Trees have been used in cropping systems since the beginning of agriculture. Throughout the world, at one period or another in its history, it has been the practice to cultivate tree species and agricultural crops in intimate combination. In the tropics, human beings underwent a transition from hunting/gathering to the use of domesticated plants and livestock. As a part of the process they cut down trees, cleared the debris by burning and sowed crops in the ash- enriched soil. It was the ‘slash-and-burn’ agriculture, a primary forerunner of the present day agroforestry and a practice that might have originated in the Neolithic period, around 7000 BC.

There are innumerable examples of traditional land-use practices involving combined production of trees and agricultural species on the same piece of land in many parts of the world. Trees were an integral part of these farming systems and they were deliberately retained on farmlands to support agriculture. These practices are now known as agroforestry. However, the ultimate objective of these practices was not tree production but food production.

Introduction

The world’s food and nutritional security are under serious threat from climate change. Climate changes have significant effects on agriculture by affecting insect pests, their natural enemies, and pollinators as illustrated in Fig 1 (Eigenbrode and Adhikari, 2023). According to Benedict (2003), 13.6% of annual crop loss worldwide is attributed to insect pest attack. Crops, crop pests, natural enemies and pollinators are directly and indirectly impacted by erratic climate. The continuous and anticipated alterations in these insects vary across species, systems, and geographical areas, impeding the development of strong generalizations and forecasts. Moreover, the implementation of “climate-smart” agricultural methods, may have additional effects on ideal management of these insects.

Direct effects on insect pests

Temperature: The most reliable, well-researched, and easily modelled component of climate change is warming. Warming affects physiology, phenology, dispersal, reproduction, development, and survival of insect pests (Bale et al., 2002) as illustrated in Fig 2 (Skendži? et al., 2021). It can be inferred that increased herbivory would be associated with rising temperatures in many cases. High temperature and high humidity are key reasons for whitefly population increase (Pathania et al., 2020). Warming can alter the number of insect generations in Helicoverpa armigera (Lepidoptera: Noctuidae) in China (Huang and Hao, 2020).

ABSTRACT

The use of Geographic information system to locate groundwater possible zone in Valapadi taluk of Salem was carried out using remote sensing and geophysical studies. The remote sensing methods involved in the visual interpretation of the satellite images for hydrogeomorphological and hydro structures favourable for groundwater. The geophysical method involved vertical electrical soundings to predict the sub-surface variation and to locate the water domain. Three geoelectric layers were delineated from the interpretation of vertical electrical sounding data and the map of the above results predict the depth extent of groundwater zone. The spatial distribution of the above results was identified through GIS.

Introduction

Agriculture is the mainstay of the Indian population and contributes about 30 per cent to the gross domestic product of India. The government has laid great emphasis onimproving productivity, quality of produce and welfare of farmers through awareness campaign and enhanced agri-knowledge for the farming community to double the farmer’s income by 2022 and make the farmers realise their significant contribution to the nation building. Doubling the farmer’s income can only be possible, with proper diversification of crops, developing the existing irrigation system in proper utilization of available water on plant requirement basis, conservation of soil fertility through adding organic manures to the field, best utilization of human excreta from the storage tanks of individual toilets after proper decomposition through bacterial degradation, fulfilling the nutrient requirement of crops on the basis of soil test values, proper financial support from the Government to the farmers in managing stress due to natural calamities etc. The governmentbelieves that farmers’ welfare will improve if there is increase in net income from the farms. With this end in view, the approach is to reduce cost of cultivation, enable higher yield per unit area and realize remunerative prices of farm produce. To achieve this goal, action on three pillars needs to be taken.

Introduction

The thermal performance of a building refers to the process of modeling the energy transfer between a building and its surroundings. For a conditioned building, it estimates the heating and cooling load and hence, the sizing and selection of HVAC equipment can be correctly made. For a non-conditioned building, it calculates temperature variation inside the building over a specified time and helps one to estimate the duration of uncomfortable periods. These quantifications enable one to determine the effectiveness of the design of a building and help in evolving improved designs for realizing energy efficient buildings with comfortable indoor conditions. The lack of proper quantification is one of the reasons why passive solar architecture is not popular among architects. Clients would like to know how much energy might be saved, or the temperature reduced to justify any additional expense or design change. Architects too need to know the relative performance of buildings to choose a suitable alternative. Thus, knowledge of the methods of estimating the performance of buildings is essential to the design of passive solar buildings.

Cabbage

Genetic Resources

Historical evidences indicates that modern hard-headed cabbage cultivars are descended from wild non-heading Brassica originating in the Eastern Mediterranean and in Asia Minor. The ancient Greeks held these early forms of cabbage in high regard and believed that they were a gift from the God. The Clelts and, the Romans disseminated cabbage throughout Europe. In fact, the Latin name Brassica is derived from the Celtic word bresi meaning cabbage. Over a period of centuries, hard-headed cabbage types evolved in northern Europe, while loose-heading, heat resistant types developed further in South. Cabbage was first introduced USA when the French explorer Jacques Cartier planted seed in Canada on his voyage in 1541. Cabbage is grown for the thickened main bud called head. The Portuguese introduced cabbage much earlier than cauliflower. There are reports that it was also grown during the Mughal period. In India, much varieties of cabbage are not available. However, genetic resources of cabbage for high yield and resistance to biotic stress are given in Table1.

Drought is a complex and multifaceted issue that affects various aspects of the environment, economy, and society. Its far-reaching consequences underscore the need for a comprehensive and collective approach to mitigate its impacts. 2.1 Drought Prone Area Delineation Drought-prone area delineation involves using scientific criteria like low and erratic rainfall, groundwater potential and agricultural indicators to identify regions susceptible to drought. Modern methods use GIS (Geographic Information Systems) to integrate data from satellite imagery, weather patterns, soil conditions, and vegetation to precisely map drought-vulnerable zones. This spatial analysis allows for targeted interventions such as improved water management techniques and sustainable agricultural practices in the most affected areas. Here are some additional details on the universal nature of drought and the benefits of a global response:

Phytophthora infestans

• Phytophthora in Greek means “plant destroyer”(phyto=plant, phthora= destroyer).

The 21st century has ushered in an era of unprecedented drought challenges, with far-reaching implications for global ecosystems, economies, and human societies. The increased frequency, severity, and duration of droughts worldwide have pushed water resources, agricultural systems, and communities to the brink, underscoring the pressing need for comprehensive understanding and proactive management. • One of the most striking aspects of modern droughts is their capacity to affect vast geographic areas, transcending national borders and impacting multiple sectors simultaneously. The 2012 drought in the United States, for instance, affected over 80% of the country, leading to significant economic losses in agriculture and beyond. Similarly, the 2018 Cape Town water crisis brought the city to the edge of “Day Zero,” where the taps would run dry, highlighting the devastating potential of droughts on urban water systems. • The impacts of droug

Economic analysis provides a rational basis for making decisions in allocating scarce resources among various options to achieve competing goals. If resources were not limiting, there would be no need for economic consideration.

PRINCIPLES OF ECONOMIC ANALYSIS

Optimization criteria

The additional return obtained from using one additional unit of an input should be considered to optimize net income from several possible production options. If option ‘x’ gives a higher return to land than other options, then additional units of land should be allocated to option ‘x’.

Introduction

Pomegranate is one of the most remunerative fruit crops that grow well under arid and semi-arid agro eco-system with severe scarcity of water. The popularity of pomegranate has grown tremendously due to its health beneûts, high returns on investment, less water requirement, therapeutic and functional properties. Growing health consciousness among the consumers and acquisition of super fruit status by pomegranate has made marketing of pomegranate fruits and derived value added products quite easy. As the result of all these benefits, India is witnessing a pomegranate revolution with more than 80 % expansion in area and 250 % increase in production during last one decade. However, there are many challenges to be overcome so as to double the income of pomegranate growers, these challenges include market glut due to unprecedented increase in production coupled with limited export resulting into suboptimal price of the harvested produce; intensification of diseases and insects and pest due to huge unplanned expansion; dominance of only one variety; very limited value addition; hampered export due to suboptimal quality, unwanted sprays, issue of pesticide residues and lack of sufficient number pesticide label claims in pomegranate; inadequate supply chain management. So, in order to overcome these challenges and to increase the profitability of pomegranate stakeholders, we need to focus on scientifically sound cultivation practices to reduce the cost of cultivation, breeding for improved varieties, improved packaging, transport, storage, marketing, supply chain management, facilitating and encouraging export, practicing and promoting climate resilient horticulture, formation of farmers’ cooperatives and farmers producers organization (FPOs), processing and value addition with the aim of total utilization and use of information and communication technologies. This article deals with opportunities and strategies in pomegranate for doubling farmers’ income through nursery management; improved horticultural practices; integrated disease, insets pests and nutrient management; use of information and communication technologies; creation of FPOs; processing and value addition.

INTRODUCTION

Intellectual Property Right (IPR) is described as a generic legal term for patents, copyrights, and trademarks, making the feasibility for legal rights to protect ideas, the expression of ideas, and the inventors and creators of such ideas (Brown, 2003). Two types of rights, first, associated with patents and second, associated with copyrights are included into the current IPR regimes. The social purpose behind the IPR is to reward the originator of an invention. Intellectual property serves as a strong foundation of the modern information economy since it promotes software, life sciences, and computer industries, and has becomes a part of most of the products we consume today (Gallini and Scotchmer, 2002).

The genetics is the study of inheritance and variability of organisms. Bacterial genetics is a sub-field which specifically studies transmission of genetic information from one bacterium to its progeny or between the interbreeding bacteria and the expression of genetic information.

Mutation

Hugo de Vries (1848-1935, Dutch botanist) coined the term ‘mutation’. It is originated from a Latin word which means ‘to change’. The heritable change in bacterial DNA sequences is known as bacterial mutation. The mutation will generate a new type of bacteria with altered genotypical and phenotypical characteristics, known as ‘mutant’. The parent bacterial cell from which the mutants are generated is known as ‘wild type’. In nature bacterial mutation is a rare incidence. The spontaneous mutation occurs at a rate of 1 in 10⁵ to 10⁸. The phenotypical expression of mutation occurs quickly as the bacteria are haploid with shorter generation time.

Major pests

The major pests of coconut include the rhinoceros beetle, red palm weevil, black headed caterpillar, root grub and the perianth mite.

Abstract

In order to fill the gap between the protein sequences and their 3D structures available in the public databases, the computational prediction of protein structure has become the need of the hour. Therefore, the present chapter aims to highlight various methods and strategies for computational protein structure prediction by established ab initio, threading and homology modeling methods. Ab initio, threading and homology modeling methods are mainly based on the low sequence similarity, similarity between 25-30% and similarity more than 30% with the template structure respectively. Hybrid methods are preferred which club together a number of features such as structural alignments, solvent accessibility and secondary structure informations.

Abstract

The social and economic development of any state is interlaced with the manner of its natural resource management. The unplanned use and overexploitation of resources are results in various kinds of land degradation, biomass deterioration and siltation of tanks. In addition, the low per capita availability of land, erratic and uneven distribution of rains, undulating topography, improper management, traditional cropping programmes and recurrence of droughts having cumulative effect leading to low productivity and high risk particularly in dryland farming. Further, developing dry land agriculture through sectoral approach did not bring in the desired results, as the efforts were not integrated. However, in nature all the resources are inter-linked and thus, the integrated developmental approach is the best solution for optimal development of any area. Further, development based on administrative units such as district, taluk, block and village have resulted in imbalance and sometimes, no overall development in some areas. Considering this, natural resources management through Geo- informatics tools like, remote sensing, GIS, GPS and other sensor based techniques are the possible ways for making agriculture sustainable. The paper mainly highlights theimportance of application of latest technologies in agriculture along with some field level case studies.

Introduction

The rose is one of the oldest flower in cultivation and rank 1^st position worldwide as cut flower. There are two types of roses; first stemless rose supplied by field grown roses for making garlands or extraction of rose oil or rose water. Second is stemmed rose, which is mainly grown under protected conditions for cut flower production used for making bouquets or interior decoration.

The cultivation of this flower has developed with the distillation of rose as mentioned in Ayurveda by Charaka around 100 A.D. At present, it has become the most important commercial flower. A large quantity of rose flowers is used for decoration purpose.

Apple is a king of temperate fruit, symbol of health and premier fruit of the world. It is a deciduous temperate fruit tree and most widely grown in the world from time immemorial. In India, a large number of apple varieties were introduced in 1887 by Mr. Alexander Coutts, and his orchard is called Hillock Head in Mashobra near to Shimla. It was also introduced in Nilgoris and Bangalore, but it was destroyed by wooly aphid in 1887. At present a small cultivation is done in Nilgiris. Among the fruits, apple is having longest storage life. Apples are mostly consumed as fresh but a small part of the production is processed into juices, jellies, canned slices, wine and other products.

Origin and Distribution

An apple is originated in the Middle East/Central Asia more than 4000 years ago where its wild ancestor, Malus sieversii, is still found today. It is spreading across Europe to France; the fruit arrived in England during the time of Norman Conquest in 1066. The pioneer apple orchard in the North American continent was planted in Boston by Reverend William Blaxton in 1625. The Only North America native apples are called crab apples or common apples.

Captain R C Scot of the British army had introduced apples like Newton Pippin, King of Pippin and the Cox Orange Pippin to the Kullu valley in 1870. These apples were not popular because of their sour taste. The sweet apples were still being imported from Japan to meet the demand of Indian market. It was during a visit to America in 1915 that Samuel Stokes bought a few saplings and planted them at his Barobagh orchard in Thanedar and in the year 1926 the first apple trees bear fruit and the apples was sold and imports from Japan is stopped. The first few saplings from its, Golden Delicious of Kinnaur and Sweet Delicious of Shimla were became popular and Himachal Pradesh grew to become one of the largest producers of the fruit today. Therefore, the Himachal Pradesh is known as apple bowl of India.
