Transportation and distribution of fruits and vegetables are important stages   of post-harvest loss. In India,  transportation of perishable commodities is in the most precarious stage. For local market, the produce is brought either by bullock cart or tractor trollies. The long distance transportation is mainly by rails and trucks, which is very costly. The basic reason for preference to road transportation is that it takes short transit period.

Soil regeneration is about bulding or making topsoil. It is a particular form of ecological regeneration within the field of restoration ecology is the act/idea of replenishingthe top soil with beneficial nutrients casing natural methods. Time required from inorganic to organic would be about 60 to 200 days depending upon the situation. Once the inorganic fertilization is stopped, following actions facilitate quick conversion:

• Apply Farm yard/Poultry manure available in the farm as a basal dressing.
• Sow 25 kg of multi varietal seeds (MVS) in one acre.
• Allow it to grow up to 60 days.
• Inoculate the soil with the bio-agents like Azospirillum, Phosphobacterium, Pseudomonas flouresens, Trichoderma viride on 30 days after sowing (DAS).
• Incorporate in situ 60 DAS (30 t ha^-1 biomass is generated on 60 DAS) green manures.

8.1 INTRODUCTION

Orchard is a place or a piece of land where different kinds of fruit plants are planted in orderly manner and managed efficiently for production of successive yield to get assured economic return. An orchard being capital-intensive and long-term venture careful planning, layout, selection of site, preliminary operations etc. are to be done. It is easy to establish an orchard considering its features critically but difficult to manage afterwards. It needs high managerial skills and technically skilled manpower to carry out different orchard operations. Any lapses in management can lead to incur heavy loss.

5.1. Diffusion

Process by which an innovation is communicated through certain channels over time among the members of a social system.

Introduction Nanoscience is a competitive and trending concept in present scientific community, especially in agricultural and allied sciences. The usage of nano-sized materials in food processing sector spreading slowly. With the passage of time and innovation continuation in nanotechnology creating interest to develop miniaturized sensors. Miniaturized sensors have lots of benefits like reducing bulkiness with low power consumption and this eventually reduces the cost. Generally inorganic semiconductors are widely used to develop nano sensors. Generally, sensors are composed of two basic unit which are an identification element and a signal transducer element. Due to its simple structure, high portability and low price, can benefitted against disadvantages of existing system, which are costlier and much more popular. High portability, ease of placement and use make it suitable for onsite use with real-time monitoring. Also, helps in qualitative and quantitative analysis of such substances during analysis of foods which may cause danger and thus inhabit a wider research and development space. For the detection of different unwanted materials or compositions in food, various chemical or biological sensing devices based on different working principles have been developed. The carbon-based nano material can be categories as Ordered Mesoporous Carbon, Carbon Nanotubes, Graphene and Its derivatives, and Carbon Dots.

The central tendency measure is defined as the number used to represent the center or middle of a set of data values. The three commonly used measures of central tendency are the mean, median, and mode.

Measures of location (averages)

The term average refers to any one of several measures of the central tendency of a data set.

• The mean has the disadvantage that its value is influenced by outliers. An outlier is an observation whose value is highly inconsistent with the main body of the data. An outlier with an excessively large value will tend to increase the mean unduly, whilst a particularly small value will decrease it.

• The mean is an appropriate measure of central tendency if the distribution of the data is symmetrical.

The mean will be ‘pulled’ to the right (increased in value) if the distribution is skewed to the right, and ‘pulled’ to the left (decreased in value) if the distribution is skewed to the left.

shrubs with crops and livestock in ways that create diverse, productive, and sustainable land-use systems. In natural farming, where minimal chemical inputs are used, agroforestry offers numerous environmental and economic benefits, making it a valuable approach for sustainable agriculture.
1. Soil Health and Fertility
Soil health and fertility are the cornerstones of any sustainable agricultural system, particularly in natural farming, where synthetic inputs are minimized or avoided altogether. Agroforestry, an agricultural practice that integrates trees and shrubs into farming systems, plays a key role in maintaining and enhancing soil health and fertility through natural processes. Here’s how agroforestry significantly improves soil conditions and sustains fertility over time. One of the primary ways agroforestry enhances soil fertility is through nutrient cycling. Trees and shrubs shed leaves, twigs, and other organic matter onto the soil surface, forming a layer of mulch. As this organic matter decomposes, it releases essential nutrients such as nitrogen, phosphorus, and potassium back into the soil, which are then available for uptake by crops. This process mimics the natural nutrient recycling seen in forests, reducing the need for chemical fertilizers and supporting the goal of low-input natural farming. Some tree species used in agroforestry are nitrogen-fixing, such as certain types of legumes like Gliricidia and Leucaena. These trees form symbiotic relationships with nitrogen-fixing bacteria in their root nodules, converting atmospheric nitrogen into forms that plants can use. As a result, these trees contribute nitrogen directly to the soil, boosting its fertility and helping to meet the nitrogen needs of companion crops without synthetic fertilizers. Agroforestry improves soil  structure by encouraging the formation of stable soil aggregates.

This chapter introduces systematic approaches for controlling biological, chemical and physical hazards throughout the egg chain. It explains the seven principles of HACCP and their application to shell eggs and egg products. Prerequisite programmes, GMP, GHP, FSSAI regulations, international regulatory frameworks, traceability, recall management and risk communication are discussed. A worked HACCP plan for liquid egg demonstrates how hazards and critical control points can be identified and controlled. The chapter emphasizes that egg safety requires an integrated farm-to-fork approach rather than relying solely on processing-plant controls.

This chapter is an extensive survey of all past studies relevant to the field of investigation which gives knowledge of what others have found out in the related field of study. In any scientific investigation or research, a comprehensive presentation of the review of literature is a statutory requirement. Its main functions are to develop a better understanding of the problem to be investigated, delineate a new area of study and avoid unnecessary duplication, decide on the tools and techniques to be adopted including developing some new ones, also to relate the present study with the previous ones by finding out the areas of agreement and disagreement.

The review of literature of the present study is based on the major concepts related to the field of investigation. As direct references on the entire item are not in abundance, certain specific references along with some indirect references have been incorporated in this chapter for the purpose of meaningful use.

Fungicides are chemical compounds or biological organisms used to kill or inhibit the growth of fungi and their spores. They are essential tools in agriculture and horticulture for protecting crops and plants from fungal diseases, which can cause significant yield losses and economic damage.

Fungistat: Some chemicals do not kill the fungal pathogens. But they simply arrest the growth of the fungus temporarily. These chemicals are called fungistat and the phenomenon of temporarily inhibiting the fungal growth is termed as fungistatis. Antisporulant Some other chemicals may inhibit the spore production without affecting the growth of vegetative hyphas and are called as ‘Antisporulant’. Eventhough, the antisporulant and fungistatic compounds do not kill the fungi, they are included under the broad term fungicide because by common usage, the fungicide has been defined as a chemical agent which has the ability to reduce or prevent the damage caused to plants and their products

Introduction
Antibiotic-resistant E. coli develops as a result of the heavy use of antibiotics in the production of food animals, which is then found in the meat from those animals. There have been reports of a number of antimicrobial resistant E. coli infections linked to the ingestion of tainted milk and chevon. As a result, the existence of antibiotic resistant E. coli is a significant and expanding global public health risk. Escherichia coli of animal origin has also been seen to colonise humans, and because it is resistant to many conventional antibiotics, it can cause serious illnesses for which there are few effective treatment choices. Due to its ubiquitous presence in the environment, E. coli has traditionally been recognised as the main vehicle for the transmission of various antibiotic resistance genes and vectors.Extended-spectrum beta-lactamases (ESBLs), which can make the bacteria resistant to some frequently used antimicrobial treatments, are tiny proteins (enzymes) that some strains of E. coli have been shown to manufacture under favourable conditions. A major issue around the world is the emergence of different E. coli strains that produce ESBL in foods that come from animals that are raised for food. The ESBL enzymes TEM, SHV, and CTX-M from Group A have been widely reported to be generated by E. coli and have been shown to hydrolyze ampicillin, carbenicillin, oxacillin, and an extended spectrum of cephalosporins, including ceftazidime and cefotaxime.
Extended beta spectrum lactamase producing E. coli
The occurrence of antimicrobial resistance and the presence of corresponding resistance genes in the environment is an ancient phenomenon. This is largely due to the fact that many of today’s antimicrobial agents are derived from natural precursors produced by soil bacteria such as Streptomyces. These natural compounds likely evolved to mediate microbial competition for

Electronic resources for libraries includes online databases , electronic( e-) journals , electronic(e-) books ,full text articles and web sites, where online journals have firmly established themselves as essential resources for libraries and information centers  and their users, as appointed books in most of disciplines. Electronic books (e-books) have not found the same favour. The potential of e-books to support learning activity has been acknowledged, and new services have emerged in recent years, but uptake has been slow.

Abstract

Aquaculture is facing the serious effects of climate change in the form of scarcity of water and shift in dissolved oxygen level leading to outbreak of diseases. In a study conducted in Farm facilities of ICAR, Tripura it was seen that rise in temperature do have significant effect on hematological and biochemical parameters of fish which are basic index of good health of any organism. Many different diseases occur in the farmers’ pond and which can be controlled. So some basic diseases and their controlling strategies have been pointed out that can lead to better management of fish diseases in pond condition.

In literal sense a species is called underutilized whose potential has not been properly realized. These underutilized crops (referred to also by other terms such as minor, orphan, neglected, underutilized, underexploited, underdeveloped, lost, new, novel, promising, alternative, local, traditional, niche crops) have been included in world-wide plans of action after having successfully raised the interest of decision makers. Wealth of plant genetic diversity currently available holds vast potential. We use only small number of crop plants for our basic requirements. Many thousands of wild plants have great economic and cultural importance and tremendous market potential for vast numbers of people throughout the world. But the majority are still unknown to science. Plant genetic resources have gained global attention in  recent past by agricultural and environmental institutions. Conservation and use of genetic resources attracted  considerable attention. Value of biological diversity in economic terms is very important for human society.

12.1. General Practices for Storage

• Lime juice is mixed with grains and then sun dried before storage to prevent insect pests (Farmers in Nigeria).
• Seeds are safely stored in earthern pots after mixing with the leaves of neem and Vitex negundo (Farmers in Gujarat, India).
• Drying seeds and grains of all the crops on the new moon day before storing to avoid pest attack.
• Store seed materials in earthen pots which are kept on the ‘Paran’ directly above the furnace in kitchen. The smoke acts as a repellent.
• Grains, trees etc. harvested on full moon day are raqre prone to storage pest attack.
• Mixing the dried leaves of neem with seeds while storing them.

Introduction

The better quality of life for the Indians who in majority depend on agricultural would be impossible by keeping the rich tradition of Indigenous Technical Knowledge (ITK) aside (Das, et al., 2002). According to Farrington and Martin (1988), ITK is based on knowledge, beliefs and customs which are internally consistent and logical to those holding them but at odds with the objectively deduced findings of formal science”. Indigenous Technical Knowledge (ITK) is the knowledge that the indigenous and local community accumulates over generations of living in local environment. It encompasses all forms of knowledge, experience, technologies, know-how, skills, beliefs and practices. These are also termed as “indigenous knowledge”, “people’s knowledge” “traditional knowledge” or “local knowledge” and are limited within a community. It is unique to a given culture, location or society.

Fishermen all over the world use some kind of traditional knowledge. ITK provides valuable insight into sustainable aquaculture, because it passes through considerable adaptation, up gradation and modification over a period of time and carried on from one generation to another as a family technology. Naturally, ITK fits well to a particular environment rather than modern technological knowledge. This knowledge has been developed outside the formal education system and refers to the large body of knowledge and skills which includes variety of fish culture practices, when and where to catch, how to process fish with a cost effective methods, and how to maintain their environment in a state of equilibrium. ITK is collective in nature and is often considered the property of the entire community, and does not belong to any single individual within the community.

1.1 Classification

The raw or ungrouped data are in unorganized form and need be organized in meaningful and readily comprehensible form in order to facilitate further statistical analysis. Classification of data is the first step in this direction. It is the process of arranging thing in groups according to their resemblance and affinities. There are two basic types of classification namely-qualitative and quantitative. In qualitative classification, the basis of classification is some attribute or quality like: sex, literacy, religion, etc. A qualitative classification may be simple or manifold. The classification done with respect to one attribute is termed as ‘Simple Classification’. The classification in which two or more attributes are considered and several classes are formed is called ‘Manifold Classification’. In quantitative classification, the collected data are grouped in respect of characteristics, which can be measured and numerically expressed such as height, weight, etc.

Introduction

Manures are obtained from the plant residues, green manure, compost and animal wastes that are used as source of plant nutrients. They release nutrients after their decomposition. They essentially function as sustenance to the crops. They help in the proper cultivation of crops. The addition of manure enables the soil to hold more water. Organic manures have acids that dissolve the nutrients in the soil and make them available to the plants. manures can be grouped into bulky organic manures and concentrated organic manures. Brief dissection about manure given blow flow chart.

Bulky Organic Manure

Bulky organic manures are those materials of plant and animal origin, which contain small percentage of nutrients when added to the soil have tendency to decrease bulk density and to increase soil volume, thus providing better physical conditions for plant growth especially in coarse textured soils and also provide essential nutrients in smaller quantities than the chemical fertilizers. Characteristics of bulky organic manures:

INTRODUCTION

Wheeler bearers commonly referred to as ‘Rotifers ‘are significantly they are often taken as reliable indicators of mesotrophic characteristics in the lake ecosystems (Gannon and Stemberger, 1978). Because of their wide tolerances to varied dissolved oxygen levels and temperature distributions, they are even found to inhabit the deeper waters of aquatic ecosystems (Esparcia et al., 1989). They belong to the Kingdom Animalia, Subkingdom Eumetazoa, Phylum Rotifera (Cuvier, 1798) having three classes Monogononta, Digononta and Seisonidea (Pennak 1953). In other words these wheel animalcules named, because of the presence of their corona, which is composed of several ciliated tufts around their mouth region. This ciliated tuft helps in locomotion and resembles a wheel. These create a current that sweeps food into the mouth, where it is chewed up by a characteristic pharynx (called the mastax) containing a tiny, calcified, jaw-like structure called the trophi. The cilia functions to pull the animal, when unattached, through the water. Most free-living forms have pair of posterior toes to anchor themselves while feeding. Rotifers are bilaterally symmetrical found in various shapes. There is a well-developed cuticle, thick and rigid, providing a box-like shape, or flexible, giving the animal a worm like shape; such rotifers are respectively called loricate and illoricate.

Habitats of Rotifers are relatively easy to find. Many live in ponds, moist soil, or any stagnant water. Rotifers can be free swimming or sessile. Rotifers are mostly omnivorous and some have been observed to be cannibalistic. They normally eat algae or decomposing organic material. As they are a major food source for Cladoceran , Copepodans , juvenile fishes (fry) and fishes, therefore , an important food link of water ecosystem (Arora and Mehra 2003). Presence of abundant Rotifers in freshwaters determines them to be one of the main groups of zooplankton in limnological studies. They are permanently and obligatorily connected to aquatic habitats in all active stages and only their resting stages are drought-resistant (Chopra et al 2012). Various researchers have conducted pioneer study on the diversity and habitat of rotifers such as Anderson 1889; Sharma 1987; Sharma 1998a; Gilbert and Schreiber 1998; Arora and Mehra 2003; George et al. 2011; Tyor and Chawala 2012. However such studies on Madhuganga dam water has not been conducted, hence for assessment of Madhuganga Lentic water has been conducted for the seasonal variation in diversity and density of rotifers.
