Introduction

Humans primarily get their nourishment from agriculture. According to the most recent UN estimates, the population of the globe could increase to over 9.7 billion in 2050, and to fulfill the demands of an expanding population and a rising need for food, the energy demand in the agricultural sector has dramatically expanded. However, a farm that produces food needs a steady supply of energy to run the machinery, irrigation pumps, and other devices that are often powered by fossil fuels. Because of the ongoing demand for energy, there is growing concern that these fossil fuels will also run out soon (Aroonsrimorakotet al., 2020). Additionally, other global issues like climate change, water shortage, and energy security are just a few variables affecting agricultural production that require more environmentally friendly and sustainable farming methods As a result, it is crucial to maximize land usage and increase agricultural production through the deployment of cutting-edge farming techniques and new technology for both economic effectiveness and the best possible use of the limited resources available in the form of land. There are many distinct uses for renewable energy in agricultural systems. Renewable energy sources can also be used to generate electricity for a range of agricultural tasks (Torshizi and Mighani, 2017). Renewable energy can come from a variety of sources, but solar energy is the ideal option because it can be installed practically anywhere on the field, is pollution-free, and is also the most economical. Unlike the usage of fossil fuels, using solar energy doesn’t release greenhouse gases. For remote locations with erratic access to electricity, it is the best renewable energy choice. Applications for space and water heating, greenhouse heating, solar photovoltaic systems, and water pumps for irrigation using various forms of solar energy technology (Mekhilefet al., 2013). There are numerous benefits of using solar energy technologies, such as solar panel water pumping systems, aside from being free of fuel costs, solar panels also have lower maintenance costs and require fewer replacement components than generators powered by diesel engines. In order to meet the growing demand for agricultural products from the expanding population, agriculture is a sector that aspires to accept the usage of solar energy and reaps enormous benefits from it. Therefore, solar energy technology has emerged as a solution in order to boost economic benefits to farmers and improve the environment by reducing CO2 emissions into the atmosphere, thereby addressing the issues caused by a growing population and a shrinking amount of available resources (Aroonsrimorakot and Laiphrakpam, 2019). The potential for farmers to move from using fossil fuels to using renewable alternative energy, which might lead to produce superior in both quantity and quality of food produced in various kinds of agricultural farms (Bardi et al., 2013). The issue will get worse unless the farmers change their perception about the adoption of solar energy technologies. Therefore, it is advised for farmers to employ energy-saving tools for producing crops and to maximize land by installing solar energy systems because they are practical, affordable, and useful for a variety of tasks (Duprazet al., 2011). Since many people still solely rely on fossil fuels for energy and lack access to modern energy sources, in light of this, the current study was done to assess the level of awareness and adoption of solar energy in agricultural operations.

INTRODUCTION

Lily is one of the most important ornamental bulbous plants. It comprises one of the distinctive flowers in form, appearance and colour. The flower stems of lily are long and sturdy with luxuriant foliage and it has longer vase life. Lilies are very useful flowering plants which can be planted in any location as they do well in the bed or border with other perennial. Almost all varieties of lily are suitable for planting in combination with other plants and in front of tall shrubs. They look very charming in large clusters for mass effect. Shorter varieties are planted in containers. Lilies may be planted in the perennial border, preferably with the plants having ample foliage. They seem to have fascination for some companion and thus can be grown with other flowers in the garden. The bulbs of some varieties of lily are edible and somewhat bitter in taste but fairly pleasant when properly cooked. In China, bulbs of tiger lily are prefered as food due to its specific taste. Lilaline, an alkaloid is also found in the flower of some lilies. Lily has several medicinal properties. The bulb is diuretic, emmenagogue, emollient and expectorant. The flowers are carminative. They are used to strengthen the eye lid muscles and are commended in the treatment of myoptic astigmia.

Among the lilies, two groups have been evolved through extensive improvement and referred as coloured lilies and extensively grown for cut flowers and other popular type is generally grown for garden display in India. Asiatic and Oriental lilies are leading cut flower group and in the international market. It is dominated by the Netherlands. An oriental hybrid cultivar Tiara is developed. It is true pollen free lily, excellent for bouquets. Oriental and Asiatic hybrid lilies are compact, with plant height of 60 to 150 cm that bears many flowers. Spikes of 10 to 15 cm flower diameter that may point up, out or down. Blooms may be red, pink, orange, yellow, lavender or white in colour. They grow well in full sun or light shade, although flowers sometimes fade if exposed to hot sun. They can be grown with companion plants providing less competition. Popularity of Oriental lily is increasing over Asiatic lily.

Introduction

Biofertilizers are microbial preparations containing living or latent cells of efficient strains of nitrogen fixing, phosphate solubilizing and cellulose decomposing microorganisms intended for seed or soil application and designed to improve soil fertility and plant growth by increasing the number and biological activity of beneficial microorganisms in the soil.

The objects behind the application of biofertilizers /microbial inoculants to seed, soil is to increase the number and biological / metabolic activity of useful microorganisms that accelerate certain microbial processes to augment the extent of availability of nutrients in the available forms which can be easily assimilated by plants. The need for the use of biofertilizers has arisen primarily due to two reasons i.e. though chemical fertilizers increase soil fertility, crop productivity and production, but increased / intensive use of chemical fertilizers has caused serious concern of soil texture, soil fertility and other environmental problems.Use of biofertilizers is both economical as well as environment friendly. Therefore, an integrated approach of applying both chemical fertilizers and biofertilizers is the best way of integrated nutrient supply in agriculture.

Biofertilizers, thus include i) Symbiotic nitrogen fixers- Rhizobium sp. ii) Non-symbiotic, free living nitrogen fixers- Azotobacter, Azospirillum etc. iii) Blue Green Algae (BGA) inoculants- Azolla-Anabaena, iv) Phosphate solubilizing microorganisms (PSM)- Bacillus, Pseudomonas, Penicillium, Aspergillus etc. v) Mycorrhiza vi) Cellulolytic microorganisms

1. Introduction

Thermal processing used extensively in the food industry for preservation and shelf life extension of the products (Arnoldi 2001). Heat treatments remain most important in food processing unit operations, not only to achieve desirable changes in eating quality but also for preservative effect by inactivation of microorganisms, destruction of enzymes and insects.Heat is applied in various unit operations through adifferent mode of heat transfer such as conduction, convection, and radiations. 

Introduction

Agriculture forms the backbone of the Indian economy. Although there has been large industrialization in the last 60 years, agriculture still occupies the prominent place of importance (Banarsi Lal, 2019). The agriculture sector contributes about 20 per cent of GDP in India (MoF, 2020-21). Both the agriculture and livestock sectors provide employment to 52 per cent of the work force (Rathod and Dixit, 2019). In India, most of farmers have small average holdings. Agriculture marketing can play important role in increasing income of farmers with same landholding. Agriculture plays a vital role in India’s economy. 54.6 of the total workforces is engaged in agriculture and allied sector activities (Census 2011) and accounts for 18.8% (First Advance Estimates) of country’s Gross Value Added (GVA) for the year 2021-22 (at current prices). Agriculture sector needs structured and functional markets, preferably in the vicinity of farmers, to drive growth, employment, remunerative prices and economic prosperity in rural areas of the country.

9.1 Introduction

Water is essential for all life and used in many different ways. It is an important part of the ecosystem in which the reproduction of the bio diversity also depends. Fresh water scarcity for agriculture, industry and household purpose is not only limited to the arid climatic regions, but also in areas having high rainfall. Water scarcity is caused by low water storage capacity, low infiltration rate, high evaporation demand and larger inter annual and annual fluctuations of precipitation.

Introduction

It includes different levels of competitive strategy and how generic competitive strategies can be formulated. The organisation need to understand how to tackle the competitors and what specific decisions to be taken while formulating a competitive strategy. Each type of industry has to plan its own competitive strategy either to grow or to come out in bad situation. Michal Porter described generic competitive strategies to cope with five competitive forces. These strategies help organisation in different situation to develop appropriate competitive strategy that can be implemented effectively.

Competitive strategies are the methods and approaches used by companies to gain a competitive edge in the market and surpass their rivals. These strategies involve making deliberate choices about how to position the company, allocate resources, and respond to market conditions. Here are some key points to consider when introducing competitive strategies.

The sense organs in an insect body are distributed on different parts and respond to a given stimulus such as light, sound, touch, chemicals etc. The sense organs may be classified as • Visual organs (or) photoreceptors • Auditory organs (or) organs of hearing

• Chemoreceptors which respond to chemicals

• Tacticle receptors which respond to touch

• Gustatory receptors which respond to taste.

Photoreceptors

Light is perceived by insects through a number of different sense organs and these are the organs that react with light and useful for vision. These are of different types, but most important are the compound eyes.

Compound eyes

Goats and sheep play a vital role in natural farming systems due to their adaptability, efficient utilization of feed, and importance in sustaining rural livelihoods. Proper feed management is key to ensuring their health, reproductive success, and overall productivity, all while reducing reliance on external inputs. In natural farming, the diet of goats and sheep mainly consists of locally available grasses, shrubs, tree foliage, crop residues, and forage legumes. Fodder trees such as subabul, moringa, ber, and neem serve as valuable sources of protein and micronutrients. To address seasonal shortages, farmers establish fodder reserves and adopt agroforestry systems that combine tree planting with crop cultivation.
Goats, being browsers, thrive on a wide variety of vegetation including tough shrubs and woody plants, many of which contain medicinal secondary compounds. Sheep, on the other hand, prefer grazing on grasses and herbs, making careful pasture management essential to prevent nutrient deficiencies.
Locally sourced feed supplements like oilseed cakes, pulses, and leftover kitchen food help improve protein and energy intake. Mineral blocks enriched with salt, calcium, phosphorus, and trace minerals aid in proper skeletal development and reproductive health.

Abstract

Desert or arid regions present a unique environment for microbial growth. Thar Desert of India harbours a plethora of nitrogen fixing bacteria ranging from symbiotic nitrogen fixers, free living nitrogen fixers, associative nitrogen fixers and blue green algae or cyanobacteria. But the knowledge and extent of diversity is still limited to explore their full potential. On top of that, the documentation of the available knowledge is also scattered. Nitrogen-fixing bacteria are crucial for the protection of the nitrogen supply for vegetation in the arid region. Since deserts are poor in soil nitrogen, biological nitrogen fixation plays a crucial role in maintaining soil fertility. In this article, an attempt has been made to cover the nature and extent of diversity in nitrogen fixing bacteria in Indian arid zone.

Introduction

In agriculture, plant diseases have always been a major problem, as they cause crop quality to decrease, resulting in yield. Plant disease has a range of effects from minor symptoms to serious damages in whole crop areas, which lead to high financial costs and significantly impact the agricultural economy, particularly in developing countries dependent on a single crop or on a few crops.

Various approaches have been developed to detect disease in order to avoid significant losses. Causal agents have been precisely defined by methods developed in molecular biology and immunology. However, for many farmers these techniques are inaccessible and require detailed knowledge of the field or substantial time and energy to be used. According to the United Nations Food and Agriculture Organization, most farms in the world are small and family-owned in developed countries. Such families provide food for a significant proportion of the population of the planet. However, hunger and food insecurity are not rare and there is restricted access to markets and services. For the above reasons, a great deal of work has been undertaken in order to establish methods that are sufficiently reliable and available to most farmers. Where Plant disease is an essential factor contributing to a major decline in plant production quality and quantity. Plant disease identification and classification are a significant role in improving plant production and economic development.

Introduction

Clean and renewable energy is a basic requirement for developmental activities. Global energy crisis is caused by increasing world population, escalating demand due to urbanisation, and continued dependence on fossil-based fuels. Non-renewable energy sources like coal, natural gas oil contribute 79 per cent of world electricity generation; only 21 per cent comes from renewable energy sources. Promoting the use of existing renewable energy sources and identifying new environment-friendly technology is gaining importance. Switching to renewable energy sources like wind energy, ocean energy and solar energy is gaining a lot of importance. These green technologies emit less greenhouse gases into the atmosphere and hence are pollution free and immensely available. Recently, investigators have identified plants as weak energy sources. Plants are versatile organisms capable of communicating with each other with a number of signaling mechanisms. It was observed that plants generate electronic signals inside their system. The concept of utilising electronic signals for studying various physiological plant processes was first put forth by Sir Acharya J. C. Bose, an eminent biophysicist, botanist, archaeologist and polymath from India (Fromm and Lautner, 2007). His ideologies and concepts of movements of plants laid the foundation for modern electrophysiology-a branch of physiology that deals with electrical phenomena associated with metabolic functions. Attempts have been made to harvest electricity from free electrons available in plant leaves produced during photosynthesis and from rhizosphere of plants formed as a result of bacterial activity. Currently, a lot of attention is being given to improvise and develop this technology. To proceed forward in this direction, it is very critical to understand the mechanism of electrical signaling in plants.

Introduction to Corporate Level Strategy

Corporate level strategy pertains to the choices and initiatives undertaken by a company's senior management to define the overarching direction and breadth of the organization. It entails making decisions regarding which industries or markets to engage in and how to distribute resources among various business units.

Scope of Decision-Making: Corporate level strategy concentrates on the entirety of the organization rather than individual business units or functional areas. It involves strategic decisions related to diversification, vertical integration, mergers and acquisitions, strategic alliances & resource allocation.

Purpose: The primary goal of corporate level strategy is to create value for shareholders by achieving a sustainable competitive advantage and maximizing the overall performance and profitability of the organization. It involves assessing the external business environment, identifying opportunities and threats, and leveraging internal capabilities to gain a competitive edge.

Diversification: One key aspect of corporate level strategy is deciding whether to pursue a strategy of diversification. Diversification can be either related (expanding into industries or markets related to the company's current business) or unrelated (entering completely new industries). The decision to diversify involves assessing the potential benefits, risks, and synergies associated with entering new markets.

Soil is one of the major platforms on which life sustains. Soil, the product of weathering, covers the earth’s surface. Soil is the medium of plant growth and thus it requires proper attention for better crop yield. The land is the constituent of soil, vegetation, physico-chemical and biological attributes affecting its usages. The soil may act as a sink or source for the elements and other materials. Hence, it requires to understand the various components to facilitate management options for improving the fertility status of soil.

2.0 Soil

The soil is a natural dynamic body on which plant grows. It is a complex mixtures of minerals, water, air, organic matter and microorganisms. Besides, there exist an unconsolidated mineral or organic material on the surface of the earth and thus becomes a natural medium for the growth and nutrition of the plants.

During processing seeds are cleaned, dried, and graded which are then treated with specific fungicide and insecticide. Seed at this stage is at best quality, which are then packaged into various packaging materials in a specific weight. Packaging or bagging of processed and treated seed is a requisite for easy handling of the bulk seed. Seed packaging can be defined as filling with seed, weighing and sealing the container whereas seed package as storage container where the seeds are kept for marketing or shipping or till the next sowing time.

The Packaging of Seed Involves

1. Filling bags/ containers of uniform size with seeds of known weight.

2. Providing leaflets inside the package with information about any specific cultural practices needed.

3. Attaching labels or certification tags having information regarding all the quality parameters.

4. Temper-proof sealing of the bag.

5. Storage or transportation of the bags.

1. Introduction
Aquaculture, the farming of aquatic organisms, has grown rapidly over the past few decades to meet the rising global demand for seafood. As wild fish stocks continue to decline due to overfishing and environmental pressures, aquaculture is playing a crucial role in food production. However, like other forms of agriculture, aquaculture faces significant challenges, with feed management being one of the most critical. Feed represents the single largest operational cost in aquaculture, often accounting for 50-70% of the total production expenses. Efficient feed utilization is therefore central to the economic viability of aquaculture operations. Yet, traditional feeding methods are often inefficient, leading to feed wastage, nutrient pollution in water bodies, and suboptimal growth in farmed fish.
In conventional aquaculture, feed is typically dispensed at set intervals and in quantities based on estimations of fish appetite and growth requirements. However, this approach has several inherent inefficiencies. Overfeeding or underfeeding is common due to the lack of real-time monitoring and precision. Excess feed that remains uneaten sinks to the bottom of ponds or cages, decomposing and contributing to nutrient pollution. This not only represents a direct economic loss but also creates environmental problems such as eutrophication, which can lead to algal blooms, oxygen depletion, and poor water quality. On the other hand, underfeeding can result in stunted growth, poor health, and reduced productivity of fish. Both overfeeding and underfeeding, therefore, represent significant barriers to achieving sustainability and profitability in aquaculture.

The skin is the largest organ in the body. It not only defends the body but also assists in the maintenance of homeostasis including water conservation and in body temperature conservation through insulation and in heat loss through perspiration. Pain and temperature extremes are recognized through sensory nerves of the skin. The skin also provides protection against physical injuries to some level, supports hair growth and offers some defence against microbial invasion. Skin diseases are multifactorial in etiology. But the response of skin to varying etiological stimulus is limited leading to same clinical manifestations in different skin diseases. Therefore, a comprehensive clinical examination is necessary for accurate diagnosis of the disease. Clinical Examination The clinical examination of skin diseases involves a systemic approach including history, physical examination and diagnostic testing. History

Horticulture includes fruits, vegetables, floriculture, spices, tubers, plantation crops, medicinal and aromatic plants and mushrooms. The sector has established its importance in improving land use, promoting crop diversification, generating employment and above all providing nutritional security to the people. Even though India is the second largest producer of horticulture produces in the world, our per capita consumption of fruits and vegetables are very low.
