Abstract

During present investigation a comparative study was done to see the effect of storage on physical properties of tomatoes (Lycopersicon esculentum Mill) packed in HDPE and stored under ambient temperature. Four varieties of tomatoes taken for current investigation were Badshah, Himshikhar, NS-524 and Raja. From the studies it was clear that TSS increased gradually during storage duration for entire tomato varieties due to loss of some moisture from tomatoes. Variety NS-524 shows maximum shrinkage among all during observation period.

As the ornamental fish industry expands throughout the world, genetic considerations have become more important in terms of production, sustainability and conservation. Genetic technologies are now being applied to increase food production in aquaculture through traditional and modern breeding programmes. Genetic markers can help to manage capture fisheries and distinguish farmed from wild stocks in mixed fisheries. Genetic technologies are also now finding application in post-harvest and trade to assist in product identification and traceability. Genetic improvement of fish has considerably increased the fish production from aquaculture. It includes selective breeding, hybridization, polyploidy, gene and nuclear engineering. For any genetic selection programme, induced breeding is the basic and initial step. Intensive selective breeding is practiced with various species of fish in perfecting appearance, shape and color so that new strains are produced.

Domestication

Most of the fish being widely grown in captivity are domesticated to some extent, but there are very few which have undergone genetic improvement. Just as terrestrial livestock and crops are bred to be not only productive, but productive in convenient proximity to humans, aquatic plants and animals are now undergoing these same pressures.

In comparison to agriculture crops, fruit plants and animals, aquaculture is much behind with regard to the domestication of the fish, especially ornamental fish. Never the less, a good number of ornamental fish have been domesticated which can be considered for selective breeding to improve their traits. The available technologies and tools could be used to remarkably speed up domestication and genetic improvement process.

Domestication implies much more than merely keeping wild animals in farms or homes. Domestication is a very long process, during which captive individuals become more adapted to captive environments. Domestication leads to permanent genetic modifications of a bred lin-eage, while taming or keeping wild fish in captive conditions is only conditioned behavioral modification of individuals. The entire life cycle of the domesticated fish species must be fully closed in captivity. Once full life cycle is completed in captivity, the process of domestication can proceed further.

The first truly domesticated fish species was certainly the goldfish, for which the domestication was initiated by the Chinese about 1500-2000 years ago.

Cropping system is defined as the cropping pattern followed on a farm and its interactions with farm resources, other farm enterprises and production technology. The yearly sequence and spatial arrangement of crops and fallow on a given area is termed as cropping pattern.

India has over 17% of world’s population living on 2.4% of the world’s geographical area. Per capita agricultural land has reduced by 67% from 0.48 ha in 1951 to 0.16 ha in 2008 due to explosive increase in population. In this situation, it is very difficult to get horizontal expansion in vegetable cultivation. Hence, total production per unit area can be increased by increasing the productivity per unit area through (a) growing improved high yielding varieties and hybrids, (b) adequate and scientific crop management practices and (c) increasing cropping intensities following different cropping patterns.

Introduction

Our traditional knowledge of medicine has been one of the strongest areas of research because of our rich heritage in herbal plants & great biodiversity in our fauna & flora. Consumption of plant foods and the structurally diverse natural products provided by them have long been associated with health-protective and therapeutic effects. Natural products in plant foods have been shown to have pleiotropic therapeutic and chemopreventive properties. These bioactive products are known to potentiate the efficacy of other drugs and have synergistic effects too. Most of the prescription drugs discovered so far is from plant sources and 75% drugs had been claimed in folklore claims and traditional medicinal system (Reynold, 1991; Benowitz, 1996). The traditional Indian medicinal system utilizes multicomponent formulations of plant extracts which may either act synergistically or avoid many side effects and might have added up trace element through combination of different plant extracts which could have additive effects. However the effort to utilize traditional knowledge in the light of modern scientific findings is lacking in India. Accumulating evidences as well as in-vitro studies implicates inverse relationship between regular consumption of fruits vegetable and the risk of specific cancer. Diet derived nutritional compound mediated interventions in the process of tumorigenesis may be promising chemopreventive strategy with minimal toxicities to the physiological system.

Any organism with other than two basic sets of chromosomes, that is, monoploid, triploid, tetraploid, and various aneuploids is termed as polyploid. There are several economically important crops which are natural polyploids emphasizing the economic importance of polyploids in agriculture. These are:

Triploid-Banana

Autotetraploid-Alfalfa, potato, coffee, peanut or groundnut Autohexaploid- Sweet potato

Amphidiploid/allopolyploid-Wheat, cotton, oats, Brassica species (B. carinata- Ethiopian mustard, B. juncea-Indian mustard, B. napus--rapeseed), sugarcane

Man-made commercially successful allopolyploid- Triticale

Introduction

Agriculture is an important sector of Indian economy and it contributes about 17.4% to the country’s Gross Value Added (GVA) for the year 2016-17 provides employment to over 54.6 % of the population. There has been a continuous decline in the share of agriculture and allied sector in GVA from 18.6% in 2013 14 to 17.4% in 2016-17. Falling share of agriculture and allied sector in GVA is an expected outcome in a fast growing and structurally changing economy. However since 54.6% of the population is still dependent on agriculture and engaged in improving the agricultural production and overall income. The agricultural production system required timely and adequate agriculture credit to fulfill farmers need. Agricultural Finance ensures provision of multiple types of services dedicated to support both on- and off-farm agricultural activities and businesses including input provision, production, and distribution, wholesale, processing and marketing.

Introduction

India is the third largest producer of cotton in the World. The cotton farmers of India are facing many problems. The stories of Vidharba are crucial lessons for the technocrats and policy makers. Most of the cotton growing areas are dry tract hence grown as rain fed crop. An amount of Rs. 12 billion worth of pesticides are used to control the serious pest i-e boll worm. In order to make the farmers to live debt free life and ensure the maximum reach out efforts of extension, it, needs a strategic TOT efforts.

In this juncture introduction of Bt cotton is a phenomenal change in the cotton industry and needs a careful practices to increase the adoption since it has some complex issues like growing refugee crops. TOT of Bt cotton is unique because of its newness attracts positive and negative comments. A study to assess the acceptance, non adoption and constraints related to Bt cotton was carried out and the findings are given below.

Abstract

Garden peas of two cultivars (Pb-87 and Pb-88) were procured. Pods were shelled manually, grains were blanched and dehydrated. Other lot of peas of both the varieties was allowed to mature on the plant till the plant foliage dried up, harvested, pods were dried in shade for few days, shelled manually and grains were further dried in shade. Grits were prepared by grinding rice and pea (dhal) in a laboratory grinder to pass through 20 mesh sieve. Blends were prepared by mixing rice and pea grits in the ratio of 100:0, 85:15 and 70:30. The blends were subjected to extrusion cooking using Brabender single screw extruder. The extruder die pressure, specific energy consumption (SEC), expansion ratio, density, water absorption index (WAI), water solubility index (WSI) and organoleptic characteristics were studied. Addition of pea grits resulted in a decrease in die pressure in all the blends. Addition of pea grits showed a significant effect on SEC. A decrease in expansion with increase in the level of pea grits in blend was observed. The extrudates having lower expansion showed higher density values and vice versa. Effect of replacement of rice grits with pea grits on WAI was found to be significant. Level of pea grits significantly affected the WSI. Incorporation of pea grits in the rice grits significantly affected the sensory characteristics. Replacement of rice grits with mechanically dried pea grits resulted in deterioration of acceptability score, but addition of field dried pea grits improved the same.

Food Hygiene is a scientific discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness. This includes a number of routines that should be followed to avoid potentially severe health hazards. Food can transmit disease from person to person as well as serve as a growth medium for bacteria that can cause food poisoning. Since food hygiene has a direct effect on the health of individuals patronizing the catering facility, it is obligatory on the part of the management to lay down definite guidelines for maintaining hygienic conditions and ensuring their proper implementation. Cleanliness should be the basis of all food hygiene programmes and should be aimed at food protection as well as improving and maintaining the quality of food. 

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.

Tourism is a phenomenon, which has taken off immensely in the past three decades. It concerns us all, be it by allowing us to travel long distances as tourists, or by forcing upon us a mass of visitors to our part of the world. In the past, people did not travel half as much. Financial obstacles and responsibilities to land and animals stopped them from doing so. Only in 1845 did Thomas Cook of Leicester, England, organize the first package tour, making this experience available to people outside of the privileged classes by cutting down on expenses. By 1939, an estimated one million people were traveling abroad each year. Nowadays, the population of the Mediterranean swells to double over the summer, from 130 million resident inhabitants during the winter to 260 million in high season. There were about 698 million international tourist arrivals worldwide in 2000. All regions in the world grew, and the fastest developing region continued to be East Asia and the Pacific. Tourism has become the largest industry in the world. And just like all thriving industries, though it has a lot to give, it also takes a lot in turn. Unfortunately, the toll that we pay for it has been rising steadily. While the prospect of people traveling less in the future seems improbable, to say the least, a new idea has already sprung up: If we cannot stop tourism, let us at least travel sensibly.

An agriculture supply chain system comprises organizations/cooperatives that are responsible for the production and distribution of vegetable/Fruits/Cereals/ Pulses or animal-based products. In general, we distinguish two main types:

‘Agriculture food supply chains for fresh agricultural products’ (such as fresh vegetables, flowers, fruit). In general, these chains may comprise growers, auctions, wholesalers, importers and exporters, retailers and speciality shops and their input and service suppliers. Basically, all of these stages leave the intrinsic characteristics of the product grown or produced untouched. The main processes are the handling, conditioned storing, packing, transportation and especially trading of these goods.

Constitution

The word ‘constitution’ is derived from a Latin word “Constituere” that means to set up or to make up or to establish. Therefore, it is the structure, composition, physical make up or nature of something consisting inherited qualities modified by environment. Constitution in homeopathy is defined as the physical and mental makeup which is expressed through physical built, characteristics, desires, aversions, reaction including emotional and intellectual attributes. In other words constitution incorporates the individual’s combined physical body type (including nervous system and metabolism), mental thinking, style, emotional reactivity and temperament.

Classification of constitution

Human constitution has been classified in different ways in different systems of health care.

The tropical fruit guava is prone to a number of diseases, pests, and disorders. Aphids, fruit flies, and scale insects are common pests; on the other hand, pathogens, such as bacteria and fungus, can cause illnesses like wilt and anthracnose. Deficiencies in some nutrients can occur and have an impact on the general health of plants. For effective control, integrated pest management must be put into practise along with routine inspections and prompt treatments. Maintaining a healthy guava crop involves disease-resistant cultivars, balanced fertilisation, and good orchard cleanliness. A vigorous guava crop is ensured by minimising the influence of diseases disorders, and pests via vigilant and preventative methods.
10.1 Weed control
Weeds should be kept under control throughout the year because fruit harvesting is done throughout the year, for the easy mobility of labour. For this purpose, spray Gramoxone @ 6ml/litre of water during March, July and September. To control perennial weeds in March, spray may be done with Round up (Glyphosate) @ 10 ml/litre. Spray of these weedicides should be carried out on a calm day to avoid the damage to guava foliage.
10.2 Insect pests
10.2.1 Fruit fly
Fruit fly, the serious threat to guava production particularly during rainy season, lays eggs singly in ripened fruits just below the epicarp which eventually results in appearance of minute depression with dark punctures. Maggots after hatching feed on pulp and make fruit unfit for consumption. They pupate in soil and takes about 12 to 18 days to complete its life cycle during July- August (main season).

In cropped soils, evaporation refers to evaporation of water from the soil and transpiration refers to evaporation of water from plant canopies (Fig.6.1). Evaporation and transpiration play very significant role in mass and energy transfer. The latent heat of vaporization is defined as amount of heat required to evaporate 1 gm of water at a temperature of 100°C; i.e. the boiling point of water is 540 cal/gm. The amount of heat required for evaporation of water at ordinary temperature of about say 30°C is 610 cal/gm.
Fig. 6.1: Process of evapotranspiration
The evapotranspiration from crop depends upon several factors as indicated below:
• The evapotranspiration increases with increase in air temperature.
• The evapotranspiration increases with increase in wind speed up to a certain limit.
• The evapotranspiration decreases with increase in relative humidity
• The evapotranspiration increases with increase in Saturation Vapor Pressure Deficit (SVPD). SVPD = es – ea

The integration of Large Language Models into software development has created powerful capabilities for automated code generation, debugging, testing and application development. However, AI-generated code can introduce security vulnerabilities when models produce incorrect, unsafe or poorly validated programming solutions. This chapter examines the need for security-aware frameworks that combine LLM-based code generation with verification, rule-based evaluation and risk management. It considers the limitations of conventional rule-based systems, including rule explosion, inflexibility, maintenance overhead and limited personalization, and explores how AI-driven approaches can improve adaptability while maintaining safeguards. Particular attention is given to secure integration in sensitive domains such as healthcare, where generated code and automated analytical systems may influence clinical information and decision-making. The chapter considers data-driven evaluation, machine learning, genomic information and risk detection as components of secure AI systems. It emphasizes the importance of validating generated code rather than treating model output as automatically reliable. Secure deployment requires testing, human oversight, access controls, verification mechanisms and continuous monitoring. The chapter therefore presents safe LLM integration as a multidisciplinary challenge combining AI capability, software engineering, cybersecurity and responsible governance.

Both women and men play critical roles in agriculture throughout the world, producing, processing and providing the food we eat. Rural women in particular are responsible for half of the world’s food production and produce between 60 and 80 percent of the food in most developing countries. Yet, despite their contribution to global food security, women farmers are frequently underestimated and overlooked in development strategies.

Rural women are the main producers of the world’s staple crops – rice, wheat, maize – which provide up to 120 percent of the rural poor’s food intake. Women sow, weed, apply fertilizer and pesticides, harvest and thresh the crops. In the livestock sector, women feed and milk animals, while raising poultry and small animals such as sheep, goat, etc. Also, once the harvest is in, rural women provide most of the labour for post-harvest activities, taking responsibility for storage, handling, processing and marketing.

Medicinal plants and their various products are extensively utilized not only in traditional systems of medicine but also in modern medicine throughout the world. In recent times, they have also attracted attention of scientists encompassing various disciplines of medicine and biotechnology for search of new drug molecules and modern drug development. Although several research strategies are followed for drug development only the traditional, empirical and molecular methods/strategies are mostly applied. There is also need of scientific validation for safety, efficacy and rational use of traditional form of medicine along with development of standards for identity, purity and strength (Singh and Bagchi, 2002).

Approaches of Drug Developement

Following approaches are generally employed to discover and invent new therapeutic agents from plants viz. screening of plant materials, identification of active constituents, pharmacological and clinical evaluation and drug design.

Hypothesis testing is the statistical procedure used in order to accept or reject statistical null hypotheses. One of the major purpose for which we formulate the hypothesis is, to test the statistical significance of the relation, difference or variation etc. among given sample/s at a given point of time or at different time points.
