4.1 Introduction
Companies that produce tangible items or offer services must drastically increase their productivity in order to maintain their operations in the face of intensifying global competition. A single quantum jump productivity enhancement technique or multiple concurrent incremental improvement productivity strategies can both be used to achieve this goal. If a business chooses the second choice, integrating various tactics for a significant increase in the total productivity would be quite difficult. The first alternative, a single productivity improvement plan, will make it possible for the business to increase productivity with the same or greater success. The only difficulty with this strategy is locating the probable problem area and then using process improvement techniques to achieve the anticipated dramatic increase in productivity. Business process reengineering refers to any significant adjustment of business processes that results in a dramatic increase in an organization’s productivity. Price, quality, after-sales support, adherence to delivery schedules, technological breakthroughs, etc. are some elements that influence market competition. Therefore, the business should focus its efforts on each of these areas in order to achieve notable improvements in terms of decreased operating costs and higher sales revenue from the sale of its goods and services to clients. Improved pricing for a company’s goods or services can provide it an advantage over competitions. Applying various cost-cutting strategies to lower variable costs and overhead costs will lower the price of the good or service. The other elements, viz. quality, after-sales support, delivery schedule adherence, and technological advancements are all directed in this direction

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.

Exotic vegetables are those vegetables that are introduced or not common in India. Its area under cultivation is comparatively less and most of the growing area surrounds the targeted markets especially five star hotels and restaurants. Now a days, there is an increasing trend in cultivation of these high value vegetables because of increased demand and good profit. Farmers could sell these vegetables at a at a higher price when compared to traditional vegetables. They are mostly cultivated in net houses or poly houses. Some of the exotic vegetables popular in India are asparagus, celery, broccoli, lettuce, parsley etc.

Asparagus (Asparagus officinalis)

Asparagus is a dioecious monocot which produces tender succulent above ground stems known as spears from fleshy underground crown. These tender spears are used as vegetable, for cooking purpose and for the preparation of soups. The white crystalline substance, asparagine present in the juice of young shoots have diuretic properties and is used in cardiac dropsy and chronic gut. Asparagus is mainly cultivating in countries like USA, Germany, Spain, France etc. while in India, it is cultivating only in a negligible area. Asparagus is grouped under cool season vegetables. But newly emerging spears are susceptible to frost though a wide range of environmental conditions can be tolerated by mature asparagus. Asparagus is native to temperate Europe and Asia and has been cultivating for 200 years.

Morphology

Asparagus is perennial in nature and produce erect branched stem and grows upto a height of 1 to 3 m. The crop yield continuously for 10-15 years from the initial year of spear production. Asparagus roots are tuberous and the leaves are narrow and needle like. Male and female flowers are produced in different plants.

Abstract

The forest cover has declined at an estimated rate of 3-3.5% per annum due to huge deforestation in many countries during last decades. Being the prime necessity for forest regeneration, importance of quality seed management and its handling procedures have been genuinely recognized for greater interest of the environmental stability throughout the world. Growing of new trees and forests would play a major role to save the future world particularly under the present scenario of climatic change and this implies an increased demand of quality forest reproductive materials.

Seed

A true seed is defined as a fertilized mature ovule consisting of embryo, stored material and protective coats. The seed strictly speaking is an embryo a living organism embedded in the supporting or the food storage tissue.

A seed stands for any of the following used for sowing or planting.

1.    Seeds of food crops including edible oil seeds and seeds of fruit and vegetables.
2.    Cotton seeds
3.    Seeds of cattle fodder
4.    Jute seeds
5.    Seedlings, tubers, bulbs, rhizomes, roots, cuttings, all type of grafts and other vegetative propagated material for food crops or cattle fodder.

Multiplication and distribution of high quality seed of improved varieties is a crucial step in agricultural production of any country.

When an entry is identified by the workshop of the concerned project, the breeder begins the seed multiplication of the strain in the following crop season. The seed produced by the breeder after a strain is identified, but before it is released as a variety is termed as the “stock seed”. This seed is known as breeder seed after it is released and notified. In the crop season following notification foundation seed of newly released variety is produced. In the second crop season following the release of variety, certified seed of the variety is produced. Thus the farmer is able to obtain certified seed of a newly released variety for commercial cultivation only in the third crop season following in the notification of the variety. However the seed of such variety reach the farmer even before its release through mini-kit trials. Many other farmers would obtain the seeds from those farmers who conducted the mini kit trials and so on in the next two years. Thus an outstanding variety is likely to reach many farmers even before its certified seeds have been put on sale.

Abstract

Forestry in India is very important for its wood, fuel and many non-wood products which were being used from ancient times by our forefathers for different personal and commercial use. Farmers face lots of problem in forestry because of its long gestation period, dependence on nature, bulkiness of outputs, season oriented production, perishable in nature, lack of processing centres for value addition at farm and intermediate levels, price fluctuation of forestry products, forced sale/distress sale of tree growers, low wage rate to workers in forestry activities and farmers in sufficient knowledge on market information. Establishment of institutional setup to promote forestry is urgent in the recent times.

Onion growth, bulb initiation, yield, quality and storage life are strongly influenced by temperature, photoperiod, soil, moisture and crop establishment. Different cultivars require specific day lengths and temperature ranges, making regional variety selection and planting schedules essential. This chapter explains the environmental requirements of onion and the consequences of unsuitable conditions, including premature bolting, double bulbs, poor development and disease susceptibility. It examines soil preparation, planting geometry, direct seeding, transplanting and precision establishment. Modern approaches—including sensor-based environmental monitoring, Internet of Things systems, predictive modelling, precision seeding and machine-learning-supported input management—are presented as tools for improving uniformity, resource efficiency and climate adaptability.

Introduction

Since beginning of this century genetic diversity of agricultural crop has been lost due to several reasons (Marla, 2012). Genetic erosion is caused by human intervention, mono culture, green revolution especially due to commercialization of plant breeding. So there is urgent need to collect, conserve plant genetic & genomic resource for further use.

A seed bank stores seeds to preserve genetic diversity. There are many reasons to store seeds. One reason is to have on-hand the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, etc. of plants used in agriculture (i.e., crops or domesticated species). Another reason is to forestall loss of genetic diversity in rare or imperiled plant species in an effort to conserve biodiversity ex situ and in situ. Many plants that were used centuries ago by humans are used less frequently now and seed banks offer a way to preserve that historical and cultural value. Collections of seeds stored at constant low temperature and moisture guard against loss of genetic resources that are otherwise maintained in situ or in field collections. These alternative ‘living’ collections can be damaged by natural disasters, outbreaks of disease or war. Seed banks are considered seed libraries and contain valuable information about evolved strategies to combat plant stress or produce novel products. The work of seed banks spans decades and even centuries. Most seed banks are publicly funded and seeds are usually available for research that benefits the public.

Clonal crops belong to at least 34 families including herbs, shrubs, trees and vines. Clonal crop improvement dates back to 10,000 years ago. The diversity of clonal crops and their wild relatives are very significant but not yet fully understood and exploited. Many crops represent combination of sexual and clonal reproduction. Different parts of the clonal crops which may or may not be the same as consumed parts have been shaped as clonal propagules such as stem, setts, tuber, rhizome, corms and bulbs among others.

13.1 Introduction

Pomegranate (Punica granatum L.), an economically important fruit plant species, belongs to the family Punicaceae. It is an important fruit crop of arid and semiarid regions of the world and has been believed to be the symbol of fertility and abundance. Pomegranate is a highly remunerative crop for replacing subsistence farming and alleviating poverty. The plant is drought tolerant, winter hardy and can thrive well under desert condition. It is a good source of protein, carbohydrate, minerals, antioxidants, vitamins A, B and C, and has also been used in controlling diarrhoea, hyperacidity, tuberculosis, leprosy, abdominal pain and fever. Pomegranate juice contains antioxidants such as soluble polyphenols, tannins, anthocyanins and can be used in the treatment of cancer and chronic inflammation. It has enjoyed a reputation for its healthy dietetic and medicinal properties.

Crop improvement is a continuous process. Crop improvement aims to genetically enhance, enrich and empower the crop plants with superior performance, enhanced yield level, higher quality of food, nutritional, fodder, energy produce and adaptability to climate change and crop growing environments. The intrinsic virtues of the improved cultivars could be sustained mainly through the production of the quality assured seeds endowed with genetic capabilities. The quality assured seed delivery system is through the seed chain from the basic seeds through Nucleus-Breeder-Foundation-Certified seed. Quality seed production system need to be based on genetic, breeding and seed technological protocols including field and laboratory testing to ensure very high genetic purity, true to type and superiority.

3.1. INTRODUCTION

Heterosis is the superiority of the F1s over the parental forms. The term heterosis was first used by Shull (1910) to describe the interpretation of increased vigour, size, fruitfulness, speed of development, resistance to diseases and insect pests or some other characteristics manifested by out-breeding organisms as compared to corresponding inbreds. Exploitation of heterosis is gaining momentum due to increased yield, quality, uniformity, better desirable traits and management of biotic stresses. The future of most of the economic crops will be for hybrids for sustainable development of higher economic returns to the farmers. Sustainable increase in area under hybrid crops is witnessed by its popularity and adoption by the farmers.

Part I - Preliminary

1. Short title: These rules may be called the Seeds Rules, 1968
2. Definitions: In these rules, unless the contest otherwise requires.

Aims and Objectives

It has become evident that in order to achieve the food production targets of the future, a major effort will be required to enhance the seed replacement rates of various crops. This would require a major increase in the production of quality seeds, in which the private sector is expected to play a major role. At the same time, private and Public Sector Seed Organisations at both Central and State levels, will be expected to adopt economic pricing policies which would seek to realise the true cost of production. The creation of a facilitative climate for growth of a competitive and localised seed industry, encouragement of import of useful germplasm, and boosting of exports are core elements of the agricultural strategy of the new millennium.

Biotechnology will be a key factor in agricultural development in the coming decades. Genetic engineering/modification techniques hold enormous promise in developing crop varieties with a higher level of tolerance to biotic and abiotic stresses. A conducive atmosphere for application of frontier sciences in varietal development and for enhanced investments in research and development is a pressing requirement. At the same time, concerns relating to possible harm to human and animal health and bio-safety, as well as interests of farmers, must be addressed.

Globalization and economic liberalization have opened up new opportunities as well as challenges. The main objectives of the National Seeds Policy, therefore, are the provision of an appropriate climate for the seed industry to utilize available and prospective opportunities, safeguarding of the interests of Indian farmers and the conservation of agro-biodiversity. While unnecessary regulation needs to be dismantled, it must be ensured that gullible farmers are not exploited by unscrupulous elements. A regulatory system of a new genre is, therefore, needed, which will encompass quality assurance mechanisms coupled with facilitation of a vibrant and responsible seed industry.

Kharif onion helps maintain supply and stabilize prices when stored rabi onions become scarce. Its production is nevertheless challenged by high temperature, excessive rainfall, humidity, unsuitable varieties and limited availability of quality seed. Onion is biennial for seed production and requires bulb production followed by replanting for flowering and seed formation. Its protandrous flowers encourage cross-pollination, making adequate isolation and pollinator activity essential. This chapter explains short-day varietal requirements, bulb selection, vernalization, isolation, field management, pollination, harvesting, seed processing and storage. Improved infrastructure, organized production and farmer training are required to ensure continuous supplies of genetically pure, high-quality kharif onion seed.

1. INFLORESCENCE

An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches.

1.1. Types of inflorescence

Inflorescences can be simple or compound.

1.1.1. Simple inflorescence

Inflorescence of sessile disc florets forming the capitulum

1.1.1.1. Indeterminate

Indeterminate simple inflorescences are generally called racemose. The main kind of racemose inflorescence is the raceme. The other kind of racemose inflorescences can all be derived from this one by dilation, compression, swelling or reduction of the different axes. Some passage forms between the obvious ones are commonly admitted.

1. SEED

A seed is defined as a ‘mature ovule’ or a reproductive unit formed from fertilized ovule, consisting of an embryo, reserve food and a protective cover.

Seed is the basic input in agriculture upon which other inputs are applied. A good vigorous seed utilities all the resources and realized as a reasonable output to the grower. It is wealth to the farmer, it is the yesterday’s harvest and tomorrow’s hope. Good seed in good soil realize good yield.

Seeds exhibit a great range of variation in shape, size, colour and behaviour. The most essential factor for the success of plantation is the ready availability of quality seeds. The quality of seed is totally responsible for the future return / performance of each and every seedling.
