Abstract

Wheat rusts, caused by Puccinia spp., are one of the major constraints for sustained wheat production. Significant progress has been achieved in the management of wheat rusts and understanding of wheat-Puccinia host-pathogen systems. The key research frontiers of wheat rusts research comprised disease epidemiology, the discovery of novel sources of resistance and their transfer into superior cultivars, pathogen surveillance for monitoring the virulence profiles of variants of rust pathogens, and the application of genomic technologies in cereal rust research. This chapter gives an overview of the research and development outcomes achieved to minimize the yield losses caused by wheat rusts during the last 90 years in the Indian subcontinent. Wheat rusts have been mainly controlled via genetic means; however, an integrated approach by combing the fungicides was carefully considered when needed. All efforts of managing wheat rusts in the future must cover the identification and transfer of genetically diverse rust-resistance sources with a reputation of durability into agronomically superior genotypes. The understanding of wheat rusts epidemiology globally and the region-specific virulence pattern of Puccinia spp. should be considered for gene deployment. The next-generation tools such as CRISPR-cas9 and other genome editing approaches are likely to be part of wheat rust management within a few decades.

Introduction

Non-coding RNAs (ncRNAs) are RNA molecules that do not code for proteins. They are transcribed from DNA and can be categorized into two main types: long non-coding RNAs (lncRNAs) and small non-coding RNAs (sncRNAs). While sncRNAs are shorter than 200 nucleotides, lncRNAs are usually longer than 200 nucleotides. Non-coding RNAs have been found to play important roles in a variety of cellular processes, including gene expression, cell differentiation, and development.

Abstract

Carbohydrates are the primary product of photosynthesis and key source of energy in plant and therefore play important role in plant growth and development. Plant carbohydrates are classified into two categories structural carbohydrates and Non-structural carbohydrates (NSCs). NSCs are main component of vegetative tissue and inside the cell they are present in plastids, cytosol, apoplast and vacuoles. Starch is the storage carbohydrate and is used in unfavorable condition on other hand soluble sugars support functions like supporting new growth and defense as they are intermediary metabolites, osmolytes, and substrates for transport. Under unfavorable condition carbon assimilation is less than the plant demand and under such condition these NSC act as “food pantry” which allow sessile plants to cope up unfavorable condition. Pattern of NSC accumulation may also differ for canopy/distal branches, stems and roots, depending on how drought has affected transport of NSC within the plant. These NSCs protect plants during desiccation and against freezing damage by stabilizing proteins complexes and membranes. Thus, NSCs are important carbohydrates for the growth and development of plant during normal as well as in stressed condition.

Abstract

The waste utilization as derivative from different food processing sector has been emerged as the main challengeable problem around the world due to the generation of by-products at large quantities consisting seeds, peels, rags, unused flesh, bran, husk, germ, stalk etc. during various processing chain steps. Though these food by-products are potentially rich source of natural compounds which finds its wide utilization in different industries as affordable, cost-effective, novel ingredient comprising dietary fiber, phytochemicals, antioxidants, pectin, enzymes, organic acids, food additives, essential oils etc. subsequently after extractions, purified fractionation and fermentations methods. These food byproducts also have pharmaceutical and nutraceutical activity. A nutraceutical is like a medicine or food grade product, which not only provides physical benefits and nutritional supplements but also protects against various chronic diseases. This food processing waste utilization should be a topic of interest, by means of two ways, i.e., through waste quantity reduction and increased value-added food products production and also as renewable energy source. The purpose of this study is to highlight the opportunities to utilize food by-products from various food processing industries and to encourage the vital exploitation of the by-products containing large number of bio-active compounds having nutraceutical potential.

Abstract

The current photosynthesis of flag leaf is the most crucial source of assimilates that are essential for grain development in wheat. Translocation of these assimilates from the leaf to grain takes place in the form of sucrose. However, environmental cues that influence assimilate balance between the leaf and the developing grain which act as source and sink respectively determine grain yield prospects of wheat. The assimilate translocation system that links source and sink can also play a significant role. Hence, this aspect of assimilate supply has been a focus of research over the past few decades for crop improvement particularly under abiotic stress environment that tend to alter source-sink balance by impairing physiological and developmental processes in plants. Grain growth is mainly triggered when the primary assimilates meet the metabolic needs of the developing grains through the current photosynthesis or through assimilates stored in the form of Non-structural carbohydrates in stem. Hence, the improvement of photosynthetic capacity to synthesize sucrose, its storage remobilization, and utilization becomes imperative under abiotic stresses. Various aspects of Non-structural carbohydrates in wheat stem have been estimated, and efforts have been made to reveal the mechanisms of assimilate partitioning. In this context this chapter discusses strategies to improve grain yield with greater insights into the photosynthetic carbon assimilation, the pathways actively involved in the transport of sucrose from source to sink and their utilization at the sink organ. The information related to assimilate supply to the developing wheat grain under high temperature and drought stress conditions can provide opportunities to translate this knowledge into traits for improvement of climate resilience in wheat.

Food security is a pressing global concern that requires immediate attention. The rapid pace of urbanization and industrialization has resulted in a reduction of available land for agriculture, making it increasingly difficult to meet the growing demand for food. In countries like India, where there is already a shortage of meat, rabbit farming has shown great potential in helping to bridge this gap.

India deposited its instrument of accession on 7 September 1998 to both international treaties of WIPO in Geneva i.e. Paris convention for the protection of Industrial Property and Patent Cooperation treaty. PCT provides a system for filing a patent application and allow us to obtain patents in multiple countries around the world on the basis of a single patent application.

Horticultural commodities are highly perishable because they remain physiologically active after harvest and are susceptible to moisture loss, respiration, microbial deterioration, mechanical injury, and physiological disorders. This chapter introduces principles of harvesting maturity, handling, grading, sorting, packaging, storage, transportation, and cold-chain management. Appropriate post-harvest practices help preserve freshness, nutritional quality, appearance, and market value while reducing losses. The chapter also examines value addition through processing, drying, preservation, packaging, and development of new horticultural products. Efficient post-harvest systems connect production with consumers and markets and are particularly important for high-value fruits, vegetables, flowers, spices, and other perishable commodities. Together, improved technology, quality management, and value addition can significantly increase farmer income and strengthen horticultural value chains.

Changes in philosophy about plant disease management

To achieve reasonable and sustainable results crop disease management philosophy should shift focus from

Management of pathogens (or insect vectors) to managing host plants.

A single goal of high productivity to multiple goals of high yield, efficiency, quality and safety.

3.1 Overview

3.1.1 Rice straw: What is it?

When harvesting paddy rice, rice straw is produced as a by-product. Approximately 0.7-1.4 kilograms of rice straw can be obtained for each kilogram of milled rice, depending on the variety, moisture content during harvest, and cutting length of the remaining plant stems. The rice straw is separated from the grains after the plants are threshed manually using stationary threshers or with modern combine harvesters, as shown in Figure 3.1.

Rice straw is a type of lignocellulosic biomass comprising cellulose, hemicelluloses, and lignin. Figure 3.2 illustrates that pretreatment can be used to separate these components. Unlike lignin, which is found in the cell wall, cellulose and hemicellulose are organic fibers.

Abstract

6.20. Role of Micro Nutrients in Vegetable Production 6.20.1. Born 6.20.1.1. Importance Warington first demonstrated the essentiality of boron in plants in 1923 in broad bean (Vigna fava L.). Boron markedly affects nitrogen uptake and the metabolism of nitrogen compounds. The protein contents of young leaves decrease and soluble nitrogen compounds, particularly nitrate accumulate under the condition of severe boron deficiencyBoth with and without boron added, nitrate reductase activity was obviously higher with Ca (NO3 )2 than with (NH4 )2 SO4 . With boron added, nitrate reductase activity in leaves increased from the basal to the top parts of the plant.

Abstract

Bioprocessing is much greener than chemical methods, since biocatalysts (enzymes or cells) involved are extremely selective, producing higher product yield with less or no by products, which are basically difficult to separate. Biotechnology can offer both economic and environmental benefits to the chemical industry and thus has great potential to achieve the sustainable production of existing and new products from renewable feedstocks. Fuel and energy production from biomass are major market sector for bioprocessing. They are considered in the manufacturing of biopharmaceuticals, food, food additives, chemicals, and several other products. Generally, a bioprocess involves feedstock pretreatment, fermentation or biocatalysis, and downstream processing for obtaining product and its purification. It is explored for the production of xylitol, fatty alcohol, butanol and biorefinery. Deep understanding of the process is required to create robust control strategy. Based on the requirements, sophisticated instrumentation and complex control laws or simple control law having intricate monitoring system can be selected. Supercritical fluids (SCFs) are advantageous for bioprocessing due to its transport properties, high diffusivity and low viscosity facilitate mass transfer phenomena, variation of pressure and/or temperature are adjusted providing high flexibility in the extraction of metabolites from cells. Microfluidic devices in which small amounts of fluids (10^-9 and 10^-18) are manipulated have emerged for high throughput applications. Automation of the optimization processes is enabled through microtiter plates with simplicity and operate with very small volumes. Therefore, more research is necessary to develop integrated processes that will allow combining one or more techniques to enhance bioprocessing at lower costs.

With ongoing advancements, fermentation technology continues to open new avenues for innovation and contribute to a more sustainable and environmentally conscious future. The present chapter compares types of fermentation process as well as gives an insight into various industrial prospects of fermentation technology.

Abstract

Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms; yeasts or bacteria under anaerobic conditions. Fermentation usually defines the desirable action of microorganism to enhance food safety by inhibition of pathogens, modify their sensory properties, improve their nutritional value by removing anti-nutritive compounds and by enhancing bioavailability of components. Pulses and Legumes are the major source of dietary nutrients all over the world. Fermentation can be the most simple and economical way of improving their nutritional value, sensory properties and functional qualities. Pulses and legume based fermented food products offer opportunities to include probiotics, prebiotics and fibers in the human diet. In the Indian subcontinent, making use of fermented food and beverages using local food crops and other biological resources is very common, although the nature of the products and the base material varies in different regions. This chapter focuses on some of the indigenous fermented foods produced in the country that have not received the scientific attention they deserve in the last decades. Products produced from different pulses and legumes substrates fermented by lactic acid bacteria, yeast and/or fungi are included.

It explains the relationship between quality assurance, quality control, food safety, documentation, and management systems such as HACCP and ISO-based frameworks. The chapter also examines QA department structures, monthly reviews, audits, digitalization, quality culture, and performance indicators. By integrating prevention with measurement and accountability, the chapter demonstrates how effective QA can protect consumers, reduce losses, improve consistency, and strengthen profitability.

8.1 Recommendations

The specific recommendation for NAZ in promoting CA are

• Since fragmentation has come out as a barrier to CA, the community based CA entrepreneurship will be more successful to make CA ecologically resilient, economically viable and socially adoptable.
• Crop residues are viable source for soil nutrients including organic carbon replenishment, but unfortunately left over crop residues are either burnt out or wrongly used. So, a community bank on crop residues in the form of bio-parks on a commercial basis can be a dependable source of organic manure for being blended into the farm soil. Auditing on volume of disposable CR and its proper application can help in making operating farm more resilient and productive.
• Since CA farmers have to go through a minimum gestation period and they are expected to contribute to the ecological resilience and carbon sequestration, economic incentives must be extended for their productive as well as stewardship function. A policy promulgation is the need of the hour to support their contribution
• Since fragmentation of holding poses a potential threat to resource energy biodiversity and economic conservation, so a strong land and farm policy needs to be there to abate disintegration and fragmentation of holding

A cow is called repeat breeder when it has failed to conceive even after three or more number of services, has normal estrus cycle length, no abnormal vaginal discharge, no palpable abnormality in the reproductive tract, has calved at least once before and is less than ten years of age. Repeat breeding is one of the most important infertility problem faced by field veterinarians.

Causes

1) Fertilization failure

2) Early embryonic death

Main Points that Need to be Known by a Farmer About Repeat Breeding Cow

• Signs of estrus like vaginal discharge and its color, bellowing, mounting etc

• Time of estrus as observed by owner (morning, evening etc)

• Vaginal discharge whether clear or mucopurulent/purulent

• Duration of estrus

• Inter-estrous interval

• Number of inseminations
