The livestock sector has emerged as a vital sector for ensuring a more inclusive and sustainable agriculture system. Livestock production can be an important
component of a sustainable agricultural system because it can provide a quality source of plant nutrients, be an income generator, and provide an environmentally
sound use of certain lands. Some farmland is just not suitable for crop production, but may be utilised sustainably for livestock production.

Agroecology : Agroecology can be defined broadly or narrowly. “Loosely defined, agroecology often incorporates ideas about a more environmentally and socially sensitive approach to agriculture, one that focuses not only on production, but also on the ecological sustainability of the productive system.

or

The science of applying ecological concepts and principles to the design and management of sustainable agroecosystems.

Alternative Farming/Alternative Agriculture : These are essentially synonymous terms encompassing a vast array of practices and enterprises, all of which are considered different from prevailing or conventional agricultural activities. “They include:

Modeling phytonematodes is helpful in the investigation of several host plant interactions and may yield useful information to be exploited in the integration of management strategies and biological control. Modeling the phytonematodes density changes in a soil/root microcosm may allow the identification of main factors active in such systems (Ciancio et?al?, 2022). The multiple tri-trophic interactions linking roots, phytonematodes and antagonists, however, originate a very complex system. It requires knowledge about the many parameters describing the nematode life stages, the interactions with the antagonistic organisms present in the microcosm, as well as their capabilities for effective and durable host regulation. Descriptive variables should also account for the effects of roots and of other environmental factors at work in the tri-trophic interaction system. Models may provide benefits, including the possibility of identifying the best moment for the inoculation of a biocontrol agent, the optimal amount of its inoculum applied to maximize its biocontrol efficacy, as well as the possibility to simulate and thus investigate its behavior once introduced in soil.

1. INTRODUCTION

The past hundred and fifty years of this millennium have witnessed an unbelievable pace of scientific and technological development. Modern science has attempted to a great extent and succeeded in realizing the dreams and fantasies of philosophers and scientists of the previous centuries. Plant genetic engineering via., nucleus is a mature technology that has been used productively for research and commercial applications. However, plants have an unassuming second genome inside the tiny organelles called as plastids. Although this small circular DNA carries a fewer genes than its nuclear counterpart, researchers say its potential for genetic engineering far outstrips its size. The ability to introduce foreign genes at specific locations on a chloroplast has been acquired very recently. It is expected that certain limitations of nuclear genome transformation methods in terms of protein expression and environmental safety can be overcome by site-specific introduction of genes into plastids. Thus the plastid engineering forms a viable alternative serving as another milestone in the field of plant biotechnology.

Symbolic systems provide logical reasoning and explicit knowledge representation, whereas sub-symbolic models offer learning, adaptation and pattern-recognition capabilities. This chapter explains how combining these approaches can create more accurate, adaptive and interpretable intelligent systems. It discusses rule-based systems, logic programming, ontologies, neural networks, fuzzy systems, evolutionary computation and swarm intelligence. Neural-symbolic, neuro-fuzzy, rule-augmented and ontology-aware architectures are examined, along with loose, tight and deep integration strategies. Applications in healthcare, cybersecurity, manufacturing and knowledge-based information systems demonstrate their practical potential. Challenges involving integration complexity, scalability, knowledge engineering, transparency and continuous updating are considered, together with future directions in human-centred hybrid intelligence.

Definition and Significance

Garden Components are the garden features that form the expressions of garden, adding charm to the basic garden landscape and constitute its style, contributing strongly to its texture and structure. Thus, garden features are important as they provide face lift to the garden skeleton, giving it a filling effect with charismatic appeal. Garden features include garden wall, fencing, arches, pergolas, hedge-edge, topiary, etc. Creating sudden and unexpected change of scenery sometimes reveal good contrasts. Thoughtful planning of garden features make an invaluable contribution to garden design. It is possible to design a garden with a large number of man-made artistic items. However, indiscriminate and haphazard use of these items results in clutter. Further, new and strange features in the garden always attract visitors and give unbounded pleasure. During ancient time, because of the traditional style of architecture and high craftsmanship, garden features and adornments have played a big role in many famous gardens of the world. Selection of features and positioning of ornaments in a garden are the visible evidence of the owner’s taste of nature and aesthetic sense. Whatever features are chosen, they must add charm, create an atmosphere of naturalistic design and improve the quality of landscape design. Garden features and ornaments are many, but they must be utilized in the design with restraints. Some important garden features are described below.

A levee is an elongated embankment constructed along a river, stream, or floodplain boundary to prevent floodwater from entering protected land. Levees can safeguard settlements, agricultural fields, industries, roads, and public infrastructure, but they do not eliminate flooding and may transfer risk downstream or cause severe damage if overtopped or breached. Their design depends on expected flood level, freeboard, soil properties, seepage conditions, foundation stability, alignment, and available construction materials. This chapter explains levee functions, classifications, advantages, limitations, and structural components. It also addresses seepage control, slope protection, erosion, settlement, failure mechanisms, inspection, maintenance, and the importance of combining levees with forecasting and evacuation planning.

Blood is the fluid pumped by the heart that circulates throughout the body via the arteries, veins, and capillaries . Blood is a body fluid in animals and human beings that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. Hematology is the science or study of blood, blood-forming organs and blood diseases.

Statistical Inference

It is the process of drawing valid inference or conclusion about the population on the basis of a sample drawn from the population. In other words, Statistical inference is the process of using a sample to infer the properties of a population. It requires studies pertaining to three aspects:

• Point Estimation • Interval Estimation

• Testing of Hypothesis • Point Estimation: It is to find a single value, which is used as an estimator of unknown parameter. For example, sample mean may be used as an estimate of the population mean µ.

• Interval Estimation: It is to find confidence limits based on sample values, within which the unknown parameter lies with confidence coefficient described in probability term. In other words, we estimate an unknown parameter using an interval of values that is likely to contain the true value of that parameter and state how confident we are that this interval indeed captures the true value of the parameter.

• Testing of Hypothesis: The tests used to ascertain whether the differences between estimator and the parameter or between two estimators are real or due to chance are called tests of hypothesis or tests of significance. In other words, the procedures, which enable us to decide whether to accept or reject hypothesis, are called tests of hypothesis or tests of significance. Two types of problems mainly arise in tests of significance:

• Testing the significance of the difference between estimator and the pa rameter.

Tomato

Genetic Resources

Tomato, a warm season crop, sensitive to frost, is usually cultivated in sub-tropical and mild cold climates. The National Bureau of Plant Genetic Resources (NBPGR), New Delhi, is the main centre for maintenance of tomato germplasms in India. The Bureau has systematically assembled more than 2,900 germplasms. Some of the promising germplasms identified for different traits on the basis of their morphological variations (Fig.1; see Plate-1) are given in Table1.

Diagnostic biomarkers are measurable biological molecules that provide information about physiological or pathological conditions. This chapter examines the use of metabolomics for discovering, evaluating, and validating biomarkers for disease diagnosis, prognosis, therapeutic monitoring, and personalized medicine. It discusses different types of biomarkers, metabolomic biomarkers, biological samples, analytical platforms, biomarker-discovery workflows, and statistical analysis. Applications in cancer, diabetes, cardiovascular, liver, kidney, neurological, infectious, and metabolic diseases are considered. The chapter also explains the role of metabolomics in drug discovery, toxicology, nutrition, and clinical research. Challenges involving biological variability, analytical reproducibility, data complexity, and clinical validation are addressed alongside future opportunities involving AI and multi-omics.

Modern biological systems cannot be fully understood through a single molecular layer. This chapter examines the integration of genomics, transcriptomics, proteomics, and metabolomics to obtain a comprehensive systems-level understanding of biological processes. It explains the role of each omics discipline and shows how their combined analysis can connect genetic information, gene expression, protein activity, metabolic states, and phenotypic outcomes. The chapter discusses the need for multi-omics integration, computational and network-based analysis, and systems biology workflows. Applications include disease diagnosis, precision medicine, crop improvement, stress tolerance, biotechnology, metabolic engineering, synthetic biology, and environmental research. Multi-omics integration provides improved biological interpretation, biomarker discovery, pathway prediction, and therapeutic target identification.

Boost to crop production has been the ultimate goal of researchers involved in agriculture so as to feed the ever-increasing human and domestic herbivorous animal populations. Crop production is not only constrained by the limited inherent potential of available varieties currently in use, but is also largely affected by the limitations of soil nutrient availability and damages by diseases, insects and weeds. To counter later challenges, augmentation of soil nutrients through use of biofertilizers in integrated nutrient management programmes and restricting the use of chemical pesticide by integrating biopesticides in plant protection programmes has received much attention in recent years because of consumer’s preference for organic food.

INTRODUCTION

Insecticide resistance poses a severe threat to agricultural productivity in India and in other countries of the world. Humans have had the ingenuity to develop thousands of pesticides to protect foodstuffs, livestock, and health and the use of these poisons has triggered a rapid evolutionary response in many target species and some nontarget species of invertebrates, microorganisms, higher plants and vertebrates. Insecticide exposure led to nullify their toxic effects through genetic selection for individuals with the biochemistry or behaviour. Continual development of new compounds and its greater use and increase in input insecticide cost is mainly due increase in resistance. Reduction in insecticide efficacy from insect resistance has major economic, environmental and human health implications. Integrated Pest Management (IPM) is a convenient descriptor for wide range of still-evaluating pest control program that emerged from chemical prophylaxis practiced. IPM theory has fostered a transition from primarily chemical control to programs tempered with biological information and input tailored to each agro ecosystem, crop and pest situation in production.

Soil survey is essentially a study and mapping of soils in their natural environment. It is the systematic examination, description, classification and mapping of soils of an area.

2.1. History of Soil Survey in India

The original investigations on Indian soils were carried out by Voelcker dates back to 1893 and by Leather to 1898.They classified the soils of the country into four major groups, namely the Indo-Gangetic alluvium, the black cotton soil or regur, red soil and laterite soil. Schokalskaya (1932) has published a soil map of India based on the Russian concept which describes 16 soil groups such as climate,vegetation, soil-forming materials, salinity, alkalinity, swamps and peats (Bhattacharyya et al. 2013). In 1935,Wadia and his co-workers collected a soil map of India with significance on geological formations and classified the soils as red, black (regur), laterite and lateritic soils of Peninsular India and also Indo-Gangetic Plains (IGP) which includes delta, desert, bhabar, terai and alkali soils. Vishwanath and Ukil (1943) published a soil map of India by placing the soils in different climatic zones for the first time. This was prepared by Imperial Agricultural Research Institute, New Delhi, and published in the year 1943. There were 17 kinds of soils identified, viz., deep black soils, black clay soils, black loamy soils, black sandy soils, red sandy soils, brown sandy soils, red and yellow soils, dark reddish brown soils, mixed soils (white and yellow), alluvium (Indus, Gangetic, Brahmaputra), coarse alluvium, soils of swamp lands, calcareous soils, usar soils, kallar soils, coastal alluvium soils and soils of Great Himalayan Ranges.

Soil survey works were started in 1954, in most of the states as a part of their agricultural development programme, and Bihar (Soil Survey and Land use Planning Scheme, Sabour) was pioneer. In 1954, the soil survey work was started under the leadership of Dr. P. P. Jha following the conventional procedures in Bihar (including Jharkhand) to delineate the soil associations based on geology, relief, physical and chemical characteristics of soils for the first time in India by the then Soil Survey Scheme at Sabour (Mishra et al. 2001; Mishra 2015, 2016). Meanwhile, the National Atlas Organization, Kolkata, prepared a soil map of India in 1957 classifying Indian soils into six major groups and 11 broad types. Murthy and Pandey (1983) applied the working principles of the USDA 7^th Approximation in classifying the Indian soils with available data on soil classes and thus used the US system for the first time at great soil group level, which was transformed into a soil map of India on 1:6.3 million scale. Mishra et al. (1994) attempted to propose “Fluvisols” as the 13th Order in USDA Soil Taxonomy for active floodplain soils frequently occurring in different parts of India and elsewhere. Mishra (2015, 2016) proposed a framework of Indian system of soil classification mainly based on land use options.

Eventhough nematodes occupy nearly every habitat on earth, they are remarkably similar in morphology and life stages. Despite their structural complexity, certain basic principles are common to all nematodes. Nematodes are triploblastic, bilaterally symmetrical, unsegmented, pseudocoelomate, vermiform and colourless animals. The plant parasitic nematodes are slender, elongate, spindle shaped or fusiform, tapering towards both ends and circular in cross section. The length of the nematodes may very from 0.2 mm (Paratylenchus) to about 11.0 mm (Paralongidorus maximus). Their body width vary from 0.01 to 0.05 mm. In few genera, the females on maturity assume pear shape (Meloidogyne), globular shape (Globodera), reniform (Rotylenchulus reniformis) or saccate (Tylenchulus semipenetrans). The swelling increases the reproductive potential of the organism. Radially symmetric traits (triradiate, tetraradiate and hexaradiate) exist in the anterior region. The regions of intestine, excretory and reproductive systems show tendencies towards asymmetry. The nematodes have one or two tubular gonads which open separately in the female and into the rectum in the male which also have the copulatory spicules.

The free living saprophytic nematodes are generally larger in size. The animal and human parasitic helminths may have length of few centimetres to even a meter or more. The helminth parasitising whale fish is about 27 feet long. The study on these animals and human parasites are known as Helminthology.
