Protected cultivation can be defined as a cropping technique wherein the micro-climate surrounding the plant is controlled partially or fully as per the requirement of the plant species during their growth period. This cropping technique is the most modern approach to grow different horticultural crops mainly, vegetable crops and flowers for enhancement of both productivity and product quality. This technology has spread extensively the world over in the last few decades. This technology involves the cultivation of different crops particularly, horticultural crops in a controlled environment wherein the environmental parameters like the temperature, humidity, light, soil, water, plant nutrition, etc. are manipulated for enhancement of production as well as product quality even during off-season which ensures additional return to the growers.

Physical and chemical techniques have been applied either alone or in combination with certain cultural practices to enhance the effectiveness of reducing pathogen inoculums and consequent reduction in disease incidence. Seeds and asexually propagated planting materials have been treated with physical and / or chemical methods in order to eliminate the pathogens from them and to build up disease-free stocks. Physical and chemical methods may be applied to reduce the inoculum present in plant debris as well as in the soil and water. Enough attention has not been bestowed to tackle the pathogens that may exist on fallen leaves or shoots from which infectible spores may be produced later.

Crop husbandry includes various cultural practices aimed at enhancing yields from a given unit of land. To achieve this aim, practices such as growing high yielding cultivars which are fertilizer responsive, high density planting and application of large quantities of different nutrients and frequent application of pesticides have been followed. Consequently these practices have been found to be responsible for some problems which were not associated with crops raised by adopting traditional agricultural practices. Thus the benefits of modern methods appeared to be lost, because of the unforeseen problems for which the effective solution have to be found out. Various methods that could be dovetailed with regular cultural practices have been shown to be useful in either reducing the existing pathogen inoculum or avoiding build up of inoculum in the field.

Plant diseases caused by microbial pathogens have been managed by using different methods which need to be applied every year or season, when the susceptible cultivars are grown. These methods are grouped as nongenetic methods, since no change in the host genome can be expected, when physical, chemical, cultural or biological control methods are employed. On the hand, if a change in the host genome is accomplished by either conventional breeding techniques or by biotechnological procedures, the progeny may show higher level of resistance to the target pathogen (s). The genotype or cultivar thus generated will show resistance during subsequent seasons till a new race of pathogen capable of overcoming the effects of resistance gene(s) is produced. Disease management through host resistance is considered as the most preferable option because of several advantages. Crop production is less expensive ; there is no need to apply any procedure for every crop season ; and chances of environmental pollution are absent, when a crop cultivar resistant to the disease (s) is grown. In addition, the build up of pathogen population is progressively reduced. Management of diseases by cultivating resistant varieties may be more effective and economical, if the benefits accumulating over a period of time and enlarging area with lapse of time are taken into consideration.

Several fungal and bacterial pathogens that are airborne settle on the foliar tissues of susceptible host plant species and initiate infection which spreads to other plant parts later. Fungal pathogens cause different types of leaf spots, downy mildews, powdery mildews and rust diseases commonly on various crops. The bacterial pathogens induce blights and rot diseases.

INTRODUCTION

Education, as is widely argued is a method of knowledge sharing and distance education is a concept in education that is widely prevalent. Several people around the world qualify themselves through this mode of education. Though widely popular, it has its limitations with respect to production, reproduction and distribution costs, however, the role of distance education is shifting (Caswell et al. 2008). This shift is accomplished with the help of technology, which reduces and almost nullifies the reproduction costs (Caswell et al. 2008). This is a step towards making the quality of life of learners around the world improve (Caswell et al. 2008). Further as Caswell et al. (2008), rightly quote that, this is also the beginning of a movement to ensure the Universal Declaration of Human Rights article 26, which declares that everyone has the right to education and “technical and professional education shall be made generally available” (United Nations, 1948).

Distance learning made possible through the help of technology specifically the internet or e-learning is not a new concept. Several individual course materials are available online (Baldi et al. 2003). However, systematically organizing and structuring the academic course materials from different disciplines and easy retrieval of such information is a sign of innovation (Baldi et al. 2003). This innovation which is currently made possible through initiatives of different Universities, institutes of learning and organizations is popularly titled Open Course Ware (OCW).

The role of fringe cannot be ignored in the city development process. It is interesting to study the pattern and characteristics of fringe in developing cities. The chapter focuses on the phenomenon of urban fringe of Pune and also discusses strategies for further development. The study deals with some of the variables of change like demographic pattern, land use, and infrastructure in fringe area villages.

Historical Growth of Pune City

Pune’s origin date back at least two thousand years, it was a small settlement called ‘Kasbe’ and developed into a metropolitan region over the period of time. Its basic unit of development can be identified as ‘wada’ - a traditional house. In due time these developed into ‘peths’, which were planned complexes including residences of all types, commercial areas, parks, playgrounds, police station etc.

During 13^th to 17^th century, the city was under the control of Muslim rulers. Pune gained importance in 1630s, when it was declared as capital of Maratha kingdom. Pune’s importance grew in this period and many peths were developed to cope with the increasing requirements. The town changed hands between Maratha and Mughals before the British gained control of it in 1818. The Pune cantonment and Kirkee cantonment were established by British to guard the entry points. Development of cantonment areas started in this period and Parsi families constructed spacious bungalows which gave an image to the city.

Sustainable management of soil resources is essential for food, nutritional and economic security of the country. The continued degradation of soil resources is considered an important factor in lowering the total and partial factor productivity of agriculture in the country. The process like soil erosion, nutrient loss, water logging, desertification, acidification, compaction, crusting, salinization and soil contamination affect food and environmental security in most parts of the country. The future agricultural growth at higher rate cannot be sustained with a deteriorating soil resource base. We need to monitor the quality of soil resources and devise appropriate management strategies for sustainable crop production without deteriorating the environment.

In India, several agencies like National Commission on Agriculture (NCA), Ministry of Agriculture (Soil and Water conservation Division), Society for Promotion of Waste lands Development (SPWD), NBSS&LUP, Nagpur have been constantly inventorizing and characterizing soil resource for drawing up land use and development plans at National and State levels. However, there is a great variance in estimates due to differences in approaches and criteria for assessment. For an example,the total degraded land as estimated by NCA is 148.09 Mha as against, 175.0 Mha by Ministry of Agriculture (Soil and water conservation Division), 129.58 Mha by SPWD and 187.7 Mha by NBSS&LUP, Nagpur.

In soil profile development, we focused on vertical variability in soils - the differences among soil horizons. In this chapter we focused on horizontal variability- how soils differ from place to place across the landscape. Spatial variations in soil properties occurs across distances having geographic meaning for land management-from a few meters to many kilometers. We need to monitor regularly the status of our soil resources employing modern technologies to refine our understanding about them and renew our commitment to their preservation. The applications of Remote Sensing (RS), Geographical Information Systems (GIS) and Global Positioning System (GPS) have greater opportunities to offer in this regard.

Sustainable management of soil and water resources is essential for food, nutritional and environmental security of the country. The total and partial factor productivity of agricultures in India declined over years because of continued degradation of natural resources. The process leading to land degradation are generally triggered by excessive use of land and water resources to meet the growing demand of population for food, fibre and fodder. Various anthropogenic activities leading to accelerated land degradation through salinization, flooding, water logging, erosion of water and nutrients, drought reduced agricultural productivity and nutritional security in the country. These problems can be overcome by optimum utilization of land adopting suitable management practices. For effective land management practices, the soils should be interpreted in forms of their land capability, suitability for irrigation and crop growth. This will not only help the farming community and extension specialists, but also to the administrators and policy makers for using soils for sustainable agricultural production.

1. INTRODUCTION

When the fruits and vegetables are ready for the intended purpose, these have to be harvested. What is meant by harvesting and how the produce is harvested, what are the harvesting methods, how these are packaged in what type of packages have been discussed in this chapter.

2. HARVESTING

Harvesting of produce at proper maturity is of paramount importance for maintaining quality during storage and marketing. When the produce is harvested immature or over-mature, it will affect the quality and storage life adversely. After the proper maturity stage has reached, the produce needs to be harvested for various markets. While harvesting, it must however, be kept in mind that all horticultural produce (with the exception of some dry fruits/nuts) is very delicate and mishandling at harvesting may lead to mechanical injury, compression injury that is irretrievable. The injury on fruits/vegetables enhances ethylene production, moisture loss and serves as an entry point for a wide range of pathogens, hence causing quick loss in quality and storability of produce. The injury caused to the produce during harvesting not only spoils the commodity but also makes it unfit for long-term storage or long-distance transportation. Proper training to the labour engaged in harvesting on what to harvest, and how to harvest and the use of proper harvesting tools can reduce considerably the postharvest losses.

1. INTRODUCTION

Since vedic times, importance of fermented milk and its products was known but the major attention to probiotic and its health related benefits was gained after Eli Metchnikoff’s publication entitled “The prolongation of life” in 1908. Due to the awareness of the role of nutrition in health and well-being, improved knowledge of diet-related diseases, consumer demand for probiotic and prebiotic products has been increased in recent years. The link between diet and health is flourishing the market for health-embracing population and opens an opportunity for Food and Dairy Industries meet the demand of this market. Probiotics, constituting live micro organisms, have been incorporated into drinks, food products, supplements (tablets, capsules and freeze–dried preparations) and prebiotic products. Milk, milk based products, fruits and vegetables are rich in functional food components such as minerals, vitamins, dietary fibers, and antioxidants (phytochemicals). Application of probiotic bacteria in such products further enhances the nutritional value of the food product. Probiotic juices produced from fruits and vegetables have also been in consideration in recent years. The food market is being getting captured by pro- and prebiotic food products day-by-day. Even the agro-industrial by-products such as whey, wheat straw, rice straw, sugarcane bagasse, etc. are being explored for the economical and cost effective production of prebiotic molecules. Thus, this chapter gives a comprehensive overview of pro- and prebiotics and their market potential.

1. INTRODUCTION

Stone fruits belonging to family Rosaceae (sub family-Prunoideae) include several important fruit crops like peach, plum, apricot, cherries, nectarines etc. The World production of these stone fruits is approximately 45.49 million tones; out of which 39.61 million tones stone fruits are grown in Asia and India contributes 6.67 million tones of stone fruits annually. Among all the stone fruits Peach, Plum and Apricot production in world is 24.98, 12.05 and 4.11 million tones, respectively whereas India alone produces 287778, 261903 and 17862 metric tones of peach, plum and apricot, respectively (Table 1). These stone fruits are grown extensively in USA, Spain, France, Italy, Turkey, Morocco, Iran, Africa and Australia. In India, these are grown in J&K, Himachal Pradesh sub-mountainous tracts of Punjab, Uttarakhand, North East States and to the limited extent in the Nilgiris hills. Primarily, these stone fruits are used for table purposes or processed to prepare various types of value added products like jam, jelly, marmalades, preserves, baby foods, nectar, juices, squashes, concentrates, ready-to-serve beverages, wines and also processed into dried products.

1. INTRODUCTION

Food processing involves the use of wide range of unit operations and technologies to transform the raw, bulky and perishable food into more shelf-stable, palatable and marketable food products. Food processing is one of the most effective solution to reduce the wastages, improves the quality and safety aspects of food products, increase the food availability and marketability. Fruits and vegetables are considered as an integral part of any dietary system as these are rich sources of vitamins, minerals and dietary fibres. India is the second largest producer of fruits and vegetables after Brazil and China which contributes 10 % of world fruit production and 14 % of world vegetable production. Fruits and vegetables are more prone to spoilage as compared to cereals due to their nature and composition. The spoilage can be occurr at the time of harvesting, handling transportation, storage, marketing and processing that results in lot of wastage in the form of seeds, pulps, peels etc. Efficient management of these wastes can help in preserving vital nutrients of fruits and vegetables, and bringing down the cost of production of processed foods, besides minimizing pollution hazards. In India, processing of fruits and vegetables is extremely low as compared to the developed countries.

Biotechnology can help in the bio-processing of fruits and vegetables for the production of novel products having better sensory and nutritional qualities, improved shelf life. Bio-processes involve the use of different micro-organisms and enzymes along with modern biotechnological techniques like genetic engineering.

In any organism and biomolecules (enzyme, proteins, etc.), most biological activities could be seen only within a narrow environmental conditions. Therefore in order to carry out a successful experiment, from cell culturing to DNA sequencing or assessing an enzyme’s activity, one has to pay utmost attention in calculating correct reaction components.

A solution is defined as a homogenous mixture of solute and solvent. In this case the amount solute is less as compared to the solvent. It is not always necessary that solvent is liquid and solute is solid. There are several examples where solute and solvents are found in other physical states such as gas or solids. For example, carbonated water CO₂ is solute and water is solvent; and smoke is solution of different smoke particles (solute) in air (solvent). The concentration of solution is described as amount of solute in a given volume of solvent. Several ways are there to express the concentration of a solution, such as molarity, normality, molality, and ppm. In this chapter we would discuss the general terms used in making solutions and a brief introduction about buffer solutions.

Nucleic acid extraction from clinical samples is the first step to be followed in molecular detection of cancer. Nucleic acids are the starting material for all downstream molecular diagnostic tools. Quality of test results largely depends upon the quality of starting material. Thus utmost importance should be given to the extraction protocols to isolate good quantity and good quality nucleic acids from patient samples.

Basic principle: The basic principle of nucleic acid extraction is to disrupt cell membrane and nuclear membrane to release and precipitate nucleic acid in the solution. Following precipitation,removal of other cellular contaminates such as protein, lipids, polysaccharides etc is performed to obtain a good quantity and quality of nucleic acid.

7.1 Basic concept

What is DNA sequencing?

The genome of any biological organism is a sequence of nucleotides arranged in a specific manner. The nucleotides are chemically a base which usually exists in 4 different forms; Purine – Adenine (A) and Guanine (G) and Pyramidine – Cytosine (C) and Thymine (T). These four nucleotides make up an entire sequence of Deoxyribose Nucleic Acid (DNA) which is encodes the information of any cell in the form of a gene. The genome, therefore, is the complete set of all genes that is required to build and maintain that organism. DNA sequencing is the process wherein the precise order of these nucleotides along the gene is detected and analysed which includes any method or technology that assists in determining the sequence.

3.1 Introduction

Genetics deals with genes and cytogenetics with chromosomes that harbour genes. On the other hand, plant breeding strives to upgrade the genotypes of crop plants. So, the plant breeding methods should be based on genetic principles. Dear students, you should have clear understanding of genetics in broad sense so that you can appreciate the applicability of breeding methods. As I have already pointed out that you have been taught the course ‘Principles of Genetics and Cytogenetics’ in the first semester, only a brief discussion is followed for your review and better understanding.

3.2 Character

When we call ‘character’ or ‘trait’ in genetics, we mean any morphological, anatomical, biochemical or behavioural feature of an organism. For instance, flower colour, blooming period, leaf size, size of guard cells in stomata, vitamin C content, disease resistance etc. A single gene or a number of genes may govern the development of a character and, often it is influenced by the environment. Characters may be qualitative or quantitative.

15.1 Introduction

Plant breeding aims at developing genetically improved crop cultivars with economic benefits for small-scale and commercial farmers. Population growth, dwindling agricultural land and global climate change present increasing risk to crop production. Consequently, plant breeding aims to constantly develop crop cultivars with improved yield and quality and tolerant to drought, diseases and pests. Use of genetically improved crop cultivars and better management practices are among the best strategies to increase food production and meet a projected doubling of food demand in the next 40 years. Both the public and private plant breeding sectors face several constraints, including a shortage of professional plant breeders and breeding technicians, limited budget, inadequate facilities and lack of access to information. Successful plant breeding requires adequate infrastructural investment, in addition to the actual breeding activities. The benefits of plant breeding research and development can only be realized on a long-term basis because of the inherent nature of the crops and the eminent breeding procedures involved. Plant breeding involves two main activities, i.e., pre-breeding/ germplasm enhancement and cultivar development per se. These interdependent activities are the controlling factors that determine the pace at which cultivars are released timeously and consistently to farmers. The two phases, in turn, depend upon various factors, e.g., breeding goals, genetics and agronomy of the crop, breeder’s long-term objectives, availability of testing facilities and national cultivar-registration requirements. Despite these factors, there are certain clear steps and breeding procedures found in any conventional breeding programme. These include choice of parents, making crosses among chosen parents, and selection from recombined parents followed by extensive field testing of the candidate cultivars. Maintenance, multiplication and distribution of the seed are the ultimate stages of a breeding programme. Systematically outlined conventional breeding procedures, timeframes and estimated breeding generations are essential to objectively consider the ultimate timescales required to release new and improved cultivars of all crops. The information may assist plant breeding- students, educators, researchers, project advisors, administrators and funding agencies. Dear students, in this chapter we outline the timeframes of conventional breeding procedures of clonally (also called vegetatively) propagated, self-fertilizing (also called self-pollinated) and cross-fertilizing (also called cross-pollinated) crops.

17.1 Introduction

Self-pollinated vegetable, spice and ornamental crops may be heterogeneous. It is exemplified by landrace cultivars. They may have originated from single plant selections but have been grown over a long period of time. Landrace cultivars are a mixture of genotypes, perhaps because of breeders’ lack of appreciation of selection techniques to produce a pure line, spontaneous mutations, chance hybridization, or a combination of factors. Natural selection in landraces has resulted in a cultivar that is well adapted to the local environment. Depending on amount of human selection, differences among genotypes in a landrace cultivar may be small and inconspicuous. On the other hand, a lack of human intervention may mean that differences among plants in a landrace cultivar will be conspicuous. After years of self-pollination, individual plants are homozygous. Selection of such individuals would result in a true-to-type reproduction of their phenotype within the limitations imposed by the environment.

22.1 Introduction

Mutations are sudden heritable changes in the genotype of an organism. De Vries (1900) for the first time used the term mutation (mutare in Latin means ‘to change’) for the appearance of new types in evening primrose (Oenothera) plant. In 1901 he put forth the idea of producing mutations artificially for use in crop improvement. Alberto Pirovano (1922) was first to use X-rays and ultraviolet rays for inducing mutations in plants, but his work remained unknown. So, Muller (1927) became the first known to induce mutation in Drosophila fly using X-rays. Though Stadler (1928) had started working simultaneously on barley and maize and induced mutations, he was late in reporting mutation due to longer life cycle of these plants compared to Drosophila. Mutation may be gene mutation (the result of change in the nuclear gene or plasma gene) or chromosomal mutation (change in chromosome number, structure or chromosomal aberrations of various types).

1. Introduction

Women empowerment is critical to the process of community development as well as for economic growth. Gender budgeting is recognized as a distinctive technique of women empowerment that directly upholds women development through allocation of budgetary fund. It aims at bringing gender equality through allocation of public funds and affirmative action for under-privileged sections. In fact, the term gender budgeting has been explained differently by various authors. A comprehensive definition states “gender budgeting as a dissection of the government funds to establish its gender differential impacts and to translate gender commitments into budgetary commitments” (Sharp, Rhonda, 1999). It can be viewed as a mainstream application of gender in the budgeting process. It ensures gender assessment of the budget, including reorganization of revenue and expenditure to incorporate gender perspective at all levels of the budget process. Gender budgeting therefore deals with gender specific formulation of laws, policies, plans, schemes and programs by allocation of resources; implementation and execution; monitoring, review and its impact assessment. It analyses the government budget from a gender perspective to assess how it addresses the needs of women in the areas of health, education, employment etc. It uses the budget as an entry point and apply the gender lens to the entire process of programme implementation.

Public budgets have different effects on women and men, and describe the unequal distribution of power in society in terms of economic disparities, differences in living conditions and ascribed social roles. Gender budgeting aims to visualize the gender impact of budgets and to transmute them into an instrument for increasing gender equality. Gender budgets basically includes all types of governments at the national, regional and local levels.

West Bengal

In West Bengal, mangroves are present in Sundarbans, the large deltaic complex of three major rivers, the Ganges, Brahmaputra and Meghna, and 62% of total area is shared by Bangladesh and 38% by India. The Sundarban Biosphere Reserve (SBR), at the confluence of the Bay of Bengal covering an area of 9,630 km², lies between 21°40′N and 22°40′N latitudes and 88°03′E and 89°07′E longitudes, spreading in districts of South and North 24-Parganas in West Bengal, India. The major portion of SBR is designated as Reserve Forest, covering nearly 4260 km² and the area under mangrove vegetation is 2112 km² (FSI 2019). Compared to 2017 assessment there has been a decrease of 2 km² area of mangroves. The mangroves and their associates in the SBR exhibit great generic and species diversity and it is abode to rare and highly endangered flora and fauna, as well as, the only mangrove-tiger (Royal Bengal Tiger - Panthera Tigris tigris) kingdom in the world. Recognizing importance and uniqueness, the United Nations Educational, Scientific and Cultural Organization (UNESCO) declared the Indian part of Sundarbans as a ‘World Heritage Site’ in 1987, and also designated the ‘Sundarban Biosphere Reserve’ under the UNESCO Man and the Biosphere (MAB) program in 2001. Recently, Sundarbans has been declared as a Ramasar Site, considering ecological significance. Totally 33 true mangrove species belonging to 21 genera and 13 families have been identified in Indian Sundarbans. Among the mangrove species listed, Rhizophora apiculata, Bruguiera parviflora, Ceriops decandra, Kandelia candel, Aglaia cucullata, Excoecaria indica, Xylocarpus moluccensis, Xylocarpus granatum, Heritiera fomes, Scyphiphora hydrophyllacea, Brownlowia tersa, Nypa fruticans, Acanthus volubilis, Dolichandrone spathacea and Phoenix paludosa are under serious threat in Sundarbans (Kathiresan 2008; Gopal and Chauhan 2006). Particularly Heritiera fomes (locally called Sundari, from which Sundarbans derives its name), Nypa fruticans and Phoenix paludosa are declining rapidly due to the reduction of freshwater input (Gopal and Chauhan 2006).

Threats

There are sixteen threat factors have been identified from Indian mangroves (Kathiresan 2010). However, habitat conversion for agriculture and aquaculture activities, environmental pollution by upstream anthropogenic activities, Climate change processes (e.g. sea level rise; increasing frequency of cylones, etc.) are the major threat factors for mangroves. Mangroves are able to cope up with short-term oscillations and long-term fluctuations of climatic conditions, but the consequences of global climate change, such as increased extreme events, will have unprecedented effects on biota and threaten the resilience and recovery potential of the ecosystems (Harris et al. 2018; Sippo et al. 2018). Despite conservation measures, the mangroves still experience an annual loss of 0.2-0.7% during 2000-2012 and they remain the most threatened ecosystem of the world (Hamilton and Casey 2016).

Basics of effective oral presentation : Planning , preparing (Introduction, Body and conclusion), Delivery, Body language and Handling anxiety-Strategies for giving oral presentation

Oral presentation means delivering an address to a public audience. It also refers to public speaking and/or speech-making. It is a brief discussion of a defined topic delivered to a public audience in order to impart knowledge or to stimulate discussion. The skill in oral presentation is equally as important as effective writing. Almost every oral presentation contains an introduction, main body and conclusion like a short paper. Though it is a formal speech in nature or vocal performance to an audience, it may occasionally require adequate planning and thorough preparation in using one’s voice, body language and visual aids such as slideshows to present and illustrate the points more effectively and to achieve the desired results.

Body languages such as eye contact, facial expression, posture and gesture plays a significant role in oral presentation process. The proper use of the voice and the ability to adjust it to suit the slightest differences of meaning are also very important in oral presentation. In addition to correct pronunciation, variation in pitch and cadence, free from speech mannerism, fluency in delivery are also very important in oral presentation.

Meaning-Steps for individual presentation; Group presentation-Meaning-Stages of group presentation; Impromptu presentation.

A Presentation is the process of presenting a topic to an audience. It is typically a demonstration, introduction, lecture, or speech meant to inform, persuade, inspire, motivate, or to build good will or to present a new idea or product.

Individual Presentations allow a person to completely control the thoughts, ideas, and methods of presenting without outside influence. Individual presentations allow someone to work at their own leisure and pace.

The practice of showing and explaining the content of a topic to an audience or learner is known as presentation. A presentation is a process of offering for consideration or display.

Presentations can also be categorized as expository or persuasive. They can also be impromptu, extemporaneous, written, or memorizes. But it’s more important to focus on their purpose. There are three basic purposes for giving presentations:

Intellectual Property: Intellectual property is an intangible creation of the human mind, usually expressed or translated into a tangible form that is assigned certain rights of property. It includes, inventions, trademarks, industrial design and geographical indications.

Intellectual Property Rights: Intellectual property rights (IPR) are the rights given to people over the creation of their minds. They usually give the creator an exclusive right over the use of his/her creations for a certain period of time. It includes, creations of the mind: inventions, literary and artistic works, and symbols, names, images, and designs used in commerce.

ABSTRACT

World is suffering from coronavirus infection since the end of 2019. Corona virus disease spraying rapidly throughout the world from the beginning of 2020, for that cause it is declared as pandemic by WHO in march 2020. As no proper remedy found for this particular new disease till the date it is become oblivious to maintain social distancing and lock down. Due to the situation each and every sector including the education system totally stopped from March 2020. But we have to maintain the flow of education. Many of the educational institution of India promoted e learning for their students. To avoid coronavirus infection social contact as well as to carry out classes in regular manner, it is become necessary to promote e learning everywhere. But in India the situation is different because Steel we are a poor country where a good number of people do not have a smart phone even. There are many challenges in promotion of e-Learning during this coronavirus pandemic situation in India. In present paper we are going to discuss about some challenges in promotion of e-learning due to coronavirus pandemic situation.

ABSTRACT

The advent and implementation of Information and Communication Technology (ICT) in library operations changed the overall information scenario. The format of libraries, information resources and user expectations are completely changing. Similarly, the role of librarian is continuously changing in the digital era. No library can fulfill the informational demands of the users; hence, resource sharing is required between the libraries. Consortiums are developed to enable the institutions to access the rich and scholarly resources at an affordable cost. The present paper discusses the basic concept of resource sharing, consortium types, need, advantages and disadvantages and its role in sharing information.

Keywords: ICT, Consortium, Library consortia, Resource sharing.

9.1. Fungi useful against plant disease pathogen

9.1.1. Trichoderma viride

Trichoderma viride (Fig. 231) fungus is used as a bio-fungicide. It is used for seed and soil treatment for suppression of various diseases caused by fungal pathogens. It is also a pathogen in its own right,causing green mould rot of onion.

The fungicidal activity makes T. viride useful as a biological control agent against plant pathogenic fungi. It has been shown to provide protection against pathogens like Rhizoctonia, Pythium and Armillaria.

It is found naturally in soil and is effective as a seed dressing bioinoculant in the control of seed and soil-borne diseases including Rhizoctonia solani, Macrophomina phaseolina and Fusarium species. When it is applied to the seed, it colonizes the seed surface and kills not only the pathogens present on the cuticle, but also provides protection against soil-borne pathogens.
