Abstract

Ectomycorrhizal symbionts are important natural resources to revive degraded and deforested areas. Artificial inoculum of these mycobionts improves the growth of tree seedlings in nutrient poor soils due to the formation of extensive network of fungal mycelium responsible for the transfer of water and nutrients to the plants. Seedlings of tree species like, Pinus insularis, Quercus griffithii and Schima wallichii with ectomycorrhizae formed by Suillus bovinus, Boletus edulis and Scleroderma citrinum were studied in field condition. The study was conducted at two different stages of degraded sites. Results of the study indicated that seedlings with ectomycorrhizae were able to generate numerous lateral roots of greater length and thereby utilize water and nutrients more effectively than non- mycorrhizal ones The degree of mycorrhizal development varied in different host species with different fungal species. There was a strong relation between the colonization by mycorrhiza and the survival of seedlings. The study has suggested that mycorrhiza has a potential in reclamation of soil and reforestation of degraded land. S. bovinus., B. edulis and S. citrinum successfully colonized and promoted the growth of P. insulates Q. griffithii and S. wallichii respectively in reforestation programmes of degraded lands of Nagaland.

Soil, climate and water decide the nature of crop to be grown in a particular region. While soil and climate can be manipulated to certain extent, there is no substitute of water. Water is governed by the hydrological cycle. The major source of water is rainfall which has been reduced over the years due to climate change. The per capita water availability in India was 4944 m3 in 1955 which has been reduced to 1750 m³ now and is expected to come down to 1500 m³ by 2025.

Introduction

In the ancient era, adulteration was practiced as economical fraud like the addition of water to milk and stone to grains and pulses but nowadays it has become a global concern due to adverse health effects of adulterants on a human being. Words like substitution and admixture can help define adulteration. In general, adulteration is defined as either removal of valuable constituents from food or intentionally/ unintentionally addition of substandard quality material to degrade food quality. Food adulteration not only negatively affects the quality of food products but also results in numerous adverse health effects along with significant economic problems (Cheng et al., 2015).

1. Introduction

Law of conservation of mass says that material cannot be created nor destroyed, which is the basic fundamentals of physical science. Many engineering analyses involve material balances. These balances are simply accounting processes that account for all material in processes of interest. The material balance is one of the most useful tools fundamental in the “engineering approach” to design new process. The law of conservation of mass tells that the total mass of all material entering any process must equal the total mass of materials leaving plus the mass of any material accumulated in the process.

Introduction
The term canning refers to a process in which the food is heated in hermetically sealed containers at a specific temperature for a specific time to eliminate microbial pathogens that endanger public health; and microorganisms & enzymes that deteriorate food during storage. The credit for the invention of canning goes to a French confectioner Francois Nicholas Appert, who was awarded a prize in 1809 by the French government for developing a new method of heat preservation of food in a sealed container and after whose name the process of canning has also been named as Appertization. In 1810 Nicholas Appert published the first book on canning entitled “The Art of Preserving Animal and Vegetable Substances for Many Years.” which is the first known work on canning. The work of Appert consists of packing food in glass bottles, closing them with corks, and heating the container in boiling water for several minutes depending upon the type of the food. Although the developed technique was used to preserve different types of food, the actual reason for the prevention of spoilage was known only after the work of Louis Pasteur (1864) who discovered that food spoilage was caused by microorganisms that were destroyed at elevated temperatures and the technique was known as Pasteurization. This understanding helped to form a scientific basis for establishing and revolutionizing the canning industry. Canning of fruits on a commercial scale was introduced in the USA in 1817 by William Underwood. The old phrase ‘necessity is the mother of invention’ suits well for the development of the canning industry during wars. The Civil War in America and the Great European War of 1914 also gave impetus to the development of a canning industry to meet enormous requirements of food for the fighting forces.

Rivers are vital ecological corridors that sustain biodiversity, regulate the water cycle and underpin human civilization by providing water, food, transportation and energy. In India, river ecosystems face mounting threats from pollution, over-extraction, habitat degradation and climate change, necessitating a robust constitutional, legal and policy framework for their protection and sustainable management. The Indian Constitution, through Articles 48A and 51A (g), alongside judicial interpretations of Article 21, has elevated environmental protection (including river conservation) to a fundamental right, reinforced by landmark Supreme Court judgments that embed principles such as polluter pays and the precautionary approach. Key national policies, including the National Water Policy, National River Conservation Plan, and flagship initiatives like Namami Gange, emphasize integrated river basin management, participatory governance, and community engagement. Despite these advances, challenges persist due to fragmented institutional arrangements, enforcement gaps, persistent pollution and the impacts of climate change. Future directions call for legislative reforms, empowered river basin authorities, technological innovations and greater public participation to ensure the ecological integrity and long-term sustainability of India’s rivers for present and future generations.

Abstract

The livelihood security of hill people is closely associated with hydrology of the region. The Himalayas possesses one of the largest reserve resources of freshwater in the form of snow and ice, thereby supporting livelihoods of millions of people. The physiographic constraints of the region restrict irrigation development with the result that, majority of cultivated area remains rainfed. Climate change is also a serious issue concerning hill economy. Its impact on livelihood security is dictated, among other things, through change in hydrology. In addition to highlighting hydrological issues, suggestions are offered on how to deal with water related issues to livelihood enlargement and protection.

In fact, as the concept of synthetic seed involves the use of small propagules and enables the direct sowing of this material in vitro or in vivo, the technology could provide great flexibility to the breeders by not only reducing the costs when large quantities of propagules are required for handling, shipping and planting, but also eliminating the acclimation step when direct sowing in vivo is applied (Onishi et al. 1994).

The artificial seed technology has been applied to a number of plant species belonging to angiosperms. The exact application of artificial seeds will vary from species to species. In self-pollinated crops that currently have good seed production systems, synthetic seeds will not have any practical applications, but in cross pollinating species, especially those where seed production is difficult and expensive, synthetic seeds offer many advantages and opportunities. The importance of encapsulation technique as an aid to propagation in various crop plants has been discussed by many workers. By combining the benefits of vegetative propagation system with the capability of long-term storage and with clonal multiplication, synthetic seeds have many diverse applications in agriculture (Gray and Purohit, 1991; Redenbaugh et al., 1991; Redenbaugh, 1993). In some species seed propagation is not successful. The reason behind this may be due to heterozygosity of seed, small sized seed, presence of reduced or insufficient endosperm, and seedless varieties of crop species like grapes, watermelon, mango, guava etc. Sometimes association of mycorrhizal fungi is essential for seed germination, for example orchids. The germination of these seeds under natural conditions or under control environment is not possible. Propagating of these species through synthetic seed is the added advantage. The possible implications of synthetic seed technology have been detailed hereunder.

6.1. Fungicides

Fungicide originated from two latin words viz., fungus and caedo.

Word caedo means to kill.

Fungicide is a chemical agent which has the ability to reduce or prevent the damage caused to plants and their products.

Physical agents like ultra violet light and heat should also be considered as fungicides.

Antisporulant and fungistatic compounds do not kill the fungi, they are included under the broad term fungicide

Introduction

Poultry are domesticated birds mostly reared for the purpose of meat and egg consumption as well as for their feathers. It includes chickens, quails, turkeys, waterfowls, ducks and geese. The endocrine system of poultry consists of hypothalamic-hypophyseal complex, parathyroid gland, thyroid gland, pancreatic islet cells, adrenal glands, ultimobranchial glands, endocrine cells of gut and the gonads. These endocrine organs release hormones into the bloodstream. Peptide hormones act on the surface of cells, whereas steroid hormones act on target tissues by entering in the cytoplasm or nucleus of cells. Lack of diagnosis in the case of endocrinopathies is a major cause of production loss globally. Advancement in awareness, diagnosis, treatment as well as management is critical to ensure optimal flock health. Cost-effective programs of biosecurity and vaccination are required to prevent or limit the impact of disease. Programs of emergency treatment and long-term prevention are justified for severe endocrine diseases which have a profound impact on production.

Introduction
Fruit juice and beverages comprise naturally extracted juices, drinks, ready to serve (RTS) beverages, carbonated juice drinks, nectars, squashes, cordials and appetizers, etc. These products are highly refreshing, thirst-quenching, appetizing and nutritionally superior to many synthetic and aerated drinks. Fruit juice is the natural liquid expressed from the edible portion of the fruit. Fruit juices are generally extracted from fruits in several ways, depending on their structure and composition. Soft fruits such as berries or tomatoes can be pressed in a fruit press or pulped by using a juicer attachment to a food processor. Citrus fruits are usually reamed to extract the clear juice. Harder fruits, such as pineapple, are peeled, pulped and pressed to extract the juice. Apple and pear fruits are crushed in a fruit grater and pressed in a hydraulic/ basket press to extract a clear juice. Passion fruit juice is prepared by using a pulper-finisher that separates the skin and seeds from the pulp. The fruits like mango, guava, apricot, peach etc from which the clear juice extraction is difficult are passed through the pulper to make pulp and then the pulp is utilized for preparation of juice, fruit drinks and ready to serve beverages. The composition of juice is unaltered during preparation and preservation while for fruit beverages like drinks, squashes, cordial etc the fruit juice or pulp, sugar, acid, colour, flavour etc are mixed in appropriate proportions to a desirable taste. Apple juice, orange juice, mango squash, guava drink, pineapple juice and squash, mixed fruit drink, mango nectar etc are the commercial products available in the market.

Introduction
Plant being sessile are subjected to a myriad of biotic and abiotic stresses that impede growth and resulting significant losses in crop productivity globally (Bhat et al., 2019; Ganie & Reddy, 2021). In this context, there is an immediate need to develop high yielding climate-resilient crop varieties for ensuring food security in the face of increasing population growth. Although conventional breeding has achieved notable success in the development of high-yielding crop varieties (Bhat et al., 2020), but this approach is slow to maintain pace with ever increasing population. In this regard, more recent approach of genomics-assisted breeding (GAB) has emerged as a pivotal approach to develop the high-yielding climate resilient crop varieties (Bhat et al. 2021). Although, low-throughput sequencebased markers like simple sequence repeats (SSRs) have been extensively utilized in molecular breeding programs, but they have the limitations of reduced genomic coverage and high cost (Varshney et al., 2014; Zargar et al., 2015). In this context, the emergence of second-generation DNA marker systems has provided higher genomic coverage and low cost in marker-assisted breeding. For example, recent advancements in next-generation sequencing (NGS) and genotyping platforms have substantially enhanced marker density and genomic coverage while reducing costs (Przewieslik-Allen et al., 2019); thus rendering them commercially available for both model and non-model crop species (Huang & Han, 2014; Rasheed et al., 2017). These high-throughput genotyping platforms provides millions of DNA polymorphisms (Bassi et al., 2016; Ganal et al., 2012), thereby enhancing gene mapping resolution and prediction accuracy in genomic selection (GS) (Robertsen et al., 2019; Yu et al., 2019). Most of the agriculturally important crop traits, such as yield, quality, and stress tolerance, possess complex inheritance i.e., governed by multiple genes with minor effect on trait of interest as well as are highly influenced by genotype-by-environment (G × E) interactions (Voss-Fels & Snowdon, 2016). The conventional linkage mapping approach has elucidated the genetic basis of agriculturally important complex traits but this approach involves the use of bi-parental mapping populations which are constrained by the limited genetic diversity, low resolution, and restricted recombination events (Brachi et al., 2011; Collard et al., 2005). Consequently, the genome-wide association study (GWAS) has emerged as a powerful approach for dissecting the genetic basis of complex quantitative traits in crop plants, resulting higher resolution and allelic diversity (Varshney et al., 2020; Zhu et al., 2008). Moreover, owing to the availability of cost-effective and high-density genotyping platforms, has allowed the routine use of GS in the crop breeding which is more recent approach of GAB (Crossa et al., 2017). In recent years, the advent of next-generation sequencing (NGS)-based genotyping techniques has significantly allowed the genotyping of extensive germplasm collections, enabling comprehensive GWAS and GS analyses (Annicchiarico et al., 2017; Zargar et al., 2015). Nonetheless, the predominant limitations impeding the utilization of SNPs in the GWAS and GS approaches encompass their inherently biallelic nature, the occurrence of rare alleles, and the prevalence of linkage drag (Voss-Fels & Snowdon, 2016; Wray et al., 2013).

Abstract

The paper presents findings of a field study to determine the agricultural and socio-economic impact of climate change on the mountain farmers’ apple economy. The study investigates the positive and negative effects of climate change on mountain farmers’ economy. It revealed how mountain farmers in a valley were forced to abandon apple farming which destroyed their farm economy and at the same time how same climate change brought new economic opportunities. The study findings also indicate that opportunities brought by climate change seem to have a time scale. This research attempts to piece together evidence and aims to enhance our understanding of climate change impacts as observed by farming communities at very local levels. The growing threat of global warming and its effects and prevailing obscurities about the future of agriculture are all addressed in this investigation.

5.1 Sampling

There are different sources of water such as rain, streams, canals, lakes, tanks, ponds, large reservoirs, shallow and deep wells, shallow and deep tube wells, as well as sewage effluents and sea water. The composition of the different sources of water vary with the season, rate of flow, the extent of effluents from the industrial units and sewage effluents from the municipal area during rainy season, the river tank and pond water becomes salty and muddy due to soil erosion. The depth of ground water also varies with the seasons. The sources of water available to the farmer for irrigation of crops are generally few such as canal, shallow and deep wells, pumping sets, tube wells and runoff water collected in excavations along roads, natural drains and adjoining areas under impeded drainage. The composition of water also varies with the season. Whatever may be sources of water, the water sample is taken along with the soil sample to soil testing laboratory for its analysis by way of assessing the suitability of water for irrigation.

For drawing maximum benefit the samples taken be representative of the water in bulk and it should be collected in a clean vessel. One to three litres capacity plastic bottles duly washed with a detergent are satisfactory. However, before filling with water samples the bottles must be rinsed with water samples three times. The information such as farmers name, owner of pumping sets, date and month of sampling depth of ground water, crops and soils being irrigated, any specific agricultural or human problems encountered to be briefly recorded along with the name of village, block, tehsil and district. The water sample should be properly labeled and submitted to soil testing laboratory for its analysis.

All of nature’s biodiversity is not visible. Biodiversity can also not be studied and/ or understood by looking at and analyzing it with the naked eye. A great proportion of the planet’s biodiversity flourishes in the ecosystems not directly accessible to us and the organisms in the sizes our eyes cannot record. The soil biodiversity is more interesting and more varied than we have understood and appreciated. The biodiversity in the soil - together with the physical environment - constitutes what we can call the pedosphere. Biodiversity in the pedosphere is distinguishable from that of the biodiversity above the soil surface. One is nonplussed by an understanding of some of the unbelievable features and functions of the pedosphere biodiversity.

The Convention on Biodiversity (CBD) held on the occasion of the historical Earth Summit in Rio de Janeiro in 1992 underlined the significance of biodiversity conservation for various tangible and non-tangible benefits as well as one of the key factors for sustainability. However, the conservation of soil biodiversity for realizing sustainability

Financial inclusion, which is the process of accessing and properly utilizing formal financial services, is an important factor in powering economic development and poverty reduction. Study undertakes a broad cross- country analysis of financial inclusion and its impact on social and economic factors. Applying data from respectable bodies like World Bank, International Monetary Fund, Eurostat and United Nations Development Programme, the study applies regression analysis and fixed effects models to determine how income, employment, income inequality, urbanization and human development affect financial inclusion. The outcomes show the complicated interplay between these actors and financial inclusion over various national situations.Financial inclusion is becoming a key component of equitable economic development and poverty alleviation worldwide. The importance of financial inclusion is undisputed, but its causes must be identified. This research article uses a comprehensive cross- country analysis to explain how various civilizations utilize financial services. The study will examine the relationship between financial inclusion and its key socio-economic factors— income levels, employment dynamics, income inequality, urbanization trends, and human development—to inform inclusive economic development policymakers, researchers, and practitioners. The data demonstrates that financial inclusion promotes economic development by helping people save, invest, and manage risk. Additionally, academics have focused on socio-economic issues including income distribution, urban-rural divide, and education level in shaping financial inclusion patterns within and within nations. These characteristics’ effects on financial literacy are yet unknown, thus more empirical study is needed to develop evidence-based policy.

Introduction and Relevance
UHT processing of milk was developed to produce a shelf-stable product with minimal chemical changes as encountered with sterilized milk. Aseptically packaged UHT milk can have a shelf life of 06 to 12 months and does not need to be stored in a refrigerator. Its role in the market varies by region. In countries like the India, USA and Canada, where UHT milk occupies a smaller segment of the liquid milk market, it is often used as a backup option, reserved for situations when pasteurized milk is unavailable. Conversely, in regions such as Europe, (particularly France, Belgium, Spain and Germany), Asia, (China, Japan, Thailand and Vietnam) Latin America and (Brazil) in UHT milk is the dominant form of milk available and is consumed regularly. In markets where it is a backup option, UHT milk requires long-term stability of 6–12 months, while in regions where it is used daily, a shorter shelf life of three months or less is often sufficient.
Ultra-High Temperature (UHT) treatment involves heating milk to very high temperatures, typically between 130°C and 150°C, for a brief period of few seconds. This process results in commercially sterile milk, meaning that while not all bacteria are destroyed, those capable of growing under ambient storage conditions are effectively eliminated. An essential component of UHT processing is aseptic packaging, where the sterilized milk is filled into presterilized containers in a sterile environment. This combination ensures that the milk remains free from contamination and maintains its extended shelf life without requiring refrigeration.
Standards for UHT processing vary globally. In the European Union, a minimum temperature of 135°C with an appropriate holding time is mandated. In the United States, the standard for ultra-pasteurization is 280°F (137.8°C) for 2 seconds. Many international standards recommend 135°C for at least 1 second, though some countries do not specify minimum conditions. However, this level of treatment is often regarded as insufficient for completely destroying the spores of spoilage organisms, highlighting the importance of precise temperature-time combinations and the critical role of aseptic packaging in ensuring product safety and stability.
