Abstract

Horticulture crops play significant role in improving the productivity of land, generating employment, enhancing exports, improving economic conditions of the farmers and entrepreneurs and providing food and nutritional security to the people. For better management of the existing crops and to bring more area under horticulture crops, updated and accurate database is necessary for systematic planning and decision making. Remote sensing (RS) is an advanced tool that aids in gathering and updating information to develop scientific management plans. Many types of sensors namely microwave radiometers, laser meters, magnetic sensors and cameras collect electromagnetic information to derive accurate, large-scale information about the Earth’s surface and atmosphere. Because these data and images are digital, they can easily be quantified and manipulated using computers. RS can be used in efforts to reduce the risk and minimize damage. The same data can be analyzed in different ways for different applications. A number of studies were aiming at identification of crop, area estimation, disease and pest identification, etc. using satellite data in horticulture. The potential use of RS techniques in Horticulture is briefly reviewed in orde

The fore limb is termed as pectoral limb or thoracic limb (Fig. 5-1). It is attached to the thorax by means of muscles of pectoral girdle (shoulder girdle). It is composed of four major segments, the shoulder girdle, arm, forearm and manus. The skeleton of shoulder girdle is formed by the shoulder bone, the scapula. The arm is formed by the arm bone the humerus. The forearm is formed by two bones the radius and ulna; and the manus is formed by the carpus consisting of six short bones –the carpal bones arranged in two layers, the metacarpus consisting of one large and one small metacarpal bones and the digits consisting of six short bones the phalanges and six small sesamoids arranged in two rows for each limb.

Shoulder girdle

The shoulder girdle (thoracic girdle or pectoral girdle) in general is composed of the scapula, coracoid and clavicle. In ruminants the scapula is well developed, the coracoid is in the form of a small rounded process fused with the ventral end of the scapula and the clavicle is absent or in some subjects it occurs embedded in the brachiocephalicus muscle cranial to the point of the shoulder. But this possibility is very rare. Hence, in ox only scapula is considered as the bone of shoulder girdle.

Scapula

The scapula is a flat triangular bone applied obliquely ventrad and craniad against the cranial part of the lateral wall of thorax. Its long axis extends from the fourth thoracic spine to the sternal end of the first rib. It presents two surfaces, three borders and three angles.

Plant Propagation

Plant propagation involves the formation and development of new individuals, which are used in establishment of new plantings. It is simply the reproduction or multiplication of a plant from a source that is often referred to as a mother plant. In general, two methods are employed: 1) sexual and 2) asexual. Sexual propagation is multiplication of plants from seed and asexual or vegetative propagation involves starting a new plant from some vegetative part of a plant. Propagation by seed results in seedling variability. It is an extreme disadvantage for a nursery operator trying to produce a uniform crop containing chosen desirable characteristics. Seed propagation is not practiced in fruit nursery as plants raised by this method fail to bear true to type fruits.

Germination of seed

The activation of the metabolic machinery of the embryo leading to the emergence of a new seeding plant is known as germination. Germination is essentially a quickening of the growth of the embryo. As germination proceeds, the growing points of the radical and plumule divide rather rapidly Usually the radical emerges from the seed coat first, proceeds downward, and develops into the root system, the plumule proceeds upward and develops into the shoot system. Germination is entirely a food utilization process. Processes going on in seed during germination are: 1) Absorption of water; 2) Secretion of enzymes and hormones; 3) Hydrolysis of stored food into soluble form; and 4) Translocation of soluble foods and hormones to the growing points. These processes are either wholly or in part influenced by the food reserves, hormone supply, water supply, oxygen supply and temperature level.

The genetically engineered (GE) seeds developed using recombinant DNA technology often referred to as transgenics or genetically modified organism (GMOs) provide an usually adaptable, scale neutral technology for the farmers. Even small farmers can benefit from such seeds provided the seeds are made available at reasonable cost. While growing such seeds the existing crop management practices are usually sufficient. The transgenics or GMOs are also defined as those organisms with a gene or gene construct of interest that has been introduced by molecular or recombinant DNA techniques. These exclude organisms produced by conventional breeding as well as organism produced by rearrangement of genetic materials by physical methods or by chemical means. Thus, GMO’s carry trangene(s) which when integrated and expressed stably and properly, confer either a new trait to the organism which was hitherto not present (such as insect resistance), or enhance an already existing trait such as nutritional quality (Prasana 2001).

Abstract

The term “Horticulture” is a part of agriculture system which is concerned with the raising of so called garden crops. At present, fruits, vegetables, flowers etc., are grown not only within the backyards, but also in large areas in open fields on a commercial scale where better visualization can be viewed with GIS. It emerged by calculating the present context which allows us to produce a complex view about the land’s characteristics. Most of the GIS in use today have not been designed to support multimedia data and therefore have very limited capability due to the large data volumes, very rich semantics and very different modelling and processing requirements. Use of Remote Sensing (RS) and GIS in natural resource and environmental monitoring has been advocated strongly in present years. The present review gives an idea about the basic concepts of GIS, its components and applications in the agricultural sector particularly horticulture. GIS has been extensively and successfully exploited in various areas using various software’s which are available in current market.

India is blessed with wide range of diverse agro climatic conditions, making it an appropriate place for vegetable cultivation, resulting in increasing vegetable production from has increased from 63.8 MT in 1993 to 168.5 million tonnes in 2015-16 and productivity from 12.6 MT/ha to 17.8 MT/ha (www.indiastat.com). Although the production has increased but still the technology used and practices followed is predominantly traditional resulting in low productivity and inconsistent quality and quantity of produce supplies to various markets in the country. The per capita consumption of vegetables in India is very low against WHO standards and FAO recommendation (135 g/day <180 g/day (WHO standards) < 300 g/ day capita (FAO recommendation).

Abstract

Rheological properties of dough from different flours are very important to know about the kneading and modeling process especially for development of bakery products. Rheological testing is helpful to examine the structural and fundamental properties of dough. The basic principle underlying evaluation of rheological properties are mechanical behavior of the dough, in conjunction with the physical structure of the dough, the molecular structure of the protein continuous phase in the dough and with chemical reactions of functional groups. This chapter presents some of the methods currently used in bakery industry for determining the rheological characteristics of the flour and the dough. The instruments such as Farinograph, Mixograph, Extensigraph, Alveograph and Amylograph, which are used for the measurement of dough rheological properties (due to visco-elastic behavior of dough) were described.

Cotton is a major crop of India grown in about 9.0 million hectares.This is the largest cotton area in the world. Thus, India ranks Ist among cotton growing countries in the world in terms of area. However, average cotton yields in India have been 320 kg/ha as compared to world cotton yield average of 580 kg/ha. Thus, cotton production in India represents only about 13% of the total world production whereas India accounts for approximately 20% of the world’s total cotton area. Obviously, yield levels in India are low compared to world average. The low yield levels in India are partly due to heavy losses from insect pests, particularly cotton bollworm complex.

Introduction

In many developing countries including India, agricultural sector is of vital importance to the economy and welfare of the inhabitants. Agriculture contributes to 14% of the Indian GDP and supports the livelihood of two-thirds of the population. Despite tremendous technological developments, vagaries of weather continue to plague the agriculture production. Any shortfall in agricultural production will have its cascading effect on the economy of the country. In recent times, climate change and variability are confounding the troubles already faced by Indian agriculture and the farming community. Loss in crop production and farm income due to unexpected weather hazards is beyond the carrying capacity of resource poor farmers of the country. With the growing commercialization of agriculture, the magnitude of crop loss due to unfavourable weather hazards is increasing leading to suicides of farmers. The State and National governments on their part are coming to rescue of farming community by implementing various relief measures like reduction or suspension of land revenue taxes, loan waiving, relief from calamity relief fund etc. Though these measures are helpful, farmers cannot expect them as a right and they put lot of burden on the country’s exchequer.

1. Introduction

If we want to know what kind of plants and animals are in a particular habitat, and how many they are of each species, it is obviously (usually) impossible to go and count each and every one present. It would be like trying to count different sizes and colors of grains of sand on the beach. This problem is usually solved by taking a number of samples from around the habitat, making the necessary assumption that these samples are representative of the habitat in general. In order to be reasonably sure that the results from the samples do represent the habitat as closely as possible, careful planning beforehand is essential.

The usual sampling unit is a quadrat. Quadrats normally consist of a square frame, the most frequently used size being 20×20 m² for trees, 5×5 m² for shrubs, 1×1 m² for herbs. The purpose of using a quadrat is to enable comparable samples to be obtained from areas of consistent size and shape. Rectangular quadrats and even circular quadrats have been used in some surveys. It does not really matter what shape of quadrat is used, provided it is a standard sampling unit and its shape and measurements are stated in any write-up. It may however be better to stick to the traditional square frame unless there are very good reasons, because this yields data that are more readily comparable to other published research. (For instance, you cannot compare data obtained using a circular quadrat, with data obtained using a square quadrat. The difference in shape of the sampling units will introduce variations in the results obtained.)

Blockchain technology has emerged as a revolutionary solution in various industries, and agriculture is no exception. By providing a secure and transparent system for recording and verifying transactions, blockchain has the potential to transform the agricultural sector. In this chapter, we will explore the role of blockchain in agriculture, its benefits, and various use cases that demonstrate its potential. Additionally, we will present key statistics and real- world examples to illustrate the impact of blockchain in agriculture.

Introduction Feed is a major source of nutrition in semi-intensive and intensive culture systems. Fish fed with formulated feed is used for their growth, maintenance, and reproduction. Feed Energy utilized for maintenance is mainly for health and survivability. In intensive aquaculture, animals almost exclusively depend on an external supply of high protein feed (generally >20%), usually based on fishmeal (Beveridge and Little, 2002) because of its high protein content, better bioavailability of amino acids, palatability, and unknown growth factors. Hence fish fed with a fish meal-based diet exhibits better growth performance, feed conversion, and fish health than fish fed with other animal and plant-based protein sources (Hardy and Tacon, 2002; Pike and Barlow, 2002; Tacon, 2003; Cook et al., 1996). Still, Global fish meal production is annually decreasing since 1994 due to increased human utilization and increased use of fish residues and by-products, increasingly replacing whole fish for fish meal (FAO, 2020). Hence many scientists were passionate about replacing the fish meal with an alternative feed ingredient without compromising growth.

Introduction
Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse.
UNEP defines Environmental Impact Assessment (EIA) as a tool used to identify the environmental, social and economic impacts of a project prior to decision-making. It aims to predict environmental impacts at an early stage in project planning and design, find ways and means to reduce adverse impacts, shape projects to suit the local environment and present the predictions and
options to decision-makers.
Environment Impact Assessment in India is statutorily backed by the Environment Protection Act, 1986 which contains various provisions on EIA methodology and process.
Evolution & History of EIA
EIA is termed as one of the best policy innovations in the 1900s. The main aim of EIA is to conserve the environment and bring out the best combination of economic and environmental costs and benefits. Read the below-mentioned points to understand the Environmental Impact Assessment evolution and history:
• The birth of EIA is dated back to the 1970s.

Introduction 
Over the past few decades, magnetic nanoparticles (MNPs) have been showing great importance in the field of organic synthetic reactions, catalysis, sensors, biomedicines, environment rehabilitation, etc. (Gawande, M. B. et al., 2013; Del Rio, M. et al., 2022). Numerous research teams have recognized the significance of solid support materials for the creation of environmentally acceptable nano catalysts with high catalytic activity in light of the infinite advantages of MNPs (Sharma, R. K. et al., 2016; Gawande, M. B. et al., 2013; Deng, J. et al., 2011; Nasrollahzadeh, M. et al., 2015; Hudson, R. et al., 2014; Payra, S. et al., 2017; Chng, L. L. et al., 2013; Parandhaman, T. et al., 2017; Zhang, F. et al., 2014; Pourjavadi, A. et al., 2012). Heterogeneous catalysts in organic chemistry are solid catalysts that, while remaining in a distinct phase (usually solid) from the reactants (generally liquids or gasses), promote chemical reactions without being consumed in the process. These catalysts, which have multiple benefits such as ease of separation, recyclability, and selective reactivity, are essential in a variety of industrial processes and laboratory reactions (Lattuada, M. et al., 2007; Jiang, K. et al., 2011). The standard formula for ferrite nanoparticles is MFe2O4, where M is usually divalent metal ion like copper (Cu), zinc (Zn), or nickel (Ni), and iron (Fe) is the common metal (Kazemi, M. et al., 2018). These nanoparticles work very well as heterogeneous catalysts in a variety of chemical reactions because of their special magnetic and electrical characteristics.Because of its special qualities as a catalyst in a variety of processes, copper ferrite (CuFeO4), a mixed-metal oxide, has drawn interest in organic chemistry (Kharisov, B. I. et al., 2019; Zhu, J. et al., 2014; Vannucci, A. K. et al., 2012). It is a spinel-type ferrite that can catalyse a variety of organic transformations because it combines iron and copper in a stable, highly active structure. With benefits including high stability, reusability, and low toxicity, these catalysts are frequently employed in processes like oxidation, coupling, and reduction (Taghavi Fardood, S. et al., 2018). The Figure 1 represents schematic diagram of a reaction where the ferrite nanoparticles as catalyst have been recovered with the aid of an external magnet after the formation of reaction product.

Bonsai first appeared in China over a thousand years ago on a very basic scale, known as pun-sai, where it was the practice of growing single specimen trees in pots. These early specimens displayed sparse foliage and rugged gnarled trunks which often looked like animals, dragons and birds.

With Japan’s adoption of many cultural trademarks of China, bonsai was also introduced to Japan during the Kamakura period (1185-1333) by means of Zen Buddhism, which at that time was rapidly spreading around Asia. Once bonsai was introduced into Japan, the art was refined to an extent not yet approached in China. Over time, bonsai, which was confined to the Buddhist monks and their monasteries, were introduced as a symbol of prestige and honour. It became an important part of Japanese life by being displayed on specially designed shelves.  For the Japanese, bonsai represents a fusion of strong ancient beliefs with the Eastern philosophies of the harmony between man, the soul and nature.

Pulse crops provide nutritious food, feed and fodder and thrive well in fragile eco-systems where other crops often fail. They have the ability to trap atmospheric nitrogen in their root nodules in association with Rhizobium, bringing qualitative improvement in soil health i.e. physical, chemical and biological properties of the soil.  These virtues enable pulse crops to remain an integral part of subsistence farming system of semi-arid tropics as well as of Indo-gangatic plains. The role of pulses has also been recognized for sustaining soil productivity under intensive cropping systems in irrigated conditions.

1. Introduction

Plant diversity is vital for the survival and well-being of humanity. A number of domesticated plant species are critical to food security. In addition to the cultivated species, many wild plants also play an important role in meeting local needs for food, fuel, medicine and construction materials; crop wild relatives are also of special interest for crop breeding programmes. There are currently hundreds of underutilized plant species and varieties displaying traits of interest to meet present and future needs, while the value of many other plant species is yet to be discovered (Stohlgren et al. 1997). Researchers have confirmed the importance of the contributions and interdisciplinary understanding in relation to taxonomy, physiology, reproductive biology, conservation biology, hydrology, soils, as well as socioeconomic and climate change for holistic understanding of biodiversity patterns (Dale 1999; Myers et al. 2000). It is thus necessary that the professionals studying plant diversity require a synoptic view on the regulators of biodiversity and the tools through which the processes could be understood.

Spatial analysis can contribute significantly for improved understanding and monitoring of plant diversity. Results obtained from spatial analysis make it possible to formulate and implement targeted conservation strategies, which can be more effective (Escudero et al. 2003; Dale 1999). Outputs from spatial studies can provide critical information like evaluation of the current status of plant species and prioritize areas for conservation on the plant diversity, in particular geographic region. Spatial information, combined with available characterization and/or evaluation data, is very useful for effective genebank management (e.g. definition of core collections, identification of collection gaps, etc.). This type of analysis is conducted using Geographic Information System (GIS) tools, which allows one to carry out complex analyses combining different (spatial) data sources and generate maps, to facilitate the development and implementation of conservation policies (Goodchild 1992; Crosetto et al. 2000; McCarthy 2001).

Crops plants are broadly classified into two groups based on their mode of reproduction viz. sexually propagated and asexually propagated. In sexually propagated crops seeds are the primary propagules and it is produced by the fertilization of male and female gametes. Whereas, asexual reproduction or clonal reproduction covers all those modes of multiplication of plants where normal gamete formation and fertilization does not take place and vegetative propagules are the means of reproduction. Since sexual reproduction involves meiosis, segregation and recombination, the creation of variation is a continuous process which is inevitable in these crops. On the other hand, in asexual propagation progenies are identical to the parent clones and they are genetically similar without any variation and they reproduce via mitosis. The most important vegetatively propagated food crops are potato, sugar cane, cassava, sweet potato, yam, plantain/banana, and fruit trees. Other crops with asexual propagations are some ornamentals, grasses, and forages.
