Systematic management of plant diseases dates back to 1885 with the invent of Bordeaux mixture by Milardet. Thereafter, a number of contact and systemic fungicides have been reported over the years for the management of various plant pathogens, of which many have become obsolete and many are still being used with excellence. However, the ecological hazards caused by the chemical fungicides have prompted scientists to search for other avenues of crop protection. Most of the conventional chemical and biological plant protection procedures, as well as the use of disease-resistant cultivars, tend towards the direct control of pests and diseases by their elimination. But these practices generally and particularly in case of monoculture crops like rice, raise problems. The risk of developing pesticide resistance in plant pathogens is enhanced by the long term use of the same chemical. The resistance genes of the plants can also be overcome by changes in the pathogens. Therefore the situation demands development of new strategies for plant protection which can supplement the use of resistance breeding and chemical control.

ABSTRACT

Chhattisgarh is a tribal dominating state and is one of the backward and poor area of India in terms of poverty and productivity. The trees have been the part of agriculture in this region since long. The present paper highlights some of the practices which are being adopted by the farmers from time immoral and efforts had been made to fit them in the present day scientific classification system of agroforestry system with their spatial and temporal sequences. Despite of the fact that trees are integral part of farmlands still adoption of agroforestry as a sustainable land use has some constrains which have been discussed and way out suggested. Areas needed in developing agroforestry in the state have also been discussed at the end of the chapter.

All over the world, garden designing has a historical back ground. Every continent has a definite style based on cultural heritage, agro-climate and the rulers. There are influences of one style over the other and subsequent change in gardening style also. However, there are some recognized orthodox styles like ‘English Garden’, ‘French Garden’, ‘Japanese Garden’, ‘Italian Garden’, ‘Dutch Garden’, ‘Mughal Garden’ etc. These are unique and true to their specific characters. Modern gardens all over the world have been greatly influenced by all these styles.

History and characteristics of these gardens are given below in order to make one acquainted with these styles.

Dutch Garden

Initially, gardening in The Netherlands was started in the form of abbey and monastery gardens (middle ages 500-1500 A.D.). Design of the medieval gardens usually was elongated rectangle, sometimes square, also divided with cross paths. These gardens were mainly meant for production of vegetables, medicinal herbs and fruits besides flowers.

During the Dutch renaissance (1500-1650 A.D.) further gardening activities initiated. After independence in 1609, it gained momentum and the change of garden style also noticed. Gardens became more open without walls. However, the basic design was on the basis of geometrical patterns - rectangular divided into small separate square. Axis of the garden was not in relation to the building. Leafy walk path (berceaux) was main structural elements created between various sub-divisions. Bulbous plants specially tulip was most preferred in the garden besides marigold, carnation, poppy, rose etc.

Abstract

Chitin has been ranked at second position after cellulose as the most abundant natural biopolymer. Chitin has similar chemical structure to that of cellulose with 2-acetamido-2-deoxy-b-d-glucose (NAG) monomers attached via ß (1–>4) linkages. Chitosan is the deacetylated (to varying degrees) form of chitin, which, unlike chitin, is soluble in acidic solutions. Therefore, Chitosan, a copolymer of glucosamine and N-acetyl glucosamine, is amongst the most copious biopolymers on earth and finds wide range of biomedical and industrial applications. It has been approved in 1983 by USDA as a feed additive. Chitin basically is obtained from prawn/crab shells and chemical treatment of chitin produces chitosan. Since supplies of seafood waste are seasonable and variable, so fungi can be used as alternative source for chitosan. The unique physicochemical properties of chitosan provide great potential of its utilization in food industry especially dairy industry such as production of dairy products, dairy waste water treatment, extension of shelf life of dairy products etc. In recent years, exotic synthetic compounds are losing their appeal, thus application of chitinous products in dairy as well as processing aids has received considerable attention. The modified chitosan with greater functional properties has increased application in different dairy foods. This chapter focuses on the fundamental uses of chitosan and their derivatives in a variety of dairy industry applications.

Seed quality is the possession of seed that is genetically pure and physically homogeneous, coupled with health and wellness.

A seed is the first genetic material that becomes the basis for future agriculture and seeds are the basic building blocks of agriculture. A great deal of farming has been modernized by technology, but without a regular and steady supply of high quality seed, yields would be drastically reduced and crop quality would decrease as well. The production of horticultural and agronomic crops depends largely on quality seed. For farmers, seed characteristics such as genetic purity, germination percentage, vigor, and appearance have a significant effect on yield. Every professional seed producer strives to achieve and maintain high seed quality.

8.1 Disease Prevention and Control in Aquaculture

Aquaculture, the farming of aquatic organisms such as fish, shellfish, and plants, faces significant challenges related to disease management. Diseases in aquaculture can result from viral, bacterial, fungal, or parasitic pathogens, and their outbreaks can lead to substantial economic losses and environmental impacts. Effective disease prevention and control strategies are crucial to sustainably manage aquaculture operations and ensure the health and welfare of cultured species.

Key Strategies for Disease Prevention and Control

1. Biosecurity Measures

Biosecurity is foundational in preventing the introduction and spread of diseases within aquaculture facilities. It involves a set of management practices aimed at minimizing the risk of pathogen transmission through various pathways:

• Quarantine Protocols: New stocks should undergo quarantine periods before introduction to production systems. This allows for health screening and observation to detect and isolate potentially diseased individuals.

Introduction

Raising milk and meat production are long-standing global issues. Researchers are learning that present breeding efforts won't be sufficient to meet anticipated future food demands given the current climate scenario. The animals that influence the overall yield of the field must be screened as soon as possible. In order to build more successful modern breeding programmes, high-throughput phenotyping is currently being included into conventional breeding operations. Despite the public accessibility of their genetic information online, there is still a lack of phenotypic data on the genomes of various animal breeds because environmental factors make it more difficult to define phenotypes and increase the likelihood of measurement error (Rahaman et al., 2015). Genomic selection (GS) is a strategy that predicts the genomic estimated breeding values of lines in a breeding population using information from genome-wide markers (Meuwissen et al., 2001). When compared to other conventional methods like marker-assisted selection (MAS), genomic selection has some inherent advantages. These include boosting genetic gain by reducing breeding cycles and acquiring minor effect loci based on markers dispersed throughout the entire target genome. Reliable phenotypes and genotyping are both necessary for the training of accurate prediction models for genomic selection. Phenotyping is regarded as a significant factor restricting genetic improvements in animal breeding due to high labour and time expenditures. Traditional approaches of phenotyping are prohibitively expensive, time-consuming, and slow.

The typical way of living that reflects one’s attitude and values is called lifestyle of the person. A person’s lifestyle is shaped by one's specific geographic, economic, political, cultural and religious context. A lifestyle is a means of forging a sense of self and to create cultural symbols that resonate with the personal identity. According to WHO lifestyle is “a specific type of behaviour that can reduce disease and early death by personal physical, mental and social interaction”.
Lifestyle refers to the interests, opinions, behaviors and orientations of an individual, group or culture. The term was introduced by Austrian psychologist Alfred Adler in his 1929 book, The Case of Miss R., where he described it as “a person’s basic character established early in childhood.” Since 1961, the broader sense of lifestyle as a “way or style of living” has been recognized. Lifestyle is influenced by both tangible and intangible factors. Tangible factors include demographic variables, such as an individual’s demographic profile, while intangible factors involve psychological aspects like personal values, preferences and outlooks.
Lifestyles vary significantly between rural and urban environments. Even within urban areas, the nature of the neighborhood affects the lifestyles available to residents, influenced by factors like affluence and proximity to natural and cultural environments. For instance, coastal areas often have a surf culture or lifestyle. A lifestyle typically reflects an individual’s attitudes, way of life, values or worldview. It serves as a means of forging a sense of self and creating cultural symbols that resonate with personal identity. However, not all aspects of a lifestyle are voluntary. Social and technical systems can limit the lifestyle choices available to individuals and the symbols they can project to others and themselves.

Abstract

Deduction of overindulgence fluoride (F)  from the water has been endeavor by numerous investigators by using different materials both natural and artificial. The objective of this paper was to attempt the fluoride removal by using the locally available natural materials such as red soil, untreated charcoal, local powdered brick, fly-ash from Neyveli (thermal power plant) and mineral serpentine were used, adopting column method. Maximum defluoridation occurs immediately after the experiment has started. The morality of fluoride removed per gram is more in red soil when compared to the other materials. Variation of fluoride removal with time was studied after the erection of the column /unit, the defluoridation setup was then connected to the public water supply from the overhead tank of 50,000L capacity. Higher F removal was noted when flow rate was lesser. An attempt on the regeneration of the fluoride adsorbed soil was also made.

Abstract
 
Much attention has been paid to mycorrhza as a tool for improving the growth and health of plants.  The use of mycorrhiza in agricultureal, horticultural and forestry has been described. The significance of AM fungi in sustainable agriculture has been a subject of growing interest for the past several decades. In sustainable agriculture it is imperative to maximize benefits with low input costs. The fact remains that stable and lower human population is an integral component of sustainable agriculture and more so in an Indian context. Therefore, it is imperative to collect further information on the different aspects of AM fungal symbiosis as discussed in this article so as to utilize this plant microbe symbiotic system for the increased production and productivity in a sustainable manner. This may become possible when the integrated approach is made to study AM fungi right from the isolation of AM fungal spores to the high quality inoculum production and its application in the field. It is also imperative to stimulate new mutualism between mycorrhizal scientists and ecologists. It this regard, recent advancement made in the molecular techniques should be encouraged in order to obtain more authentic results. Adequate field testing of mycorrhizal inoculation and commercial exploitation of the potential benefits of mycorrhiza still rests on the development of suitable technology for mycorrhizal inoculum preparation.

Introduction

In India ,the increasing demographic pressure with developmental activities are causing tremendous pressure in utilization of natural resources leading to various kinds of ecological problems and land degradation. The Govt. of India has for long considers watersheds as catalysts for development activities in rain-fed areas. Watershed, simple stated as a manageable hydrological unit. Watershed development approach calls for an integrated effort of many courts, viz, area development, resource identification and management programme- planning, implementation and evaluation and also the disciplines and functionary involved. An integrated approach in watershed management, the development of agricultural land alone is not the criteria, but the development of the entire area covering a watershed from highest point (ridgeline) to outlet of the Nalah or natural stream will have to be considered.  For scientific development of watershed area, all natural resources such as water, land, human, vegetation, livestock, wildlife etc. have to properly identified, quantified, and appropriately utilized.

In its original concept, vaccination aims to mimic the development of naturally acquired immunity by inoculation of nonpathogenic but still immunogenic components of the pathogen in question, or closely related organisms. The term “vaccine” (from the Latin term “vacca,” meaning cow) was first coined by Edward Jenner to describe the inoculation of humans with the cowpox virus to confer protection against the related human smallpox virus and illustrates the close relationship between human and animal infectious disease sciences. The famous proverb saying ‘Prevention is better than cure’ implies perfectly to the vaccines. Vaccines have proven to be boon for animals which can be regard a potential weapons against infectious diseases caused mainly by bacteria and viruses. The major aims of veterinary vaccines are to improve the health and welfare of companion animals, increase production of livestock in a cost-effective manner, and prevent animal-to-human transmission from both domestic animals and wildlife. Vaccines have long been used to combat infectious disease; however the last decade has witnessed a revolution in the approach to vaccine design and development. Apart from improving animal health and productivity, veterinary vaccines have a significant impact on public health through reductions in the use of veterinary pharmaceuticals and hormones and their residues in the human food chain.

Brucellosis, one of the most ancient diseases, continues to be a problem for humans and animals throughout the world causing enormous economic losses and significant human morbidity in endemic areas. The bacterial pathogen is classified by the CDC as a category B pathogen that has the potential for development as a bioweapon. It is one of the important zoonotic disease and considered as the most common laboratory acquired pathogen with >5 lakh human cases reported annually around the world. Brucellosis is a chronic infection which can result in infertility, delayed heat, interrupted lactation, loss of calves, wool, meat and milk production in animals and undulant fever in humans. Although in most of the counties, brucellosis is a nationally notifiable disease and reportable to the local health authority, it is underreported and official numbers constitute only a fraction of true incidence of the disease. Although the true incidence of human brucellosis is unknown, the estimated burden of the disease varies widely from <0.03 to >160 per 1 lakh population. Although only 17 countries in the world are free from the disease, it has been reported in many countries including India. Bovine brucellosis is endemic in all the states in India and appears to be on the increase in recent time, perhaps due to increased trade and rapid movement of livestock. The preponderance of natural bull service in rural India is perhaps yet another important factor in the maintenance and spread of infection. The Government of India has made it mandatory to regularly screen all the breeding bulls from artificial insemination centres, for brucellosis and to use brucellosis free bulls for semen production.

Etiology: Brucella sp. are facultative intracellular Gram - ve coccobacilli, nonspore forming and non-capsulated. It infects macrophages with principal involvement of liver, spleen and bone marrow. Nine Brucella species are currently recognized, seven of them that affect terrestrial animals are: B. abortus, B. melitensis, B. suis, B. ovis, B. canis, B. neotomae and B. microti and two that affect marine mammals are B. ceti and B. pinnipedialis. The first three species are called classical Brucella and within these species seven biovars are recognized for B. abortus, three for B. melitensis and five for B. suis. The remaining species have not been differentiated into biovars.

3.1. Introduction

Food preservation can be defined as the science which deals with the process of prevention of decay or spoilage of food thus allowing it to be stored in a safe condition for future use. Scientifically, preservation may be defined as a science which deals with the process for prevention of decay. All foods gradually undergo deterioration or spoilage from the time they are harvested or manufactured. Some commodities spoil rapidly, while others can keep for longer but limited periods. Spoilage in the food products may be caused due to some physical, chemical and microbial changes during storage. The preservation of these products can be resulted by controlling following physical, chemical and microbial changes.

Agriculture has long served as the backbone of human civilization, enabling societies to grow and prosper. For generations, farmers have relied on experience, traditional practices, and historical weather data to inform decisions about crop cultivation and livestock management. Yet these conventional methods often left operations vulnerable to unpredictable environmental conditions. Today, the integration of the Internet of Things (IoT) is transforming agriculture by shifting the approach from reactive management to proactive, data-driven decision making. Modern IoT systems deploy a network of interconnected sensors that continuously capture critical environmental parameters such as soil moisture, temperature, humidity, light intensity, and nutrient levels. These sensors provide granular, real-time data that is transmitted to centralized analytics platforms where it can be processed and visualized. The resulting insights empower farmers, aquaculturists, and animal husbandry professionals to optimize every aspect of their operations — enhancing yields, reducing waste, and increasing sustainability. This chapter explores the deployment and impact of IoT in agricultural and allied systems. It provides detailed technical discussions on sensor networks, communication protocols, and power management; illustrates how real-time data integration with advanced analytics transforms decision making; and presents in-depth case studies from initiatives such as John Deere’s precision agriculture systems, Microsoft FarmBeats, and regional projects like SmartAgriHubs. Moreover, the chapter delves into the formidable challenges of IoT deployment, including those faced by underdeveloped regions—and concludes with a look at emerging trends and a synthesis of the future vision for agriculture.
6.1 The Role of IoT in Modern Agriculture
6.1.1 Revolutionizing Data Collection
The most significant impact of IoT in agriculture is its transformation of data collection. Traditional methods relied on periodic field observations, manual sampling, and regional weather reports that provided only a snapshot of environmental conditions. In contrast, IoT devices continuously monitor the microclimate across a farm. With sensors distributed throughout fields, livestock facilities, and aquaculture systems, farmers can now capture real-time data on temperature, humidity, soil moisture, light intensity, and more (Fig.6.1).

To many Bio Fertilizer is still an unclear term. Often they are identified as urban and rural organic wastes, plant extracts, organic components etc. However, Bio Fertilizer is mostly commonly referred to the use of soil micro organisms to increase the uptake and availability of plant nutrients. Bio Fertilizer have gained a good deal of momentum and the industry after a slow start is now gaining more and more importance globally. The major reasons for this are that they:
1. Improves the soil structure.
2. Add nutrients to the soil / make the nutrients available to the crop
3. Secret certain growth promoting substances
4. Under certain conditions exhibit antifungal activities and there by protect the plants from pathogenic fungus
5. Enhances seed germination
6. Increase the soil fertility
7. Increase the agricultural productivity
8. The nitrogen fixed or phosphate solubilized will be beneficial to the
subsequent crops also.
The major, popularly used and commercially produced Bio Fertilizers are Nitrogen fixing bacterial fertilizers (Azotobacter Culture, Azospirillum Culture, Rhizobium Culture) and Phosphate solubilizing bacterial fertilizers (Pseudomonas Culture). However, currently their applications for other useful elements like Potash, Sulphur, Zincetc are also increasing.

Introduction

Intellectual property rights form the most prominent and ever-expanding category of rights in the 21^st Century. It differs from other proprietary rights in many respects and prevails in most articles of law, which influence our daily life. The economic significance of intellectual property rights has made it a subject of global political interest. In the broader sense, the term “intellectual property rights” connotes different categories of rights such as patents, copyrights, trademarks, designs, plant varieties, semiconductors, geographical indications, trade secrets and data exclusivity with varying scope
