ICAR Frontline Extension Programmes

It was recognized by Indian Council of Agricultural Research (ICAR) in the early sixties that agriculture development requires interdisciplinary and multi institutional approach. The integrated functioning of agricultural research, education and extension was for the first time recognized as the cardinal principle of agricultural development system, and accordingly agricultural research, education and extension function were integrated in the ICAR institutes and State Agricultural Universities (SAU). ICAR established a Section of Extension Education at its headquarter in 1971, which was later renamed as Division of Agricultural Extension to promote the transfer the agricultural technologies through the ICAR-SAU system. The present position, as on 31.03.2020, of ICAR institutes, Central Agriculture Universities and SAUs are as follows:

Ice cream over the years has come to acquire an easy acceptance as a healthy, nutritious and hygienic food for the aged, sick, growing children and adults. Its popularity, as demonstrated on all types of occasions is growing fast and its potential appears to be unlimited.

Gone are the days when the word “Ice Cream” was synonymous with strawberry and vanilla flavours or the innocuous orange. Ice cream is available in many forms, flavours and packages. Today, there are exotic variations to titilate the palate, such as Jingle Bells, Goody goody Gum Drops, Champagne Snowballs, Mr. Frost, Tutty Fruity, Butter Scotch, etc, waiting to launch customers on a gastronomical voyage.

It is uncertain how long ice cream has been produced, however, the International Association of Ice cream Manufacturers (1966) traces the beginnings of ice cream and frozen desserts to iced drinks enjoyed by Alexander the Great in the fourth century B.C. down through the years Nero in the first century A. D., Marco Polo in the 13^th century through Italy and France to England in 1643-1649, and to America around 1700. From a very old writings it has been learnt that the Chinese liked a frozen product made by mixing fruit juices with snow, what we now call water ice. It is believed that ice cream evolved from iced beverages and water ices that were popular in the medieval period. This technique later spread to ancient Greece and Rome, where the wealthy, were partial to frozen desserts.

After disappearing for several centuries, ice creams in various forms reappeared in Italy in the Middle Ages, most probably as a result of Marco Polo returning to Italy in 1295 after a 16-17 year stay in China, where he had learnt to appreciate a frozen dessert based on milk. There is no gainsaying the fact that the true origin of ice cream cannot be proclaimed with a fair measure of certainty but, all the same, the Italians claim that Benaroo Bountalenti, a resident of Tuscany, invented ice cream in the early 1300s. From Italy ice cream spread over Europe during the 17^th century, and for long remained a luxury product for the royal courts. Italian ice cream was very popular in London around 1870.

18.1 Introduction
Ice cream is produced by freezing a pasteurised mixture that is derived from milk or milk products, with or without nutritive sweeteners and other approved non-dairy constituents, in accordance with FSSAI standards. Except for softserve ice cream, which may remain malleable, this product must freeze solid and may contain air. Ice cream is manufactured using bovine or buffalo milk, cream, or milk products. It may also contain cane sugar, eggs, fruits, fruit juices, preserved fruits, nuts, chocolate, edible flavours, and approved colours. Up to 0.5% by weight of stabilisers and emulsifiers are permissible. The mélange must be heated to the appropriate temperature prior to freezing. A minimum of 10% milk fat, 3.5% protein, and 36% total solids must be present in the product. However, the proportion of milk fat may be reduced to no less than 8% by weight when any of the aforementioned preparations contains fruits, almonds, or both. A declaration to that effect must be included on the label, and starch may be added to a maximum extent of 5%.
18.2 Classification
Some of the frozen desserts can be classified as follows.
1. Plain: Plain ice cream has minimal coloring and flavoring, such as vanilla and coffee.
2. Chocolate: Chocolate ice cream is flavored with cocoa or chocolate
3. Fruit: Fruit ice cream contains fruits like strawberry, apricot, pineapple, mango, or banana, which may be fresh, frozen, canned, or preserved.
4. Nut: Nut ice cream includes nuts like almonds, pistachios, walnuts, or cashews, with optional additional flavoring or coloring.

1. Pharmaceutical Quality System

1.1 Introduction

This document establishes a new ICH tripartite guideline describing a model for an effective quality management system for the pharmaceutical industry, referredto as the Pharmaceutical Quality System. Throughout this guideline, the term “pharmaceutical quality system” refers to the ICH Q10 model.

ICH Q10 describes one comprehensive model for an effective pharmaceutical quality system that is based on International Standards Organisation (ISO) quality concepts, includes applicable Good Manufacturing Practice (GMP) regulations and complements ICH Q8 “Pharmaceutical Development” and ICH Q9 “Quality Risk Management”. ICH Q10 is a model for a pharmaceutical quality system that can be implemented throughout the different stages of a product lifecycle. Much of the content of ICH Q10 applicable to manufacturing sites is currently specified by regional GMP requirements. ICH Q10 is not intended to create any new expectations beyond current regulatory requirements. Consequently, the content ofICH Q10 that is additional to current regional GMP requirements is optional.

ICH Q10 demonstrates industry and regulatory authorities’ support of an effective pharmaceutical quality system to enhance the quality and availability of medicines around the world in the interest of public health. Implementation of ICH Q10 throughout the product lifecycle should facilitate innovation and continual improvement and strengthen the link between pharmaceutical development and manufacturing activities.

Introduction

Minerals are present in all body tissues and fluids to carry out the physicochemical processes of life; both in animals and human. It is broadly classified into two categories: (1) macro and (ii) micro or trace elements. The macro elements include calcium, phosphorus, potassium, magnesium, sulfur, sodium and chloride, while elements such as iron, copper, cobalt, iodine, zinc, manganese, molybdenum, selenium and chromium come under micro elements. Animals need large amounts of calcium for construction and maintenance of bone and normal function of nerves and muscles. Phosphorus is a vital constituent of adenosine triphosphate (ATP) and nucleic acid and is also essential for acid-base balance, bone and tooth formation. Iron is an important component of the cytochromes for carrying out cellular respiration in addition to its vital role in red blood cells. Magnesium, copper, selenium, zinc, iron, manganese and molybdenum are important co-factors found in the structure of certain enzymes and are indispensable in numerous biochemical pathways. Animals need iodine to make thyroid hormones. Sodium, potassium and chlorine are important in the maintenance of osmotic balance between cells and the interstitial fluid. Excessive intake of some minerals can upset homeostatic balance and cause toxic side effects.

Introduction

ICT may be defined as technologies that facilitate communication and the processing and transmission of information by electronic means. ICT is an acronym that stands for Information Communications Technology and refers to technologies that facilitate communication and the processing of information by electronic means and includes everything from radio and television to telephones (fixed and mobile), computers and the internet. Information and communication has become an increasingly powerful tool for improving the delivery of basic services and enhancing local development opportunities. Recent years have seen increases in the use of ICT in almost all spheres of rural life. Especially, the rural communities require information among others on supply of inputs, innovations, improved technologies, credit, market prices and competitors. Since the concepts, methods and applications involved in ICT are constantly evolving on an almost daily basis. It’s difficult to keep up with the changes - they happen so fast.

Introduction

E-publishing and information accessing have become easy and convenient mainly because of Internet and the World Wide Web technologies. Most digital libraries were developed in the past by taking up projects based on specific disciplines and then developed into full-fledged digital libraries. The inter-networking communication links, low cost storage solutions, powerful desktops, workstations, servers and multimedia hardware and software technologies are now available for initiating the Digital Library projects in India. Development in ICT (Information Communication technology) have brought about the merger of the computing, information, Communication, entertainment, mass media industries thereby providing a means of exchanging information in the digital format used by computers.

All agriculture universities have three main Directorates – Education, Research and Extension. Of the three, I have often observed that Extension Department comes in for maximum criticism. ‘Loose links’and ‘need to do much more in transfer of knowledge and technology’ are frequently emphasized at various levels – especially in meetings with farmers groups.

This is understandable – as it is said that less than 10% - often less than 6%, of lab scale knowledge and development reach the farmers fields in developing countries and even in many ‘developed’ counties. The situation is much more challenging when we consider a large population of small and marginal farmers – who as we saw can play extremely important role in eco-agriculture. A large percent of such farmers – women and men are practicing eco friendlyagriculture without realizing it. Their ‘ignorance’ can be converted in to advantage and new opportunity. The age old extension practice of reaching farmers through meetings, visit , seminars, camps, demonstrations all have limitations and need to be ‘scaled up’. New developments in information and communication Technology offer a great opportunity for a big jump in reaching the unreached. Again to alarge population of ‘Green Revolution’ – there is a new hope and opportunity.

ICT in Agriculture
The potential for using ICT in agriculture can be divided broadly under two heads (1) as a tool for direct contribution to agricultural productivity and (2) as an empowering tool for the farmer to take and quality decisions. There have been several excellent examples of practical use of ICT in Agriculture and expectations are rising such that a major transformation

The term Information and Communication Technologies (ICT) encompasses a broad spectrum of electronic tools that converge to facilitate information processing, communication, transmission, and display. Scholars like Michiels and Van Crowder (2001) define ICTs as a constellation of electronic technologies capable of transforming organizations and reshaping social relations. In the context of agriculture, the integration of ICT holds significant promise, offering a myriad of advantages ranging from accelerating agricultural growth to empowering marginalized farming communities. This review examines the need, catalytic role, advantages, scope, and limitations of ICT in agricultural extension, elucidating its potential and challenges in promoting sustainable rural development.

Need for ICT in Agriculture Extension

1. Accelerating Agricultural Growth: ICTs play a pivotal role in catalyzing agricultural development by providing timely access to critical information, knowledge, and resources.

2. Expanding Knowledge Resources: ICTs serve as repositories of agricultural knowledge, enabling extension workers and farmers to access comprehensive information on best practices, innovations, and market trends.

3. Facilitating Information Services: ICTs enhance the dissemination of agricultural information and advisory services, enabling farmers to make informed decisions on crop management, pest control, and market opportunities.

INTRODUCTION

Information is power in the present age of rapid technological innovations; since information technology (IT) empowers people. IT emerged as the major driver of growth in all walks of life during last quarter of 20^th century and is currently in a steady growth trajectory. It encompasses almost all human endeavors including agriculture. IT can facilitate agriculture in two broad ways; (i) as a tool for direct contribution to agricultural productivity and (ii) as an indirect tool for empowering farmers to take informed and quality decisions which will have positive impact on the way agriculture and allied activities are conducted. Precision farming extensively uses IT to make direct contribution to agricultural productivity. The indirect benefits of IT in empowering Indian farmer are significant and remains to be exploited. The emerging scenario of a deregulated agriculture under WTO has brought about a greater ‘need’ and urgency to make IT an integral part of decision making by agriculture sector. The changing environment faced by Indian farmers makes information not merely useful, but necessary to remain competitive. The farmer urgently requires timely and reliable sources of information inputs for taking decisions. At present, the farmer depends on trickling down of decision inputs from conventional sources, which are slow and unreliable. Besides, the personnel who work for the welfare of Indian farmers, such as extension workers, do not have access to latest information, which hinders their ability to serve the farming community effectively. IT will constitute the primary resource in agri-clinics, agri-business centers, kisan call centers, agri-nukkads, etc. that have been launched by Government of India and other organizations to ensure inclusive growth. Potato is an input-intensive crop and IT will have a special role in making its cultivation more productive and profitable.

ABSTRACT

The Cellular technology (mobile phone) is becoming popular day by day with companies up with low price handsets and nearly one-fourth of the India’s population possess a mobile phone even in the rural areas. The Indian government has set a target of 500 million users by 2010; half of this, 250 million, has reached till 2007 (IANS). Keeping in view the scenario, messaging agricultural information through computers to the end users on mobile phone is a means, which will go a long way for the farmers to receive timely information. There are different media platforms through which farmer’s access information in India. This includes radios, television, print, person to person and so many others. However, with the rapid growth in technology, there is a strong belief that there is a need to extend the mobile phones’ use to agriculture sector.

1. Introduction

Democratisation of information makes it possible for ideas, opinions, knowledge and services to be accessible to everyone, anywhere, anytime. In this era of ‘knowledge sharing’, making access to the required information and knowledge is the key to innovation and empowerment of farming community. Rapid technological developments over the years, particularly internet and mobile, have made it possible to provide array of services on a single platform due to convergence. It is a unique opportunity to leverage upon the available ICT infrastructures and deliver the knowledge based services effectively to people. There are number of ICT initiatives being attempted in the field of Agriculture and other sectors. Some of the successful models (web-based and mobile based) have shown way for the future of e-extension in India.

ABSTRACT

As population explosion continues and the shortage of extension personnel becomes acute, the wisest proposition is to utilize the latest information and communication technology (ICT) to make information available to the common man. The ICT  tools with their recent advancements have become easily available in various forms such a mobile telephone, PDA, WLL phones, FM radio, community radio, television, wireless internet services, webcams, video conferencing facilities etc. Extension agencies need to harness the ICT tools usefully and improve the quality of extension services.

INTRODUCTION

Krishi Vigyan Kendras (KVKs) also known as Agricultural Science Centres are the integral component of the National Agricultural Research System, which aims for development and promotion of location specific technology modules in agriculture and its allied enterprises, through Technology Assessment, Refinement and Demonstrations. At present there are 585 KVKs in the country grouped under eight zones and 77 in Zone VIII comprising of Karnataka, Kerala, Tamil Nadu, Goa, Puducherry and Lakshdweep.

The major mandate of the KVKs includes Technology Assessment and Refinement through on Farm testing, popularization of technologies through Frontline Demonstrations to prove their production potentials in the farmers’ field. Conducting skill oriented training programmes to farmers and farm women, rural youths and extension personnel mostly focussing the technologies assessed/refined or demonstrated, conducting vocational training programmes for rural youth, popularization of technologies through various extension programmes so as to reach the masses, production and supply of good quality seeds, planting materials and other bio-products to the farming community.

ABSTRACT

Information and Communication Technology (ICT) is the driving force for the fundamental economic and social revolution. It accelerates globalization, makes access to knowledge and information much easier for the people in respect of creation of technologies, diffusion of old innovation and diffusion of human skills for rural prosperity. The National Conference on Informatics for Sustainable Agriculture Development (ISDA) organized by the Ministry of Agriculture and National Informatics Centre (NIC), in May 1995, has given much needed “roadmap” to usher in “ICT led agriculture development” in the country.

Introduction

In today’s world, the use of Information and Communication Technology (ICT) have become more common and part and part of human life. It plays many roles for a country’s overall growth and economic development. Among all developing countries, the presence of ICT is greatly felt in India. People here use ICT devices mainly to access and share data information available around the world from any part of the country and at any time with just one click. In the last fifteen years, India’s economic growth has been remarkable in trade and commerce, communication technologies, education, transportation, agriculture and administration mainly due to development of advanced software and service based applications. India stands as a role model for many other countries in framing ICT based policies and implementing independent strategies for global contracts (Carmel 2003; Heeks and Nicholson 2004). Since, its significance is highly realised by the Government, bureaucrats and policy makers’ efforts are now being carried out to utilize ICT tools for improving the lives of the Indian rural maases and people below poverty line.

The intersection of Information and Communication Technologies (ICT) with agriculture has sparked a transformative revolution in the farming landscape. ICT projects in agriculture represent a paradigm shift, leveraging technological advancements to optimize farming practices, enhance productivity and ensure sustainable food production. From precision farming and data-driven decision-making to innovative tools and connectivity solutions, these projects harness the power of digital innovation to address challenges and drive efficiency across the agricultural sector. In this era where technology has become a cornerstone of progress, ICT projects stand as beacons of hope, ushering in a new era of smarter, more resilient and eco-conscious agriculture. The initiatives of ICT projects in agriculture and allied sectors

Information and communication technology (ICT) is the combination of hardware, software and the means of production that enables the collection, exchange, processing and management of information and knowledge. It includes social media, portals, websites, kisan call centers and expert systems etc.,

Need of ICT in agriculture and rural development

• For increasing the productivity and efficiency in agriculture
• Globalization, Modernization, Challenges and Opportunities across the world for Sharing of knowledge.
• Public Expenditure and gaps in extension could be reduced
• For effective utilization of available platforms
• Penetration of smartphones even in villages and the transfer of information

ABSTRACT

ICT innovations are bringing new information services to rural areas on which, farmers, as users, will have much greater control than ever over current information channels. A greater opportunity to access the services of ICT innovations is crucial requirement for the sustainable development of the farming system, which is the demand of the time. ICT when applied to the rural and agricultural conditions can improve the linkages between research and farmer sub-systems. The variety of new ICT tools for agriculture is impressive, but the tools need to be placed in an overall context of agricultural information and service needs. By looking at the critical information needs of agriculture and farming communities, the focus should be on applicable and relevant ICT tools for the specific purpose to serve the rural community without compromising with their individual applications towards understanding of their overall role in promoting productive, equitable, and sustainable agriculture. Extension workers well equipped with the ICT can prove more efficient in gathering, storage, retrieving, adaptation and dissemination of broad range of information needed by farmers, thus transforming them from extension workers into knowledge workers. Emergence of such knowledge workers will result in the realisation of the much talked about bottom-up, demand driven technology generation, assessment, refinement and transfer.

ABSTRACT

This study addresses the many ICT-based services provided to readers as well as access to E-resources by Mahatma Gandhi Kashi Vidyapith, University users. It raises awareness of technology in libraries and why it is important to comprehend the usage of ICT in libraries in order to provide better library services and information to users. Essentially, the article describes several technologies and their applications in library operations. The study has discussed how library services are spurred by the use of technology such as OPAC, E-ShodhSindhu, E- books and E-journals, and so on. The current study examines several library activities that make use of ICTs. The goal of this paper is to demonstrate the use of various ICTs and E-resources by user of the university for rapid and easy information retrieval.

Like many other developing countries, agriculture is the primary occupation of the rural people of North East India. They depend on farming but because of the nature of practices followed, it hardly goes beyond subsistence and so agricultural extension is an important thing in their lives. But in this particular part of the country basically because of the topography which makes it difficult to reach the clusters of villages deep in the hills, forests and valleys, it becomes more and more important to use technologies that reach them like mobile phones, TV and radio. Agricultural information is not something that is needed 24X7 round the year but require on the critical times of the year like before sowing seasons advisories, forecasting diseases and pests when the crop is standing in the field and during harvesting.

ABSTRACT
 
The term rural development also represents improvement in quality of life of rural people in villages. As per Chambers (1983) “Rural Development is a strategy to enable a specific group of people, poor rural women and men, to gain for themselves and their children more of what they want and need.”  ICT is an integral part of development strategies of both developing and developed countries. It has great potential to bring in the desired social transformations by enhancing access to people, services, information and other technologies (Dutton et al., 2004). ICT applications can enhance poor people’s opportunities by improving their access to markets, health and education. Furthermore, ICT can empower the poor by expanding the use of government services and reduce risks by widening access to micro finance (Cecchini and Scott, 2003). The uses of ICT for development are actively promoted for economic development, job-creation, rural development and poverty-alleviation. The term ‘ICTs’ can be interpreted as including a wide range of media, ‘new ICTs’ is used to denote “the use of computers and communication systems between computers” (CTA 1999:4).

Abstract

ICT is contributing in every sphere of human society and agriculture cannot be an exception. It can bring revolutionary changes in farmers’ life by improving accessibility to information and knowledge. Farmers certainly feel empowered and with confidence can opt for innovative approaches in business farming. Nearly 70 percent of the bottom fifth of the population in developing countries own a mobile phone. The number of internet users has more than tripled in a decade, from 1 billion in 2005 to an estimated 3.2 billion at the end of 2015. Thus, ICTs provide faster and newer ways of delivering and accessing information to many and are potential tools for poverty alleviation, health, education, judiciary, agricultural marketing and sustainable development. As per an ICAR report 80 per cent of the technologies generated by the researchers in agricultural sector are either not transferred to the ultimate users or they do not find applicability in the farmer’s field. Out of the remaining 20 per cent of the technologies, around 50 per cent do not impress the farmers due to mainly its ineffective technology transfer that range from language to effective demonstration using the available tools. Information and communication technology revolution is the latest milestone in Indian agriculture that can usher an era of knowledge flow from institution to farmers field in much systematic and organized way and eliminate hurdles in technology transfer and adoption. From the perspective of agricultural knowledge and information systems (AKIS), ICTs can be seen as useful in improving linkages between the research, extension and the market sub systems. Real-time information and customized knowledge provided by ‘eChoupal’ enhance the ability of farmers to take decisions and align their farm output with market demand and secure quality and productivity. The eKrishi project, Market driven Agricultural Initiative through IT enabled Agri-business Centres in Kerala, addresses the existing gap in agriculture information flow and transaction management. The touch screen kiosk with information on cattle health was tried and tested under a United Kingdom Department of International Development (DFID) – Animal Health Program (AHP) supported project on dissemination of animal health knowledge for development of landless dairy cattle owners in the peri-urban regions of Pondicherry. Being a global resource, and with billions of users, the Internet requires some degree of international cooperation on technical matters as well as on standards and norms that can ensure that it remains a global public good, facilitating information flows and contributing towards sustainable development.

A cell culture laboratory should allow the sterile handling of cultured cells with no or minimum level of contamination. The growth of bacteria and fungi is very high and no level of contamination can be allowed in animal cell culture. However, it is impractical to design a laboratory free from potentially contaminated microorganism. Further, it is possible to establish a laboratory with minimal risk of contamination. Several points should be taken into consideration while designing a new cell culture laboratory.

Abstract

Survey conducted in different Lilium growing areas of Himachal Pradesh revealed the incidence of virus diseases between 15 and 95 per cent in different localities. Mild mottling, curling and necrosis of leaves, deformation and virescence of floral bulbs and flowers and reduction in bulb size were the most prominent symptoms observed. The virus isolate was transmissible through sap, bulb and aphid vectors and had a narrow host range. Electron microscopic studies revealed the presence of filamentous flexuous virus particles measuring 640×17-18nm in size.

Introduction

Mycorrhizal fungi are ubiquitous in soils throughout the world and form symbiotic relationships with the roots of most terrestrial plants. The infection of roots of most flowering plants by symbiotic fungi and the transformation of such roots into unique morphological structures are called Mycorrhiza. Over the years it has been convincingly demonstrated that inoculation of agricultural crop plants and forest trees with mycorrhizal fungi can significantly stimulate their growth and development. Such probiotic effects are more pronounced in nutritionally poor soils which occur in very large areas of the arid and semiarid tropics.

Mycorrhiza are classified into three different classes

16.1 Process of Ripening of Worms
Closer to the end of the fifth stage, the silkworm stops ingesting and turns into the so-called mature larva and starts spinning the cocoon. Properly reared worms, when ripe, will attempt to spin true cocoons even below incorrect conditions. However, it needs to be remembered that the worm spinning the cocoon is to defend itself from outside disturbances and enemies all through the maximum crucial period of its metamorphosis. The rearer can get the reward for his labour most effective, if he cooperates by making the situations such that, through spinning a commercially good cocoon it also most correctly protects itself. This cooperation is composed in imparting the ripe silkworm with appropriate mountages to facilitate its spinning of suitable cocoons. The eating duration throughout the fifth instar may close for 5 to 7 days in the case of multivoltine and bivoltine races in the tropical regions and 7 to 9 days in the case of bivoltine and univoltine races in sub-tropical areas. The mature worm is effectively distinguishable by its translucent colour. The frame also shrinks with duration; there is also a constriction seen on the 4th and 5th segments. The worm loses appetite and begins to look approximately as although on the lookout for a appropriate area to which to attach itself. Generally, the ripening worms circulate in the direction of the periphery of the rearing trays in search of anchorage to begin spinning of cocoons. This is the time for selecting the ripe worms and putting them on mountages. This process is known as ‘mounting’. It has to be remembered that all the worms in a tray do not ripen simultaneously. It commonly happens that by the time all the worms in a tray are ripe, a number of the early worms can be over-ripe. They could have misplaced a quantity of silk by the point they are picked up, and they are furthermore in a hurry to spin their cocoons that they continue to do it anyways, without ready to select a right location, and as a consequence produce irregularly formed and flattened or sticky cocoons causing loss to the rearer.

This practical assignment is conceptualized in a way that students will gain a deeper understanding of the rural situation and can prioritize the rural needs which will eventually help in achieving overall development of the rural people.

PURPOSE

IDENTIFICATION OF ANIMALS

It has been in practice since long, not recent item in livestock farming. In earlier day’s in Egyptian era, people used to mark the animal to identify their animals. But in recent days, due to development in bio-medical science where usage of animal has increased within turn has become necessary to establish a suitable identification method for various species of animal. There are many methods available to identified animal, however the methods employed should be simple, economical and easy to identify animal and should be harmless to animal, quickly applicable and should be suitable to experiment conducted.

7.1 Introduction
The three factors used to categorise silkworm races are: (1) origin, (2) voltinism and (3) moulting. In addition, they are categorised according to their shape and colour. For more than 2,000 years, people have tamed and raised the silkworm Bombyx mori. It is a monophagous insect that exclusively consumes the leaves of mulberries. As a result, mulberry silk is typically meant when the word “silk” is used.
7.2 Classification Based on the Place of Origin
(a) Indian Races: Native to South East Asia and India; these races are indigenous. They have a longer larval stage and can withstand high humidity and temperatures. The larvae and cocoon are modest in size. The cocoon is often spindle-shaped and coloured in shades of green, yellow, or golden yellow. With a lower shell percentage, the cocoon shell is thin and most of them are multivoltine.
(b) Japanese Races: Japan’s indigenous races comprise this group. The larvae are strong. The cocoon resembles a peanut. The majority of cocoons are white, while some are yellow in hue. There are more double cocoons in the ratio. The silk strand is thick and short and of poor quality and are bivoltine or univoltine.

 To help the students develop their skill in identifying the entrepreneurial traits one can have within him/her.

Identification / familiarization of various feed ingredients: As per National Research Council (N. R. C.), there are 8 main groups of feedstuffs. (1) Dry forages and roughages; All forage and roughage cut and cured are included in this category. These are bulky feeds with low digestibility. Crude fibre is more than 18 % and Total digestible is less than 60 % because of high cell wall contents. For example: dry grass (hay), wheat straw, paddy straw, oat straw, stovers (aerial part without ears), husk (maize) or aerial part without heads (sorghum), hulls and shells. (2) Pasture range plants, tree leaves and forages; Roughage either harvested or without harvesting (fresh) are included in this group. For example: pasture grass, range plants, tree leaves, green forages (legume and non – legume). (3) Silage; only ensiled forages are included. For example: legume non – legume silages. (4) Energy or basal feeds; Feeds are of low protein content, having crude protein less than 20 %, crude fibre less than 18 % and Total digestible nutrients more than 60 %. For example: cereal grains, milk by – products, fruits, nuts, roots etcetera; (5) Protein supplements; Feeds are of high protein , more than 20 %, crude fibre less than 18 % and Total digestible nutrients more than 60 %. For example: animal, marine, avian, and plant products. Meat meal, fish meal, oil seeds, and their cakes etcetera; (6) Mineral supplements; These are natural or pure elements. For example: composite mineral mixture or specific mineral supplements; (7) Vitaminsupplements; These are natural or pu e forms. For example: composite vitamin  pre–mix or specific vitamin supplements; (8) Feed additives; these are for improving efficiency of utilization of feeds. Number of examples have been cited elsewhere in this book [theoretical part above].

1. Mango

Varieties released from I.A.R.I., New Delhi

Malliaka: (Neelum x Dashehari)

This variety was released in 1971. Tree moderate, semi-vigorous to vigorous, moderate spreading, bearing moderately and regular. Fruit large, ovate-oblong; beak slight, sinus absent, peel thick, apricot yellow; flesh firm, fibreless. Fruit quality superb with excellent sugar acid blend., TSS (24-20° Brix), good keeping quality (15 days). It is suitable for table and canning purposes. Maturity during 3^rd – 4^th week of July.

8.1. Malformation

8.1.1. Fusarium

The classical example of Fusarium infection is Fusarium moniliforme which induces malformation in inflorescence, causing mango malformation disease.

The fungal mycelial morphology may vary significantly on different media, and the descriptions here are based upon growth on potato flakes agar (PFA) at 25° C with on and off fluorescent light cycles of approximately 12 h each. The mycelial colony has rapid growth.

5.1. Gummosis

5.1.1. Phytophthora\

Phytophtora citrophthora, Phytophtora nicotianae, Phytophtora syringae are the phytophthora species associated with citrus gummosis; while Phytophtora pistaciae sp. nov. and Phytophtora melonis are the principal causes of pistachio gummosis.

6.1. Leaf Spot, Blight, and Blast

Leaf spots are irregular or round blemishes found on either side or both sides of the leaves. A typical spot is “zonal,” meaning it has a definite edge and a darker border. When lots of spots are present, they can grow together to cover the larger areas of the leaves. Different fungi are responsible for the leaf spots and sometimes a particular fungus causes a peculiar type of leaf spot and includes the fungi.

9.1. Fruit Spot and Blisters

9.1.1. Colletotrichum

The pathogen forms papery or watery brownish areas at the site of infection, with a large number of acervuli on the infected parts. In the acervulus, the conidiophores are slightly curved, short, and club-shaped. The conidia are hyaline and falcate, borne singly on the conidiophores. Numerous black colored and thick-walled setae are also produced in the acervulus. In culture, most isolates produce cottony, fluffy, or suppressed colonies (Fig. 9.1).

10.1. Black Tip

The black tip of grain infection is mostly observed on the wheat grains.

The fungal pathogen involved in causing the black tip of grain includes the species of the fungal genus Alternaria and Helminthosporium.

10.1.1. Alternaria

The genus stands distinct from other genera by its transversely and longitudinally septate (muriform) conidia. The conidia are usually formed in chains. These are dark brown, typically obclavate with a distinct oval body and beak.

4.1. Damping Off

4.1.1. Pythium

Pythium has filamentous (thread-like), hyaline, and coenocytic (non-septate) mycelial growth. The asexual or vegetative stage of Pythium produces sporangia (that germinate directly to produce a hypha or indirectly to give rise to a vesicle outside the sporangium, within which zoospores are formed) and sometimes hyphal swellings (spherical sporangia-like structures that do not give rise to zoospores).
