Introduction

Quality of Work Life (QWL) is a popular concept among the organizations. Work is an essential part of everyday human life. Work influences the overall quality of life. Human resources are one of the main assets of any organization. Quality of work life (QWL) is one of the important subsystems of human resource management. There are economic, social, psychological and organizational aspects of work life. Many new subsystems are being added to human resource management with employees’ changing needs, culture, expectations, and work environment.

Seed quality is the possession of seed that is genetically pure and physically homogeneous, coupled with health and wellness.

A seed is the first genetic material that becomes the basis for future agriculture and seeds are the basic building blocks of agriculture. A great deal of farming has been modernized by technology, but without a regular and steady supply of high quality seed, yields would be drastically reduced and crop quality would decrease as well. The production of horticultural and agronomic crops depends largely on quality seed. For farmers, seed characteristics such as genetic purity, germination percentage, vigor, and appearance have a significant effect on yield. Every professional seed producer strives to achieve and maintain high seed quality.

Single seed descent (SSD) method of breeding is applicable to self-pollinated crops. The method of single seed descent (SSD) was born out of a need to speed up the breeding programme by rapidly inbreeding a population prior to initiating individual plant selection and evaluation while reducing a loss of genotypes during the segregating generations. SSD procedure is based on advancing generations through single seed from each plant in each generation. This separates the inbreeding phase from the selection phase and the population reaches F6 generation faster. This procedure carries forward maximum number of F2 plants to a stage near homozygosity, i.e. F6. It was first proposed by C. H. Goulden in 1941 when he obtained the F6 generation in two years by reducing the number of generations grown from a plant to one or two while conducting multiple plantings per year using greenhouse and off-season planting. H. W. Johnson and R. L. Bernard described the procedure of harvesting a single seed per plant for soybean in 1962. However, it was C.A. Brim who, in 1966, provided a formal description of the procedure of single seed descent, calling it a modified pedigree method.

The feeding is an important operation in aquaculture, it is the process of providing nutritious supplements or live feeds to the culture animal. The equipment used for this purpose is named as feeders. Equipment that is connected with fish feeding can be divided into three major groups, as follows

• A title should be able to talk. It ought to make a point that both informs and amuses the audience.

• A headline needs to be concise and sum up the story.

• A headline should engage readers and entice them to read the material behind it.

• Make use of recognisable acronyms.

• Assist in setting the publication’s general tone.

• The headline ought to be assertive and upbeat.

• Function as a visual component on the page.

Choosing and designing news headlines

• If necessary, the headline should be written in all capital letters.

• Double-tick the letter that needs to be capitalised.

Introduction

Quality seed plays seminal role in augmenting agricultural production as well as productivity. Only by using good quality seeds, productivity can be enhanced up to the tune of 15-20 per cent alone, but under optimum management, the increment may touch upon up to 45 per cent depending upon the crops since the efficiency and efficacy of all other inputs in the production technology gamut are contingent upon the quality of seeds being used. Since antiquity the importance of quality seed to enhance agricultural productivity is well evident as mentioned in old testimonials, literatures, scriptures, treatises, epics, and many other ancient documents.

Seed quality is the major decisive factor governing stand establishment of any crop and thus having immense importance and bears utmost priority in case of high value, low volume crops like vegetables in particular and for high volume low value crops in general for enhanced productivity and production as well (Mandal et al., 2015). A number of diverse materials/ treatments at varying doses have been used to increase the rate and uniformity of seedling emergence in wheat and rice, which are generally categorized for seed enhancement, which is a kind of value addition.

Seed enhancement may be defined as post-harvest treatments that improve germination and seedling growth or facilitate the delivery of seeds and other inputs/materials required at the time of sowing smoothly. Seed enhancement technology predominantly possess a central objective to further improve seed performance by treating with specific additives/ chemical/ organics/ botanicals, etc. under very specific regimes and with the aid of certain planting equipments to grow uniform crop obviously to harness higher productivity and production (Halmer, 2006). Various techniques have been employed to assure superior performance of additives in different crops and most have been found to have immense commercial application (TeKrony, 2006). This includes three general areas of enhancement: pre sowing hydration treatment (priming), coating, pelleting technologies and seed conditioning.

Abstract

This chapter presents the principle of fluidisation and its use in drying of food materials. Being a convective drying process, capacity and kinetics are limited by process conditions and material properties. The influences are discussed as well as presenting the main equations that describe drying in fluidised beds. The main focus lies on hot gas drying, additionally superheated steam drying as well as atmospheric fluidised bed freeze drying and microwave-assisted fluidised bed drying are presented and discussed.

Introduction

Seed as an input is the precursor for agricultural development as it alone can guarantee 20-30 per cent share of crop productivity (Koudinya and Kumar, 2014). Rigveda, the world’s most ancient scripture available, prescribes the importance of seeds as “Subeejam Sukshetre Jayate Sampadyate” which literally means, “A good seed in a good field can lead to the prosperity and posterity of the entire human race”. Seed production is indeed important to take care of a country’s food and nutritional security needs. At the same time, seed export across countries is vital for ensuring competitiveness in the domestic seed industry besides generating employment and valuable foreign exchange which in turn can be used for scaling up the seed sector’s efficiency itself (Poonia, 2013). As a matter of fact, seed trade is one of the reasons for huge advances made in the Indian seed industry through development and exchange of genetic transformation, marker-assisted breeding and nanotechnology (Nandi et al., 2013). As of 2014-15, global seed industry has reached USD 45 billion in which international seed export alone was worth USD 10 billion. Further, with the estimated growth rate of 9.2 per cent during 2015-2020, the world seed business is expected to be over USD 92 billion. Presently, USA, China, France, Netherlands and Brazil are the top markets comprising more than 66 per cent of the global share in seed trade. Corn, soybean and vegetables account for more than 75 per cent of the total global seed market volume. As of 2014-15, the value of the Asian vegetable seed market was USD 6.75 billion in which China had a major share (41 per cent) and the Indian share was around 7 per cent. Moreover, the world vegetable seed market alone is expected to grow at the rate of 7 -8 per cent per annum and reach USD 8.8 billion by the year 2020 (Parashar and Kumar, 2016).

Introduction

Seed is a critical and vital input that draws an explicit line between the success and failure of any agricultural production programme. In fact progressive history of agriculture has been a history of seed development and production. The mankind has been attempting to select better seed and employ better seed production techniques volitionally or in-volitionally ever since it divested nomadic life for the settled one. Initial attempts were confined to selection of useful crops followed by selection of better sorts and land races among the available native genetic resources. The introductions, hybridization followed by selection of better types and modern breeding tools inclusive biotechnological interventions have been extensively employed to breed better seed. Considering that research in crop improvement can turn little stone unless the quality seed with desired attributes is made available to the farmers. Government of India set up enforcement of provisions of Seed Act, 1966 for certification of seed as per prescribed minimum standards. Central Seed Certification Board was established in 1972 to exhort the central and state governments for producing genetically and physically pure and physiologically viable seed. The seed production programmes and rules were progressively honed to meet the ground situations. Initially the seed was considered as the exclusive bastion of public sector but the private sector got actively involved in seed production. WTO the seed still became a very open subject and the Seed Act was modified in 1988 and 2001 to permit import and export of quality seed, respectively. Despite of all these positive developments in seed sector, the availability of seed is still far from satisfactory. As on today private sector dabbles in low volume high cost seed due to economics and storage factors but the high volume less cost is still a virgin for private sector and is predominantly done by the public sector. Crop improvement is no more an art and science of improving hereditary of crop plants but has become a starker and competitive business under which the stronger would survive and the weaker get eliminated.

Business was abysmally shattered at the terminal end of the Second World War. This forced some nations to sign some tariff related global

Organic agriculture or farming is very much native to India. Whosoever tries to write a history of organic farming will have to refer India and China. The farmers of these two countries are farmers of 40 centuries and it is organic farming that sustained them. This concept of organic farming is based on following principles:

• Nature is the best role model for farming, since it does not use any inputs nor demand unreasonable quantities of water.
• The entire system is based on intimate understanding of nature’s ways. The system does not believe in mining of the soil of its nutrients and do not degrade it in any way for today’s needs.
• The soil in this system is a living entity.
• The soil’s living population of microbes and other organisms are significant contributors to its fertility on a sustained basis and must be protected and nurtured at all cost.
• The total environment of the soil, from soil structure to soil cover is more important.

Abstract

Mushrooms are the fruiting bodies of fungi, a group of organism that is different from fruits and vegetables. They are a rich source of good quality protein having more essential amino acids and vitamins with low calories. There are about six commonly known edible mushrooms throughout the world with button mushroom (Agaricus bisporous) being the most familiar and commercially important variety. Mushroom is a highly perishable product with a shelf life limiting to a few days. Soon after harvest, it starts to undergo physiological disorders like shriveling, wilting, liquefaction, browning, textural as well as weight losses and flavour changes. The main responsible factors for the quality deterioration after harvest are respiration rate, browning, bacterial spoilage of mushrooms, temperature and relative humidity. Because of its limited shelf life under ambient conditions of temperature and humidity, the preservation of mushrooms is a matter of concern. Various techniques have been involved in the extension of shelf life of mushrooms including chemical treatments, cooling, modified and controlled atmospheric storage, radiation, drying etc. Drying is one of the most accepted and effective methods for the long term storage of mushrooms. Mushrooms preserved by drying have a pleasant flavour and are used as an important ingredient in several food formulations including salads, instant soups, meats and rice dishes. Various drying processes like sun drying, hot air drying, freeze drying, vacuum drying etc. can be used for the long term storage of mushrooms. As mushrooms are sensitive to temperature, determining the right drying method is the key for the successful and effective operation of the system. The different operating conditions involved in various methods of drying affect product quality considerably. The effect of drying methods on the process and the quality of the dried mushroom is explained in detail in this chapter.

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).

Introduction

Seed pathology has been recognized as its own specialization for a relatively brief time, and the term “Seed Pathology” was first coined by Mary Noble in the 1940 (Agarwal and Sinclair, 1997). Seed pathology is an essential part of seed technology as well as a sub discipline of plant pathology. According toAgarwal and Sinclair (1997), it may be defined as the study of seed borne disease and pathogens carried with seed. It also includes studies on the mechanisms of seed infection, seed transmission, the role of seed borne inoculum in disease development, methods for the detection of seed borne pathogens and non-pathogens, seed certification standards, mycotoxins and mycotoxicoses, and various methods for control of seed borne disease. Seed pathology includes the study of diseases and deterioration caused by bacteria, fungi, nematodes, viroids, viruses, physiological and mechanical disorders.

Neergaard Paul is considered the father of seed pathology. He was one of the founding father and later served as Director of the Danish Government Institute of Seed Pathology for Developing Countries, Copenhagen, Denmark, from 1956 to 1974. He served as the Chairman of the Plant Disease Committee of the International Seed testing Association (ISTA). During his tenure as Chair of ISTA, he helped standardize methods for the detection of seed borne fungi.Neergaard (1977) authored a two-volume text entitled “A Seed Pathology”. This text has served as a reference and teaching standard for the science of seed pathology throughout the world (Agarwal and Sinclair, 1997). This text focused on a wide variety of seed pathology issues, ranging from the economic significance of seed borne diseases to the assessment of seed borne inoculum.

Abstract

Vitamin C is one of the most important phytochemicals and can be found in almost all fruits and vegetables. Since it covers almost all eventualities, being water solute and prone to leaching from cells, thermally labile (one of the most labile vitamins), pH-, metal ion-, light-sensitive, as well as readily oxidizable by ascorbic acid oxidase, vitamin C is selected as the most frequently measured nutrient to evaluate the nutrients loss during thermal processing. It is generally accepted that if vitamin C is well preserved, the other nutrients are also well retained. Higher retention of vitamin C in processed products is highly desired. Herein this chapter reviews the degradation mechanism and kinetics of vitamin C of fruits and vegetables during thermal processing, such as blanching, drying, cooking and frying. It starts with an overview of the functions of vitamin C in human’s health. Then the current status for understanding of the degradation kinetics of vitamin C during thermal processing was outlined, followed by the discussion of its degradation mechanism. At last, potential strategies or alternatives to keep vitamin C are identified and discussed.

Introduction

Thar Desert is unique both from floristic and climatic parameters. Biodiversity in this region survives on a very/ fragile ecosysytem under a highly hostile environment. Major area consists of dry undulating mass of loose sand, thus, leading to shifting sand dunes. The sandy plain is full of sand-hills with serve as low depressions where salt and soda are deposited after drying. The whole area is inhospitable and sterile. Trees are rather a few and far between (Bhandari, 2005).

The Thar Desert of western India is known for its rich and ancient culture system and traditions. The communities have long been part of the Thar Desert ecosystem and have evolved specific strategies to live in harmony with its hostile environment. Orans have remained mainstay in balancing this arid ecosystem. Man of this region has never been greedy as he is today. Orans were repositories of ancient system of gene pool conservation. But, there are unregulated encroachment on the marginal lands and over-exploitation of groundwater resources. Orans has been part and parcel of the lifestyle of the Thar Desert inhabitants. Orans are used to provide vital grazing land for livestock, water, minor forest produce, medicinal plants and green cover for the villages. They were worshipped as devbhumi. Orans preserve the endemic, endangered or threatened species, medicinal plants and wild variety of cultivars found.

Lignieres and Spitz first isolated Actinobacillus from the cattle with actinomycosis like condition in Argentina in 1902. The findings were also confirmed by Nocard in 1902. Later the isolated bacterium from the cattle was named as Actinobacillus lignieresii in memory of Lignieres.

Pfeiffer (1892) first isolated Haemophilus influenzae as a cause of human influenza and it is also known as ‘Pfeiffer’s bacillus’. Other workers isolated and described different species of the genus Haemophilus from animals and birds. In 1903, Friedberger, a research assistant of Pfeiffer, isolated similar kind of bacteria from prepuce of dogs which was described later as Haemophilus canis. In 1925, Mitchell isolated Haemophilus ovis from the respiratory tract of sheep. Lewis and Shope (1931) isolated and illustrated Haemophilus suis from the infected pigs. Glasser found the association between fibrinous serositis, polyarthritis in pigs (Glasser’s disease) and a small gram-negative rod as early as 1910, later became known as Haemophilus parasuis. The bacteria was first isolated by Hjarre and Wramby in 1943. De Blieck (1931) isolated a hemophilic bacterium from the birds suffering with ‘infectious coryza’ and named the bacteria as Bacillus haemoglobinophilus coryzae gallinarum. Later it became known as Haemophilus paragallinarum (Avibacterium paragallinarum).

Cohn (1875) first observed and described a branching filamentous microorganism in the ‘concretions’ (coagulated mass) taken from a lacrimal canal, later identified as Actinomyces israelii. Bollinger first reported the yellow granules in jaw tissues of the cattle in 1877 and established the significance of the bacteria as the etiological agent. In 1878, Israel described the first human case. In 1879, Hartz observed the microscopic appearance of granules of Actinomyces and suggested the name Actinomyces bovis. Mosselman & Lihnaux (1890) and Wolf & Israel (1891) first isolated the bacteria in artificial laboratory media from lumpy jaw cases of cattle and human actinomycosis, respectively.

Limitations of Bacteria

• Normally genetically engineered bacteria are very useful for the large scale production of valuable eukaryotic proteins.
• Bacteria grow rapidly, They grow on relatively simple media, they are easy to handle, they are easily transformed, they can grow on wide range of substrates, they multiply, fast, they contain simple and well characterized genome, they can be easily modified but even though, they have their own problems…

1. Bacteria do not have intrudes and so they do not have any system or machinery to remove introns.
2. Many eukaryotic proteins undergo different types of modifications after they are produced. These modifications are known as “post translation al modifications”.
3. Each bacterial cell usually contains many copies of the plasmid but there is no mechanism to ensure the equal distribution of plasmids in daughter cells.

6.1 Introduction

This chapter presents the impact evaluation (summative) of the vegetable IPM programme that was conducted by the Central Integrated Pest Management Centre (CIPMC) Jammu in the sub-tropical areas of Jammu, Samba and Kathua districts. These districts were selected purposively as the maximum numbers of IPM-FFS were conducted by CIPMC in these three districts. Ex-post facto research design (with/without) was employed for conducting the impact evaluation of vegetable IPM-FFS programmes conducted between 2003-04 and 2007-08. This design uses a pre-existing situation as the treatment instead of actual manipulation of the variables. An ex post facto study uses a comparable site as the control to find the programme effects.

An Ex-post facto research is a systematic empirical inquiry in which the scientist does not have direct control of independent variables because their manifestations have already occurred or because they are inherently not manipulated. Inferences about relations among variables are made, without direct intervention, from co commitment variation of independent and dependent variables. This kind of research is based on a scientific and analytical examination of dependent and independent variables. Independent variables are studied in retrospect for seeking possible and plausible relations and the likely effects that the changes in independent variables produce on a single or a set of dependent variables. The ex-post facto design was also used by Peshin and Kalra (1998); Reddy (2006); Maraddi et al., (2007) while evaluating the IPM programmes. The indicators for evaluation of the IPM-FFS programme were selected based on the requirements of the research design.

Family: Acanthaceae

Flowering: September-December

Fruiting: January-April

Botanical description: The plant is an erect annual herb extremely bitter in taste (all parts of the plant). It grows erect to a height of 1-4 ft. with dark stem. The leaves are glabrous, lanceolate, pinnate, with 8.0 cm long and 2.5 cm broad. Flowers of the plant are small, white-purple or spotted purple in colour, spreading axillary and terminal racemes or panicles and acute at both ends. Seeds numerous, sub quadrate and yellowish brown in colour.

1. Botanical name : Antidesma acidum Ritz.

2. Family : Phyllanthaceae

3. Common Name : Antidesma

4. Name in Indian languages : Amati (Marathi), Himalcherry (Hindi), Kareekome (Kannada), Airyoporiyan (Malayalam), Aanepooi (Telugu), Nolaidali (Tamil).

5. Description

Antidesma acidum is a shrub or a tree growing up to 10 metres tall. The bole, which usually branches from near the base, can be 10cm in diameter. It is found in dry deciduous, deciduous and evergreen forest at forest edges or in open spaces and bamboo thickets; or half-shady habitats associated with dipterocarps, pine, oak. It is often disturbed, much degraded or frequently burnt vegetation.

1. Introduction

Antioxidants are defined as molecules which can be safely interact with free radicals and terminate the chain reaction before vital molecules are damaged (Nidhi and Gaurav, 2012). Naturally occurring antioxidants to replace synthetic antioxidants which are being restricted due to their carcinogenicity (Abdel Hameed, 2009). The antioxidant phytochemicals such as polyphenols, flavanoids and related compounds found in medicinal plants have received increasing attention for their potential role in prevention of human diseases (Upadhyay et al., 2010).
 
The genus Ophiorrhiza belongs to the family Rubiaceae and consists of about 150 species and distributed in tropical and subtropical Asia. Species of Ophiorrhiza are economically important and many of these species contain a high value anticancerous compound, a cytotoxic alkaloid camptothecin and other valuable alkaloids. Ophiorrhiza pectinata Arn. is a herbaceous plant and is distributed over peninsular India and Srilanka. A preliminary study conducted in O. pectinata also contains this important alkaloid (0.0040mg/g dry wt). Leaves and stem contain traces of hydrocyanic acid. The main objective of the present study is to evaluate the antioxidant and radical scavenging property of the chloroform methanol and water extract of whole plant of O. pectinata.
