3.1 Chemistry of greenhouse gases (ghgs)

Greenhouse gases (GHGs) are atmospheric-gases that have capabilities to absorb and radiate-back the infrared (IR) radiation in the earth-atmosphere system (Figure 3.1). In this process the atmospheric-gases absorb and radiate- back IR radiation in lower atmosphere effectively emitting and absorbing heat energy heat energy. They maintain the heat budget of earth-atmosphere and keep our plant warm. If we typically see the chemistry of those gases, the key point is that they should have dipole moments. This is the property which makes them capable to absorb and radiate-back the range of IR radiation. In a molecule when valence-electrons are not equally shared in a bond between the two atoms, a slight positive charge is developed above one atom and a negative charge on the other atom. That charge difference of the different atoms in a molecule generates the dipole moment. For instance, in water vapour (H₂O- vapour), an unequal sharing of electrons and or separation of charge causes dipole moment. In H₂O, the centre has a positive charge at the hydrogen atoms and negative charges are located on the oxygen atom. The magnitude of dipole- charges, vibration and stretching of O-H bond generates certain frequency of the oscillating dipole moment that actually regulates the absorption capacity of IR radiation by H₂O vapour.

Accurate estimation of embryonic/foetal age play vital role in the developmental anatomy research related to morphogenesis and histogenesis of an organ or system. The observations and recordings of normal developmental features of embryos/ foetuses at successive stages of gestationare very important for studying functional development of an organ in anatomical research. The documentation of normal embryonic and fetal growth can serve as a guide for understanding the consequences of harmful influences at various stages of gestation (Evans and Sack, 1973). Post-mortem studies have provided valuable information on fetal development, identifying stages such as implantation, appearance of forelimb bud, tail development and hind limb development (Alberto et al., 2013). The normal development of external features of animals has been described by Evans and sack (1973), however, subjective assessment of foetal age from the external features alone is not much reliable, although it may be useful adjunct to more precise measurements (Richardson et al., 1990). For accurate estimation of developmental age, fetal measurements are needed which show a consistently rapid rate of growth and which are least variable at a given age (Richardson et al., 1990), however, these parameters are affected by individual variation and by breed differences within a species (Greenwood et al., 2005).
A number of methods have been discussed by many workers for estimation of age of foetus in animals. The method mainly focus on foetal biometry recorded either inside uterus during normal gestation process or after taking out foetus during post-mortem examination. In-utero foetal biometry allows estimating gestational age and time of parturition by ultrasonographic methods (Manning

1. Introduction

With the fairly recent advent of inexpensive, rapid sequencing technologies that continue to improve sequencing efficiency and accuracy, many species of animals, plants, and microbes have annotated genomic information publicly available. It is important to use this genomic information for the identification and isolation of novel and superior alleles of important genes from gene pools of the organisms

13.1. INTRODUCTION

Pearl millet crop has a wide adaptability to local environments. It is hardy and can be grown in areas which are very hot and dry and on soils too poor for sorghum. Pearl millet is considered more efficient in utilization of soil moisture and has a higher level of heat tolerance than even sorghum and maize. It is adapted to warm and dry climate but most of the area under the crop is in drought- prone areas of the world. In these areas, pearl millet is usually grown with limited inputs, sparse rainfall, low soil fertility, and also face disease and pest problems, with correspondingly poor yields.
 
The low average yields are primarily a result of the hot, dry conditions where pearl millet is mostly grown, rather than pearl millet plant’s capability. Pearl millet hybrids grown under better conditions yield 3000 to 4000 kg/ha compared to 300 to 800 kg/ha when moisture and soil fertility become limiting factors. A majority of the subsistence farmers who typically cultivate this crop are unable to take advantage of high yield potential because they have limited options for improving their management practices. Pearl millet production can be increased through growing varieties/hybrids with improved tolerance to drought, diseases and responding to higher rates of fertilizer applications.

Introduction

The rapid growth and socio-economic upliftment of a developing country are directly related to the intensity of industrial growth of that country (Bastian et al., 2019; Kniivila, n.d). The emergence of new enterprises is the main source of a healthy and growing industrial ecosystem. They represent 99% of businesses in developing countries and account for two-thirds of employment creation (Secretary-General and UNCTAD, 2022). Enterprises hence create employment, drive inclusive growth, promote innovation, and improve socio cultural conditions along with addressing sustainable development goals- No poverty(SDG-1), Industry, innovation and infrastructure(SDG-9), Reduce inequality(SDG-10)of the UN’s 2030 agenda (Forbes, 2022; Secretary-General and UNCTAD, 2022). Their innovative outputs in the form of goods and services, address local as well as global requirements of the customer market and bring them on the path of sustainability (Szopik-Depczynska et al.,2018; Rivera et al.,2020). The entrepreneurs have a long vision of success, engaging their primary activities with No poverty (SDG-1), Zero hunger(SDG-2), Gender equality(SDGs-5), Decent work and economic growth(SDG-8), Industry, innovation and infrastructure(SDG-9), Reduce inequality(SDG-10), Responsible consumption and production(SDG-12), Climate action(SDG-13), Partnership for goals(SDG-17) and addressing challenges of society and the environment in return for optimal economic profit (Alagpuria,2021; Lammers et al.,2022; Secretary-General and UNCTAD,2022; Vig,2021; Del-Aguila Arcentales et al.,2022; Sadiq et al.,2022).

About Mendel

Born in what is now the Czeck Republic.

Grew up in an agricultural environment.

Became a priest-teacher at a local monastery.

Took courses in botany, physics, and mathematics at the University of Vienna.

Gregor Mendel was the first person to comprehend some of the most basic principles of genetics. He reached these understandings in the mid-nineteenth century; working in what is now the Czech Republic and using as his experimental subjects a species of garden pea, Pisum sativum..

Carried out “hybridization” experiments with the common garden pea.

Mendel’s hypotheses became the laws of inheritance in modern genetics.

Mendel’s work re-discovered by Correns, DeVries, and Tschermak in 1900. Period of modern “Mendelian” genetics begin.

Reproductive development determines flowering, pollination, fruit set, fruit growth, maturation, and ultimately horticultural productivity. This chapter introduces the physiological processes controlling flowering and reproductive development and explains the influence of environmental factors and plant hormones. Major plant growth regulators such as auxins, gibberellins, cytokinins, ethylene, and abscisic acid are considered in relation to horticultural applications. PGRs can influence rooting, flowering, fruit set, fruit size, thinning, ripening, dormancy, and senescence when used appropriately. The chapter emphasizes crop-specific concentration, timing, method of application, and environmental conditions, highlighting the importance of responsible PGR use for improving yield, quality, and marketability.

There is no better engineering than life.

What is life - is a perennial question. Life is defined in different ways depending upon who is defining it. Biologists define life using a list of characteristics, such as metabolism, evolution, homeostasis, constant transformation, genetic information, etc. Life has been defined as self-maintaining and self-producing systems. Physicist Erwin Schrödinger (1), argued that living organisms escape the destiny of disordered equilibrium because they are able to take up ‘orderliness’ from their environment. Philosophers have defined life from different angles. They say that life can only be understood fully from an ‘insider’ perspective.

Life is not a random collection of extinct molecules. It is a process of dynamic renewal; everything in life is constantly turning over and renewed. Life exists in diverse forms. Each form is specialised to survive and reproduce in its particular niche.

One understands life from one’s own perspective. For some, life is an ‘objects in flux’ that constantly exchanges matter with the environment. It is systematic material exchange into an organized body. Then there is a view that says that all living organisms deserve moral consideration. All living organisms, however, do not have equal moral significance; vertebrates, for various reasons, deserve more moral consideration than would bacteria or plants. Then there are myriad religious ways to define life. The simplest is “God created the world and all living organisms.” No further questions, accept or reject the hypothesis.

Abstract

High precision Geodetic Global Positioning System measurements have become important for studying present-day tectonics in active orogenic belts such as the Himalayas. Geodetic Global Positioning System measurements in the Darjiling-Sikkim Himalayas (DSH) during 2000-2004 indicate that the frontal part of the Darjiling Himalaya is locked to the Indian plate and statistically negligible shortening is accumulating there at present. While this observation is in conformity with observations made in Nepal to the west of the DSH, it differs in the fact that about ~ 12 mm/yr of convergence is accommodated in the DSH and the western Bhutan Himalayas as opposed to about ~ 20 mm/yr in Nepal Himalaya. About 16 mm of convergence is accommodated in the Arunachal Himalaya, to the east of DSH, of which about 6 mm is accommodated in the Lesser Arunachal Himalaya. These observations indicate that there is a fair amount of heterogeneity in the way convergence is accommodated along the length of the Himalayan arc and the Himalayan seismic hazard estimations need to account for this. Seismicity patterns in the DSH indicate that active deformation in the area is driven by strike-slip as well as thrust tectonics. Strain accumulation in the DSH during 2000-2004 appears to be dominated by strike-slip tectonics in the region and about ~ 4-5 mm/yr of sinistral strike-slip is observed along a NNE-SSW trending near-vertical fault identified in the area (named as the Gish transverse fault).

Linkage and Crossing Over

Crossing over may produce recombinant phenotypes.

Bateson and Punnett discovered two traits that did not assort independently.

Morgan provided evidence for the linkage of several X-linked genes and proposed that crossing over between X chromosomes can occur.

A chi square analysis can be used to distinguish between linkage and independent assortment.

Creighton and McClintock correlated crossing over that produced new combinations of alleles with the exchange of homologous chromosomes.

Crossing over occasionally occurs during mitosis. Genetic Mapping in Plants and Animals

The frequency of recombination between two genes can be correlated with their map distance along a chromosome

Alfred Sturtevant used the frequency of crossing over in dihybrid crosses to produce the first genetic map.

Trihybrid crosses can be used to determine the order and distance between linked genes.

Interference can influence the number of double crossovers that occur in a short region.

Globally, organic oilseeds constitute an important element in organic production. Their products are important feedstuffs (oilcake) and also relevant for human consumption (soya products, oils), and demand for these is continually growing. Almost half of the global organic oilseed area is occupied by soybeans, and another almost 20% is for sunflower seeds and sesame. Rape and turnip rape constitute about 6% of the organic oilseed area. Oilseeds are of pivotal significance in the Indian agricultural economy supporting income of millions of farmers practicing mainly rainfed cultivation. Nine annual oilseed crops are cultivated in India that includes groundnut, rapeseed-mustard, soybean, sunflower, sesame, niger and safflower that are edible and non-edible oilseed crops include castor and linseed. Organic agriculture is one among the broad spectrum of production methods that are supportive of the environment. The principal method of organic farming includes crop rotation, green manures and composts, biological pest control and reduced tillage. The performance of annual edible oilseed crops and development of package in relation to organic management for sustainable agriculture are discussed in this chapter.

1. Introduction

In India, both annual and perennial edible oilseed crops are cultivated. Annual edible oilseed crops include groundnut, rapeseed-mustard, soybean, sunflower, sesame, niger and safflower. India, the 4th largest vegetable oil economy in the world, stands first in the production of castor, sesame, safflower, and niger oils, whereas second in groundnut, third in rapeseed mustard, fourth in linseed and fifth in soybean oil. About 14 million farmers are engaged in oilseeds production and another million in their processing. Whereas, the perennial edible oil seed crops include oil palm and coconut. Edible oils are also produced domestically from secondary sources such as rice bran, cotton seed, corn, and other tree-borne oilseeds (TBOs), besides some minor oil producing species of forest origin.

Abstract

This paper presents a kinematic analysis for explaining the spatial and temporal variations of deformational structures in the Cuddapah Proterozoic orogenic belt, South India. This belt shows virtually undeformed, flat-lying sedimentary rocks in its western margin, whereas strongly deformed and folded rocks in the eastern boundary. The structural variations indicate increasing deformation in the east direction, implying a relative tectonic convergence from the east side. Based on the corner flow theory, we use a viscous model to determine the heterogeneous strain field in the asymmetric convergent zone, and explain varying deformations from the foreland to hinterland. According to this model, the strain field in the hinterland part varies in a pulsating manner with progressive crustal thickening, giving rise to multiple deformational structures in the course of a single continuous tectonic movement. We also studied the strain field in finite element models considering the gravity forces, and obtained similar results. The foreland vergence of deformational structures in the Cuddapah belt indicates a top-to-west horizontal shear during the overall horizontal contraction. Our numerical models show that this horizontal shear component in the foreland region is likely to be associated with a vertical shear component in the hinterland.

4.1 Agroeconomic Features of Manipur in Brief
Nestled in the North-Eastern region of the India sub-continent, Manipur is a beautiful state located between 23°81’ N to 25°68’N latitude and 93°03’E to 94°75’E longitude an area of 22,327 sq. km. and sharing an international boundary with Myanmar in the East which also lies to its south along with Mizoram. It is bounded by the Cachar District of Assam in the West and to its North lies Nagaland.
Physio-graphically, Manipur is one of the most enchanting place in the country. It can be broadly classified into three well defined geographical region viz. the hilly region, the central plain or the Manipur valley and the Jiribam plain. The hilly region of Manipur covers about 90% of the total land area of the state. It stretches mainly from North to South or North-South parallel folds with an altitude varying altitude of 833m to 3030m above MSL. The Manipur valley is situated in the central part in Manipur covering an area of 1843km2 which account for about 9% of total land area of the state having an oval shaped elevated plain surrounded by hilly on all sides and extended about 58 km from North to South and 31 km from East to West. The central valley has an elevation ranging between 700 m and 800 m above MSL. About 70% of the total population of the state resided in the central plain of Manipur. The whole valley slopes from North to South. The Jiribam plain lies beyond the Manipur Western hill tract covering an area of 1% of the land area. The central valley along with the Jiribam valley situated at a lower altitude of 400 m in the southwest part of the state outside the western hill ranges of Manipur occupies 11.72 percent of the total geographical area of the state. The rest of the state is hilly. Manipur is endowed with a wide range of climatic, physiographic and geological conditions resulting in the formation of different kinds of soils.
4.2 Climate
The impact of terrain diversity, altitudinal variation and river regime has become eloquent in the seasonal variability of climate from one place to another. The Barak basin and lower foothills of Manipur Western hills have

Introduction

Biosensor technology is a powerful alternative to conventional analytical techniques, harnessing the specificity and sensitivity of biological systems in small, low cost devices. Despite the promising biosensors developed in research laboratories, there are not many reports of applications in agricultural monitoring. The authors review biosensor technology and discuss the different bio-receptor systems and methods of transduction. The difference between a biosensor and a truly integrated biosensor system are defined and the main reasons for the slow technology transfer of biosensors to the market place are reported. Biosensor research and development has been directed mainly towards health care, environmental applications and the food industry. The most commercially important application is the hand-held glucose meter used by diabetics. The agricultural / veterinary testing market has seen a number of diagnostic tests but no true biosensor systems have made an impact.

Climate change presents horticulture with increasing challenges including heat stress, water scarcity, erratic rainfall, extreme weather, new pest pressures, and changing crop suitability. This chapter examines strategies for developing climate-resilient horticultural systems through improved cultivars, efficient irrigation, protected cultivation, mulching, canopy management, soil-health practices, and diversification. Climate-smart production also requires better forecasting, monitoring, risk management, and resource efficiency. Future horticulture is expected to integrate biotechnology, artificial intelligence, precision agriculture, automation, renewable energy, and resilient production systems. The chapter emphasizes adaptation rather than dependence on a single technology, promoting integrated approaches that maintain productivity, quality, profitability, and ecological sustainability under changing climatic conditions.

A successful and sustainable farmer producer organization (FPO) is an entity that is owned and managed by farmers, and is focused on improving their livelihoods through sustainable and profitable agricultural practices. Such an organization operates with a long-term vision, and is able to adapt to changing circumstances in the agricultural sector. Viability, stability and sustainability are the three degrees of permanency in business. Analysis of these three is very important for any business and entrepreneurs.

5.1. Viability

viability of a business indicates that it is (or has the chance to be) successful. A viable firm is profitable, which indicates that it generates more income than it spends on operating expenses. It is tough to resurrect a failing firm. The company would need to either boost income or lower expenditures. 

Sustainable horticulture seeks to produce nutritious and economically valuable crops while conserving soil, water, biodiversity, and other natural resources. This chapter examines organic, natural, and broader sustainable production systems and their underlying principles. Topics include organic inputs, compost, biofertilizers, biological pest management, crop diversification, mulching, recycling, soil-health improvement, and reduced dependence on synthetic inputs. Certification systems and market requirements are also considered, including Indian and international organic standards. The chapter distinguishes different production philosophies while emphasizing practical sustainability. Successful systems must maintain productivity, profitability, environmental quality, and consumer confidence. Sustainable horticulture therefore combines ecological principles with sound crop management, market awareness, and responsible resource use
