Abstract

Soil Resource Appraisal helps in characterizing the existing land resources, assessing their suitability for various land uses and then helping the user to prepare a rational land use plan suitable for the integrated development of the area. Application of Remote Sensing (RS) and Geographical Information System (GIS) helps not only in the characterization of the resource base, but also in the generation of various thematic maps and preparation of land use and action plans for effective implementation of various developmental plans at farm level.

1.0 Introduction

A thorough knowledge and understanding of soils is basic to the development and management of agricultural resources. About 100 years ago, man began systematic study of soils in the field and tried to separate, classify and map their geographic distri­bution. Today we have sufficient knowledge about soils; however the characterisation, classification and mapping of soils is still tedious, time consuming and costly affair. Therefore the need for adopting new and more rapid and accurate methods of mapping soils has resulted in the use of satellite images with image interpretation techniques for soil survey and map­ping.

In India for the country as a whole, soil and other land resources information is available at 1:1 M scale, which was generated from the state level mapping done at 1:250,000 scale under the Soil Resources Mapping Project of India during the period from 1986 to 1995. This information is of general nature and useful for planning on a wide canvas and not particularly useful for farm or watershed level planning in the country. For site-specific needs and for developmental works at watershed level, we need detailed farm level database at 1:10,000 scale. Once this type of information is generated at village/watershed level, this will be useful for identifying site specific constraints, generation of area and site specific agro technologies, land-use options based on soil site suitability assessment, wasteland identification, identification of prime farm lands and farm clusters for zoning and Strategic planning, preparation of farm level development plans by line departments and proactive advice and technology transfer to farmers.

ABSTRACT

In Tamilnadu majority of the people are engaged in agricultural work and they mainly depend upon the water resources. But at present both surface and subsurface water has become deficient because of over exploitation. Since last few years, conventional methods were employed to improve the surface and subsurface water conditions. But these methods provide less accurate result and consume more time. So to improve the conditions modern tools, such as remote sensing and GIS are being used to identify the ground water potential zones in Tamilnadu. It provides accurate resulst and consumes less time.

A project was carried out in Gadilam lower sub basin which falls in the part of Cuddalore District, Tamilnadu. The IRS 1D imagery was collected and interpreted using image processing software and Geo media GIS Software in conjunction with collateral data to prepare Hydro geomorphology, land use, geology and lineament maps Field checks were made and transferred the field data on the base map. By application of overlay analysis of the above thematic maps, using GIS techniques, the recharge zones were identified.

The satellite image mosaic map of Gadilam lower sub basin was generated to identify ground water potential zones. Average monthly rainfall data for the past 50 years were collected. Using Remote sensing and GIS techniques, the thematic maps such as Geology, Geomorphology, Soil, Drainage, Land use, Lineament zones have been generated for this study. Geophysical survey was also conducted in various locations and the aquifer parameters were measured. Details related to land and water resources, cropping pattern, water levels and water qualities from PWD ground water division, land use and well censes data of villages from village Administrative Officer, tank details from PWD were collected and analyzed

After analyzing the various thematic maps, they were finally overlaid. Thus the groundwater potential zones of Gadilam lower sub basin was identified.

Abstract
Remote sensing and image analysis have emerged as essential tools in modern agriculture, particularly for plant protection in grain-based legume cropping systems. These technologies are increasingly valuable in addressing challenges such as climate change, pest infestations, and the demand for sustainable practices. Grain legumes, including peas, beans, lentils, and chickpeas, are vital for global food security and soil health due to their protein content and nitrogen-fixing capabilities. However, their productivity is often threatened by pests, diseases, and weeds. Remote sensing allows for early detection of crop stress through analysis of specific wavelengths of light, enabling farmers to identify issues before visible symptoms appear. Tools like the normalized difference vegetation index (NDVI) provide insights into crop health, allowing for timely and targeted interventions. Hyperspectral and multispectral imaging further enhance disease detection by identifying physiological changes in crops that are not visible to the naked eye. In addition to disease monitoring, remote sensing aids in pest management by detecting changes in plant temperature profiles and utilizing drone surveillance for real-time data collection. Image analysis complements these efforts by offering detailed insights into crop conditions, enabling precision agriculture practices that minimize environmental impact and reduce costs. By integrating remote sensing and image analysis with other technologies like GIS and IoT, farmers can achieve more efficient, sustainable farming practices, ultimately leading to higher yields and better protection for grain legume crops.

ABSTRACT

Petroleum exploration is the art of searching hydrocarbon reserves in unknown regions by geological, geophysical and geochemical methods. The selection of effective exploration targets is an important step to achieve success in oil exploration and its selection also dependents on study of basic petroleum geological conditions. Petroleum geologists generally consider basins to be a basic geological unit for petroleum exploration and their main task is to find and determine various sedimentary basins. The remote sensing images have characteristics of really and macroscopic to provide accurate and visualization data for directly determining geometric shapes of sedimentary basins. Remote sensing techniques are more effective in understanding the study of basins in an out-of-the-way about mountains and remote deserts.

Key words: Petroleum Exploration, Sedimentary basin, geology, basin, geometry.

Reproduction is the backbone of animal production and productivity is the key to development. Reproductive inefficiency is one of the most important causes of economic losses in animal industries and it is realized throughout the world. Despite the remarkable advancement that has been made in the field of reproductive physiology in recent years, infertility due to low conception rate and high embryonic mortality rate remains a major problem. To meet future needs and to be able to sustain agricultural production, agricultural research and its applications need to use all emerging technologies one of which is modern reproductive biotechnologies.5 Thus, various assisted-reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or sub-fertile) animals in addition to disease control. Reproductive biotechnologies intend to be used routinely to shorten generational intervals and to propagate genetic material among breeding animal populations. To achieve this goal, reproductive technologies have been developed in generations over the years, namely artificial insemination (AI), embryo transfer (ET), manipulation of fertilization in vitro (IVF), cloning and transgenesis. These, together with sperm separation techniques, including that of selection of spermatozoa for chromosomal sex (commonly named sex-sorting) all face today a strong wave of increasing commercialization.9 Hence, this review paper highlighted the reproductive biotechnology options and their roles in the improvement of livestock production.
Roles of Reproductive Biotechnology in Animal Production
Biotechnology is defined as a technique that uses living organisms to make or modify and improve products. The emergence and development of reproductive technologies have been driven by the economic gain offered by the potential increase in the number of offspring from genetically superior animals or simply to safeguard the genetic pool of infertile or sub-fertile animals. In other words, reproductive technologies were developed to offer possibilities for wider use of superior germplasm.In recent times, there has been increasing challenges for

4.1 Introduction

Wheat (Triticum aestivum L.) is a major food security crop in South Asia, with 42% of the wheat in this region grown following rice (Oryza sativa L.) on 13.5 million hectares of land. Resource-conserving technologies offer considerable potential for improving the sustainability and productivity of wheat in the rice-wheat system of South Asia. These include raising input use efficiency, cutting costs, providing various environmental benefits, and ultimately improving farmer livelihoods and helping to reduce poverty.

History of Social Networking Services

The notion that individual computers linked electronically could form the basis of computer mediated social interaction and networking was suggested early on. There were many early efforts to support social networks via computer-mediated communication, including Usenet, ARPANET, LISTSERV, bulletin board services (BBS) etc.

Early social networking websites included Classmates.com(1995), focusing on ties with former school mates, and SixDegrees.com(1997), focusing on indirect ties. User profiles could be created, messages sent to users held on a “friends list” and other members could be sought out who had similar interests to yours in their profiles. Whilst these features had existed in some form before SixDegrees.com came about, this would be the first time these functions were available in one package. Despite these new developments (that would later catch on and become immensely popular), the website simply wasn’t profitable and eventually shut down. It was even described by the website’s owner as “simply ahead of its time.” Two different models of social networking that came about in 1999 were trust-based, developed by Epinions.com, and friendship-based, such as those developed by Jonathan Bishop and used on some regional UK sites between 1999 and 2001. Innovations included not only showing who is “friends” with whom, but giving users more control over content and connectivity.

Introduction

The development of DNA technology over the last few decades has led to generation of huge amount of data from plant and animal genome. The main sources of markers are mitochondrial DNA (mt DNA), minisatellites, micro satellites and anonymous nuclear sequences assayed using highly specific PCR primers or by using the RAPD technique. A major contribution comes from molecular markers used for analyzing genetic variations. There has been the infusion of computers, softwares and online databases into the daily activities of many molecular geneticists. The identification of abundant, highly variable loci, detectable by a wide variety of techniques has led to a revolution in the way researcher view and analyses levels of variation. We will here discuss about current computer programs in this area to characterize the DNA profiles and data analysis for intra and inter population structure, phylogenetic inference and parentage determination.

ABSTRACT

The present paper describes application of synergistic action of microalgae viz., Spirulina platensis, Chlorella vulgaris, and Oscillatoria princeps coupled with state-of-the-art microbial biotechnology (that involved strains of Bacillus subtilis, Nitrobacter winogradskyi, Aspergillus flavus, and A. niger) developed by Biotechnology Resource Centre (BRC), Mumbai for treatment of secondary liquid effluents from a gelatine manufacturing industry. The growth of mixed cultures of selected microbial and algal species was measured respectively in terms of Colony Forming Units (CFUs) and Optical density (O.D.) of the culture. The results were indicative of efficient degradation potential of the proteinaceous liquid effluents. Moreover their BOD and COD loads reduced by 30.75 % and 84.10 % respectively after the treatment. Furthermore, the bio-safety of algal biomass cultured in selected effluents as feed supplement was tested on Swiss albino mice (Mus musculus). Mice in treated group didn’t exhibit any observable adverse effect on their growth or on their reproductive performance. In fine, the liquid effluents of gelatine manufacturing industries were polished along with production of probiotic food supplement.

Need of Analytics in Fisheries Management

New technologies are introduced for industrial vessels every day: Fuel and gear sensors, cameras, electronic catch reports etc. There is a global push to track small-scale fishing vessel. In the coming years, fisheries monitoring centers will have to adjust from tracking a few hundred vessels to tens of thousands of vessels, meaning huge quantity of data. To make sense of all this information, it must be properly analysed. The future of fisheries depends on big-data analytics

This may help in many ways. Fishing trips could be tailored to meet quotas in the shortest time reducing fuel consumption and crew costs. Real-time catch data could help administrations close a fishing zone once quota is reached. Fisheries administrations can monitor catch efforts over an entire region and decide which zones to close, improving management of stocks and fishing licenses. Fighting the challenge of Illegal and Unreported fishing contributing to over-exploitation of fish stocks. Use of disruptive technologies in fisheries and aquaculture like block chains, sensors and automatic identification systems (AIS) has the potential to change the processes profitability and sustainability of the sector

Introduction

Data Analysis is an approach to analyse data sets to summarise their main characteristics and extract valid information. The importance of hypothesis is generally recognised more in the studies which aim to make predictions about some outcome. As it is not possible to work on the whole population, each group is represented only by a sample of observations and if another sample is drawn, the numerical values would change. This variation between different samples drawn from the same population cannot be eliminated or reduced fully. One is supposed to draw inferences in the presence of the sampling f luctuations. Statistical tools and techniques are applied to check whether the observed differences are real significant differences or non- significant ones.

Introduction

A population is the set of all objects we wish to study. A sample is part of the population we study to learn about the population. A census may be defined as an enumeration or evaluation of every member of a population. A parameter is any measurement that describes an entire population. A statistic is any measurement computed from a sample of the individual observations made. As per Best (1977), "Research is considered to be more formal, systematic, and intensive process of carrying on a scientific method of analysis."

Introduction

“Quality” of fish refers to the aesthetic appearance and freshness or degree of spoilage which the fish has undergone or involves safety aspects such as being free from harmful bacteria, parasites or chemicals. “Quality’’ is a term which must be defined in association with an individual product type. For example, it is often thought that the best quality fish is the one which is consumed within the first few hours of post mortem. However, very fresh fish which are in rigor mortis will be of hard texture and difficult to fillet and skin are often unsuitable for smoking or drying. Thus, for the processor, a slightly older fish which have passed through the rigor process are more desirable.

In today’s technology driven 21^st century, software has become an integral part of our day to day work. Starting from checking day’s schedule in tablet after waking up in the morning till setting up alarm before going to bed at night, we are using numerous software applications in a day without even realizing the efforts spent to make those applications work perfectly every time we use it. If we look deeply, each software application in computer or in any electronic/computer controlled device go through multiple rigorous cycles of testing to ensure that it is working as intended after it was built by developers and before it was launched in market for public use. In software industry, this process is termed as software quality assurance (QA) or software testing which is being considered as one of the most flourishing verticals of IT software services sectors in 21^st century.

Software testing is one of the most important phases of software development life cycle and it consumes anything between 10% to 45% of project budget depending on the type of the software and methodology followed in the development and testing life cycle. There are different types testing e.g. unit testing, integration testing, system testing, user acceptance testing, alpha, beta testing which are exercised during the testing phase and QA team needs to provide the sign off before any product is released and implemented in production or in consumer market. With the ever increasing complexity of today’s software products along with the competitive market due to easy availability of multiple product options/vendors, the importance and awareness of software quality assurance has increased over years. Consequently, various software testing methodologies have been evolved in last two decades in order to perform testing in more structured and controlled manner. In addition, there is a continuous urge for improving the operational efficiency of the testing process in the organizations in order to produce better quality software at less cost.

Tissue culture is the culture and maintenance of plant cells or organs in sterile, nutritionally and environmentally supportive conditions (in vitro). Conventional breeding methods are the most widely used for crop improvement. But in certain situations these methods have to be supplemented with plant tissue culture techniques, either to increase their efficiency or to achieve an objective not possible through conventional methods.

The art of Indian traditional knowledge regarding herbal medicine has a long history and can be considered as a potential source of new medicine. India has great potential in the market for herbal medicine, which is evident by the fact that medicinal plants required to prepare 50% of the drugs mentioned in the British Pharmacopoeia are reported to be present in the Western Himalayan region alone and India has approximately 8% of the world’s biodiversity, including plant genetic diversity with medicinal properties (Singh, 2006). Traditional medicine is widely used in rural areas, where 70% of the country’s population resides. Almost 75% of the medicinal plants grow naturally in different states of India. These plants are known to cure many ailments in animals.

Ethno Veterinary Practices

Ethno Veterinary Practices, also known as Traditional Veterinary Medicinal Practices are regarded as information gained over a period of time passed on from generation to generation. It is a community based functional knowledge system which has been developed, preserved and refined by generations of people through continuous interaction, observation and experimentation with their surrounding environment. Rural farmers mostly rely on ancestral ethno veterinary practices to deal with the diseases of their livestock and poultry. Veterinarians also show considerable interest in the medicinal plants, employed in traditional systems. This emerging trend in favour of herbal medicine is also due to the issues related to the antimicrobial drug resistance and drug residues in foods (milk/meat/eggs) of animal origin.

While System Software like device drivers and utilities enables the application software to interact with the computer hardware, Programming Software like compilers, debuggers and interpreters provides tools to assist a programmer in writing computer programs. However, most common users interact with their computers using Application Software, which enables them to carry out various daily tasks.

Application Software

Application software is programs that work with the operating system software to help the computer to do specific types of work. Applications are the pieces of software that perform tasks for the user besides helping the computer to operate (i.e. the task of system software). Applications range from games, calculators, and word processors (document creation programs). Application software can be easily divided by looking at exactly what function they serve. Listed below are some common types of software which one may encounter while using a computer.

Greenhouses have become an essential part of modern agriculture as they offer controlled environments for plant growth, research, and horticultural practices. This chapter discusses the various applications of greenhouses, which include extending growing seasons, improving crop yields, supporting botanical research, and producing ornamental plants. Additionally, it emphasizes the importance of repair and maintenance in greenhouse operations. Understanding the repair and maintenance protocols is crucial to ensure the sustained functionality of heating systems, water management, and structural components.

7.1 General

Science and technology have been advancing rapidly, but unfortunately, their impact has been largely negative. Pollution is not the only issue we face today, but also the depletion of fossil fuels, climate change, and excessive land degradation. The persistent presence of heavy metals in soil poses a significant threat to our planet. Many efforts have been made to remediate soils contaminated with toxic chemicals.

There are several issues that need urgent attention at the moment, and a solution is necessary to tackle them all at once. Biochar is a great option because of its numerous benefits, such as a large surface area, high porosity, high carbon sequestration rate, excess nutrients, and potential to produce syngas and bio oil. By using biochar, we can reduce the bioavailability of pollutants in soil, combat climate change by sequestering carbon, and reduce the use of fossil fuels by producing syngas and bio-oil. Additionally, biochar improves soil health, which can contribute to food security.
