22.1  Introduction

Plant pests have been part of man’s environment for a long time. Traditional agriculture, which included diverse crops and indigenous crop management practices, provided little opportunity for pests to build up and spread rapidly (Smith and Allen, 1954). Crop production is constantly threatened by increasing difficulties in controlling insect pests, which are a major impediment to improved livelihoods of poor farmers. However, in the quest to increase food production for the growing population, use of pesticides became a norm in crop management. Pesticides became an integral part of the process owing to losses from weeds, diseases and pests reducing the harvestable produce. Use of pesticides along with high yielding varieties, irrigation and improved seed did result in increased productivity. But the rampant use of these chemicals, under the adage, ‘if little is good, a lot more will be better’ has played havoc with human and other life forms.

1. FLOWERING

The flowering goes through a phase of vegetative growth producing more stems and leaves and a flowering phase where they produce the organs for sexual reproduction.

1.1. Synchronisation in flowering

Synchronous flowering refers to the phenomenon of coincident, simultaneous flowering of all population of a given species in a large region.

The research setting is an important component of the research methodology. Research setting refers to the detailed information of an area where the study was conducted. The research setting can be seen as the physical, social, and cultural site in which the researcher conducts the study. In qualitative research, the participants are observed in their natural environments with a primary focus on meaning-making. The study area generally consists of a particular geographical area viz. a state, district, block, or gram panchayat area selected according to the benefit of the investigator who possesses adequate knowledge regarding the location, communication facility, the period of study, the availability of resources, etc. of the locality so that he can easily approach every corner of the area for data collection. Additionally, to comprehend people’s knowledge, attitudes, and behaviour more easily, investigators must have a fundamental understanding of their socio-demographic backgrounds. It is the environment within which studies are run that has important consequences for experimental design, the type of data that can be collected and the interpretation of results.

Common Exotic and Indian Dog Breeds

India is home to a rich diversity of dog breeds both indigenous and exotic, each with unique traits suited to different environments and lifestyles. Among the exotic dog breeds that have gained popularity in India are the Labrador retriever, Golden Retriever, Beagle and German shepherd. These breeds often imported and are known for their friendly nature, intelligence and trainability. Labradors and Golden Retrievers are particularly famous for their loyalty and gentleness, making them excellent family pets. The Beagle, with its keen sense of smell and compact size, is a favourite among urban dwellers, while the German shepherd is valued for its protective instincts and versatility in roles like police work, guard duties and service tasks.

In contrast, Indian dog breeds, many of which are lesser-known globally, are uniquely adapted to the country's diverse climate and conditions. The Indian Pariah Dog is one of the oldest and most resilient breeds, found naturally across the country. Known for its strong immune system, minimal grooming needs and intelligence, the Indian Pariah is an exceptional companion that thrives with minimal human intervention. Another indigenous breed is the Rajapalayam, a sighthound from Tamil Nadu, historically used for hunting boar and protecting livestock. With its striking white coat and regal demeanour, the Rajapalayam is revered for its loyalty and bravery. The Mudhol Hound/ Caravan Hound, from the Deccan Plateau region (Andhra Pradesh, Karnataka, Maharashtra, Telangana and Tamil Nadu of India), is another notable Indian breed, known for its speed, agility and endurance, often used in hunting and guarding. Chippiparai, another hound from Tamil Nadu, has a sleek body designed for speed and was historically favoured by royalty for hunting small game. The Kanni, also native to Tamil Nadu, is a close relative of the Chippiparai and is recognized for its grace and loyalty, often kept as a companion dog.

Medicinal Plants for Arsenic Toxicity
Name of the Condition- Nephrotoxicity
About the condition/Definition- Intoxication of arsenic (arsenite or arsenate) result in renal impairment which is marked by a significant increase in the levels of creatinine, urea, uric acid and decline in levels of plasma protein profile especially albumin level in body.
Etiology- Nephrotoxicity results from arsenic damages mitochondria, which results in the excessive production of reactive oxygen species (ROS), a decline in ATP, and a suppression of respiratory activities along with dramatic alterations in the incidence of cellular growth. There is acute inflammation and the development of tubular necrosis, which lowers the glomerular filtration rate (GFR).
Symptoms- Phosphaturia (Fanconi syndrome), aminoaciduria, proteinuria and glycosuria along with progressive drop of renal function.
Pathogenesis- Arsenic produces renal damage by reducing mitochondrial complex function and elevating cellular ROS levels which directly damages renal cells. Membrane lipid peroxidation and protein oxidation by ROS, which results in complete loss of membrane potential and mitochondrial swelling.
General treatment- Acute arsenic intoxication can be counter by using chelating agents like DMSA, DMPS and BAL, fluid therapy, forced dieresis & dialysis.

Abstract

Temperate ornamental plants, owing to their special functions, are always in great demand due to their possible uses in temperate landscape plantings (both outdoor and indoor). This ever increasing demand has led to urgent need for their mass-scale multiplication on commercial scale. At present, most of these plants are being multiplied and supplied on a limited scale by concerned Government and private agencies but this is not sufficient. Progressive orchardists of temperate zone and particularly those inhabiting marginal lands which no longer yield regular income, can specially incorporate the element of commercial floriculture in the vacant places in their orchards or through establishment of small polyhouses. Introduction, multiplication and production on large scale of commercially important ornamental trees, shrubs, climbers, bulbous plants, herbaceous perennials, cut flowers, potted plants and seed production of important annuals and perennials by the progressive orchardists in their orchard will yield fruitful returns through their sale and will narrow the constant demand for these plants in the urban and rural areas and will definitely improve the fragile ecology of the hills in the long run. The interested orchardists can collect germplasm of these plants from various Govt. and private agencies. Such an intervention in the existing orchard cropping system will definitely increase the income of the farmers from the same available area and will be a right step towards diversification.

INTRODUCTION

Pulses are edible fruits or seeds of food bearing plants belonging to the family of the leguminosae. The major pulses which find important place in our diet are redgram dhal, bengal gram dhal, black gram dhal, green gram dhal and masoor dhal. Some are used as whole grams cow pea, rajmah and dry peas also belong to leguminous family.

Legumes not only have dietary values but also play an important role in maintaining or even improving soil fertility through their ability to fix atomospheric nitrogen.

Zinnia is a very important summer annual belongs to family Compositae. Zinnia was named for the man who wrote the first scientific description of the flower, “Dr. Johann Gottfried Zinn” a German Professor of medicine, but it was the late 19^th century that plant breeders started to pay any attention to this plant. Zinnia is a half hardy plant. They are popular for bedding however, cut flowers of zinnia remain fresh for several days. They are easy to grow from seeds. Collection of open pollinated seeds is in common practice in India. Non-uniformity of bloom with respect to colour, flower shape and size, height of the plants and excessive etiolation of the plants result into poor sale of zinnias.

ORIGIN AND DISTRIBUTION

The genus Zinnia consists of 20 species, all native to the New World (Bailey, 1951). Further Stemart and Thomas (2007) suggested that zinnia are native to scrub and dry grassland in an area stretching from the Southwestern United States to South America, with a centre of diversity in Mexico.

Zinnias are grown mostly as annual in Mexico, Texas, New Mexico, Colorado, Brazil and Chile. It is sometimes called the Mexican marigold as its designation in some degree is justified in case of the yellow varieties. In early days zinnias were not popular. Although native to North and South America, not everyone found them attractive or desirable as a landscape plant. In fact, when Spanish first saw the zinnia species in Mexico, they considered the flower so unattractive that they named it “mal de ojos” which is Spanish for “Sickness of eye”. Zinnia seeds brought back to Europe in eighteenth century caused little excitement although the plant did not get good name. But it was not until the late nineteenth century that plant breeders started to pay any attention to this species.

The start of real popularity of the zinnia came around 1920 when Bodger Seeds Ltd. introduced the dahlia flowers Giant Dahlia. John Bodger discovered it as a natural mutation in a field of Mammoth and within the next few years selected the California Giant (large, flat-flowered variety) from the strain. The most attractive feature was availability of flowers in different colours. It also was considered to be a new trend in plant habit and flower form. It even won a gold medal from the Royal Horticultural Society of England, making everyone want to grow this prize winning flower. The many garden form of Zinnia elegans developed from the wild plant that grown in Mexico. Common zinnia has escaped and naturalized in part of southern United States including central Florida. Recently cultivation of new hybrid zinnias have started in some American and European countries under open as well as protected conditions for cut flower production.

Introduction

High density planting in fruit trees was first introduced in case of apple in Europe during the nineteen sixties, with the development of Malling and Malling - Merton rootstocks. Subsequently, this was experimented in other temperate fruit crops like peach, plum, pear and sweet cherry. Today, majority of new orchards of apple and to some extent that of other fruit crops in Europe, New Zealand, USA and Australia use this intensive system of fruit production profitably Iyer and Kurian (2006). The successful management of trees in any high-density planting system depends on maintaining a balance between vegetative growth and fruiting.

Under natural habitats microorganisms usually grow in mixed populations containing several species. This is really a problem for microbiologists because a single type of microorganism can not be studied adequately in a mixed culture. In laboratories these populations can be separated into pure cultures. The pure cultures contain only one type of organism and are thus suitable for studying the cultural, morphological and biochemical characters of an individual species. In the present days there are several ways of developing pure cultures in laboratories. Some of which are as follows:

Agricultural project is an investment activity in which financial resources are expended to create capital assets that produce benefits over an extended period of time. Projects are the building blocks of investment plan. The whole complex of activities in the undertaking that uses resources to gain benefits constitutes the agricultural project.

Introduction

The cultivation of flowering and attractive plants is referred to as floriculture, sometimes known as flower farming. Even though flowers have long been planted in India for a variety of purposes, including aesthetic, social, and religious purposes, the commercial floriculture sector is a relatively recent development.

The industry of floriculture has a great deal of untapped potential and has quickly become an essential part of modern life. The floriculture industry has developed into a business that is run for profit, has achieved significant market value, and is poised to realise favourable prospects. In India, the cultivation of blooming plants, including garden plants, cut flowers, foliage plants, potted flowering plants, and other types of blooming plants, is referred to as f loriculture. In today's world, flowering or ornamental plants are frequently used as part of several celebrations' decorations or as presents due to their versatility. They are also used as vital raw materials in the sectors of perfume, pharmaceuticals, and oil extraction. So, to start a floriculture firm in India, it is necessary to comprehend how agribusiness is used in its marketing and production.

ABSTRACT

Grewia asiatica L. locally called ’Phalsa’ (Family Tiliaceae) is a multipurpose gregarious plants species native to Asian belts, grows profusely in tropical and subtropical forests. Plant yield berries rich in calories, proteins, carbohydrates, dietary fibers, vitamins, macro-and micro-nutrients such as calcium, phosphorus and sodium. Their parts can be used as herbal medicine for treatment of various diseases. Recently, CSIR-Indian Institute of Integrative Medicine Jammu (IIIM) has developed and released a variety of this plant for rural upliftment and for development of value-added products such health drink and nutraceuticals. From its matured fruits of cultivated variety, a value added product called Shivalik Health Drink was developed by IIIM. For extension, agrotechnology of this plant has been transferred to various geographic regions of India such as Punjab, Rajasthan, Jammu & Kashmir, Uttar Pradesh, Maharashtra and Andhra Pradesh. This species prefers hardy and can be able to withstand in drought environment. For development of drugs and value added products, several therapeutic research works have been carried out which suggested that this plant species possess antioxidant, antidiabetic, antimicrobial, hepatoprotective, antifertility, antifungal, analgesic and antiviral activities. Further, there is a need to focus on biotechnological intervention with aim to develop seedless varieties and new nutraceutical products.

18.1 INTRODUCTION

Organic farming systems have attracted increasing attention over the last one decade because they are perceived to offer some solutions to the problems currently besetting the agricultural sector. In the western world, organic farming is catching fast (Malik, 2000). Indiscrimpte use of chemical fertilizers, herbicides and pesticides have resulted in environmental and health hazards along with socio-economic problems (Padmadevi, et al., 2008). India is bestowed with lot of potential to produce all varieties of organic products due to its diverse agro-climatic regions. In several parts of the country, the inherited tradition of organic farming is an added advantage. Organic farming is necessary to attain the goal of sustainable development. According to the Food and Agriculture Organization (FAO), sustainable agriculture “is the successful management of resources for agriculture to satisfy changing human needs while maintaining or enhancing the quality of environment and conserving natural resources”. All definitions of sustainable agriculture lay great emphasis on maintaining an agriculture growth rate, which can meet the demand for food of all living things without draining the basic resources. Organic farming is one of the several approaches found to meet the objectives of sustainable agriculture. Many techniques used in organic farming like intercropping, mulching and integration of crops and livestock are not alien to various agriculture systems including the traditional agriculture practised in countries like India. However, organic farming is based on various laws and certification programmes, which prohibit the use of almost all synthetic inputs, treated seeds and health of the soil is recognized as the central theme of the method. Adverse effects of modern agricultural practices on the farm resources and health and over all survival of living being have been well documented all over the world. Application of technology, particularly in terms of the use of chemical fertilizers and pesticides has been serious concern. Their negative effects on the environment are manifested through soil erosion, water shortages, salination, soil contamination, genetic erosion, etc. Organic farming has the potential to provide benefits in terms of environmental protection, conservation of non-renewable resources and improved food quality. It is very important to maintain long term soil biological activity, ensure effective peak management, recycle wastes to return nutrients to the land, provide attentive care for farm animals and handle the agricultural products without the use of extraneous synthetic additives or processing in accordance with largely acceptable standard and applicable standards of destination country/ countries. Organic farming has several advantages over the conventional one apart, from the protection of both the environment and human health. Improved soil fertility, better water quality, prevention of soil erosion, generation of rural employment, etc. are some of them.

Indira Awaas Yojana (IAY)

Indira Awaas Yojana, which used to be a component of Jawahar Rozgar Yojana became an independent Scheme from 1997-1998 onwards. Its objective is construction of free houses to members of the Scheduled Castes/ Scheduled Tribes, Freed Bonded Labourers in Rural areas and also to non SC/ST rural poor living below poverty line. The beneficiaries are selected from the Below Poverty Line (BPL) list approved by the Grama Sabha. Atleast 60% of the total IAY allocation during a financial year should be utilized for construction/ upgradation of dwelling units for SC/ST BPL rural households. A maximum 40% of allocation is for non- SC/ST BPL rural households. 3% of the above categories should be allocated for physically and mentally challenged persons. 

1. Introduction

The technology is a part of dynamic environment which has brought a lot of change in styles and pattern of various fields. Out of this education is also one of the integral parts. Technology has brought immeasurable effect in the f ield of education. E-learning consists of various types of facilities such as audio and images delivers text animation etc. E-learning process involves many types of local networks or the internet basis learning. E-learning has made learning and developmental activities so frequent which leads to easy access to required information. E-learning is a way of creating knowledge and circulating the same where teacher plays a vital role. The basic objective of e-learning is exploring and adding essential knowledge.

Introduction

Fungicides are those chemical substances which helps to prevent or kill the growth of fungal spores. Fungicides play a vital role in floriculture, safeguarding ornamental plants from devastating fungal diseases. These diseases, such as leaf spots, blights, root rots and powdery mildew, can significantly diminish the aesthetic and economic value of flowers. Fungicides are indispensable in f loriculture, ensuring the health and beauty of flowers from seedlings to full bloom. They not only protect plants from debilitating diseases but also support the economic viability of flower production. By integrating fungicides with other management practices, floriculturists can achieve a balanced approach that maintains plant health, preserves environmental quality and promotes sustainable production practices. This balanced approach is crucial for the long-term success and sustainability of the floriculture industry. Integrated Pest Management (IPM) practices in floriculture often incorporate fungicides as part of a comprehensive strategy to control fungal diseases. Fungicides, available in various formulations like sprays, dusts and systemic treatments, function by either inhibiting fungal growth or eradicating the fungi entirely. Some fungicides are absorbed by plants, providing extended protection, whereas some fungicides offer immediate, albeit shorter-term relief.

Introduction

The floodplain wetlands or beels are used as multiple use and multiple users system. The large numbers of the stakeholders participate in the beels both within fisheries and across other sectors like forestry, animal husbandry, agriculture, flood control etc. (Sugunan & Sinha 2001, Ramsar Convention Secretariat 2004). The different set of stakeholders constitutes a diverse set of interests, goals and priorities for the fisheries. Therefore, under the present context, the fisheries managers face an extremely complex situation in governing fisheries of the wetlands. Such complexities lead to sub-optimal or unwise use of the wetlands. There is growing concern over the depletion of resources, poor quality of aquatic environment, poor potential realization, poor fisheries management, inequities, conflicts, over exploitation etc of the beels (CIFRI 2000, Pomeroy & William 1994, Welcomme & Bartley 1998). These issues are the outcome of the complex fisheries exploitation system and research efforts are being made to find suitable management regimes to address such issues. The evaluation of outcomes, identification of the shortcomings and understanding decision making process have been an important researchable areas (Pomeroy & William 1994, ICLARM & NSC 1998). Evaluation of a system should include depiction of its goals or objectives and an assessment of how well they are met as well as obstacles faced in meeting them. Accordingly, it is important to identify the management context of the beel fisheries management viz., the formal goals of a fishery management regime; the formal or informal goals of the various actors within it; the processes by which goals are identified and contested; processes through which they are linked to other aspects of the regime- including knowledge production and the implementation of action measures (ICES 2000). Therefore, it is imperative to understand the objectives, decision making process and criteria for evaluation of the fisheries management of the wetlands as a step towards further research in designing effective management regimes. The paper attempts to delineate the system in the simplistic way as well as review the relevant literature to map the objectives, decision making arrangements and evaluation criteria for assessing the fisheries management regimes of the beels. The present paper has been made based on the experience and understanding developed in the context of the beel fisheries management of Assam.
