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

Scientific name: Lavandula angustifolia Mill.
Family: Lamiaceae
Lavender is a small genus of perennial aromatic herbs, semi-shrubs, or shrubs. It comprises approximately 28 species, with three species being extensively utilized for extracting essential oils:
True Lavender (Lavandula angustifolia): One of the most important essential oils used in the perfumery industry.
Spike Lavender (Lavandula latifolia): Yields inferior oil, less fragrant than true lavender and rosemary.
Lavandin (Lavandula hybrida): is a hybrid of true lavender and spike lavender, possessing characteristics of both parents. The essential oil extracted from Lavandin combines the sweet, floral fragrance of true lavender with the camphoraceous harshness of spike lavender. Although Lavandin oil has a unique fragrance profile, it is considered inferior to true lavender oil in terms of quality and finesse.
Origin and distribution
Lavender originates from the Mediterranean basin, typically thriving in rocky, calcareous areas. Its distribution spans North Africa, the Mediterranean, Europe, and Western India. Lavender has been cultivated since ancient times, with the Greeks and Romans being notable cultivators. The name "lavender" is derived from the Latin verb "lavare," meaning "to wash" or "to bathe."

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.

10.1. Introduction
In the production process, the farmers combine the required input factor in various proportion. This type of usage of input by the farmer gives way for the operation of law of returns. In the production process, when the single input factor is varied keeping other required factor constant, the relationship take place between single variable input and the consequent output pertain to either one or a combination of the following relationship.
1. Law of increasing returns;
2. Law of constant returns; and
3. Law of decreasing returns.
10.1.1. Law of increasing returns
According to the law of increasing returns, each additional (or marginal) unit of input leads to a proportionally larger increase in output compared to the previous unit. In other words, the productivity of inputs rises as more units are employed.

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

Lawn is a natural green carpet, and it is important feature of a landscape and a garden without a lawn is not considerd 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. Lawn can be called as turf pitch a field, sod, yard, are green depending upon the plantation usage continent. Lawn is a ground cover of perennial grass, ditch, persists enclose mowing and require proper management practice.

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.

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.

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.

Advertising plays a crucial role in modern business, influencing consumer behavior and shaping market trends. However, the power of advertising necessitates a framework of laws and ethical guidelines to ensure that messages remain truthful, fair, and socially responsible. This chapter explores the legal and ethical considerations in advertising, highlighting key regulations, ethical principles, and real-world implications.

Public Relations (PR) professionals operate at the intersection of communication, media, business, and society. Their work shapes public perception, builds relationships, and influences the decision-making of individuals and groups. To ensure that this influence is wielded responsibly, PR professionals are guided by both legal frameworks and ethical standards. In this chapter, we will discuss the laws that govern PR practices, the ethical principles that guide professionals in the field, and relevant case studies that illustrate the importance of adhering to these laws and ethical standards.
Introduction to PR Laws and Ethics
The role of public relations has evolved to demand accountability, transparency, and ethical responsibility. The impact that PR practitioners have on society makes it essential for them to follow legal requirements while maintaining high ethical standards. Laws governing PR are often derived from broader communications and media regulations, while ethics are typically guided by professional codes of conduct. Laws represent minimum standards enforced by legal authorities, while ethics go beyond the legal realm, embodying the moral responsibilities of PR professionals.
