Introduction

As Mahatma Gandhi, the Father of Nation, rightly pointed out that “The true India is to be found not in its few cities, but in its seven hundred thousand villages. If the villages perish, India will perish too”. (GoI website) Primarily India is an agrarian society, where more than 70% people lives in countryside. As majority of our population reside in rural hinterland and their livelihood depends on agricultural and economic activities related to it. People from rural areas migrating to mega cities or urban areas or industrial townships to seek jobs in service sectors. The seasonal migration of laborers to big cities has become a regular feature in our economy. These uprooted people feel lucky to get something to earn for near and dear ones. 58 per cent of these rural households are employed in farming sector i.e. cultivation, livestock rearing and other agricultural activity, which in turn contributes less than 60 per cent to their average monthly income. These were the findings of the ‘Situation Assessment Survey of Agriculture Households’ for the 2012-2013 crop years, from July to June. A brief overview of Indian economy reveals that agriculture contributes 16.5 per cent of the GDP contribution, compared to Industry’s 29.8 per cent and service sector’s 54.4, as per the census of 2015. It is also worth to recall that despite the big claim of booming Indian economy, the share of informal employment in total employment has remained above 90 per cent throughout the period 2004-05 to 2011-12, the Economic Survey 2014-15 revealed.

Mammary tumours arise from the ducts are called as ductal or ductular carcinoma. Some include other tissues such as the myoepithelium and connective tissue between the glands. These have a number of different names including carcinosarcoma, carcinoma or sarcoma in benign tumour, complex adenocarcinoma and malignant mixed tumour. Tumours are also classified by the type of epithelial growth because this influences the probability of recurrence. Tumours that only have myoepithelium or connective tissue are called sarcomas.

Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte.  Since volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand  to determine concentration. The volume of titrant reacted is called titre. Volumetric analysis originated in late 18^th-century in France.

Abstract

Remote sensing is the art and science of obtaining information about an object or phenomenon without having any contact with the object concerned. Geographical information system is a tool to create, manage, retrieve and query spatial databases. Remote sensing in conjunction with Geographical Information System (GIS) has wide applications in all spheres of life and especially in agriculture. Specifically, this paper reveals some of the applications of remote sensing and GIS in the field of crop condition assessment viz., crop type classification, crop stress detection, crop yield estimation and pest and disease monitoring.

Keywords : Remote Sensing, GIS, Yield Forecasting, Crop Stress, Pest and Disease Monitoring

1.0 Introduction

Remote sensing is the art and science of obtaining information about an object or phenomenon without there being any physical contact. The information is so collected using a device called a sensor. The sensors are mounted on a platform at an advantageous position. Accordingly the remote sensing is called ground based (sensor is hand held or mounted on mast), air borne (sensor is on a balloon or aero plane) or space borne (sensor is mounted on a satellite). The basic principle in remote sensing is that each and every object has unique reflecting property like human thumb impression and when the solar energy is falling on an object a part of it gets reflected, which carries the information about the object. The reflected light is converted in to reflection percentage of incoming solar radiation. This percentage of reflection can be used to work out the vegetation indices which are surrogate measure of crop condition.

Geographical Information System (GIS) is software system which enable Collection of large volume of data with spatial relation Integration of data from different source is possible Analyze such data for our requirement Present the data in different formats (maps, table and reports)

The wide range of climatic conditions in India provides a choice of various bulbous crops to grow them in different parts of country. The term bulbous includes a wide array of perennial plants that are grown from underground organs, including bulbs, corms, tubers and rhizomes. Any plant described as bulbous will normally have a swollen root or stem or even leaves underground. A large number of these plants producing attractive flowers are commercially grown now days. Normally bulbous plant has a three phases during a year growth, flowering and dormancy. Bulbous plants are grown commonly in beds, shrubbery, herbaceous border, grassy land and in pots and bowl. A brief description of some common bulbous crops is given below.

1. Amaryllis: Common name (CN): Belladonna lily, King or Star lily, Botanical name (BN): Amaryllis spp., Family (F): Amaryllidaceae, Origin (O): South Africa.

Amaryllis is an excellent bulbous plant with deciduous foliage. Leaves are produced after cessation of flowering. It is suitable for bedding, pot, window boxes, greenhouses, borders, etc. Flowers are sold in the market as cut flowers. The flowers are large, trumpet shaped and are borne in umbels having 3-7 florets in small flowered varieties whereas 2-4 florets of giant size in Dutch hybrids. Amaryllis is propagated by vegetative means. They are mostly propagated through bulbs. They are also commercially propagated through tissue culture. Important species are Amaryllis belladonna, A. angustifolia, A. leopolidii, A. moreliana, A. papilio, A. striata, A. miniata and A. traubii.

Hazard Analysis Critical Control Points (HACCP) is an internationally recognized method of identifying and managing food safety related risk and, when central to an active food safety program, can provide customers, the public and regulatory agencies assurance that a food safety program is well managed. HACCP is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. (FAO, 2003)

Mycotoxin hazard analysis and identification of possible control measures

I. Hazard Analysis

a) Identification of mycotoxin hazard

For a given commodity system in a particular location, the HACCP team need to first consider which, if any, of the mycotoxins known to constitute a food safety hazard are likely to be present. Over 300 mycotoxins are known, but only a relatively few of these are widely accepted as presenting a significant food or animal feed safety risk.

The following mycotoxins have regulatory limits set by one or more countries: the aflatoxins (including aflatoxin M₁), ochratoxin A, zearalenone, patulin, ergot alkaloids, and deoxynivalenol. Guideline limits exist for fumonisin B₁ and regulatory limits are likely to be set in the near future. The regulatory limits are taken as the target levels and should be included in the Product Description table. Mycotoxin limits can also be set by the customer in specific contracts and it is possible that these may include mycotoxins not subject to regulatory limits.

2.1 Introduction

Dear students, you shall be taught plant biotechnology during the third semester in the course ‘Elementary Plant Biotechnology’. But, for understanding of non-conventional breeding methods/techniques you should acquire some knowledge of basic plant biotechnology. Hence, in this chapter plant biotechnology is introduced to you in brief.

2.2 Definition

The term ‘biotechnology’ stems from fusion of ‘biology’ and ‘technology’. It was coined by Karl Ereky, a Hungarian agricultural engineer, in the beginning of 20th century. According to him, all processes used to yield finished products from raw materials with the help of living organism come under biotechnology. It may be defined in number of ways. However, in simple terms, biotechnology may be defined as ‘the controlled use of biological agents, such as microorganisms, or cellular components, for beneficial use’ (U.S. National Science Foundation).

The problem of frost damage to the crops is as old as agriculture is. Earlier, crop production was undertaken only as per the geographical distribution of the plant species and the cultivation of crops in non-conventional areas was not there. Later, with the expansion of agricultural activities, a number of introductions were made in the non-conventional areas. 

Opportunities

India is home to largest milch animal population, totalling around 100 million cattle and buffalo (out of total population of 300 million) spread over 6.5 million census villages. India is the largest milk producer with CAGR of 4.5%, likely to go up to 5%, which is likely to create around 20 million jobs every year. The most significant factor is that dairy industry is likely to exceed IT industry in employment generation. In year 2018, India produced 146 million tonnes of milk contributing 26% of the agriculture GDP.

But the foundation of dairy industry is economically vulnerable as per animal productivity and fertility are very low leading to meagre profits and frequent demands to enhance procurement price. National schemes like Operation Flood, National Dairy Plan-I and National Dairy Plan II, largely focussed on milk collection, processing, distribution and organising farmers but the animal component has been neglected. Enhancing per animal productivity by empowering farmers to scientific management and breeding to achieve genetic improvement needs urgent attention. Although numerous technologies to improve health and genetics are available but the single most important gap is failure to deliver these to farmers. Unlike western world, India has not been able to develop modern veterinary service delivery models. In order to cater to breeding and health services of cattle and buffalo (300 million in numbers) and also pet animals in rural areas and small towns, huge manpower and infrastructure will be required.

Introduction
Video and audio editing encompass two primary modes: online and offline editing, each critical for producing high-quality, synchronized media content. Online editing refers to real-time editing with high-resolution files, typically as a final step in the post-production workflow. Offline editing involves working with lower-resolution copies or proxies of footage for easier manipulation and organization, saving time and computational resources. Both techniques hold unique advantages and can be integrated depending on project requirements, available resources, and editing goals.
Section 1: Understanding Offline Editing
1.1 Overview of Offline Editing
Offline editing is the preliminary editing stage where editors work with lower-resolution copies of the original footage to perform initial edits. This approach optimizes efficiency, as low-resolution files consume less storage and processing power. Common in projects with extensive footage, such as feature films, documentaries, and complex multimedia presentations, offline editing allows editors to focus on the structure, sequencing, and timing of content without concerns over resource demands.

Fish-Cattle Integrated Farming blends aquaculture with cattle husbandry, fostering a mutually beneficial system where animal waste supports fish production. This integration increases productivity, cuts costs, and provides diverse income and food sources. Organisms resulting from indirect feeding are protein-rich (50–60% dry weight), so carbohydrate-based agricultural waste like rice bran can serve as direct feed. This blend of indirect and direct feeding—animal manure plus agricultural by-products—enhances fish yields. Jhingran and Khan (1979) found that an initial application of 10,000– 15,000 kg/ha of cow dung is a cost-effective way to fertilize ponds. Staggered applications—10,000 kg/ha 15 days before stocking and 5,000 kg/ha 7 days after— sustain plankton productivity. Adding 1 kg/ha manganese (MnSO?.H?O) following 20 kg/ha P?O? also boosts plankton growth. For nursery ponds, a fertilizer mix includes 150 kg of superphosphate, 50 kg of triple phosphate, 700 kg of cow dung or equivalent, and 700 kg of oilcake, all turned into a paste and spread across the pond. It is then inoculated with 30–50 ml of Daphnia and Moina. Two days after stocking, 350 kg oilcake and 87.5 kg cattle dung/ha are applied. At the Central Inland Fisheries Research Institute (CIFRI), Barrackpore, rearing ponds were treated with 11,230 kg/ha cow dung 10 days before stocking. A mix of ammonium sulphate, superphosphate, and calcium ammonium nitrate in a ratio of 11:5:1 was applied at 690 kg/ha two months post-stocking. For production ponds, the advised input includes 1000+ kg cattle dung, 560– 1200 kg poultry manure, and 5000 kg green compost/ha. The standard inorganic fertilizer mix is N:P:K = 18:8:4. CIFRI reports good results from combined application of 20,000–25,000 kg cow dung/ha/year (in 7–11 doses) with ammonium sulphate + superphosphate + calcium nitrate (1380–1725 kg/ha/year in 4–10 doses).

Medicinal and aromatic plants have been known for millennia and are rich source of therapeutic and cosmetic agents for the prevention of health diseases and critical skin ailments. India is the rich source for the medicinal and aromatic plants and export many plant parts for the research work to the many countries as raw materials. The major market in the world for essential oils is the United States, followed by Japan and Europe. However, production continues to be concentrated in Europe, with seven of the world’s largest essential oil processing firms. In the United States, the major users of essential oils are the soft drink companies. Japan accounts for 10 % of the world demand. The Canadian market is domi­nated by the United States perfume and flavouring industry. France is dominating the world perfumery market, and Switzerland is one of the leaders in the pharma-ceutical field. Britain and India are known to feature strongly in the flavouring sector. The essential oil industry is characterised by a number of difficulties, including lack of stable quality, inconsistent supplies, and variability of active ingredients owing to environmental effects. Even though according to World Health Organization, herbal medicines are lucrative globally and represent a steady high market value in every year.

Rice (Oryza sativa L.) is the most popular crop and source of food for more than one-third of the world’s population. About 90 % of the world’s rice is grown in Asia and more than 3 billion Asians rely on rice for 30–75 % of their total calories (Braun and Bos 2004). It has been cultivated in four different ecosystems viz., irrigated, rainfed low land, upland and flood-prone (Halwart and Gupta, 2004). Since rice planting has been started around 8,000 to 9,000 years ago, the level of diversity would be more than it expected. The genetic diversity plays a major role in survival and adaptability of a species, as changes happen in environment. Organism needs to make changes in the phenotype that enables it to adapt and survive in unfavorable conditions. The inadequate knowledge on diversity of a species reduces the chance of widening the genetic base of that species. The venture of green revolution in Indian agriculture has narrowed down the genetic base of any popular crops. Therefore, collection, conservation and utilization of germplasm are very much needed in the present scenario for improving the varieties against biotic and abiotic stress.

Morphological and biochemical trait based diversity studies being largely influenced by environment as phenotype and/or enzymes are altered by the environmental and developmental changes. Therefore, adapting DNA based molecular markers for genetic diversity studies would be more reliable to overcome the environmental influence. Being molecular markers as a versatile tool, it establishes its strong holds in several fields of life science. Molecular marker based technique does not require DNA sequencing but it is generally based on nucleic acid hybridization or polymerase chain reaction (PCR). The PCR based tests has several advantages over hybridization technique as it is cheaper, speedy and sensitivity. Therefore, PCR based markers have been used extensively in genetic diversity study for assessing genetic variation within the species. The recent advent of molecular and computational tools now enables the estimation of genetic diversity and allele frequency between the genotypes easy.

INTRODUCTION

Variability in different organisms is common feature and is an important process for the continuity of life under stress conditions. Plant pathogens especially fungi, bacteria, virus and nematode show variations in their pathogenic potential (virulence) and physiological functions that support their survival and perpetuation in different environmental conditions. These variations may be largely due to genetic factors that may be conditioned by environmental factors. Various studies on genetic variability of microbial plant pathogens have shown that variations may occur in characters which affect their ability to infect host plants and also other characters that do not alter the pathogenic potential, but they may be concerned with their survival. Knowledge of variation in pathogenic characteristics is valuable in planning effective measures for disease management. In addition, development of resistant to fungicides has been a serious concern to growers, researchers as well as the administrators, since the decision to continue application or withdrawal of a fungicide can affect both the growers and industry.

Biometrical genetics: This is a branches of genetics which uses the statistical concept and procedures for the study of genetic principles.

Local government is essential for responsive governance, citizen participation, effective service delivery, and sustainable development at the grassroots level. It ensures that decisions are made with the best interests of the community in mind, leading to improved quality of life and overall well-being for its residents. Local government ensures that decision-making is participatory, responsive, and tailored to the needs of the community, promoting effective governance and sustainable development at the grassroots level.

The quality of essential oils is very complex. An individual oil may have hundreds of ingredients, the principle components being a group of complex substances known as terpenes and their compounds or derivatives. Due to this reason a single essence has a wide range of therapeutic actions.
The chemical constituents of plants are of two kinds: products of primary metabolism and products of secondary metabolism. The first are mainly carbohydrates, amino acids and fixed oils produced by light-absorbing (photosynthetic) processes. The latter group of chemicals arises from the primary metabolites. They include glycosides, terpenoids, alkaloid and essential oils. Essential oils lack the water soluble constituents such as tannins,
bitter compounds sugar, mucilages and pectins, playing important role in the medical action of the plant.
The essential oils have been credited with possessing almost all therapeutic properties in a concentrated form. The therapeutic properties of the whole oil are that result of synergism: an interaction of all its chemical constituents working harmoniously together so that the whole essential oil becomes more potent than the sum of its individual parts.
The essential oil lacks certain chemical compounds found in the raw plant material. It is still a highly complex substance, that it cannot be replicated in the laboratory. Even though high-tech processes such as gas liquid chromatography (GLC) can separate out main constituents of essential oils. By looking at the chromatogram, it is impossible to isolate the numerous trace elements including number of unidentified compounds which make up
the whole.
