Abstract

Accurate forecasting of the rice yields is very important for the organization to make a better planning and decision making. The aim of the study is to investigate the ability of neural network for yield prediction of rice in Andaman and Nicobar Islands. Field experiments were conducted at the various regions of Andaman and Nicobar Islands during 1980 to 2002 and data collected was subjected to Artificial Neural Networks (ANN) approach for developing a meaningful yield prediction for four varieties of rice C14-8, Quing Livan No.1, Taichung , Sen Yu, Jaya under island conditions with the objective to estimate the crop production a few days or months before harvesting of crop. The observations of all experiments viz., Varietal spectrum, Weather parameters , Yield components, Soil, Abiotic stressors, Biotic stressors for the period of twenty years from 1980 to 2002 were collected from the basic records of experimental field. All the data were used for training data set. Prediction of crop yield, mainly strategic plant of rice has been an interesting research area to agronomists since long for its importance in national and international economic programming. Application of ANN was found to be significant tool for prediction of yield in rice.

INTRODUCTION

Marigold is an important flower crop and constitute as one of the five most commonly cultivated and used flower in urban and rural India. They are extensively used for making garlands, beautification and other purposes i.e. pigment and oil extraction and thera eutic uses A art from these uses marigold is a widely grown plant in gardens and pots. It is highly suitable as a bedding plant, in a herbaceous border and is also ideal for newly planted shrubberies to provide colour and fill the space. French marigold is most ideal for rockery, edging, hanging baskets and window boxes. Flowers remain fresh for 4-5 days at room temperature and are used for religious offerings and social functions. Recently marigolds are grown commercially for extraction of carotene pigments mainly xanthophylls. The carotenoid extracted from petals are added to poultry feed for intensification of yellow colour of egg yolk. Lutein which is the major constituent of xanthophylls is used for colouring food stuffs. Purified extract of marigold petals containing lutein dipalmitate is marketed as an ophthalmologic agent under the name adaptinol. Dietary carotenoids can be used to treat cancer and photosensitivity diseases.

Marigold leaves contain a distinct odoriferous oil. Wild marigold (Tagetes minuta) oil has valuable and precious essential oil which is used in high grade perfumes and cosmetics. Ketones present in the oil are base material for synthesizing aroma chemicals. Marigold essential oil has bronchodilatory, tranquilizing, anit-inflammatory as well as insect repellent activities. The floral extract of marigold is used for treating eye diseases and ulcers.

Fermentation is one of the ancient techniques that been routinely used to maintain the quality of food products. This process involves the breakdown of complex substances like carbohydrates into smaller ones which assist in extending the shelf life of food products. Fermented foods and beverages shared the major portion of the human diet which positively affect the body. Beer is a low alcoholic drink in which malt, hops and other adjuncts like aromatic herbs, honey and others are fermented with yeast to obtain a product that offers unique flavour, taste and aroma (Sohrabvandi et al., 2012).

Learning outcome

The purpose is to enable the student to develop deeper knowledge understanding capabilities and attitudes in the context of group discussion.

What is the group?

A social group is a unit of two or more person in the reciprocal interaction of communication with each other.

Stages of Group Formation

Bruce Tuckman presented a model of five stages.

Orientation (Forming Stage)

During this stage, group members come together and begin to establish relationships with each other. They also clarify their goals and objectives for the group.

Power Struggle (Storming Stage)

As the group begins to work together, conflicts and differences in opinions may arise. This stage is characterized by power struggles, disagreements, and a lack of cohesion among group members.

Cooperation and Integration (Norming Stage)

In this stage, the group begins to resolve conflicts and work towards a common goal. Members begin to cooperate with each other, establish norms and rules, and develop a sense of unity.

The intricate dance between climate and agriculture has been a longstanding relationship, with the former playing a pivotal role in shaping the latter. Nowhere is this more pronounced than in the choices rural households make regarding cropping systems and farming practices. The climate, with its multifaceted influences, acts as a silent decision-maker, guiding the selection of crops, farming techniques, and ultimately, the livelihoods of those who toil on the land. For rural households, the choice of cropping system and farming practices is not merely an economic or technological decision; it is deeply intertwined with the environmental context in which they operate. Climate variability and change introduce a layer of complexity, necessitating adaptations that can make or break the resilience of these households. The decision-making process is influenced by a range of climate-related factors, including temperature fluctuations, precipitation patterns, and the frequency of extreme weather events. This chapter aims to explore the nuanced relationship between climate and the agricultural choices made by rural households. By examining the impact of climate on cropping systems and farming practices, we can gain a deeper understanding of the adaptations and strategies employed by these households to mitigate risks and capitalize on opportunities. The discussion will encompass the various ways in which climate influences decision-making, from the selection of drought-resistant crop varieties to the adoption of conservation agriculture practices. Through a detailed analysis of the interplay between climate, cropping systems, and farming practices, this chapter seeks to provide insights into the complex dynamics at play. By doing so, it aims to contribute to a better understanding of how rural households can be supported in their efforts to adapt to a changing climate, ensuring the sustainability of their agricultural practices and the resilience of their livelihoods.

Abstract

Spices are aromatic substances of plant origin which are commonly used for flavouring, seasoning and imparting aroma in foodstuffs. They are cultivated in an area of 5.98 million ha globally with a total production of 7.31 million tons. India is considered as the home of majority of these spices from ancient times and sizable area of the country is under spice cultivation. The latest statistics shows that the total cultivated area in India under spices is 2.89 million ha with a total production of 3.33 million tonnes. About 109 plants belonging to 31 families are recognized as spices useful as ingredients in food. Many of them have been demonstrated to mediate therapeutic benefits for wide spectra of diseases ranging from multiple sclerosis to colorectal cancer.

Introduction

Advances in molecular genetics in the last 20 years like rapid DNA amplification techniques using PCR, rapid sequencing methods and computational software programs have enabled the placement of molecular markers on to the maps of chromosomes of most major crop species and the subsequent tagging of genes of interest by their placement near those markers^[38]. Unfortunately very little or scanty molecular data of spices are available in the public domain (Table 12.1). ‘Orphan crops’ like spices which have not yet received the investment of research effort or funding can exploit comparative genomics and bioinformatics to assist research and crop improvement provided they are related to a well-characterized model plant species.

Introduction

Flowers are associated with mankind since the dawn of civilization. Flowers are required for all the functions, ceremonies, rituals and celebrations from dawn to the dusk. In India, flowers are mainly grown for cut flowers and loose flowers purpose. By using best postharvest techniques, we can preserve the flowers ranging from few days to few weeks, but drying or dehydration is a technique by which flowers can be preserved for months to years. India has rich biodiversity comprising of wide variety of ornamental trees, shrubs, climbers, etc. which are not being used as fresh or loose flowers but their branched, twigs, flowers, fruits, cones, stems, roots, bark, etc. can be dehydrated to preserve their beauty and for utilization in dry flower industry.

The role of bioinformatics in genomics and molecular biology research can be likened to the role of intelligence gathering in battlefield. Intelligence is clearly very important in leading to a victory in the battlefield. Computational algorithms are the heart of bioinformatics as they enable predictions, understanding and interpretation of the data generated from laboratory experimental research carried by biologist. This article discusses one such approach called Decision tree induction and its application for generating rules from a dataset extracted from biological databases.

Decision Tree (DT) is one of the most popular choices for learning from feature based examples. They are especially attractive in data mining environment for several reasons. First due to their intuitive representation, the resulting classification model is easy to assimilate by humans. Second, DT does not require any parameter setting from the user and thus are especially suited for exploratory knowledge discovery. Third DT can be constructed relatively fast and accuracy of DT is comparable or superior to other classification models.

Abstract

The arid Kachchh district, located at the western most part of the Gujarat State in India, is known for its large extent of area under wetland habitat, which is represented by numerous seasonal water bodies and coastal habitats. Vast stretch of grasslands also available in the northern border of the district, the Banni (23⁰ 19’ to 23⁰ 52’ N; 68⁰ 56’ to 70⁰ 32’ E), which encompasses an area of 2,617 km². There are many depressions in Banni, locally known as Dhandh (shallow lakes). During monsoon, rainwater gets collected in these depressions and form shallow lakes. About 34 smaller and bigger size Dhandhs are present in the Banni. Banni communities are highly dependent on the Dhandhs for various purposes. Due to the erratic rainfall in arid Kachchh, Maldharis is highly unstable for livestock in search of fodder and water during drought years. During the normal rainfall years, livestock from neighboring talukas of Kachhh and even from other districts depends on this grassland and Dhandhs. During last decade, the Banni grasslands have seen serious environmental changes due to the invasion of an exotic plant Prosopis juliflora and increasing the salinity are the major issues of Dhandh degradation. Thus, the Banni is gradually losing its capacity to sustain human and livestock population.

Main objectives of the present paper is to examine the local perceptions of wetland and grassland change, socio-economic status, and factors that cause degradation of the wetland and vegetation resources in the Banni grassland.

Abstract

World Economic forum (WEF) which evaluated 149 countries on four parameters including economic participation and opportunity, educational attainment, health and survival, and political empowerment, said that it would take 108 years to close the overall gender gap. That means the economic opportunity gap-based on participation, pay and advancement in the workforce-remains the area that is going to take the longest time to close. Globally, women are paid less than men. Women in most countries earn on average only 60 to 75 per cent of men’s wages. Contributing factors include the fact that women are more likely to be wage workers and unpaid family workers; that women are more likely to engage in low-productivity activities and to work in the informal sector, with less mobility to the formal sector than men. India’s inequality crisis hurts girls and women the most. An Oxfam report on inequality published in January 2019 revealed that in the workplace, women still receive 34% less wages than their male counterparts for the same work. In J&K, incidences of domestic violence, dowry, etc are rampant. State Women Commission J&K receives 1600-1700 domestic violence cases every year, majority cases being from the Kashmir Valley. Men’s silence, insensitivity and indifferences with regards to gender equality practices need to be the focus theme of the time. The fight for gender equality cannot be fought by women alone. Men have a key role to play in demanding and supporting this societal shift by being a part of the movement.

Keywords: Women empowerment, global perspectives, Indian perspectives, way forward.

8.1. Comparative advantage principle

Different areas or regions or farmers will tend to produce those products for which they have greatest comparative and not just absolute advantage.

Due to an extension and application of principles of specialization and diversification.

Each farm or region produces those crops or raises that livestock which it can grow more profitably

For example, farmers in Tamil Nadu specialize in sugarcane cultivation and those in Punjab specialize in paddy cultivation.

Introduction

Plants are considered as immobile organisms with poor sensitivity and limited ability to respond. Within the plant kingdom, Mimosa pudica (also called the sensitive plant), Drosera (sundews), Dionea muscipula (flytraps) and tendrils of climbing plants which showed rapid and purposeful movements were considered as exceptions. These sensitive plants attracted attention of outstanding pioneer researchers like Pfeffer (1845-1920), Burdon-Sanderson (1828-1905), Darwin (1809-1882), Haberlandt (1854-1945) and Bose (1858-1937). Stahlberg, 2006 reported the presence of various mechanoreceptors in such species which could trigger action potentials (APs) which activated these sudden movements.

The first extracellular recording of a plant action potential (AP) development was initiated by Charles Darwin; later, the animal physiologist Burdon-Sanderson in 1873 performed similar studies on leaves of the Venus flytrap (Dionea muscipula Ellis). Haberlandt (1884) demonstrated that phloem strands were the actual paths for excitation by destroying the external, non-woody part of vascular bundles. This notion was confirmed in Mimosa and other plant species by a number of recent studies. Houwink (1935) carried out experiments with two species of Vitis (grape) and obtained electrical fluctuations which was similar and comparable with the action potentials he obtained with Mimosa. In 1907, Bose, used a D’arsonval galvanometer to demonstrate propagating electrical effects in different genera of plants such as Ficus, Artocarpus, Cucurbita, Corchorus, “fern” etc. APs have their largest amplitude in phloem sieve cells and cells adjacent to this area (Sibaoka, 1969). Other studies found that AP-like signals are propagated with equal rate and amplitude throughout the cells of vascular bundles.

Introduction to Corporate Governance

Corporate governance encompasses the framework of rules, practices, and processes that guide the direction, control, and management of a company. It involves the interactions among various stakeholders, including shareholders, management, the board of directors, employees, customers, suppliers, and the community. Successful corporate governance is vital for a company's long term success and sustainability. It helps establish a framework for responsible decision-making, accountability, and transparency, which enhances investor confidence and protects the interests of stakeholders.

1. Introduction
Aquaculture, the farming of aquatic organisms such as fish, shellfish, and aquatic plants, has become one of the fastest-growing food production sectors globally. This growth has been driven by the increasing demand for high-quality protein to feed a growing global population, coupled with the depletion of wild fish stocks due to overfishing. As the aquaculture industry expands, so too does the need for sustainable practices that balance productivity with environmental and animal welfare considerations. One of the critical challenges faced by modern aquaculture is the need to maintain fish health and growth performance while minimizing the industry’s ecological footprint. Traditionally, synthetic additives such as antibiotics, chemical growth promoters, and other artificial substances have been used to improve fish health, enhance growth rates, and prevent disease outbreaks. However, the excessive use of these chemicals has led to several issues, including antibiotic resistance, chemical residues in fish products, and environmental pollution. These concerns have spurred a shift toward more sustainable, eco-friendly alternatives in aquaculture production systems.
In this context, phytogenics—natural, plant-based additives—have garnered increasing interest as a promising solution. Phytogenics are bioactive compounds extracted from various plant sources, including herbs, spices, and essential oils, that possess multiple beneficial properties. These compounds have been used in traditional medicine and animal husbandry for centuries due to their antimicrobial, antioxidant, anti-inflammatory, and immunomodulatory effects. By leveraging the natural bioactive compounds in plants, phytogenics offer a range of advantages for aquaculture, including enhanced growth performance, improved feed efficiency, strengthened immune responses, and reduced disease susceptibility. The need for sustainable and natural alternatives to synthetic additives is becoming more urgent as the global consumer base becomes more health-conscious and environmentally aware. Consumers today increasingly demand seafood products that are free from chemical additives

Agricultural meteorology, the study of the interactions between the atmosphere and agricultural systems, has long been a crucial aspect of farming and food production. As the global population continues to grow, increasing pressure on agricultural systems to produce more food, fiber, and fuel while minimizing environmental impacts, the importance of agricultural meteorology will only continue to intensify. Operational agricultural meteorology, in particular, focuses on the practical application of meteorological knowledge to support decisionmaking in agricultural industries. This chapter introduces a systems analysis approach to operational agricultural meteorology, providing a comprehensive framework for understanding the complex relationships between weather, climate, and agricultural systems.
11.1. The Need for a Systems Analysis Approach
Agricultural systems are inherently complex, involving numerous interactions between biotic and abiotic factors, such as soil, water, plants, animals, and the atmosphere. The complexity of these systems makes it challenging to understand and predict the impacts of weather and climate variability on agricultural productivity and sustainability. Traditional approaches to agricultural meteorology often focus on specific aspects of the system, such as crop yields or soil moisture, without considering the broader system dynamics. A systems analysis approach, on the other hand, recognizes the interconnectedness of these components and seeks to understand the system as a whole.
11.1.1. Key Components of a Systems Analysis Approach
A systems analysis approach (Fig. 11.1) to operational agricultural meteorology involves several key components:
• System Boundaries: Defining the boundaries of the agricultural system, including the spatial and temporal scales of interest.
• System Components: Identifying the key components of the system, such as crops, soil, water, and atmosphere, and their interactions.
• Feedback Loops: Recognizing the feedback loops within the system, where changes in one component influence other components.
• System Dynamics: Understanding the dynamic behavior of the system, including the flows of energy, water, and nutrients.

This chapter introduces the principles involved in designing and erecting protected structures for floricultural production. It examines structural safety, dead and live loads, wind and snow loads, site selection, orientation, foundation, greenhouse components and suitable covering materials. The chapter also identifies flower and foliage crops suitable for protected cultivation and relates structural design to crop characteristics and climatic conditions. These principles help growers develop efficient, safe and productive greenhouse systems

Abstract

The study of palm genomics can aid to understand the genetic and molecular knowhow of all biological processes in palms that are vital tothe palm species. This knowledge will allow the path for the fruitful exploitation of palms as biological resources in the development of new cultivars of improved quality and with shortened economic and environmental costs. This knowledge is also vital for the development of new diagnostic tools. Traits considered of primary interest are resistance to pathogens and abiotic stress, fruit quality and yield. Genomics and bioinformatics approaches helped in unraveling the genomes of economicpalsm like coconut, oilpalm and datepalm. The genome characteristics and tools for genome analysis are provided in the chapter. Due to the economic importance of cocoa, many scientific research studies (genome, EST, transcriptome) have been carried out in the past years in this crop also.

Introduction

Plantation crops constitute a large group of crops. The major plantation crops include coconut, arecanut, oil palm, cashew, tea, coffee and rubber; and the minor plantation crops include cocoa (Prapulla and Indira, 2014). India is the third largest producer of coconut and goes in front of the ninety coconut-producing countries of the world (Richard 2013). India is the largest producer and consumer of cashew nuts (Mohod et al., 2011.). India also occupies number one position in arecanut production (Dwivedi et al.,2008) besides being the largest tea producers in the world. While Coffee is the second largest traded commodity in the world, it has, in recent times become an extremely important foreign exchange (Prapulla and Indira, 2014).

1. Herbicide –herbicide interaction

Herbicides cause some effects as follow:

(i) Synergistic: Synergism is defined as the cooperative action of different chemicals in a mixture such that the total effect is greater than the sum of the independent effects (Green et al., 1997). In relation to herbicides, the total  induced by an herbicide mixture is greater than the sum of the responses by each herbicide alone (Anderson, 1996). Synergistic  is often used to describe the effect of drugs working together — where one drug increases the other’s effectiveness. Synergy is the interaction of multiple elements in a system to produce an effect different from or greater than the sum of their individual effects.

All the states have some area under irrigation. Thus the term ‘irrigated ecosystem’is rather loosely defined, and the states having distinctly large net irrigated area may constitute this ecosystem. Two such areas can be easily carved out i.e., Indo-Gangetic Plain region representing five states namely Punjab, Haryana, U.P., Bihar and West Bengal, and coastal areas of two southern states i.e., A.P and Tamil Nadu. About 56% of the net irrigated area of the country exists in these states, and the cropping intensity is also much higher (144%) as against national average of 132%. With demographic viewpoint also, these areas are densely populated. Of late agriculture in this ecosystem has become unsustainable owing to over-exploitation of natural resources. Studies have conclusively established the superiority and worth of integrated nutrient management in restoration of soil health and sustenance of crop productivity and profits.

The basic concept underlying the principles of integrated nutrient management (INM) is the maintenance, and possibly improvement, of soil fertility for sustaining crop productivity on long-term basis. This may be achieved through combined use of all possible sources of nutrients and their scientific management for optimum growth, yield and quality of different crops and cropping systems. INM is not a new concept, but an age-old practice. Its importance was, however, not realized earlier due to low nutrient turn over in soil-plant system and almost all the nutrient needs were met through organic sources, which supplied secondary and micronutrients also besides major nutrients. INM has now assumed great significance mainly because of two reasons. First, the need for continued increase in agricultural production based on increase in per hectare yields requires growing application of nutrients, and the present level of fertiliser production in india is not enough to meet the total plant nutrient requirement. Second, the results of a large number of experiments on manures and fertilisers conducted in india and other countries reveal that neither the chemical fertilisers alone nor the organic sources exclusively can achieve the production sustainability under intensive cropping systems (Hegde and Dwivedi, 1993). Even the so called balanced use of chemical fertilisers would not be able to sustain high productivity due to emergence ofthe deficiencyofone ormore ofthe secondaryandmicronutrients (Swarup and Wanjari, 2000). The interactive advantages of combining organic and inorganic sources of nutrients in INM have proved superior to the use of its each component separately. The advantages of INM can be broadly enumerated as following:

Present day hydrogeomorphological research is the explanation of landscape and landforms: what they are, how they function and have developed with reference to the hydrological conditions. Research is a much more complex undertaking than giving names to landforms or even the study of processes, both in terms of what we mean by process and how explanations are approached. It is worthwhile examining some reasons for this, as it shows the increasing complexity of the subject and lead to ideas of how hydrogeomorphology can be studied. Here are some of the fundamentals required for hydrogeomorphological studies:

Mechanism and Processes

‘Mechanism’ provides explanations in detail by describing physical or chemical effects. ‘Process’ signifies the integration of mechanisms in time. Thus, for example when we talk about ‘fluvial process’ or, more specifically, about the ‘mechanism of saltation’, then we have to discuss about the energy source and processes of carrying the material. A process can thus be viewed as the simultaneous operation of a set of specific mechanisms over a specific time period.
