Abstract

Studies were conducted to investigate the effect of growing media and fertilizers on growth and flowering of rose cultivar ‘First Red’ under naturally ventilated polyhouse. During first flush, it was observed that growing medium containing soil, FYM, sawdust (2:1:1) gave maximum flower yield (5.58 cut stems) per square meter per month when fertilized with water soluble fertilizers (N-150 ppm and K-200 ppm) whereas, maximum number of ‘A’ and ‘C’ grade cut stems were recorded from plants grown in soil: FYM: sand which were fed with straight fertilizers (N-150 ppm and K-200 ppm).

Abstract

The experiment was carried out to study the effect of  BA and GA3 on in-vitro raised plants of African violets. The studies revealed that BA 150 ppm spray increased the number of leaves and duration of flowering, whereas, GA3100 ppm increased leaf area, plant spread and resulted in earliest flowering. Number of flowers was maximum in GA3 100 ppm treated plants and was at par with BA 150 ppm. Maximum pot presentability (82.85 days) was found with BA 150ppm which was at par with GA3 100 and 50 ppm treated plants.

Abstract

Himachal Pradesh is endowed with varied type of climate providing conditions to grow temperate and sub  tropical fruits. Persimmon (Diospyros kaki) appears to be readily adapted to wide range of climatic conditions and offer a good potential for diversification of fruit culture. Though it was introduced in Himachal Pradesh in early nineties by the European missionaries but it could not be established as commercial fruit crop. Persimmon cultivation suffers from lack of organized plantings, inadequate vegetatively propagated plant material, non-availability of suitable cultivars and standardization of various orchard management practices. Besides, problems of poor fruit set, heavy fruit drop, astringent nature and lack of sufficient knowledge regarding fruit maturity and marketing mired its cultivation. The efforts made in recent years to overcome the problems the fruit seems to be on the thresh hold of popularity and with diversification in the fruit culture this fruit has great future.

Abstract

Powdery mildew infected leaves of apple hyperparasitized by Ampelomyces quisqualis were collected from field and examined for the presence of the dark brown pycnidia of  hyperparasite. The hyperparasite was isolated on potato dextrose agar medium by standard isolation technique. The morphological characters of the hyperparasite such as size and shape of pycnidia and pycnidiospores were studied. Six systemic fungicides were evaluated for their compatibility with A. quisqualis under in vitro conditions. Dinocap was least inhibitory giving 65.56 per cent growth inhibition of A. quisqualis followed by mancozeb (66.67%). Effect of these fungicides was also seen on conidial germination and germ tube length of A. quisqualis. Maximum conidial germination and germ tube length was observed in mancozeb followed by benomyl and dinocap.

Abstract

Amongst various soil-borne diseases of apple, white root rot (Dematophora necatrix) causes severe losses both in nursery as well as in grown up orchards and is a limiting factor in raising healthy nursery of apple. Seedlings are killed within a short period depending upon the age of the host and environmental factors. The present investigations were, therefore, undertaken to study the population dynamics of VAM fungi in rhizosphere soil  of apple plant alone and in combination with green amendments and its role in disease suppression. The study revealed that there was variation in population dynamics of VAM fungi alone and in combination with green amendments. It was observed that apple seedlings grown in VAM inoculated fungi (Glomus sp. and Glomus heterosporum) and green amended   soils had more VAM population and colonization in roots than non-amended (minus crop residue) soils after pathogen inoculation. The population of Glomus sp.(350/100gm soil) was maximum in soybean+ Glomus sp. inoculated soil and it was observed that VAM fungi and crop residues in combination suppresses the disease to maximum extent as compared to their alone effect and only 8.7 per cent disease index was recorded in apple seedlings inoculated with mungbean+ Glomus sp. followed by 16.03% in soybean+ Glomus sp. inoculated seedlings.

Abstract

Ten pests belonging to six insect and mite orders were recorded infesting strawberry cv. Chandler in Paonta and Doon Valleys of North Indian during 2001-04. Out of these Heliothis armigera Hubner, Spodoptera litura F., Thrips tabaci  Kheg, Holotrichia insularis Brenke, Odontotermes obesus Ramb and Tetranychus telarius L were of primary significance. Two fortnightly application of endosulfan (0.05%) from mid April proved effective in containing the attack of first two most devastating pests.

Investigations were undertaken to isolate the fluorescent pseudomonads from the soil and root samples collected from Western Ghats regions of Chikkamagalur district of Karnataka. A total of nine isolates were obtained from 10 sampling sites. All the nine isolates were subjected for morphological, physiological and biochemical characteristics and were tentatively identified as Pseudomonas fluorescens. Isolates were examined for different agriculturally important functions like production of plant growth promoting substances (PGPS), solubilization of TCP and biocontrol activity. Results of the study indicated that, five out of nine isolates found positive for IAA production and the amount of IAA production ranged from 1.92 to 6.75 mg per ml.

The livestock sector is one of the fastest growing agriculture sub sector in India, which accounted for about 17% of the value of agriculture output in 1981-83, has gradually increased by to 25% in 2011-2012 (CSO 2011, GOI). India possesses one of the largest livestock populations in the world with 218 million cattle, 115.4 million buffalos, 160 million goat, 75 million sheep, 9.4 million pigs, 947 million poultry (FAO, 2012) which provide excellent opportunities and boost rural income and alleviation of poverty. The country has 16.5% cattle, 56.8% buffalo, 5.78% sheep and 14.76% goat population of the world. India stands first in milk production likely to be touch142.6 MT in 2014 with 4.5% annual growth rate of milk.

Management of Angora rabbit includes important aspects of breeding, feeding, heeding and disease control.

8.1. Reproduction

Angora rabbits of lighter breeds reach breeding age of 6-7 m, medium rabbits at 7-8m and heavier breeds at 8-10 m. Female Angora rabbits do not have a true oestrus cycle with a definite heat period. They may mate at any time of year. Ovulation in does is induced by mating and occurs about 10 -12 hours later to mounting and copulation with the bucks. No doubt there is no definite heat cycle in Angora rabbits, yet during certain periods breeding does are more receptive to bucks than other times of the year. Some of the signs of such receptive period are restlessness, rubbing of chin on the feeding or watering bowls and vulva may be slightly swollen and purplish red.

Important by-products from rabbits are meat, wool, planner and skin. It can be made highly profitable if products are wasted because people do not have enough knowledge about their processing.

11.1. Slaughtering and Dressing

    1.    Rabbits are killed by one of two methods. The preferred method is dislocation of the neck. The rabbit is held firmly by the rear legs and head; it is stretched full length. Then with a hard, sharp pull, the head is bent backward to dislocate the neck. The rabbit can also be struck a hard, quick blow to the skull behind the ears. A blunt stick or side of the hand is commonly used to incapacitate the rabbit. Both methods quickly render the rabbit unconscious.

The sources of contamination of milk on the farm can broadly be categorized as

    a)    Interior of the Udder
    b)    Exterior of the Udder.
The interior reflects the health of the animal, while the exterior depends on the farm condition, equipment, persons, water etc.

a) Interior of the Udder
The animal by itself is one of the most significant contributors of microorganism in milk. The bacteria in the udder usually enter from the teat opening and get distributed internally by their own growth and physical movement. In the normal healthy udder, the types encountered in milk are most predominantly Micrococci, followed by Streptococci, Corynebacterium and others. Most of the bacteria are excreted in fore milk.

In India, the collection, transport and distribution of raw milk involves a number of agencies and persons at rural and urban level – village producers, milk collectors, halwais (Sweet-makers), milk vendors, dairies, producer-retailers and wholesale or retail markets.

1. Collection

Usually, the milk collectors approach the small village producers to collect milk and the same is sold directly or indirectly (through agents) to a dairy (milk procurement centres) or halwais or city milk vendors or consumers. The producer – retailers themselves, in some cases, supply the milk to the above said parties. The production of milk in small, scattered holdings in village causes problems during its collection. It involves visits to many villages, some of which are not easily accessible for the purpose.

According to International Dairy Federation(IDF),1980, Mastitis also called as ‘mammitis’ is defined as an inflammation of the udder, almost always of microbial origin and is the outcome of a local or a general infection. The common symptoms are related to inflammation, viz., swollen, hot, red, and painful udders. Mastitis can be classified based on symptoms or on the causative organism.

A) Forms of mastitis based on symptoms

    1.    Acute or clinical
    2.    Sub-acute or subclinical
    3.    Chronic.

Poultry industry in India has a strong standing globally, being third highest egg producer with more than 50000 million eggs and fifth highest broiler producer with 2.25 million tones of broiler meat. Largely, Indian poultry industry is chicken dominated and the rearing of high yielding varieties under intensive rearing system is the backbone of its present face. Analysis of trend of egg production in last five years i.e. 2001-2006 revealed that annual growth rate in egg production is about 5-6 %, except a much lower rate of 3 % during 2003.

Livestock sector may be considered as a driving force for nutritional security and an important component of sustainable agriculture in India. Livestock sector besides providing milk and meat also provides a diverse range of output for agriculture (manure, draught power and transport) and for manufacturing sector (fiber and leather). According to estimates of the Central Statistics Office (CSO), the value of output from livestock sector at current prices was about 4,59,051 crore during 2011-12 which is about 24.8% of the value of output from total agricultural and allied sector at current price and 25.6% at constant prices (2004-05). The value of output of milk is 3,05,484 crore in 2011-12, which is higher than the value of output of paddy and wheat. The value of output from eggs and wool group is 17,803 crore and 318 crore respectively for 2011-12. Livestock agriculture is the only way to produce food in many of the world’s harshest environments. Locally adapted breeds enable these vast areas to be used in a sustainable manner.

5.1 Concept of Ecosystem

Ecosystem is the basic functional unit in ecology, since it includes both biotic and abiotic environments influencing each other for maintenance of life.

A.G. Tansky in 1935 first proposed the term ecosystem. According to him, it is defined as the system resulting from the integration of all the living and non-living factors of the environment. In a simplest form, an ecosystem can be defined as a self-sustained community of plants and animals existing in its own environment. The term ecosystem is composed of two terms, “eco” means environment and “system” means an interacting and interdependent complex. It is otherwise known as bio system.

9.1 What are Natural Disasters?

The natural disasters are earthquakes, floods, droughts, famines, heat waves, cyclones, wild fire, volcanic, aerosols (small particles), and landslides.

9.2 Disaster Management

Both physical solutions and institutional strategies should be developed to manage natural disasters. For flood disaster control the water flow should be checked. Institutional strategies do not rely on physical barriers and include flood plain management, flood and disaster warning systems, education and preparedness programmes.

To meet the food needs of the burgeoning population, India will need to produce 300 million tonnes of food grains by 2020. At present more than 75% of the total food grains produced in the country are of rice and wheat. Use of nitrogenous fertilizers has contributed much to the remarkable increase in production of rice and wheat in India that has occurred during the past three decades. During the last half-decade or so while fertilizer N consumption is touching new heights, the production of both rice and wheat is showing a trend of plateauing. In fact, fertilizer N efficiency of food grain production expressed as partial factor productivity of N (PFPN) has been decreasing exponentially since 1965. The PFPN is an aggregate efficiency index that includes contributions to crop yield derived from uptake of indigenous soil N. fertilizer N uptake efficiency, and the efficiency with which N acquired by the plant is converted to grain yield. A decrease in PFPN occurs as farmers move yields higher along a fixed N response function, unless other factors shift the response function up. In other words, an initial decline in PFPN is an expected consequence of the adoption of N fertilizers by farmers and not necessarily bad within a system’s context

Ever since industrial revolution altered the whole gamut of economic activity at least two hundred years ago, the path of economic growth including its modified form economic development had appeared unending and limitless. The whole focus of economic activity is to produce mere goods and services for use by the mankind so that life could be more comfortable and satisfying. Increasing population and increased needs of more goods and service was also seen as a hindrance or limitation in the march towards economic growth and development.

Q.2.    Statistical power is the probability that a statistical test will indicate a significant difference is true i.e. it is the probability of taking correct decision.

It is difficult to ascertain which came first, food or human being. It is the same situation as chicken and egg where we lack evidence to indicate which came first on earth.

It does not matter which came first but we know for sure that human being needs food and he or she needs everyday and throughout his or her life. In other words, a human being cannot survive without food indicating permanent unbreakable bondage between food and human being. It supports the basics of human civilization-food, agriculture and humanity.

SYNOPSIS

Human health is defined as a state of physical, mental, physiological and social well being. It is also considered as a state of body and mind, where there is a balance of body humors or secretions. The paper introduces the readers to common diseases caused through various agents like deficiency disorders, food and water, air-borne, vector, viruses, and life-styles. It also describes healthy food, health management, food management, and healthy life style.

On different occasions I have expressed my views on hunger and food security. Here are some of the views published earlier.

1. Food Security bill: Why it is an opportunity lost

Several years ago I and Dr M S Swaminathan were speaking at a conference on hunger at Rome. Also speaking at one of the sessions was the Brazilian Minister for Zero Hunger Programme, the dream programme of ex-President LuizInácio Lula da Silva. After he had listened to us, he sat down with us to know of how India was battling hunger, specially the way India was managing its food self-sufficiency and the massive food procurement programme.

Jasmine (Jasminum spp) is one of the oldest fragrant flowers cultivated by man. They are the most common flowers in India gardens.

Importance and Uses

They are traditionally important flowers not only as fresh flowers but also as source of high grade perfume oil. Mention of jasmine is there in ancient Indian literature like Kamasutra (AD 300-400) and Mahabharatha (500 BC). The odour of jasmine flowers cannot be imitated by any known synthetic chemical or natural isolates, thus giving it a unique status in the perfume world.

Marigold is one of the easiest annual flowers to cultivate, having wide adaptability. Flowers are attractive, have good keeping quality with a wide spectrum of colour, shape and size. They produce marketable flowers in a short time and are used widely for religious and social functions as well as for garden display. 

Importance and Uses

 Marigolds are sold as loose flowers, as cut flowers and widely used for various decorations and garland making. They are also excellent landscape plants widely used for bedding purpose, in herbaceous borders and can also be grown in pots. French marigolds, being dwarf, are suitable for hanging baskets, rockeries, edging and window boxes. In fact, marigolds rank next only to jasmine in popularity in South India 

National Horticulture Board

Commercial floriculture includes production of cut flowers, foliage plants, bedding plants and growing and forcing bulbs and corms of flowering plants for whole and retail sales. The floriculture industry has become highly specialized. Floriculture industry uses many devices to ensure steady supply of flowers and foliage plants irrespective of the season and minimum loss to industry, because of perishable nature of flowers.

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.

Tamil Nadu Irrigated Agriculture Modernisation and Water Bodies Restoration and Management project (TN IAMWARM) is a multidisciplinary project funded by World Bank. It is being implemented by WRO, PWD as nodal agency in 63 sub basins along with line departments and TNAU as coordinating agency since 2007. TNAU is concentrating on up scaling water saving technologies including Sustainable Sugarcane Initiative (SSI) under Precision farming in sugarcane. Krishi Vigyan Kendra, Virinjipuram is implementing TN IAMWARM project in Cheyyar & Kiliyar sub basin since 2007. Cheyyar  and  Killiyar Sub - Basin are the tributaries  of the Palar Basin that rises in KolarDistrict of  Karnataka enters through Vaniyambadi  and drains an area of about 13,470 Sq. K.M. of which 10,880 Sq. K.M. is in Tamil Nadu. The command area of this sub basin comes under the Cheyyar and Vandavasi Taluk in Thiruvannamalai and Uttermerur, Maduranthagam, and Seyyur Taluk in Kancheepuram Districts  which covers 458 tanks in 12 blocks with a registered ayakut area of 36746 ha. The major crops grown in the sub basin area are paddy, sugarcane, groundnut and pulses.

Vegetables constitute about 55 per cent of horticultural crop production in the country with a total production of 85 million tonnes which is estimated to cross 100 million tonnes in near future. Successful cultivation of vegetables is hampered due to the incidence of several insect pests. Cultivation of hybrids, improved varieties, intensive agronomic practices, off season cultivation and indiscriminate use of insecticides has changed the pest complex in these crops.

Krishi Vigyan Kendra is a Government of India funded Indian Council of Agricultural Research Project implemented at district level for enhancing the productivity and livelihood through scientific extension works. Realizing the importance of technology dissemination in the changing scenario of food and nutritional security, ICAR intervened in a big way. All the first line extension projects were merged and brought under single umbrella of KVK. The major emphasis was to enhance the production and productivity as well as to generate household income and employment of farming community. It was also envisaged that these extension works will be act as model for extension agencies and also catalyzed to improve the existing systems for better delivery mechanism.

The cropping pattern in India is changing fast, particularly in favour of export-oriented commercial crops. These crops pose threat to the environment. Grapes is one such crop which accelerates environmental degradation. Borkar (2007) reported that with the advancement of technologies, the cultivation practices of grapes had improved increasing the yield and quality of grapes. However, to control the tremendous losses occurred due to pests and diseases in grapes, thousands of hundreds of kilograms of pesticides were dumped into the environment causing pollution.

Animal husbandry contributes 30 percent of agricultural gross domestic products in India and hence remains an important livelihood activity to the growing population of India. Mixed and diversified farming provides significant profit to the farmers than either only with agricultural or livestock farming. One of the biggest challenges in animal production is to produce animal products for human consumption through sustainable technologies. In the southern districts of Tamilnadu, dairy farming, sheep and goat rearing and back yard poultry form the major livestock livelihood activities.

The digital revolution is radically shifting how people create, manage, share and publish information, as well as how they relate, collaborate, communicate and share resources. Information and Communication Technologies (ICTs), Social Media, Web 2.0 and mobile applications have also significantly changed the livelihoods of the local farmers especially in developing countries.

The transfer of technology keeps the wheels of agriculture development moving. The existing transfer of technology mechanisms and extension programs are either slow or ineffective in bridging the linkages between the research community and the farmers. Information Communication Technologies (ICT) in agriculture is an emerging field focusing on the enhancement of agricultural and rural development. The advancements in ICT can be utilized for providing accurate, timely, relevant information and services to the farmers, thereby facilitating an environment for more remunerative agriculture.

In India, self employment has been recognized as an essential force of development in rural areas. It has emerged as a strategy designed to improve the socio-economic life and mainly focuses on extending the benefits of development to the poorest in the rural areas improving their standard of living and self-realization. SHGs in India are integrating the low income segments with rest of the rural community by ensuring them a better contribution in a more equitable share in the benefit of developments. These Groups are not only speeding up economic growth, but also providing jobs and improving the quality of rural life towards self-reliance. Self-employment needs a very wide ranging and comprehensive set of performance, relevant to all aspects of rural economy and covering rural people including skilled, unskilled and landless labours and artisans of Rural India. The Rural Indians put their entrepreneurial skills in all the rural development performance  but their economic status has not improved to the expected level. They have much potential, despite they are ignorant of converting their skills into reality.

Information Technology can play an important role in disseminating agricultural information to the farmers by using various multimedia sources. Farmers are more desirous and anxious to get quick, accurate and authentic information in the changing scenario of agriculture at local and at global levels. Dissemination of the required and recent agricultural information to the farmers in scattered villages at the variegated geographical situation in India is very difficult task. Transfer of technology to farmers is not a one time exercise because new farm technology is being constantly evolved. A continuous flow of technologies in an appropriate manner is vital to provide quick benefit for the development of the farmers. There has been a technological explosion in the field of agriculture. This demands that the farmer has to know all aspects of technology prior to its adoption. Hence Interactive Multimedia Module (IMMM) has potential to reach the unreached.

The Indian agriculture is on the threshold of a second revolution. It is becoming increasingly clear that the next leap will come from the Information and Communication Technology (ICT). Even though ICT has developed very well, its penetration to the farming community seems to be very less. At the same time, it is difficult for the extension agent to personally attend the queries of every farmer individually. With the decreased number of extension workers, there is a need to use the latest technologies for delivering extension services.

Women hold up half the sky’ according to Chinese saying. This is true with the Indian scenario as well, since women make up half the country’s population. The rural women in India constitutes nearly 77.00 per cent of the total female population. About 79.00 per cent of rural women workers are involved in agriculture related pursuits as cultivators and labourers. Farm & home are integral parts in the rural society in India and the ‘house wifes’ in the farmstead often plays multiple roles as producer, entrepreneur, workers, consumers, and homemaker. Women are more sensitive than men to the extremes of poverty and its consequences.

There are 437 tribes in India and Andhra Pradesh is inhabited by 33 tribes. Of these, 13 tribal groups  inhabit in high altitude zone of Visakhapatnam. Livelihood security is the ability of a household to meet its basic needs like food, health and shelter, basic education and community participation. Livelihoods can be made up of a range of on-farm and off-farm activities which together provide a variety of procurement strategies for food and cash.

Cassava is one of the leading staple food crop which is consumed as food and rest is used in industries and as feed to animal. Cassava has the potential to increase farm income, reduce rural and urban poverty and help to close the food gap (Nweke et al., 2001). It is used in many sectors like food processing, textile industries, glucose production etc. Salem stands first in area and has about 650 sago and starch industries acting as a prime reason for the intensive area under the cassava cultivation in Salem also 60 per cent of the starch produced in India comes from Salem District alone. Nearly 200 products can be made from cassava which leads to implementation of several interventions in the district which helped in imparting knowledge on cassava value addition techniques and improve adoption. Present study was undertaken to analyse the perceived impact by focusing on the effect of interventions of CTCRI and TNAU among the women growers in enhancing group approaches and empowerment through entrepreneurship activities.

Climate change referred as, a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods (IPCC, 2001). In other words, it is any long term conspicuous deviation from usual prevailing climate bringing variations in normal temperature, rainfall, atmospheric circulation with abnormal expression in extreme climate such as floods, droughts, extreme temperature etc.

In conventional agriculture, spatial variability over the landscape is ignored and fertilizers, herbicides, insecticides, fungicides etc. are applied at a uniform rate throughout the crop field. Precision Farming emphasizes on the infield variability which is first recognized, located, quantified and recorded, then managed by applying farm inputs  in specific amounts at specific time and at specific locations.

Vedic literature indicates that the energy in the universe gets transmitted into the human body through star galaxies. The star galaxies of our universe are divided into 27 parts each signified by a particular star (nakshatra). Every human being is assigned to a particular star by virtue of his birth time.  Each star is associated with a tree. The tree associated with his star gives the universal energy to the human being. Thus astrology gives us a chance to identify the tree which is auspicious to us, being associated with our birth star. When one plants the tree associated with his birth star near his dwelling, it will bring good luck and prosperity to him.

The relative abundance of both the species were almost the same in cultivated hosts whereas, D. ciliatus was more abundant in wild hosts.

Introduction

The libraries of 2020 become multi-media centres of information resources, leaving behind their dull and drab image of repositories of old dusty books materials like micro-films, audio and video cassettes. Various electronic products for use both off line and on line representing the special type of materials need special equipments of different makes for their effective use.

Introduction

The library and information centre is an important component of any educational institution. It is a hub of specific information where the end users can explore the vast resources of information. In the era of old age libraries users had to spend more time for searching a small piece of information and for that had to depend on library professionals. But now we are living in the age of information and communication technology, computers are being used for day-to-day work of library which saves the time of users and avoid the redundancy work of library staff.
