available products.

Grains are dried small seeds with adhered or removed husks or outer layers processed for consumption (FAO, 2011). The two major types of commercial grain crops include cereals (such as millet, corn, sorghum, wheat, rye and so on) and legumes (such as beans, groundnuts and soya beans). These grain crops are subjected to a milling operation to break them into smaller pieces or more practically appropriate form. The grinding process involves the application of different mechanical forces to overcome the interior bonding forces bringing change in the state of solid grains to different desirable forms such as flour or meal (Kaul and Egbo, 1985). As a result, the physical state of these grains is modified due to a reduction in size and change of shape (Ryan and Spencer, 2008). Most of the actual milling processing that is used in various industries is based on simple operations. But now various technological progress has been initiated that involves the adoption of computer control for various milling operations to improve efficiency and quality while minimizing labor requirements. Hence, the present text highlights the various technological advancements and evaluation techniques employed in milling operations.

Technological change has been the major driving force for increasing agricultural productivity and promoting agriculture development across the world. In the past, the choice of technologies and their adoption was to increase production, productivity and farm incomes. Over many decades, policies for agriculture, trade, research and development, education, training and advice have been strong influences on the choice of technology, the level of agricultural production and farm practices. Agricultural production today faces several challenges: an increasing world population has to be fed, but at the same time the environment and animal welfare need to be protected. Globalisation has led to increasing international competition, while the agricultural sector is also under heavy economic pressure as a result of regulation. These conditions can perhaps only be met by innovation, be it on the technological or on the systems-level (OECD, 2001). Agriculture is becoming more integrated in the agro-food chain and the global market, while environmental, food safety and quality, and animal welfare regulations are also increasingly impacting on the sector. It is faced with new challenges to meet growing demands for food, to be internationally competitive and to produce agricultural products of high quality. At the same time, it must meet sustainability goals in the context of on-going agricultural policy reform, further trade liberalization and the implementation of multilateral environmental agreements as agreed to by the government.

Introduction

According to FAO (1994), pulses, a subgroup of legumes, are crop plant members of the Leguminosae family that produce edible seeds used for human and animal consumption. Legumes, which are harvested for dry grain, are classified as pulses. Grain legumes are used mainly for oil production, and vegetables are not considered pulses. Pulses are considered the heroes of nutrition as they are an excellent source of key nutrients, including carbohydrates, dietary fibers, protein, vitamins, and minerals, with health-promoting benefits. Pulses are a rich source of essential micronutrients, such as iron, potassium, magnesium, zinc, and B vitamins, including folate, thiamin, and niacin.

Introduction

As per 20th Livestock Census, 2019 goat population in the country was 148.8 million, the second largest species in terms of number after cattle. Uttar Pradesh, one of India’s largest states in terms of population and agricultural activity, boasts a substantial goat population of 14.48 million, which accounts for approximately 9.73% of the country’s total goat population. Goats indeed play a crucial role in many agrarian economies worldwide, including India. In regions where crop and dairy farming may not be as economically viable, goats provide a valuable source of income and sustenance for small and marginal farmers as well as landless laborers. Goats, specifically Capra hircus, possess unique qualities that make them valuable assets in meeting this growing demand for animal protein (Rout et al. 2018). The livestock market has been experiencing significant growth, with global trade presenting vast opportunities for livestock farmers to increase their income. One notable trend over the past decade has been the increasing preference for animal protein consumption worldwide. This shift in dietary habits has led to a surge in demand for meat products, particularly in developing countries where access to protein-rich foods may be limited. The adaptability, diversity, and versatility of goats make them an invaluable resource for agriculture and livelihoods in both developed and developing nations, contributing to food security and economic sustainability in many regions (Mazhangaraet al. 2019).

Salt-affected soils (SASs) are an important ecological entity in world agriculture. It varies with time and space depending on soil, rainfall, irrigation, microtopography, groundwater quality, and depth. Weathering of rocks and minerals, higher rates of evapotranspiration, deposition of wind-blown salt sediments, and seawater ingress are the significant factors contributing to the formation of SASs. Large acreage in canal-irrigated tracts of arid and semi arid areas, which suffers from water logging, is also responsible for secondary salinization. According to an estimate, about 33% of irrigated lands worldwide are affected by varying salinity and sodicity. Other reasons other than improper irrigation that cause soil salinization include deforestation, which results in salt resettling at upper and lower levels, chemical contamination, and air-borne and water-borne salts from industrial outpouring. In addition to soil salinity, the problem of poor-quality water would also significantly increase in the foreseeable future due to planned expansion in irrigated areas and intensive use of natural resources to fulfill the increasing population’s food and other livelihood requirements. Groundwater salinity under irrigated agricultural lands may or may not increase over time. The groundwater salinity will remain the same if the natural river water is used for irrigation. However, if the irrigation water is polluted and contains salts, the salinity of groundwater may show an increasing trend. The rate at which groundwater salinity may increase would depend upon the quality and quantity of recharge water, the depth of the hardpan/barrier layer under the groundwater table, and the substrate’s porosity.

1. INTRODUCTION

Stone fruits belonging to family Rosaceae (sub family-Prunoideae) include several important fruit crops like peach, plum, apricot, cherries, nectarines etc. The World production of these stone fruits is approximately 45.49 million tones; out of which 39.61 million tones stone fruits are grown in Asia and India contributes 6.67 million tones of stone fruits annually. Among all the stone fruits Peach, Plum and Apricot production in world is 24.98, 12.05 and 4.11 million tones, respectively whereas India alone produces 287778, 261903 and 17862 metric tones of peach, plum and apricot, respectively (Table 1). These stone fruits are grown extensively in USA, Spain, France, Italy, Turkey, Morocco, Iran, Africa and Australia. In India, these are grown in J&K, Himachal Pradesh sub-mountainous tracts of Punjab, Uttarakhand, North East States and to the limited extent in the Nilgiris hills. Primarily, these stone fruits are used for table purposes or processed to prepare various types of value added products like jam, jelly, marmalades, preserves, baby foods, nectar, juices, squashes, concentrates, ready-to-serve beverages, wines and also processed into dried products.

Fisheries comprise a major economic activity within complex interactions between human beings and water - ‘the first among equals’ of the natural resources (Ahmed, 1992). Fisheries data assembled by the Food and Agriculture Organization (FAO) suggest that global marine fisheries catches increased to 86 million tonnes in 1996, then slightly declined. In the past three decades, employment in fisheries and aquaculture has grown at a higher rate than the growth of world population. The fishery engineering is evolving as an important domain in view of depleting stocks on both pre and post-harvest scenarios. It will also aid in fish processing technologies, optimizing energy and water use in seafood industries, mitigating climate change related issues and reducing carbon foot print. It is important to explore novel ways to obtain, quantify, and integrate industry responses to declining fishing stocks and increasing management regulations into fishery - and ecosystem-based management advice. The technological interventions help to reduce the wastage of fishes, which is otherwise a highly perishable commodity by preservation technologies and converting it into value added products with higher shelf life. Use of appropriate technologies along the fish value chain will help in producing better quality products and fetch more markets and higher price.

Major areas of technological interventions in the field of fishery engineering cover design and development of fish processing equipment and machineries, energy efficient and eco-friendly solar fish dryers, fuel efficient fishing vessels and fiberglass canoes, indigenous electronic instruments for application in harvest and post-harvest technology of fish, quality improvement of Indian fishing fleet and energy and water optimization techniques for fish processing industries. Focused areas include development of cost effective solar dryers with LPG, biomass, Infra-Red or electrical back-up heating systems, fish de-scaling machines, Fish freshness sensor etc.

Introduction

Main stay of Indian floriculture is to grow traditional loose flowers mostly for worship, personal adornment and traditional decorations. With the evolving culture of ‘saying it with flowers’ the cut flowers sector made significant inroads in recent times. Today the traditional flowers are grown in area of 2.48 lakh hectare producing 16.58 lakh tonnes of loose flower and 4.84 lakh cut flowers (NHB 2015). India also has significant proportion of trade in potted flowering plants, ornamentals foliage plants for landscaping, turf grasses, cut foliage, dry flowers, specialty flowers, annual flower seeds and fillers. India exported floricultural produce worth Rs. 450 core (APEDA 2016) that comprises fresh cut flowers (to Europe, Japan, Australia, and Middle East, USA), loose flowers (for expatriate Indians in the Gulf and Europe), cut foliage (to Europe), dry flowers (to USA, Europe, Japan, Russia, and Australia) and potted plants (Middle East) besides seeds and planting material. The major market for domestic flowers is in Delhi, Mumbai, Calcutta, Chennai, Pune, Bangalore, Hyderabad etc. With limited infrastructure the amount of trade that takes place in the major markets varies from season to season.

Floriculture, the science and art of cultivating flowering and ornamental plants is a dynamic and flourishing sector within global agriculture that encompasses a broad spectrum of activities including the production of cut f lowers, potted plants, bedding plants and foliage. This specialized branch of horticulture not only contributes significantly to the aesthetic enhancement of our surroundings by beautifying homes, gardens and public spaces and is integral to interior design and event decoration but also plays a vital role in economic development, rural employment and international trade. The global f loriculture market is driven by the increasing consumer demand for flowers and ornamental plants, which are integral to cultural traditions, celebrations and everyday life. Flowers symbolize emotions and milestones, making them indispensable in events ranging from weddings and funerals to festivals and personal gifts. Today the traditional flowers are grown in area of 283 thousand hectare producing 2295 thousand tonnes of loose flower and 833 thousand tonnes of cut flowers (Ministry of Agriculture and farmer welfares 2021-22). India plays significant role in the trade of potted flowering plants, ornamentals foliage plants for landscaping, turf grasses, cut foliage, dry flowers, specialty f lowers, annual flower seeds and fillers. India exported flower produce, worth Rs. 707.81 crore (APEDA 2022-23) that consist of fresh cut flowers (to Europe, Japan, Australia and Middle East, USA), loose flowers (for expatriate Indians in the Gulf and Europe), cut foliage (to Europe), dry flowers (to USA, Europe, Japan, Russia and Australia) and potted plants (Middle East) besides seeds and planting material. The major market for domestic flowers is in Delhi, Mumbai, Calcutta, Chennai, Pune, Bangalore and Hyderabad etc. are the major market for domestic flowers in India.

1. INTRODUCTION

Vegetables occupy a prominent position in our diet especially to tone up our digestive system and provide nourishment. Regular use of vegetables, supply many essential health building and protective substances, such as vitamins and minerals. India ranks second in vegetable production in the world. The abundant production of vegetables during the season, results in a glut. Consequently, a large quantity of vegetables gets spoiled resulting in a considerable loss of natural resources. Therefore, preservation is the best way to save the wastage of vegetables and make them available even in the off-season (Plate 1).

India is the largest producer of pulses in the world with 24% share in the global production. During 201011, the total production was 18.09 million tonnes from an area of 25.6 million hectare (Table 1). The important pulse crops grown in India are chickpea (48%), pigeonpea (15%), mungbean (7%), urdbean (7%), lentil (5%) and fieldpea (5%). The major pulse producing states are Madhya Pradesh, Maharashtra, Rajasthan, Uttar Pradesh, Karnataka and Andhra Pradesh, which together account for about 80% of the total production. The pulses production does not keep pace with the domestic requirement and consequently, the nation has to import 23 million tonnes and the per capita availability of pulses has declined progressively from 41.6 g in 1990 to 37 g in 2008 (Indian Council of Medical Research recommends 65 gm/day/capita). Thus, increasing production from the current level poses a serious challenge for the nation.

Even with the best of efforts, pulses production and productivity has more or less remained stagnant. Due to the low productivitylow input nature, pulses are grown as residual/alternative crops on marginal lands after taking care of food/income needs from high productivityhigh input crops like rice and wheat by most farmers. Also, they grow as rainfed crops with little or no modern yield enhancing inputs. The low priority accorded to pulse crops may be related to their relatively low status in the cropping system. As a crop of secondary importance, in many of these systems, pulse crops do not attract much of the farmer’s crop management attention. In deficient soils, the application of micronutrients has also been found to be remunerative, yet the farmers hardly use these inputs. Seeds of newly developed varieties are not available to the farmers in the required quantities. As a result the seed replacement rate is hardly about 2 to 5%. In addition to this, these crops are adversely affected by a number of biotic and abiotic stresses, which are responsible for reduced yield. Lack of onfarm storage facilities and the vulnerability of pulses to store grain pests also results in considerable losses. Stray cattle and blue bulls are responsible for a lot of damage to the pulse crops especially during offseason, thus affecting adversely the cultivation of crops like mungbean, urdbean, pigeonpea, fieldpea and lentil in Bihar, Uttar Pradesh, Madhya Pradesh, Rajasthan and Haryana also resulting in instability and low yields.

India has successfully reduced pesticide consumption without adversely affecting the agricultural productivity. This was facilitated by appropriate policies that discouraged pesticide use and favored IDM application. Despite it, adoption of IDM is low owing to a number of socio –economic, institutional and policy issues. 

A broad range of products and services are required by farmers in order to adopt Integrated Disease Management , calling for close interaction between them, the
scientists and the experts developing IDM technologies. IDM must be based on farmers’ concerns and circumstances.

i) Silicon Technology

Silicon technology in agriculture refers to the use of silicon-based compounds, primarily silicon dioxide (SiO2 ), in pesticide formulations and as part of integrated pest management (IPM) strategies. Silicon technology is not a pesticide itself but is used to enhance the effectiveness of pesticides and contribute to sustainable pest management. Here are some ways silicon technology is applied in pesticide use:

1. Silicon-Based Adjuvants: Silicon-based adjuvants are added to pesticide formulations to improve their efficacy. These adjuvants can enhance the spreading, wetting, and sticking properties of pesticides, ensuring better coverage of plant surfaces and improving the retention of the active ingredient. This leads to more effective pest control and reduces the need for higher pesticide concentrations.

2. Induced Resistance: Silicon has been shown to induce plant resistance against pests. When plants take up silicon from the soil and deposit it in their cell walls, it can create physical barriers that make it more difficult for pests to penetrate plant tissues. Additionally, silicon can trigger the production of defensive compounds in plants, making them less susceptible to pest damage.

3. pH Buffering: Silicon compounds can act as pH buffers in pesticide formulations, helping to maintain the stability and efficacy of the active ingredients over a broader pH range. This can be particularly useful when mixing pesticides with other chemicals or using them in different environmental conditions.
