Pulses are high in protein, fibre, and various vitamins, provide amino acids, and are hearty crops. They are most popular in developing countries, but are increasingly becoming recognized as an excellent part of a healthy diet throughout the world. Pulse crops are one of the most sustainable crops a farmer can grow. It takes just 163 litres of water to produce 0.45 kg (1 pound) of pulses, compared with 818 litres for soybeans. They also contribute to soil fertility by fixing nitrogen in the soil.

Agriculture is the most important sector in India in terms of the population dependent on it. Although agriculture now accounts for on 14 per cent of GDP, it is still main source of livelihood for the majority of the rural population. Rapid growth of agriculture is critical for development of rural economy and viable development of rural economy will leads to overall development of country. Diversification in agriculture is need of the hour, any cropping system comprising crops with varied maturity period, crop canopy and high yielding potential is need for an average farmer. Again cropping systems depending upon the soil type, total rainfall and arrival of monsoon in the region. Low cost technology is essential for reducing financial burden on farmers and to increase production on sustainable manner.

Introduction

Over the years, antibiotics have been used at sub therapeutic levels for enhancing the production and immunity of birds. The advantages of using antibiotics as feed supplements in terms of improvement of growth and feed efficiency have been well documented. However, the growing concern over the transmission and the proliferation of resistant bacteria via the food chain led to a ban on the use of antibiotic growth promoters (AGP) in livestock within the European Union in 2006.Thus, quest for alternatives to AGP gained momentum in the first decade of this century. There has been emergence of various feed additives like prebiotics, probiotics, organic acids, enzymes, essential oils, fatty acids, phytobiotics etc. Feed additives are used in to elicit the production performance and health of chicken.

    1.    Cereals are grown over 73% of the total world harvested area and contribute over 60% of the world food production providing dietary fibre, proteins, energy, minerals,  vitamins, b-glucans , Oligosaccharides, such as lactulose, fructo-oligosaccharides, transgalacto-oligosaccharides

    2.    Finger millet is a potent source of antioxidants and has potent radical-scavenging activity that is higher than that of wheat, rice, and other millets; these results corresponded to their phenolic content

    3.    The brown or red variety of finger millet, which is commonly available, had higher activity (94%) than the white variety (4%) using the DPPH method.

    4.    Most of the herbal plant polyphenols are known to have multi functional properties such as reducing agents, hydrogen donating antioxidants and singlet oxygen quenchers and flavonoids and their derivatives are the largest and most important group of polyphenols.

    5.    Phytosterols are found in plant foods and are structurally and functionally analogous to cholesterol in vertebrate animals. a-sitosterol, campesterol and stigmasterol are the most commonly occurring phytosterols and constitute 95% of total phytosterols in the diet.

Introduction

It is considered to be one of the most ancient machine tools, having evolved from the early tree lathe, which was a new mechanism for turning and milling items held between two nearby trees at the time. The job rotated sporadically due to a rope wound around the work, with one end linked to a flexible limb of a tree and the other end being pulled by a worker. Then hand tools were employed.

The machine was given the name “lathe” when a strip of wood called “lath” was used to support the rope during its construction. This technology evolved over centuries, and in 1797, an Englishman named Henry Maudslay invented the first screw-cutting lathe, which is the ancestor of today’s high-speed, heavy-duty production lathe.

Grasspea (Lathyrus sativus L.), also called chickling pea, is an important crop of economic significance in India, Bangladesh, Pakistan, Nepal and Ethiopia. It is also cultivated in China, many countries of Europe, the Middle East and northern Africa. It is a food, feed and fodder crop belonging to the family Leguminacaae and the tribe vicieae (Smartt, 1990).

Grasspea is very tolerant to drought conditions and has been grown successfully in areas with an average annual precipitation of 380 to 650 mm. Despite its tolerance to drought, grasspea is not affected by excessive rainfall and can be grown on land subject to flooding (Sinha, 1977). It has a very hardy and penetrating root system and, therefore, can be grown on a wide range of soil type, including very poor soil and heavy clays. This hardiness together with its ability to fix atmospheric nitrogen makes the crop ideally to grow under adverse conditions (Campbell et al. 1994). In India, Bangladesh, Nepal and Pakistan, it is often broadcast into a standing rice crop one to two weeks before the rice is ready for harvest where it flourishes on the residual soil moisture after the rice has been harvested.

Despite all the advantages compared to other crops, relatively little efforts have been made to improve this very hardy pulse crop. The main reason has been the knowledge that excessive consumption of grasspea can lead to a neurological disorder, called Lathyrism in man and domestic animals (Jackson and Yunus, 1984). It appears when Lathyrys sativus forms the main component of the diet contributing to at least 30% of the caloric intake for a period of 3 to 4 months (Campbell et al. 1994).

In this chapter, we explore Latin square design (LSD), a specialized form of experimental design renowned for its efficiency in controlling variation. This chapter thoroughly discovers the foundational principles, structure, and application of LSD in experimental research. It details mathematical models for LSD and guides readers through the interpretation of ANOVA tables. Furthermore, the chapter provides a systematic approach to conducting LSD analysis using R software.

Latin Square Design

The LSD is a statistical design used extensively in experiments, especially when specific conditions are met:

• Controlled variation in two directions: LSD is particularly suited for experiments where variation can be controlled along two different factors. This design structures the experimental units into a square matrix, allowing two sources of variability to be accounted for.

• Adherence to experimental design principles: Like other designs, LSD follows the key principles of randomization, replication, and local control. Randomization in LSD is applied within the rows and columns of the square matrix, ensuring unbiased treatment comparisons.

• Efficient use of resources: LSD allows for an effective utilization of resources by controlling two variables simultaneously. This makes it a more efficient design compared to RBD or CRD when there are two sources of nuisance variables.

Introduction

As a chief feature of RCBD, formation of blocks is a necessity to achieve homogeneity of plots within each block so that an irrevelant source of variation existing to the error component could be removed for purposes of treatment comparisons. But quite frequently, in agricultural experiments, the fertility gradient varies in all directions so that the plots within a block in RCBD could still be heterogeneous. In order to control or remove this additional source of variation, one can think of extending the concept of blocking yet in another direction , orthogonal to the first direction, leading to a new design called Latin Square Design(LSD). In otherwords, if the blocking concept is one-dimensional in RCBD, it is two-dimensional in LSD. As a guiding principle for formation of two-dimensional blocks, it may be stated that each row-block and each column–block should remove as much variability as is possible from total variability so that error component becomes smaller. The chief restrictive features of LSD are:

11.1. Origin and distribution

• Indigenous to Mediterranean region, growing wild in higher hills of Southern France, Italy and Bulgaria.

11.2. Economic importance

• True lavender (Lavendula angustifolia Mill sub. sp augustifolia)

• Spike lavender (Lavendula latifolia Mill sub. sp spica)

• True lavender - used in perfumery industry.

• Lavandin - hybrid between true and spike lavender

• Lavender oil - delightfully clean, refreshing and sweet odour.

• Main constituent - ester, linalyl acetate 30 to 60%

• Another compound - ethyl-n-amyl ketone.

• Free linalool - major component

I. MANDATE OF COPYRIGHT LAW

The importance of intellectual property rights has arisen in recent years to a great extent. The law of copyrights protects original forms of expression i.e. Novels, Movies, Musical compositions and computer software etc. Earlier it was mainly confined to the -published Work and owner of it could prevent others from getting it published in the form of books or articles in order to get benefit in terms of money or goodwill or reputation. In case of such undue enrichment, the owner had a valid cause of action. The owner of the copyright has a valid cause of action against the violator. At present even in case of its adoption and translation or abridgement, it is obligatory to have consent of author. The main purpose and object of copyright law is to protect the expression in any other form from unauthorized use. Since 1847, the copyrights law is in developing stage so, many legislations has been enacted.1 With the changing of times, the meaning of expression also changes and the style of exhibit the things also changed. The right of author who gives expression in any form is protected from unauthorized use.

Lawn is an integral part of any garden and it gives pleasure while sitting during evening in summer and one can enjoy good sunshine during winter. Hence, it is often referred as “heart of the garden”. It is covered with perennial grass and provides open landscape to the house and adds aesthetic beauty to the surroundings. Good lawn is essential to have in a good garden. It is permanent feature, which occupies 60% share of total garden area. Here in this chapter lawn is divided into two parts. There are approximately 620 genera and 10,000 species of grasses worldwide. Grasses are used extensively used throughout the world for their beauty and utility. Grasses are found from temperate to tropical to arid semi arid regions and suits in most extreme climatic conditions and have adapted to a worldwide climate and zones. Grasses are used as fodder, food, medicinal and for aesthetics purpose and it belongs to family Gramineae.

Lawn

The lawn is a plot of closely mowed grasses. It is composed of thousands of individual plants crowded and forced into a very unnatural growth habit. It is an integral part of the garden. It is basically an area of land planted between gardens covered with grass and other low lying plants.

Lawn is one of the most important features of a garden. A well kept lawn makes a garden look extremely beautiful. It looks like a beautiful green carpet amidst colourful flowers in a garden. Lawn can be called as turf, pitch, field or green depending upon its plantation and usage. Selection of lawn grass depends upon it usage and its season of plantation. Though a well maintained lawn requires a little of patience and care, the final results are always very beautiful and soothing. Scientific reports say that lawns reduce energy consumption through it soothing effects and the green grass prevents soil erosion as well as cut down noise pollution in the urban areas.

Lawn is the basic feature of garden without which a garden is seldom complete. All other features are selected and placed considering lawn as a first primary feature. A well spread out land planted with uniform lush green grass of particular type serves as a heart of all gardens. Lawn with systematic planting of shrubs and seasonal flower beds along with well placed specimen plants is the most striking feature of the garden.

Developing a good lawn is not an easy task. One has to consider many things like selection of site, preparation of the land and type of grass to be planted besides its maintenance. Following points need to be considered while developing a lawn.

Site and Soil

Selection of site is an important primary factor. Under full or partial shade, a good lawn can not be developed. The part of proposed garden which receives full sunlight at least four hours a day preferably in the morning should be selected as a site for lawn. Planting of tall trees is to be avoided at the south and south-eastern side of the lawn which obstructs sunlight and provides shade.

Lawn

Lawn is a natural green carpet, and it is important feature of a landscape and a garden without a lawn is not considered complete. Lawn is an area of land closed mowed grasses it is primarily developed for aesthetic and recreational purpose. A lawn is an integral part of a garden and landscape besides aesthetic and recreational purpose and several other purposes. Lawn provides a place for taking rest after tiring of the day, holding parties, social functions, passive and active recreation. Distinguishing characteristic of turf grasses is the ability to with stand close mowing and still providing a functional dense healthy ground cover. Lawn is also called as heart of garden. J.B. Olcoth designed first experiment in lawn grass at Monchester in USA in the 19th century. Festuca and Agrostis species were used to make turf (Lawn) during 1880 in U.K. In the early 19th century lawn become wild spread out side of parks golf course. Now a day in many metro cities of India lawn has become a cultural of the passion of many homes.

Definition: A lawn is an area of land of closely mowed grasses that is primarily developed for aesthetic and recreational purpose.

A lawn is an integral part of a garden or landscape. Besides aesthetic and recreational purposes, lawn serves several other purposes. The distinguishing characteristic of turf grasses is the ability to withstand close mowing and still providing a functional, dense and healthy ground cover. Its maintenance requires little patience and care, however the final result is always worth waiting as it gives very beautiful and soothing effect to the landscape. It is also called as ‘Heart of garden’.

Lawn can be called as turf, pitch, field, sod, yard or green depending upon the plantation, usage and continent.

Meat and meat products industry is a sunrise industry in India having huge potential for upliftment of agricultural economy. India is the second largest food producer in world but the contribution of meat industry is still confined to localized handlers. So to uplift industry basic infrastructure, food chains, food security and safety along with standards and laws formulation and their implementations is today’s need. Standards are carefully drawn specifications with respect to a food product. These standards are mainly of three types i.e. government, trade and research standards. Government standards are formulated by the government of India or state government and also have the power to implement these standards while trade standards are implied by the individual company. Research standards are formulated on the basis of comparative study of the products by the researchers. Laws are the legislations enforced by the organisations either government or by autonomous bodies made under the constitutional acts of the country. At present numerous standards and laws are in existence in individual country or at international level. The need is to harmonize them as per the industry and trade requirement.

Domestic Organizations Involved in Standards and Laws Formulation

For the formulation, enforcement and control of standards and legislations at domestic level various organizations are of prime value. Some of these are:

In production one or a combination of the following relationship are commonly observed:

1. The law of constant marginal returns (productivity)

 2. The law of increasing marginal returns (productivity)

 3. The law of decreasing marginal returns (productivity)

17.1 Introduction

The plant layout needs a proper arrangement of each constituent area, along with their interrelationship. One of the most important considerations is the future expansion potential. The plant layout design should permit expansion readily and economically. One side of the building should be free of permanent installations such as compressors, septic tanks, toilets, drain fields, offices, and loading docks to permit the addition of building units without relocating these auxiliary facilities.

Animal protein has a great importance in human health by providing essential amino acids. It is supplied by the milk, meat, fish, eggs etc. Specifically meat has a prime position in the human’s diet particularly for those who are non- vegetarians. As per Indian Council of Medical Research (ICMR) recommendations a normal human being requires 60 gram protein in a day with the net protein utilization (NPU) of 65. In ideal cases 30 to 50 percent of daily protein intake should be from animal sources to get optimal range of amino acids. In present scenario human beings all over the globe are getting 29 gram of protein while developing countries have 15 g per day availability and developed nations are getting 60 grams protein per day per head. However, in India availability of protein is only 10 grams/day/head.

The plan reviewing the arrangement of fruit plants in an orchard is known as the orchard layout. Although several systems of planting are followed to increase the production of orchard, selection of root stocks, soil, system of training pruning and cultivars are very important factor influencing designing of layout. However, improper system results in overlapping of plant parts, competition for water, light, nutrient and unequal distribution of water etc., which ultimately results in poor performance or fruit orchard.

Layout plan

The marking of position of the plant in the field is referred as layout. The layout plan of the orchard should be prepared carefully, preferably in consultation with horticultural experts or fruit scientists. The orchard layout plan includes the system of planning provision for orchard paths, roads, water channels and farm building. A sketch of the proposed orchard should be prepared before the actual planting is taken up.

Objectives

1. To know the layout methods.
2. To know the planting techniques of various spices and condiments.

Layout: Systematic arrangements of plants

Some spices and condiments just like clove, cardamom is perennial in nature. Being perennial in nature any mistake committed during initial year, on the part of planning, is hard to rectify. Hence, all the factors having bearing on growth, production and overall performance of the plant should be given top priority.

Systems of planting

1. Square system: In this system row to row distance and plant to plant distance is kept similar.

Formation of a Rectangle

Experiments are usually laid out in square or rectangular plots for data and yield estimation, even though the field may be irregular. The plot is usually placed on the contour, parallel with a road, or in a north-and-south alignment. To mark a plot, construct a right angle and then form a rectangle or square.

What is Nursery?

Nursery is a place, where seedlings, samplings, trees and other plant material are grown and maintained until they are planted in permanent place. Setting up of a horticultural nursery is a long term venture and needs proper planning for good return.

Establishment of Nursery

To be a viable venture, the nursery should be established in such an area where cultivation of fruit crops is on sizeable area and there is need for a nursery, having demand for saplings. In such area/region, following considerations need to be observed for selecting an appropriate location.

The tissue/cell culture lab has the requirement of maintaining an aseptic environment. There are several aspects to the design of good tissue culture facilities. Ideally, cell culture work should be conducted in a single-use facility. Therefore, cell culture lab unit should be separated from the rest of the lab area. It can be either separate lab or a closed partition in a big lab. All new material should be handled as ‘quarantine’ material in a separate area, and materials known to be free of contaminants should only be allowed inside the culture room. In addition, the work surfaces should be thoroughly cleaned and disinfected between activities.

For most of the work involving non-infectious primary culture and cell lines, the laboratory should be designated to at least BSL2 facility. The location of the Biosafety cabinet is the most important point to consider. When operated correctly, the cabinet will provide a clean working environment, whilst protecting the operator from aerosols. Environmental monitoring with Tryptone Soy Broth agar settle plates inside the biosafety cabinet is a good indicator of the cleanliness of a cabinet. There should be no growth of bacteria and fungi after 3-5 days of incubation.

4.1. Area approach

National Credit Council was set up in December, 1967

Study group in October, 1968 under chairmanship of Prof. D R Gadgil found that Commercial Banks had penetrated only 5000 villages as of June, 1967 and its share was 1% compared to co-operatives.

Recommended the adoption of an area approach for bridging the spatial and structural credit gaps.

All India Rural Credit Review Committee 1969 also endorsed the view the Commercial Banks should increasingly came forward to finance activities in rural areas.

RBI accepted recommendation and formulated Lead Bank Scheme (LBS) in December, 1969

Each district had been assigned to different banks (Public and private) to act as a consortium leader to coordinate branch expansion and credit planning.

Nationalization of 14 major Commercial Banks in July 1969 (Another 6 banks in 1980), paved the way for branch expansion network in unbanked rural and semi urban areas.

Introduction

In recent years, women have made remarkable strides in the veterinary field, bringing a wealth of skill and dedication to various sectors, including clinical practice, research, academia, and industry. Today, women comprise a significant portion of the veterinary workforce. However, the path to leadership and career advancement still presents unique challenges. Gender biases, limited representation in senior roles, and the constant balancing act between personal and professional life often stand in the way. As a woman in this field, I understand the significance of leadership development and the impact it has on creating a meaningful, rewarding career. This session aims to equip women veterinarians with actionable strategies and essential leadership skills to advance their careers meaningfully. Leadership is not merely a title; it’s about creating positive change, setting examples, and inspiring those around us. For women in veterinary medicine, it means breaking barriers, making a difference, and contributing to animal welfare and public health. By cultivating confidence and a focused approach, women can rise to leadership roles that truly make an impact.

Abstract

Leadership behavior is seen in every group of social animals like elephant, honey bee, human being, etc. Initially people thought this behavior as inborn character and only few lucky people possessed it. But now it has been proved that this character can be developed by interested people through systematic training. In every family parent are playing the role of either leader or manager and being a role model gradually transmitting this behavior to their children from childhood itself. Training begins at home of every successful leader.  In this article the characteristic features of leaders, style of their functioning, leadership theories and the difference between a leader and a manager are discussed in details. Important tips have been mentioned to follow for becoming a good and successful leader.

Leaf analysis and its importance

Improved fertilizer management for crops is important in view of today’s need to reduce production costs, conserve natural resources, and minimize possible negative environmental impacts. These goals can be achieved through optimum management of the fertilizer applied. Understanding the crop nutrient requirements and using soil testing to predict fertilizer needs are keys to fertilizer management efficiency.

Plant tissue testing is another tool for use in achieving a high degree of precision in fertilizer management. Timely tissue testing can help diagnose suspected nutrient problems or can simply assist in learning more about fertilizer management efficiency. Leaf analysis (also called stem leaf analysis, tissue analysis or foliar analysis) is the most precise method of monitoring plant nutrient levels. While soil analysis reveals the levels of essential soil nutrients, leaf analysis shows the grower exactly what the plant has successfully absorbed. Leaf analysis is especially helpful in detecting nutrient deficiencies before they affect plant health and yield.

1. INTRODUCTION

Leaf and soil analysis are the tools to estimate the fertilizer needs of fruit crops. Leaves are selected for analysis because:

• Leaf is the principal site of plant metabolism.
• The changes in nutrient supply are reflected in the leaf composition.
• The changes are more pronounced at certain stages of development.
• The concentration of nutrients in the leaf at specific growth stages are related to performance of the plant.

Mizoram in North East India, is located between 21º58’ to 23º35’ N latitude and 92º15’ to 93º29’ E longitude, surrounded by Tripura, Assam and Manipur in North frontier regions; Bangladesh in west; and Mayanmar in east and south. The undulated topography of Mizoram, known as Lushai hills during British period, has varied altitudes ranging from 21 to 2157 m above mean sea level, annual rainfall of 2000-3200 mm, and mean monthly temperature of summer (monsoon) ranges from 14.6ºC to 29.6ºC. Besides having good rainfall; the vegetable production, including leaf vegetables, during winter period is limited by acute soil moisture stress caused by high rate of evapo-transpiration, almost no rain from November-March, non-availability of irrigation water and low water holding capacity of the sloppy land (Singh et al., 2011; Singh et al., 2013b).

Leaf vegetables are rich sources of provitamin-A, vitamin-C and minerals like calcium, iron etc.  They also provide roughage required in human diet.  The Indian Council of Medical Research (1984) recommended a daily intake of 100 g and 40 g of leaf vegetables in the diet of woman and man, respectively. Amaranth, beet leaf, spinach, fenugreek, cabbage etc. are the major leaf vegetables grown in the country. In addition, a number of under-utilized annual crops are also grown as leaf vegetables in specific regions. Tender stems and leaves of a number of perennial crops are rich sources of vitamins and minerals and are used for cooking.  The major annual leaf vegetables have a few features in common:

ABSTRACT

The Indian short-nosed fruit bat, Cynopterus sphinx is one among the three paleotropical species known to make tents. Once a tent is made, male typically defends it against other competing males and also defends the females who join his tent.

Introduction

Leafy vegetables belong to an important group of vegetables and are highly nutritious due to their richness in Vitamin A (Carotene), Vitamin C, Folic acid, Riboflavin, Thiamine and minerals like Iron, Calcium and Phosphorus etc. Appreciable quantity of proteins is also found in these crops. They also provide a variety of phyto-nutrients including beta-carotene, lutein and zeaxanthin, which protect cells from damage, age-related problems, among many other effects. Dark green leaves even contain small amounts of Omega-3 fat. They are available at cheaper rate in the market as compared to other vegetables. They provide roughage and have an important place in the balanced diet. It is recommended that a daily intake of 100 g and 40 g of leafy vegetables in the diet of woman and man respectively. India is the 2^nd largest producer of leafy vegetables in the world after China, accounted for about 10% of the world production (Singh et al., 2006) but, the production levels of these leafy vegetables are very low because of lack of availability of high yielding varieties. Leafy vegetables are those crops from which leaves and associated parts are harvested for use as vegetable. The leaves of about 700 different kinds of plants belonging to125 families are consumed in the form of vegetables. The major leafy vegetables grown in the country are amaranth, spinach beet (desi palak), spinach and fenugreek. In addition to this a number of under-utilized annual crops are also grown as leafy vegetables in specific regions. Leafy vegetables are usually grown in kitchen and market gardens. Tender stems and leaves of a number of perennial crops are rich sources of vitamins and minerals and are used for cooking. Though leafy vegetables have high nitrate and oxalate levels, but adverse nutritional effects are not to be feared with a consumption level of 100-200 g per day. The commonly grown major leafy vegetables and their wild relatives are listed below

Introduction Palak (Beta vulgaris L. var. bengalensis), also known as spinach beet or perpetual spinach, Saag, Indian Spinach, beet leaf, Swiss chard and Palongpalang. is a leafy green vegetable that is closely related to Swiss chard (Beta vulgaris subsp. vulgaris). And it belongs to the family Chenopodiaceae. It is a popular and versatile vegetable known for its nutritious leaves and mild flavour. Palak shares similarities with both spinach (Spinacia oleracea) and beetroot (Beta vulgaris). The leaves of palak are tender and similar in appearance to spinach leaves. They are dark green and have a slightly glossy texture. The flavour of palak is milder compared to spinach, with a pleasant earthy taste. This makes it a versatile ingredient that can be used in various culinary preparations. Palak is often grown as a cool-season vegetable, as it can tolerate cool temperatures better than spinach. It is appreciated for its ability to produce a continuous harvest of leaves over an extended period, hence the name “perpetual spinach.” This characteristic makes it a valuable addition to home gardens and commercial production.

Improved Varieties of Leafy Vegetables

A. AMARANTHUS

Leaf vegetables are rich sources of provitamin-A, vitamin-C and minerals like calcium, iron etc. They also provide roughage required in human diet. The Indian Council of Medical Research (1984) recommended a daily intake of 100 g and 40 g of leaf vegetables in the diet of woman and man, respectively. Amaranth, beet leaf, spinach, fenugreek, cabbage etc. are the major leaf vegetables grown in the country. In addition, a number of under-utilized annual crops are also grown as leaf vegetables in specific regions. Tender stems and leaves of a number of perennial crops are rich sources of vitamins and minerals and are used for cooking. The major annual leaf vegetables have a few features in common:

1. Most of leaf vegetables are of short duration and the entire harvest is over within 80-90 days
2. Leaf vegetables are cultivated by direct sowing and by transplanting. In direct sowing, seeds are sown as in nursery and harvested 30 days after. In transplanted method, 25-30 days old seedlings are transplanted at a closer spacing and harvesting is done by frequent clippings or cuttings.

Leafy vegetables are rich source of vitamins like A, C and minerals like calcium and iron. Most of the leafy vegetables are quick growing types and shows good response to manures and fertilizers. Their easiness in cultivation and adaptation to diverse agroclimatic conditions makes it suitable for various cropping systems. Some of them are annual in nature while some others are perennial. Leaves as well as tender stems are uses as vegetable in the cooked form. They are reported to have antinutritional factors, oxalates and nitrates compared to other vegetables. The annual leafy vegetables are widely cultivating in our country and among them, amaranth, palak, spinach and fenugreek are the major ones. These crops are short duration in nature, completes their entire life cycle by 80-90 days and produce good yield and brings monetary returns to farmers in short time.

Amaranth (Amaranth sp.)

It is herbaceous fast growing annual leafy vegetable grown for leaves as well as grains. Vegetable amaranth is reported to be equal or superior in taste to that of spinach. Leaves and succulent stem are good source of vitamin A, vitamin C, calcium and iron and are used as vegetable. High oxalate and nitrate content are reported in some species of amaranth.

The major vegetable species of amaranth cultivating in India is A. ticolor. It is suggested to be originated in South or South east Asia particularly in India. Another vegetable type, A. dubius shows diversity in Central America, Indonesia, Asia and Africa. A. lividus is the popular vegetable type in South and Central Europe. Other leafy species are A. viridis, A. tristis and A. spinosus. A. cruentus, A. hypochondriacus and A. caudatus are cultivating for grain purpose. Taxonomists suggested two sections in Amaranthus namely blitopsis which include leafy types and amaranthus which constitutes grain types.

As we have seen how artificial Intelligence can be useful in agriculture but the nest question always come in mind is that from where and how we can start to learn and what are the model of learning an artificial Intelligence. As Artificial Intelligence is a huge part of Computer Science which means we need an language as medium to perform it and we always prefer Python for that which is very dynamic and easy to learn. In this chapter we will learn about python basics so that in further implementation of artificial Intelligence it will be helpful to us.

I. Introduction

Python is a remarkable language that can claim to be easy and strong. You will be amazed to see how simple it is not to focus on the language you are programming, but on solving the problem. Guido van Rossum was the creator of the Python language which is named after the BBC show “Monty Python’s flying Circus”.

Python is formally introduced as:

“Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.”

For economical ration -preparation, selection of cheap feed amongthe locally available sources, is an important point to ponder. For this purpose, a list of available feeds is prepared alongwith their latest costs on dry matter basis. The cost per kgof dry matter is divided by the amount of the nutrient (as a decimal), it will give us a good idea of the :

• Cost of Crude Protein in ??Protein supplements and,

• Cost of Energy in ??Energy feeds.

For example, if alpha alpha hay costs Rs 3.93 per kgof dry matter, the cost per kg of Crude Protein = 3.93/0.171 = Rs 22.98 per kg.

In this way, it is possible to prepare a list of protein sources in the order of “Ranking” from which feeds can be selected at lower costs.

Effect of Differences in Dry Matter

Feeds are purchased on the basis of Dry Matter due to variation of moisture content. For example :

A Corn of 89 % Dry Matter costs Rs 7 per kg,

Another type of corn of 75 % Dry Matter can’t be comparable on this cost This can be done as following 

What is Least Square Method?

The Least Squares Method is used to derive a generalized linear equation between two variables, one of which is independent and the other dependent on the former. The value of the independent variable is represented as the x-coordinate and that of the dependent variable is represented as the y-coordinate in a two-dimensional cartesian coordinate system. Initially, known values are marked on a plot. The plot obtained at this point is called a scatter plot. Then, we try to represent all the marked points as a straight line or a linear equation. The equation of such a line is obtained with the help of the least squares method. This is done to get the value of the dependent variable for an independent variable for which the value was initially unknown. This helps us to fill in the missing points in a data table or forecast the data. The method is discussed in detail as follows. The least-squares method was officially discovered and published by Adrien-Marie Legendre (1805), though it is usually also co-credited to Carl Friedrich Gauss (1809), who contributed significant theoretical advances to the method.

Least Square Method Definition

The least-squares method can be defined as a statistical method that is used to find the equation of the line of best fit related to the given data. This method is called so as it aims at reducing the sum of squares of deviations (residual part) as much as possible. The line obtained from such a method is called a regression line.

10.1 Introduction

Least square theory is a statistical technique used to estimate the parameters involved in the regression model in such a way that the sum of squares of errors (residuals) is minimum (least). We have generally two methods of estimation of population parameters. These are (i) Ordinary least square (O.L.S.) method and (ii) Maximum likelihood (M.L.) method. The method of ordinary least square (O.L.S.) is used extensively in regression analysis primarily because it is intutively appealing and mathematically much simpler than the method of maximum likelihood estimation (M.L.E.). In the context of lineaer regression analysis, the two methods generally give similar results.

Goats are used primarily for milk and meat production, but their skin is also a valuable by- product. Goats are an important source of hides and skin . The term hide is used to denote the outer covering of large animals such as cows, buffaloes, horses ,sheep, camel etc. The term “Skin” is applied to that of smaller animals such as sheep, goats , calves etc. Raw hides and skins are used mainly for the manufacture of leather.Goat skin is in great demand for making leather gloves , shoes , luggage, book covers etc.Goat skin was also used in many of the musical instruments .Goat skin has been used since time immemorial as water-containers. The water containers from goat skin were called “Mushk” and the person carrying such containers as “Bhisti”.Pelt is undressed skin of sheep & goats. To prevent putrefication, the skin is treated as well as preserved by dry salting and are graded according to curled type quality of the skin.

The Leather Industry holds a prominent place in the Indian economy. India produces 13.14% of the goat skin production of the world.This sector is known for its consistency in high export earnings and it is among the top ten foreign exchange earners for the country. With an annual turnover of over US$ 7 billion, the export of leather and leather products increased manifold over the past decades and touched US$ 3.40 billion in 2009-10; recording a cumulative annual growth rate of about 5.43% (5 years).It is estimaed that 72.3 million goat skins were produced in India in 2008 (FAOSTAT). India ranks second among the goat skin producing countries of the world, second only to China. India produced 130 thousand tones of goat skin in 2008 ( FAOSTAT) against China producing 351.7 thousand tones and Pakistan 94 thousand tonnes (FAO Stat).

The major production centers for leather and leather products are located in Tamil Nadu - Chennai, Ambur, Ranipet, Vaniyambadi, Trichy, Dindigul ; West Bengal –Kolkata ; Uttar Pradesh –Kanpur, Agra & Noida ; Maharashtra –Mumbai; Punjab –Jallandhar ; Karnataka –Bangalore ; Andhra Pradesh - Hyderabad ; Haryana - Ambala, Gurgaon, Panchkula and Karnal; Delhi. India is the second largest producer of leather footwear and garments in the world.

Leavening agents produce carbon dioxide which helps to give characteristic structure to bread cakes and biscuits etc. In the case of cakes, leavening is produced by air entrapped in the dough due to the presence of egg in the mix. The important groups of leavening agent’s are l. baker’s yeast 2. Chemical leavening agents

16.1 INTRODUCTION

The world floriculture business has reached to almost over a $ 40 billion mark. It is continuously going through the rapid transitional changes to have more unique and competitive products of wide choice to the consumers. Netherland is ahead in floriculture trade. Throughout the year, a large number of ornamental commodities are imported in Holland and exported back to the countries for its retail and consumption mostly to the countries in the Gulf, Middle-East Asia and America. According to the statistical estimates worldwide, a large quantity is consumed in US and the other countries. For an example, the US alone consumes 100 lacs of cut flowers a day and approximately 4000 lacs every year, though it ranks only 17^th in per capita cut-flower consumption. The average Swiss spends Rs 4500 a year on flowers, nearly four times than that spent by the average American besides the fact that the consumption of fresh cut flower and foliage plant is on manifold increase every year resulting in the competition worldwide for growing of exportable eco-friendly products. At the same time there is great environmental consciousness towards transforming floriculture with “natural and unspoiled” system of having the exportable produce into a mass and its ease to transport to any distant market. The system relies greatly on the industry with extensive network of breeders, greenhouse managers, field workers, auction houses, sales representatives, shippers, and florists to offer consumers a variety of choices matching their taste. This is the fact that in the recent times, the commercial growers don’t rely on the nature to introduce the genetic mutation that will make them millionaires but depends on the art and scientific knowhow to create a novelty in its own. This has resulted in the seriousness and painstaking effort of the growers to produce the plants in new forms and shape to put forward a new plant with extra-ordinary marketable characteristics every year, e.g. compact chrysanthemum, kalanchoe, bromeliads, orchids, etc (Plate1) are some of the common products with an unusual and eye-catching hue in the European markets. Similarly, the consumers can purchase gerberas with blooms as wide as salad plates and roses with yard-long stems perfectly suited for valentine-day gifts which mainly they get produced under the specific and artificial environment created for a specific growth stages of the plant.

The landscape gardening for aesthetic appreciation is an integral part of the progress achieved through the growing world floriculture business that has reached a $ 40 billion mark and valueless aesthetic emotional gains. The industry is continuously rising through transitional changes to have more accepted and unique applications as a wide and economic choice to the consumers with regards to the energy saving in the system. The use of energy for sustenance of the landscape plants before and after planting can be a benchmark in time to come as no one can believe that the plants instead can grow with still better traits either be it the foliage colour, variegation, shape, size and or form beside the fact that the consumption of such altered/compact plants has increased manifold in house, gardens, parks and indoors with a large number of products worldwide in a eco-friendly manner.

At the same time there is great environmental consciousness towards transforming landscape gardening with more natural and unspoiled system of growing plants and maintaining them in the landscape as perennial ones. The system being independent of distance of use or application offers an ease of transport into a mass for large-scale uniform planting. This is the fact that in the recent times, the commercial growers do not rely on the nature to introduce the genetic mutation that will make them millionaires but depends on the art and scientific knowhow to create a novelty in its own. This has resulted in the seriousness and painstaking effort of the growers to produce the plants round the year in new forms and shapes to put forward a new plant with extra-ordinary marketable characteristics every year, e.g. compact chrysanthemum, kalanchoe, bromeliads, orchids, etc are some of the common products with an unusual and eye-catching hue in the auction markets. Similarly, a large number of annual and perennial plants perfectly suited for various kind of landscaping, slope, soil types and moisture regimes under the specific and artificial environment created for a specific growth of the plant.

The leek is a centuries-old crop native to the eastern Mediterranean and the Middle East. The plant is linked to the onion, and its flavour is mild, sweet, and onion-like. Leek stalks are commonly used in European soups and stews, particularly as a side dish with potatoes, and can be cooked whole as a vegetable. It is a non-bulb producing onion family member farmed for blanched stem and leaves. It is eaten fresh or combined into salads, and it is cooked as a flavouring in soups and stews. It is not grown commercially in India, although it is a popular vegetable in a kitchen garden. The climate and soil conditions are the same as for onion.

Botany and taxonomy: The leek is a vegetable that is a cultivar of Allium ampeloprasum, often known as the broadleaf wild leek. 

I. ROLE OF INTELLECTUAL PROPERTY

The international community has set itself the target of reducing the proportion of people below poverty line to half by 2015, along with associated specific targets for improving health and education and environmental sustainability. The Millennium Development Goals, adopted at various international fora, recognize the crucial importance of reducing poverty and hunger, improving health and education, and ensuring environmental sustainability. It is important to know whether and how intellectual property rights (IPRs) could play a role in helping the world meet these targets — in particular by reducing poverty, helping to combat diseases, enhancing access to education and contributing to sustainable development, protecting our cultural heritage, safeguarding the food security for the country. It is also necessary to deliberate whether and how they create obstacles to meeting those targets and, if so, how those obstacles can be removed.

There are strong views from both sides on the protection and enforcement of IPRs though there is no data to check these views objectively. Some argue strongly that IPRs are necessary to stimulate economic growth, which in turn, helps in poverty reduction. By stimulating invention and new technologies, IPRs help to increase agricultural or industrial production, promote domestic and foreign investment, facilitate technology transfer and improve the availability of medicines necessary to combat diseases. They are also of the view that there is no reason why a system that has worked for developed countries would not work for developing countries. Others argue equally vehemently the opposite. IPRs do little to stimulate invention in developing countries, because the necessary human and technical capacity may be absent there. In assessing these opposing arguments, it is important to remember the technological disparity between developed and developing countries as a group. What role the intellectual property can play to plug this gap is a serious subject for every developing nation? For this, it is also pertinent to know about the IPRs, the challenges they pose to the legal system in general and to the Indian legal system in particular, and their basic rationale to take a considered approach in their implementation.

Introduction

Agribusiness refers to the industry that deals with farming and the selling of agricultural products, including the cultivation of crops, their processing, and their distribution to retailers. Producing and distributing crops, agrichemicals, fodder, breeding, farm equipment, seed supply, raw and processed commodities of food and fibre, warehousing, transporting, packing, marketing, retailing, soil testing, and testing for nutrient deficiencies are all part of the agribusiness industry.

It's important for an excellent brand name to provide a solid basis on which a company can grow. Companies need to identify who they are trying to sell to. Will people have no trouble pronouncing it? The tongue shouldn't have to work too hard to say it. Can you pronounce the name easily? Your brand name needs to be audible to consumers. Have you tested the name's spelling ability?

Choosing what aspect of agriculture or agribusiness you want to enter is the f irst step. So, you can't make a call like this until you have a firm grasp on your company's long-term goals, operational strategy, and financial situation. You can still enter the market if you aren't an expert in the equipment, products, grains, soil, seeds, or plants involved; nevertheless, you should go in with your eyes wide open, a well-thought-out business plan, and a competent team.
