Abstract

The study with different inorganic phosphorus doses and their combination with phosphorus solublizing microbes (PSM) had significant effect on growth, total microbial population of the soil and leaf nutrient status of Walnut cv. Govind. The treatment T₁₁ consisting of 84.37g P₂O₅ + PSM (80g culture) had maximum growth (16.87 cm) and also have a significant improvement in total microbial count (12,126) of the soil and leaf nutrient status of Walnut cv Govind.

Pressing Flowers

One of the most popular methods for drying flowers is to put them under pressure, to remove the moisture out while leaving the color of the flowers and structure intact. There are several ways to apply pressure to flowers. The easiest method is placing them in heavy books and allow for drying. Flower presses can also be used. Some guidelines for pressing flowers in the traditional way are explained below:

Methods of fertilizer application

Two major methods are used to apply fertilizers  
I) Application of fertilizers in solid form 
II) Application of fertilizers in liquid forms

While on one hand, more than 25 per cent of rural population in India is between 15 and 29 years of age, on the other, very little demographic dividend in agriculture is being derived. Unable to find decent employment, youth often look for employment in the urban informal sector, with poor working conditions and pay. But without training in skills suited to the urban labour market, these youth have few opportunities in the urban areas. Inadequately trained to compete successfully in urban labour market, they often suffer varying levels of poverty and marginalization in towns than in rural areas. In rural areas, if young farmers do not replace the ageing farmers, it will result in problems related to food security. For young people to take to agriculture, farming must be personally satisfying, mentally challenging, socially acceptable and economically rewarding. However, field reality is something different.

ABSTRACT

Successful in vitro clonal propagation of mature tree of Lasoda (Cordia myxa Roxb) has been achieved through single node explant. Both types of organogenesis of shoot and root formation were obtained by placing nodal explant on shoot induction medium and subsequently on rooting medium. More than 90% culture were responsive for in-vitro axillary shoot proliferation on MS media supplemented with 30g Sucrose 8.0 g agar and a combination of 2.0 mg BA and 0.1 mg NAA per litre. After culture period of 6-8 week, the nodal explants with micro shoot were rooted on the MS media supplemented with30 g Sucrose + 3g activated charcol and different level of NAA (0, 1, 3 and 6 mg/ litre). The season and position of explant on the mother plant was also shown to influence in vitro performance of the regeneration in terms of establishment of aseptic culture, percentage of responsive explants and intensity of leaching of growth inhibitory phenolic chemicals.

THEORETICAL ORIENTATION

One of the training methods used in management training and technical training is workshop method. The word workshop is borrowed from the area of industry. As the word says, in the workshop of industries, practical work is done by the workers. Similarly, through workshop method, some works are done by the participants who are actively involved in the same. One component which is common for all the methods is the person who conducts the proceedings of the method. We may call him a trainer or more appropriately for this method the director of the workshop. In using workshop method, the trainer needs a few experts who may be called as consultants or co-trainers. The trainer cannot handle the workshop situation single-handed.

A workshop schedule is very much important for planning an effective workshop method. It will help arrange all the necessary materials and the people well in advance to organise the workshop programme successfully and achieve the objectives of the workshop for which it is organised.

5.1. Irrigation requirement of field crops

Services for CSA

Under the CSA projects and programmes, the services like supply of inputs and technology transfer through extension services are provided to the farmers. The inputs like seeds of crops are provided by the input dealers at the subsidized rate and seedlings of fruits and vegetables are provided by both private and government agencies to grow under general cultivation and poly-house cultivation technology. Similarly other services like soil testing facilities, issue of soil health cards, construction of micro-irrigation projects and rain harvesting structures are made available to farmers. Under insurance scheme, loanee farmers are supported to pay premium dues for availing crop insurance facilities. Other services like trainings at various levels, demonstrations, exposure visits, exhibitions, kisan melas, field days, monitoring and evaluation of all these activities under these programmes are provided to the farmers with collaboration of extension officers.

Medicinal and aromatic plants constitute a precious resource for mankind. Since time immemorial these plants have been put to medicinal use by Hakims, Vaidas, Ayurvedic practioners and of course the common man (Gupta et al. 2016). It is because these plants possess a lot of qualities for curing the most common or dreaded diseases without any side effects (Gupta et al. 2016). Unfortunately, with the onslaught of human population explosion, industrialization, fertilization and deforestation, the rich medicinal plants wealth has suffered a massive damage. A large number of medicinal plants are now at the verge of extinction which requires their preservation.

India which stands blessed well vast medicinal plants diversity is estimated to have about 30,000 different plant species world over having accepted medicinal value in Ayurveda, Unani, Homeopathy, Allopathy, Tibetan etc. In fact, out of the 18 hot spots in the world with regard to occurrence of medicinal plants two are confined to India. These two hot spots are represented by the Eastern and the North western Himalayas, and the western Ghats with very high degree of endemism. These are indeed the treasure house of about 30,000 or around 45,000 medicinal and aromatic plant species pertaining to medicinal culture (Gupta et al. 2016). Out of these nearly 6000-7500 plant species have been very much exploited for the last 5,000 years traditional system to medicines and are likely to extinct.

In monetary terms, value-added’ per unit of the product is the margin between its selling price and cost of production. However, in the dairy and food industry, value addition refers to, extra, features of a product that are beyond the expectations of a consumer at little or no extra cost. In this context, the addition of value to milk can involve monetary value added to a liter of milk by turning it into milk products, enhancing the convenience of quality, shelf life, or health characteristics using processing and packaging interventions.

4.1. Conversion of Milk into Conventional Products

It is an age-old tradition to add value to milk by processing it into milk products. The primary aim was to increase the shelf life of milk that would otherwise be highly perishable. With inadequate facilities to preserve liquid milk fresh in the rural areas’ conversion of milk into a variety of milk products would be an ideal option to effectively preserve the huge quantities of milk procured during the flush season’ In the processing of milk products such as cream, butter, cheese and ghee, by-products such as skim milk, buttermilk, whey, and ghee residue are obtained’ Many of the dairy plants, particularly in India’ are usually confronted with the problem of by-products utilization, especially that of whey and ghee residue in an economical manner. Membrane separation processes have presented new possibilities for the production of newer intermediate products from dairy by-products that can be used for value addition in dairy and food industries.

There is urgent need to increase the production in order to meet the demand for the exploding population. This could be achieved by applying various modern methodologies in selection and breeding of livestock. Increasing the productivity through genetic improvement requires adequate identification and intensive selection of genetically superior sires. About 93 per cent of the total herd improvement comes from breeding of young bulls from tested sires and only six per cent from selection of dams.
With the advances in artificial insemination and cryopreservation of semen, a sire has a potential of serving 3/4th million cows and producing 1/4th million progenies.
Thus, selection of bulls is of great importance in dairy herd improvement.
For maximising the genetic gain by sire selection, it is essential that the method of estimating breeding values of sires should be unbiased and efficient. The breeding value refers to the average genetic effect of the genes passed on by the individual to its offspring and is estimated to know whether the individual is genetically superior to other individuals or not for the trait concerned.

The word banana is derived from the Arabic word “banan,” which means finger and it is known as “the fruit of the wise”. In the middle ages, the banana was thought to be the “forbidden fruit of paradise”. Bananas are the most popular fruit in the world. Members of the genus Musa are considered to be derived from the wild species Musa acuminata (AA) and Musa balbisiana (BB). It is not a tree, but a perennial herb the leaves of which are usually grouped together, forming a trunk-like structure called pseudostem. The origin of bananas is believed to be Malaysia or India. Bananas are a very important commodity for developing countries, with a clear dual nature as they are at the same time a major staple commodity and a fundamental export commodity. There are almost 1000 varieties of bananas in the world with lot of commercially recommended cultivars. The most commonly known banana is the Cavendish variety, which is usually produced for export markets.

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.

Drying by Embedding

A desiccant is simply a substance with a high affinity for water which can be used as a drying agent. Embedding the flowers in a granular, desiccating material is probably the most commonly used method and many consider it the best all around method. Several materials are used as drying agents. All the agents used vary in cost and in the results they produce. It is important to use the correct procedure when covering the flowers so that their form is maintained. Most well known is silica gel, but also clean dry sand can be used. Usually an airtight container is used; the flower heads are placed in the drying mixture face up, and very carefully covered with the mixture. The container must be kept closed during the drying process. After 4-14 days, depending on the thickness of the flower, the flower will be dry.

The Agriculture sector is by far the largest employer amongst all the major sectors employing roughly half of available workforce. At the same time, agriculture is the smallest sectoral contributor to the GDP. It is ironical that the most important requirement of human being, which is the bulk of agriculture farm produce, is largely considered to be an unrewarding sector in the nation.

Though the Indian agriculture has made significant strides in the course of the last 50 years of planned development, still the farmers today are facing the consequences of host of challenges, namely dependence of monsoon, declining size of land holdings, degradation of soil & water resources, declining investment of public sectors on agriculture. So farmers are increasingly getting indebted and temptation to sell their farm land  for non-farm purposes is growing. Over 45 per cent of farmers want to quit farming says a survey conducted by National Sample Survey Organization (NSSO).

Agricultural land is still a great source of income. But the practice of unsustainable methods and improper resource management leading to successive crop failures that make agriculture non- profitable and highly  risky.  So, the interest of youth in agriculture has been declining. While most developing countries are still experiencing high population growth rates, the youth are migrating in significant numbers to urban areas. The younger generation does not consider farming as a profession and they treat it as traditional activities of their family. The farm youth think that the farming system is not capable to provide a life, therefore they are diverting from agriculture to other profession.

Yak is among the most remarkable domestic animals. It is adapted to thrive in the harsh environment of high altitude and sustains livelihood of highlanders. Yak is handicapped because of lack of veterinary assistance and declining pastoral biomass. Marketing facilities for yak-based products are limited and the production potential of yak husbandry is on decline. Dearth of locally available trained manpower and prevailing illiteracy are other hindering factors for development of yak husbandry. Research and development with focus on upliftment of yak husbandry and yak products are therefore important.

Principle

RNA is negatively charged at neutral pH and when an electric field is applied, it migrates towards the anode. RNA retains much of its secondary structure during electrophoresis unless it is first denatured. The addition of formaldehyde to the agarose gel maintains the RNA in its linear (denatured) form. The following protocol is based on Formaldehyde Agarose Gel Method.

To allow the students for progressive training for the management of teaching situation.

To improve specific micro-teaching skills involved in teaching.

Introduction

India is often criticized for the negative externalities to the ecology due to the largest livestock population of the country. Thus inspite of the fact that the integrated farming system followed in the country contributes towards not only saving the resources and improving the environment. This study quantifies the positive environmental externalities associated with the livestock production in the context of integrated farming system of rainfed areas. It included land saving due to recycling of agricultural by-products as animal feed and also due to use of dung- cake as domestic fuel, saving of chemical fertilizers due to use of dung as manure and prevention of carbon dioxide emission due to use of animal energy in agriculture.
