• The name Zoraptera, derived from the Greek “zor” meaning pure and “aptera” meaning wingless was given to the order before winged forms were discopvered.

• Members of the order Zoraptera are small (less than 4 mm) and usually found in rotting wood, under bark or in piles of old sawdust.

• They live in small aggregations (gregarious) and appear to scavenge on spores and mycelium of fungi, or occasionally, on mites and other small arthropods.

• polymorphism in populations; with blind, apterous individuals dominating during colony life, but populations produce eyed alates (individuals with wings) for dispersal and founding new colonies.

• males with a distinctive “mating hook” and unique mating behaviors.

• unique grooming behaviors

Adults

• Antennae 9-segmented (moniliform).

• Mouthparts mandibulate, hypognathous.

• Soft bodied, small (usually less than 3 mm).

• Wings often absent with reduced venation when present.

• Tarsi 2-segmented

• incomplete development (egg, nymph, adult)

INTRODUCTION

Orchids are the most beautiful flowers in God’s creation and have conquered the cut flower industry all over the world during the last few decades. They are most pampered of the plants, occupy top position among all flowering plants and are valued for cut flower production and as potted plant. They are known for their beautiful flowers, which exhibit an incredible range of size, shape and colour, long life of flowers on the plants and an amazingly long keeping quality which no other plant can claim.

Orchids are excellent for garden and can be grown in beds, pots, baskets, split hollows of bamboo pieces, etc. They are also suitable for interior decoration and remain fresh for many days. Before their aesthetic qualities were exploited, orchids were grown for their tubers which were considered as aphrodisiac. The leaves of Vanda roxburghii have been used against rheumatism in older days in India. Habenaria, a terrestrial genus of orchid also possess medicinal properties. Vanillin produced from Vanilla planifolia is used in flavouring industries. Orchids are used in indigenous system of medicine, particularly Ayurveda. Many of the orchid species contain alkaloids, which are important secondary metabolites. From Dendrobium nobile dendrobine and nobilonine are extracted. Similarly, laburnine from Liparis bicallosa, malaxine from Malaxis congesta and phalaenopsine from Phalaenopsis mannii are extracted. Pseudobulbs of Cymbidium madidum and Dendrobium speciosum are used as food.

Orchid industry in India is not as old as the cultivation and trade of other flowers. Our position in export market is very low as compared to south-east Asian countries like Thailand, Malaysia and Singapore, where orchid growing has become a multi-million dollar industry.

Abstract

Women empowerment means capacity of womenfolk to participate as equal partners in cultural, social, economic and political systems with much appreciated and gladly accepted by the society. Acceptance of unequal gender norms by women are still persisting in the society. Moreover, ignorance prevails in rural areas and subordination to men is considered as god-will by the womenfolk. Food, health and education are prioritized to boys and girls’ destiny is linked to surplus resource of the family if any, available. Gender inequality exists in every nation on the planet. Women’s disempowerment is all over the world, comprising countries of east and west so empowerment of women has become one of the most important concerns of 21st century’s world. More than one third of the world’s adults, most of them women, have no access to printed knowledge, to new skills or to technologies that would improve the quality of their lives and help them shape and adapt to social and economic change. There are 130 million children who are not enrolled in primary school and 70 per cent of them are girls. Women and girls around the world are more likely to live in poverty due to discriminatory and unjust economic policies, pervasive gender inequality, war and instability and climate change. Human society has to work for sexual and reproductive health and rights, freedom from violence, economic justice, and leadership as these are the critical building blocks for women’s rights. When a woman has these rights, she can be strong, safe, powerful, and heard. Cultural and religious factors are hurdles to women empowerment so the greatest need of the hour is to change the social attitude towards women. There is need to envision a world where all women, girls, and trans people have a voice and choice in the work they do. They are paid equal wages in safe and secure workplaces and they have access to justice and rights. Strengthening women’s leadership should be priority area because it is an integral part of social perception towards women status. The future of women’s human rights depends on a strong pipeline of diverse young women leaders, as well as on creating opportunities for leaders from different generations and movements to learn from each other. Long lists of international and national initiatives are available on the websites of various governments and United Nations but the tangible results are still awaited mainly because of poor/ half heartedly implementation.

Abstract

Indian agriculture witnessed a transformation in early seventies with green revolution in cereals. The Green Revolution resulted in a record grain output of 131 million tons in 1978-79. Yield per unit of farmland improved by more than 30 per cent between 1947 and 1979. This was because of introduction of high yielding varieties and use of agro-chemicals, particularly synthetic fertilizers. Farmers realized 3-4 times increment in their profit when high yielding varieties and chemical fertilizers were used in integration. Agriculture is the primary source of livelihood for about 58 per cent of India’s population. Gross Value Added by agriculture, forestry and fishing is estimated at Rs 17.67 trillion (US$ 274.23 billion) in FY18. The Indian food industry is poised for huge growth, increasing its contribution to world food trade every year due to its immense potential for value addition, particularly within the food processing industry. Food & Grocery retail market in India was worth US$ 380 billion in 2017, is the world’s sixth largest, with retail contributing 70 per cent of the sales. The Indian food processing industry accounts for 32 per cent of the country’s total food market, one of the largest industries in India and is ranked fifth in terms of production, consumption, export and expected growth. It contributes around 8.80 and 8.39 per cent of Gross Value Added (GVA) in Manufacturing and Agriculture respectively, 13 per cent of India’s exports and six per cent of total industrial investment. During 2017-18, food grain production is estimated at 279.51 million tons, with rice and wheat production in the country at 111.52 MT and 98.61 MT, respectively in the same period. Milk production stands at 165.4 million tons during FY17, while meat production is 7.4 million tons. India is the second largest fruit producer in the world. Production of horticulture crops is estimated at record 307.16 million tons (mt) in 2017-18 as per second advance estimates. Total agricultural exports from India grew at a CAGR of 16.45 per cent over FY10-18 to reach US$ 38.21 billion in FY18. In April-May 2018 agriculture exports were US$ 6.43 billion. India is the largest producer, consumer and exporter of spices and spice products. Spice exports from India reached US$ 3.1 billion in 2017-18. Tea exports from India reached a 36 year high of 240.68 million kgs in CY 2017 while coffee exports reached record 395,000 tons in 2017-18.

Introduction

Diazotrophs are phylogenetically diverse microbes spanning over various classes varying vastly on basis of physiological properties (Young, 1992), include various phototrophic microorganisms aerobic phototrophic Cyanobacteria (Vaishampayan et al, 2001), anaerobic purple-sulfur phototrophs like Chromatium, and green-sulfur phototrophs, e.g. Chlorobium, Rhodopseudomonas; chemolithotrophs Alcaligenes, Thiobacillus, Methanosarcina, Methanobacterium, Desulfovibrio or Azospirillum lipoferum and heterotrophic bacterial anaerobes (Clostridium), microaerophiles (Herbaspirillum), and aerobes (Azotobacter). Free-living aerobic nitrogen fixing bacterial genera found in soil include obligate aerobes as Azotobacter, Beijerinckia, Derxia, Achromobacter, Mycobacterium, Arthrobacter and Bacillus but the majority are microaerophilic (e.g. Azospirillum, Herbaspirillum) or facultative and obligate anaerobes (e.g. Klebsiella, Aerobacter, Desulfovibrios, Rhodospirillum, Clostridium, Erwinia).

Abstract

The per capita availability of fresh water in the World is continuously decreasing. It is reported that in the World about 69 percent of total water resources developed are used for irrigation, 23 percent for industries and the balance is used by the domestic sector. About 60 percent to 70 percent of water used in domestic sector is returned as waste water. Substantial quantities of water used by industries are also returned. To meet the increased food requirements of the global population, there is constant pressure for increase in food production. Since, agricultural productivity depends on availability of water; there is increased demand of water for irrigated agriculture. On the other hand, due to increased demand of water for other sectors, quantum available for irrigation sector is getting reduced. So, for meeting the increased irrigation demand, it is necessary to economise the use of water for irrigation by adopting improved technologies and improving the water use efficiencies. 

INTRODUCTION

Tribulus terrestris L. (Gokhru) is an important industrial herb, belonging to family Zygophyllaceae which includes 285 species representing around two dozen genera. Members of this family are distributed in tropical and warm climates. Most species are shrubs, but some grow as small trees or herbs. T. terrestris is a mat forming plant that grows extensively in warm and dry areas all over the world. In China, India, Greece and other parts of the world, the species finds wide application in folk medicine, in polyherbal formulations and as food supplement for physical rejuvenation, to enhance muscle strength, sexual potency, etc. Amidst many positive claims, clinical trials are recommended to evaluate its reported toxicity in animals.

Introduction

• The green revolution of the 1960s and 1970s ended chronic food deficits and while cereals still command the attention of policy makers, fruit production has surged impressively, making India the second largest global producer behind China.

• Annual growth in horticulture has seen fruit production grow at faster rate and constitute the larger segment of agriculture. • No doubt, there has been manifold increase in area, production and productivity but when we compare the productivity of various major fruit crops with other developed countries, our productivity is very low.

• This may be mainly attributed by non-availability of quality planting material and seeds, existence of old unproductive seedling orchards, small and unirrigated land holdings, use of inferior genetic stocks/ varieties/hybrids, poor management and non-adoption of package of practices, high incidence of pest and diseases, heavy pre and post harvest losses and lack of trained human resource.

• To meet increasing demand the productivity per unit area per unit time and per unit investment has to be increased from limited land resources, where production and supply of quality planting material of elite varieties is one such important factor that can bring tremendous improvement in production, productivity and higher economic returns to farmers.

• This may be mainly attributed by non-availability of quality planting material and seeds, existence of old unproductive seedling orchards, small and unirrigated land holdings, use of inferior genetic stocks/ varieties/hybrids, poor management and non-adoption of package of practices, high incidence of pest and diseases, heavy pre and post harvest losses and lack of trained human resource.

INTRODUCTION

In India, medicinal plants have traditionally occupied an important place in the socio-cultural, spiritual and health related aspects of peoples’ life. As much as 34% (ca. 6000) of total plant wealth have some known medicinal value (Ved, 2008). The genus Ephedra is one such important group of medicinal plants, from which the drug Ephedrine and a range of medicinally active compounds such as ephedrine, pseudoephedrine, norephedrine, norpseudoephedrine, methyl ephedrine, methyl pseudoephedrine, alkaloids, phenols, terpenoids are obtained. Owing to its medicinal properties, genus Ephedra is in high demand by pharmaceutical industries. It is currently facing heavy extraction pressure from its restricted habitat in the wild, and utterly lacks effective proper conservation and management efforts. For long-term conservation management of this genus, a better and comprehensive understanding of the species remains a top priority, for which detailed studies on its biology, habitat ecology, and agro-technology are required.

Refrigeration mean cooling i.e. lower the temperature by artificial means. It is a process of attaining lower temperature of the space or product below the surrounding temperature. It further involves maintaining the lower temperature achieved.

2.1. Concept of review of literature

Research is a continuous process. For any scientific investigation, previous f indings provide basis to the research. It also helps to know the previous research work done in that area and acts as a torch for the new researchers. The review of literature is one of the important aspects in the research process. It helps the researcher to keep his work going in right and appropriate direction. To point out prior research in the area of interest and how our findings connect to past studies, a review of the literature is conducted. The proposed study is new in its subject treatment. However, an attempt is made here to put together some of the closely related research findings in the area.

Abstract

Space, water and labour have become limiting factors in vegetable production. Moreover, production of off-season vegetables during period of demand fetches better returns. Vegetable forcing for year round production has become a necessity in urban and peri-urban olericulture. With use of pesticides, fungicides, weedicides and chemical fertilizers, health hazards have become visible. Being treated as a field crop, vegetables are exposed to vagaries of weather and floods and droughts take heavy toll. Research on protected cultivation in India is limited but for attempts by private seed companies and enterprising farmers in Karnataka, Maharashtra, Haryana and Punjab. More emphasis is given to tomato, cucumber, capsicum, lettuce and beans. Breeding for varieties suited for protected cultivation is a recent innovation in public sector laboratories. Now there are parthenocarpic cucumbers, tomatoes and capsicum especially to suit protected cultivation. The first four vegetable varieties were developed and released by Uttarakhand State Varieties Release Committee for Horticultural Crops during 2011. These varieties namely Pant Polyhouse Hybrid Tomato -1 , Pant Polyhouse Tomato -2 in tomato and Pant Parthenocarpic cucumber -2 and Pant Parthenocarpic Cucumber -3 in cucumber. These varieties were delivered to ployhouse farmers cross the country.

Introduction

Research setting is basically a functional social ecology along with research objectives and condition wherein all possible socio-economic and communication processes are generated, and again gets regenerated. The researcher seeks to throw a spotlight on the implications and behavioral patterns of people who reside in the subject region and who are usual of the greater community. In this chapter, an in-depth review of the socio-demographic background of the local population in a rural setting has been provided.

4.1. Area of the study

The present research study was taken up in two states, Tamil Nadu and West Bengal.

Introduction

In ruminants,nutritional studies are very complicated unlike non ruminants where it is quite simple. In non-ruminants, analysis of feed taken and faeces voided by the animal gives overall picture of digestion and nutrient availability to the animal. In ruminants, since it has a complex microbial digestive system (rumen) within the animal digestive system, the analysis of the feed taken and faeces voided will not express the whole processes in the GI tract of the animal. To have complete picture, it is necessary to study at the site of microbial digestion (rumen). For such study, samples from the rumen have to be drawn and analyzed for metabolities, microbial enzymes etc.

Apple (Malus x domestica Borkh) is the most widely grown temperate fruit of the world considered as king of temperate fruit. It is one of the most delicious fruit rich in carbohydrates, minerals like calcium, phosphorus, iron, potassium, vitamin B6 and low in calories. Apples are extremely rich in important antioxidants, flavanoids, and dietary fiber. Apple is recommended to reduce the incidence of dental caries, and the phytonutrients and antioxidants may help reduce the risk of developing cancer, hypertension, diabetes and heart disease. Apple is chiefly used as table fruit. The various processed product like juices, jelly, preserve, canned slices, wine, concentrated juice, cider and powder are prepared from apple fruit.

Abstract

The nutrition of tobacco plants relies upon the plant genotypic variation and soil characteristics which also influence the various microflora that inhabit the rhizosphere. The investigations were aimed to analyze the role of native and inoculated plant growth promoting bacteria on the uptake of major plant nutrients viz., nitrogen, phosphorus and potassium and also their supportive nature in reducing the infection caused by  Pythium aphanidermatum, the damping-off fungus of tobacco in nursery. Rhizosphere microorganisms include PGPR viz., Azotobacter, Azospirillum, Pseudomonas and Bacillus, AM fungi and Streptomyces. The addition of these microbes as bioinoculants in tobacco integrated nutrient and disease management resulted in better quality tobacco worth premium price.

Abstract

Cyanobacteria comprise a group of photosynthetic prokaryotes, which exhibit versatility in their morphological, biochemical and molecular characteristics and represent an untapped source of novel metabolites and genes. Their structural-functional flexibility makes them successful in diverse and extreme environments including high temperatures or levels of UV light and salinity, and co-exist in symbiotic/parasitic/mutualistic associations with various members of Plant and Animal kingdom. The intracellular colonization of cyanobacteria in wheat and rice roots and their potential as plant growth promoting agents for several crops, besides rice, has led to the deployment of novel formulations of cyanobacteria and agriculturally useful bacteria as biofilms and disease suppressive options in field studies.

It is well recognized that sustainable management and sustainable livelihoods are inseparable. If neglected and if the present trends are not corrected in time, everyone’s future is threated. On the other hand, there is increasing recognition of living examples and demonstrated evidences of how the eco agricultural practices can help provide a solution to some of the major problems of today and tomorrow. Also, the main stream international agencies are emphasizing that agro-ecological approaches are the way forward. What the policy makers, farmers and people would like to know is How !it has been our experience that in most countries of the developing world the answer to ‘How’ of eco-agricultural is being demanded!
