Internal Factors

The increased yield and other desirable characters are related to the genetic make up of the plant. They are :

• High yields under given environmental conditions.
• Early maturity (in some cases late maturity).
• Resistance to lodging.
• Drought, flood and salinity tolerance.
• Tolerance to insects and diseases.
• Chemical composition of grains (high percentage of oil, increase in protein quantity or quality, etc.)
• Quality of grains (fineness, coarseness, etc.)
• Quality of straw (sweetness, juiciness, etc.)

The urinary tract is the body’s drainage system. It includes kidneys, ureters, urinary bladder and urethra. Ultrasound is a most preferred imaging tool for the diagnosis of diseases of urinary tract not only in humans but also in dogs and cats. Little adipose tissue in urinary system of dogs makes the contrast between different planes and anatomical structures poor.

1. Introduction

There are around six hundred major and minor crop species but only two percent are cultivated commercially meeting the food (calorie) requirements. The most commonly cultivated food plants are even smaller counting to merely 20 crops (Wilkes, 1984). The huge number of underutilized crops may serve as potential fruit crops to meet the nutritional requirements of poor farming households in lesser common farming and subsistence agriculture. The adoption of underutilized crops on a commercial scale may not be possible without crop improvement, standardized agronomic and fertilizer management technologies, pre- and post-harvesting techniques and marketing (Bag Mal et al., 1997).

Introduction

Regenerative agriculture is both a philosophy and a strategy for land management. It asks us to consider how all aspects of agriculture are connected through a web, which is a network of entities that grow, enhance exchange, and distribute, consumer products and services. Traditionally, supply chains have been organized linearly. It is about farming and ranching in a way that nourishes people as well as the earth, with specific practices differing from grower to grower and from region to region. This style of farming and ranching is also known as “permaculture.” Although there is no definitive rule book, the holistic principles that underpin the dynamic system of regenerative agriculture are designed to address issues of inequity, reestablish the health of soil and ecosystems, and ensure that our land, waters, and climate are in better condition for future generations. It is a novel concept of uplifting the natural world rather than imposing an invasive control, regenerative agriculture intriguing environmental approach to agricultural production that enables the natural systems to renew themselves. Regenerative agriculture refers to farming practices that, in comparison to industrial agriculture, cause significantly less damage to the surrounding environment and the soil. When we give more to nature than what we receive from it, we bring nature closer to us and bring ourselves closer to nature at the same time. Farming that is in harmony with both the surrounding environment and the community fosters a feeling of integrity and togetherness that helps to strengthen the connection between the two. The concept of harmonious farming can be summed up in a few words: It involves engaging in agricultural practices and cropping systems that increase soil fertility return nutrients to the soil, increase soil water retention, remove carbon dioxide (CO2 ) from the atmosphere, and, most importantly, adapt to the ecosystems in which they are grown.

Various insect and mite pests infest fruit and plantation crops in different stages of crop growth directly or indirectly causing significant losses, hence need their management. The major pests of different fruit and plantation crops, their identification characters, life history, nature of damage and symptoms alongwith its management practices are described crop wise:

Temperate fruits

Pome fruits and stone and nut fruits are mainly cultivated in the temperate regions, which usually requires chilling requirements. Among stone and nut fruits cherry, apricot, peach and plum are the main crops whereas among the nut fruits, walnut, almond are major crops which are a source of handsome income to the orchardists of those areas. The insect and mite pests of pome, stone and nut fruits are described hereunder:

Sexual propagation through seeds is a fundamental method for producing horticultural crops, rootstocks, and planting material. This chapter explains seed structure, quality, viability, dormancy, germination, and factors affecting successful seedling establishment. Different types of seed dormancy and methods for overcoming dormancy are discussed, including scarification, stratification, chemical treatments, temperature management, and appropriate moisture conditions. Seed testing and quality considerations are important for obtaining uniform and healthy plants. The chapter also emphasizes the influence of temperature, oxygen, water, light, and substrate conditions on germination. Understanding seed biology enables students and growers to produce vigorous seedlings and establish reliable nursery and crop-production systems.

Carnation is one of the important cut flower crops grown throughout the world and occupies prime position because of the attractive colour, shape and good vase life. Due to the excellent keeping quality, wide range of forms, ability to withstand long distant transportation and remarkable ability to rehydrate after continuous shipping, carnation is preferred by growers to roses and chrysanthemums in several flower exporting countries.

Although cut carnations are sold in western countries all the year round, they are in particular demand for the Valentines Day, Easter, Mothers Day and Christmas. While standard carnations are in great demand, the miniature types are fast gaining popularity for their potential role in floral arrangement and also as cut flower at comparatively low price. White and pink standard carnations are in the greatest demand followed by red, yellow and bicolour. The liking for a colour depends upon the time or season. The re standard types are preferred to other colours, especially during the Christmas. In contrast in miniatures, the terminal flower bud is pinched to encourage clusters of short-stemmed small flowers. These types are mainly used for flower arrangement. (Bhatt, 1989)

Tamarind (Tamarindus indica) or Imli is also called  Indian Date. It is a large broad leaved, tropical tree found in India and many parts of Asia.  Tamarind is native to tropical Africa and grows wild throughout  Sudan. It was introduced to India so long ago that it is now reported as indigenous. Sometimes during  sixteenth century, it was introduced into America and today it is widely grown in Mexico.
 
There are large areas of marginal and waste lands, which are not suitable for cultivation of fruits like banana, citrus, sapota, litchi, mango, pomegranate etc., either due to poor quality of soil or lack of water resources. Such lands are suitable for  cultivation of underutilized fruit crops like tamarind which is not so popular among  farmers due to following reasons:

Introduction

The term “Integrated Farming System (IFS)” (or simply “integrated farming”) is a term used frequently and generically to describe a method of farming that is more integrated than monoculture methods. By virtue of the intensification of crops and related industries, an IFS offers the chance to enhance economic yield per unit area per unit time. This is accomplished through the system’s use of several crop rotations. It improves the efficiency of fertilizers and natural resources, improves the recycling of nutrients, and contributes to increased food security. The IFS technique promotes ecological intensification by lowering the amount of anthropogenic inputs while simultaneously enhancing the performance of ecosystem services such as the recycling of nutrients, the creation of soil, and the soil’s fertility. IFSs that are well- managed are seen to be safer than those that are not because they benefit from synergy among businesses, diversification of crops, and ecological stability (Behera et al., 2015). It requires paying attention to the minute details and constantly striving to improve in all facets of agricultural production through well- informed administrative practices. The IFS approach is widely regarded as the most important strategy for enhancing the nutritional status of families and ensuring the viability of their livelihoods. The research strategy that is centered on crops and cropping systems needs to give way to the research strategy that is based on agricultural systems, especially for smaller farms (Jha et al., 2011). Recycling of waste and increased effectiveness in terms of land utilization are two essential components of the IFS. The components and enterprises that make up the IFS might differ from region to region. This is because agroclimatic conditions, such as the kind of land, the availability of water, the socioeconomic standing of farmers, and market demand, all play a role. For effective holistic agricultural systems to be constructed, there must be strong connections and complementarities between the various components (Bell et al., 2014). Integrating land- based businesses into the biophysical and socio- economic contexts of farmers, such as aquaculture, poultry, duckeries, apiaries, as well as field and horticultural crops, is essential in the IFS to make farming highly profitable and reliable (Behera et al.,2004: Kashyap et al., 2015). Farmers who are limited in their access to resources can achieve sustainable output through the careful administration of agricultural residues and the distribution of limited resources

GENERAL CHARACTERISTICS OF FUNGI

1. Thallus

The body of the fungus is called as Thallus, which is without stem root and leaves. It maybe Plasmodial, Pseudoplasmodial , Pseudomycelial or Mycelial. A single thread like filament is called as hypha. A hypha is made up of a thin, transparent tabular wall filled or lined with a layer of protoplasm.

A group of hypha constituting the body of fungus is called as mycelium may be septate or aseptate. i.e coenocytic.

a) Coenocytic or Nonseptate or Aseptate Mycelium

When mycelium is not divided by cross walls called as Cornocytic mycelium.

Depending upon the nature of parasitism with the host plant, mycelium is either ecotophytic or endophytic.

b) Septate Mycelium

When mycelium is divided by cross walls or septa called as septate mycelium.

It is necessary to consider both micro and macro climate while planning scientific livestock management strategies. Thermal comfort of animals is the most important environmental consideration affecting the production performance of domestic animals in general and the dairy cattle in particular. Various components of climate like air temperature, humidity, solar radiation, wind velocity and precipitation affect the thermal comfort of animals and their performance. As these factors produce a combined effect rather than each component alone thermal indices involving two more of these factors are useful for rational decision making information for livestock managers. Considering only the direct effects of microclimate will be an over simplification of the problems because the indirect effects of the macroclimate operating through feed supplies, feed quality, parasitism, and other factors are equally or more important. These factors confound the direct effects of climatic elements and under many situations far overshadow their effects. Thus, evaluation of the direct and indirect effects of climate independent of each other is necessary. We will also examine each factor separately for easiness of understanding keeping in mind that the heat exchange of the animals with their environment is a combined effect of all these intertwined with complex biological and physical factors. Yamamoto (1983) concluded “Heat exchanges between animal and their environment are not readily explainable in terms of physical principles because the relationships are considerably modified by animal factors”. The combined effects of the climatic factors involved in heat exchange between any homoeothermic animal and its surrounding has led to the development of Thermal Indices as a basis for assessing the biological effect and consequent impact of thermal environment (Hahn 2003). Studies on the thermal environment and methods to represent in reliable indices are more important in the tropical world in general and hot tropical humid world in particular.

The advantages and disadvantages of thermal indices and how it can be used as useful guide for environment management of dairy cows are illustrated in this paper through examples. Many salient basic aspects were noted by Thomas C.K. way back in 1969 but the exact use of this information for the farmers is a far cry.

Introduction

The diversifi cation and modernization of the present agricultural and other related activities supported by efficient on and off farm processing of the commodities for the purpose of value-addition is expected to increase food production and create employment and income generation. Adding value to food commodities after harvest is also aimed at minimizing the losses during storage and to maintain the quality of product. Efficient post-production practices, particularly the preservation and processing of agricultural and allied produces may bring a wide range of benefits to the people in this country, generating job opportunities by opening up village-level processing units. The goals of post-harvest and food processing technology are loss prevention as well as adding value to the harvested biomass, which result in more income to the farmers/processors and better quality produce provided to the consumers. Post-harvest and food processing technology are commodity-and location-specific and it is done at home, village and/or cottage levels at small and large industrial scale. On-farm post-harvest storage and primary processing integrated with production technology help to generate more employment opportunities and additional income for rural people. Minimization of the post-harvest losses is an important means to increase per capita food availability. It also helps to generate more employment and income. Investment in post-harvest measures is more economical and time saving than in productivity to obtain the same amount of a particular commodity. Furthermore, post-harvest measures automatically add value to the raw commodities as they pass on their marketing channels. Adoption of postharvest technologies and value additive measures are very strong tools for rural and social development through employment and income generation. Development and adoption of efficient value addition practices will enhance national food supply and sustain food security even at the household level. Fruits and vegetables processing industries have a good deal of potential in serving the rural economy. First, it helps in generating more employment for rural people. It will also check mobility of rural masses towards urban areas in search of employment. Employment opportunities offered by agroprocessing industries are plenty to the farm population and entrepreneur seeking self-employment. Cottage scale units particularly offer self-employment opportunities. Traditionally women handle food and are familiar with skills of food processing. In order to improve the status of living of woman and rural food processing, low cost appropriate fruit and vegetable processing technologies offer excellent opportunities for production of processed foods. The improvement of status of socially backward and landless labor classes will be possible only through providing non-farm employment at their doorsteps. This will generate a sense of security and confidence amongst rural people for overcoming uncertainty in agricultural income and providing self-employment to the land-less labor. The locally available untapped resources should be used effectively.

Introduction

Digitalization is transforming the digital economy, offering opportunities for entrepreneurs and businesses, and transforming production and trade. The rapid advancement of technology and information systems has led to significant changes in both individuals and companies, particularly in the realm of digitalization in commerce (BarNir et al., 2003). Digitalization uses digital technologies to revolutionize business models, simplify transactions, and enhance value-producing opportunities in processes like customer service, shipping, buying, and selling (Zhang et al., 2013). All over the world, businesses are transitioning from manual to e-commerce for benefits such as efficiency, productivity, security, competitiveness, cost reduction, marketing, promotion, and information distribution (Daniel & Wilson, 2002; Gefen, 2000). E-commerce, a key feature, is reshaping global production and trade (Koh et al., 2017; Scalco, 2017). Moreover, the e-commerce industry has seen a substantial transition over the last few decades, due to rapid technical improvements and shifting customer behaviors.

In most countries there is no legislative definition of the term drawing a border line between conventional and functional foods is challenging even for nutrition and food experts. Functional foods do not have a specific place in food law; consequently there is a great deal of confusion about what they are, could or should be. A common perception is that functional foods are foodstuffs either with one or more specific added ingredients (components), or certain substances of common ingredients (components) removed and which are claimed to have a positive influence on human health or well being. The term ‘functional foods’ for this group of products is considered to be an unfortunate one since all foodstuffs are or should be functional and a more appropriate term might be helpful.

A same active ingredient are available in the market with different trade name and are the product of different companies. These may also differ in their formulation and hazard class (table 7), the knowledge of which is necessary in the plant disease management in view of their effect on the pathogen, ecosystem and environment.

6.1 Introduction

The World Health Organization (WHO) compiled a list of 20,000 medicinal plants used in different parts of the world. An estimated 15,000 medicinal plant species, forming about 21% of the total plant species used for medicinal purposes in the world, fall in the endangered category (Schippmann et al., 2006). In India, medicinal plant species used under different traditional systems to a large extent are still gathered and collected from the wild in from of roots, bark, wood, stem and even the whole plant causing severe destruction of their habitat, resulting in loss of species/populations and erosion of genetic diversity. The remaining few are cultivated as crop plants, but marginally because of lack of assured market and can be safely termed as commercially under utilized and are also under threat. Therefore, despite India being rich in plants species with medicinal properties, genetic diversity within the species and the associated traditional knowledge regarding their use, the lack of awareness regarding the loss of species and genetic diversity due to destructive harvesting from the wild and many other factors, such as infrastructure development, iintroduction of exotic species is causing depletion of genetic diversity or loss of indigenous MAPs.

Introduction

Chemical exposure in the workplace is a prevalent concern across various industries, including manufacturing, agriculture, healthcare, and construction. These exposures can range from acute to chronic and involve many substances, from heavy metals and solvents to pesticides and industrial chemicals. While the physical health effects of chemical exposure are well-documented, the psychological impacts are less understood but equally significant. Psychological stress is a response to perceived threats or challenges characterized by physical, emotional, and cognitive symptoms. Theories such as the Transactional Model of Stress and Coping by Lazarus and Folkman emphasize the role of individual perception and coping mechanisms in stress experiences.

The modern industrial landscape is characterized by ubiquitous chemicals, ranging from benign substances to potentially hazardous compounds. As industries strive for higher productivity and efficiency, the workforce is frequently exposed to various chemicals. This exposure is not without consequences; while the physical health effects of chemical exposure have been extensively studied, the psychological impacts are less understood. Emerging research indicates that chemical exposure can significantly contribute to psychological stress, affecting worker health, productivity, and overall well being.

Climate normals for crops and livestock refer to the long-term average weather conditions, such as temperature, precipitation, and humidity that are suitable for specific crops and livestock in a particular region. These normals help farmers and agricultural planners understand the typical climate conditions that support optimal growth, productivity, and health of crops and livestock. By knowing the climate normals, farmers can make informed decisions about:
• Crop selection and breeding
• Planting and harvesting schedules
• Livestock management and breeding
• Irrigation and water management
• Pest and disease management
15.0. Crop Weather Calendars
A Crop Weather Calendar (CWC) is a valuable agrometeorological tool used to align the crop growth stages with prevailing weather conditions to optimize agricultural practices. It helps farmers, extension workers, and planners make informed decisions by integrating weather information with the crop‘s physiological needs (Fig. 15.1).

Precision agriculture includes information driven administration choices that further develop asset use productivity, bringing about decreased Agriculture expenses while bringing down the natural effects from agriculture. Consequently, information and information assortment frameworks, choice help devices, and information driven hardware and info changes are significant parts of Precision agriculture, participating in three vital farming advances: determination, direction, and performing separately. Before the coordination of shrewd innovations, ICT (data and correspondence innovation) was incorporated into farming devices and mechanical assembly to get certifiable data. Here, remote detecting, mechanized hardware and programming, telemetric, drones, autonomous vehicles, GPSs, and computerized developments were incorporated into cultivating rehearses. For example, the agro-tech association John Deere introduced GPSs for ranch farm haulers, anticipating extended yield and reduced input wastage. The previous status of accuracy agribusiness before brilliant cultivating can be summarized as follows.
Data Collection and Acquisition
Data, data collection, and decision support devices are critical for the distinctive verification and finish of alternate points of view in cultivating. In Accuracy agribusiness, data on individual fields and gathers are collected by seeing, assessing, and distinguishing with different sorts of sensors, yield and soil checking, and remote-detecting mechanical assemblies, such as imaging from drones, groups, airplane, or satellites. As such, “detecting” is a fundamental organization gadget of accuracy agribusiness, which is seeing distinct information and giving data on climatic circumstances, soil conditions, fertilizer necessities, water openness, nuisance and infection stresses, and other field limits. An extent of sensors is used in Accuracy farming. Biomass limits are huge in making decisions to screen the readiness and truly zeroing in on crops. Sensors for mass stream and dampness content are portions of yield screens, along with a differential global positioning system (DGPS) recipient. Appropriately aligned yield screens can produce precise constant
