Abstract

The Himalaya is one of the youngest and the richest mountain ecosystems encompassed with a variety of species of both flora and fauna. Varying in climatic conditions coupled with altitudinal gradients and unique topography leads to the formation of different types of forests, which varies from tropical to the temperate and alpine to no timber line zone and snow-clad meadows. The present study aimed to investigate the potential of medicinal plants growing in valleys and mountains of district Doda to cure various ailments of the local inhabitants including animal health care. A total of 113 species belonging to 104 genera and 55 families of angiosperms, gymnosperms and cryptogams (lycophytes and ferns) were recorded and reviewed from published documents used for treatment of different diseases in the regions. Out of the total 113 species, 17 species were of trees, 14 species were shrubs, 78 types of herbaceous plants and 4 species of climbers. Asteraceae, Lamiaceae, Rosaceae, Ranunculaceae, Polygonaceae, Solanaceae, Apiaceae, Pinaceae, Fabaceae and Berberidaceae were recorded as the dominant families of the study area. The data were collected while interacting with local people as they possess rich traditional knowledge regarding the use of different herbal plants and medicine.

Introduction

Arid and semi arid parts of the India are known as Seed Spices Bowl (Rajasthan and Gujarat) and contribute more than 80% of total seed spices production. Total 109 spices are listed by ISO and 63 spices are grown in India and out of which 20 are being classified as seed spices. Out of 20 seed spices, ICAR-NRCSS working on 10 most important seed spices namely cumin, coriander, fennel, fenugreek, ajwain, anise, caraway, celery, dill and nigella (NRCSS Vision, 2050). Seed spices also grown in some other states on considerable areas such as Uttar Pradesh, Madhya Pradesh, Bihar, West Bengal, Orissa, Punjab, Karnataka and Tamil Nadu. Since there is a large scope of seed spices by introducing them in new areas, the higher yields can also be achieved effortlessly by implementing new technologies. Among seed spices, maximum area is under cumin followed by coriander, fennel fenugreek, ajwain, celery, nigella, dill, anise etc. Being seasonal crops, these are grown extensively in rotation with food crops and also as inter/mixed crops under rainfed/irrigated conditions. All these crops mostly grown in rabi season. India is the largest producer, consumer and exporter of seed spices in the world. Out of total area and production in spices, seed spices contribute about 51.79% of total area and 19.06% of production of spices in the country. The area under seed spices is about 1.74 million hectare and 1.45 million tonnes. India is consistent source of seed spices for importing countries worldwide. There has been ever increasing demand of seed spices and importing countries look at India for quality produce of seed spices.

Introduction

Vegetables are one of the potential crops in meeting the food requirements and improving the nutritional status of our people. They play a vital role in crop diversification, employment generation, and nutritional security and in improving the economic conditions of farmers.

Our country has made a tremendous progress in vegetable production and ranked as second largest producers of vegetables in the world with a total production of more than 125 million tons per annum. Our estimated demand is about 225 million tons by 2020 AD. This target can be achieved through use of improved vegetable varieties, hybrids and production technologies even with diminishing land and water resources.

In Indian vegetable scenario, IARI has contributed significantly by developing more than 168 improved varieties and 24 hybrids in different vegetables. Apart from high yielding, many of these varieties/F₁ hybrids are resistant to biotic and abitic stresses and also suitable for processing, value addition and export. Besides developing large number of improved varieties and F₁ hybrids of vegetables, IARI has developed/standardized improved hi-tech vegetable nursery and off-season production technologies which require commercialization by the entrepreneurs as these can bring quantum improvement

Abstract

Greenhouse vegetable cultivation is gaining popularity for reasons such as high productivity of quality produce round the year with enhanced input use efficiency. As agriculture has a major share in our economy and if India has to emerge as an economic power in the world, the productivity should substantially increase from the present levels. We need a new and effective technology which can constantly improve the productivity, profitability and sustainability of our major farming systems. One such technology is the green house vegetable production technology. At Indian Institute of Horticultural Research, Bangaluru, research on greenhouse vegetable production is in progress since the year 2000, resulting in the development of many technologies which have made possible to realize high yield levels in tomato, capsicum and cucurbits that are comparable to international standards of greenhouse productivity. Tomato and bell pepper yields have touched 300 tonnes and 200tonnes/ha/year, respectively and cucurbits 80 to 100 tonnes/ha/crop of 3 months. Vegetable cultivation in cost effective greenhouse is a technical reality in India, which is being adopted by resourceful farmers in and around big towns and cities as a peri-urban horticultural system. Such production systems have not only extended the growing season of vegetables and made their availability round the year but also opened the possibilities of growing new vegetables such as coloured capsicums, cherry tomatoes, seedless watermelons, icebox melons, sweet cucumbers, coloured cabbage, etc., besides tomato, cucumber, eggplant and climbing beans. Quality seedling production is one more important greenhouse activity in the present agricultural scenario as more and more F₁ hybrids are being adopted by the farmers.

High Yielding Variety Programme (HYVP)

High Yielding Variety Programme (HYVP) was launched in 1966, which helped the country in attaining self-sufficiency in food. The technological development did not remain confined to the introduction of high yielding crop varieties alone. These were combined with the application of high analysis and balanced fertilizer, irrigation, plant protection, improved implements etc. which made a ‘Green Revolution’possible in the country.

India is the second-largest producer of fruits in the world after China. However, the average productivity of fruits in India could be higher compared to many developed countries. The main reasons for low productivity are old and senile orchards, low-yielding varieties, poor orchard management, and inadequate technological upgradation and adoption by the growers. Presently, due to urbanization and population explosion, there is a continuous decline in the availability of cultivable land; rising energy and land costs, together with the increased demand for horticultural produce, have given thrust to the concept of high-density planting (HDP) in fruit crops. However, at the same time, it is now realized that there is limited scope for a quantum jump in fruit production in traditional areas. Therefore, the alternative is to expand under non-traditional regions like arid and semi-arid areas of the country. India’s hot arid and semi-arid regions are spread mainly in Rajasthan, Gujarat, Andhra Pradesh, Telangana, Punjab, and Haryana. The vast land resources offer an excellent opportunity for fruit production in the Indian arid zone, which is spread over about 31.70 m ha, of which 41.50% is arable and 19% is a cultivable wasteland (Table 1).

High-pressure processing (HPP) is a novel method for non-thermal preservation technique of food that inactivates harmful pathogens and vegetative spoilage microorganisms. HPP is an alternate, non-thermal food processing method, wherein the food is subjected to a very high pressure range from 100 -800 MPa (1MPa = 145.03 Psi or 10 Bar). HPP is also referred as High hydrostatic pressure processing, Ultra high-pressure processing, Hyperbaric processing and Pascalization (Rao et al., 2014).

8.1. Biofloc aquaculture

Among the innovations in the field of aquaculture, biofloc technology (BFT) has attracted great attention due to its ability to foster the goals of sustainable aquaculture (Khanjani et al., 2022a). If implemented correctly, BFT capitalizes on the existing organisms in water to significantly reduce water use and environmental impact and increase biosafety at farms (Avnimelech, 2012).

Abstract

Rural indebtedness is an old problem in India. In the 19^th century commercial banking was absent in rural areas and farmer were entirely in the hand of usurious moneylender. Since the British rule, the central government has been trying to extend institutional lending to the rural agriculture sector. To provide credit to the agricultural sector, a multi-agency approach involving co-operative banks, scheduled commercial banks, and RRBS has been used in India. Adequate and timely loan availability at reasonable rates is the basis for agricultural finance policy. The institutional structure for agricultural lending has improved over time in terms of scope and reach. India’s higher education institutions have been focusing their efforts on advancing agricultural finance.

Definition

Fracture of humerus bone and femur bone are generally categorised under higher level fracture.

Methods Used For Fracture Repair

These level fractures are repaired appropriately by intramedullary pinning and Thomas splint application.

Only pinning or only Thomas splint are not the method for its repair as the distal fragments of bone get tourqed by pinning only and the fracture fragments get distracted by simple Thomas splint application.

Hence after pinning a humerus or femur bone, the limbs are kept immobilised perfectly by Thomas splint application.

When pinning as well as Thomas splint application are not possible the fractured bones are kept immobilised with fevicol gum bandage only. So for this purpose modification of velpeau sling is generally adopted and animal is restrained within limited space for 21 days.

Definition

Any fracture or discontinuity in bony structure like scapula and pelvic girdle present above the shoulder joint and hip joint respectively are called as highest level fracture.

Aim

To know the method of repair of highest level fracture.

Procedure

As there is no satisfactory method of external immobilisation till date, generally animal is kept under restricted movement. Sometimes application of charge (glue bandage) externally may give some satisfactory result.

INTRODUCTION

According to analyst firm Gartner, Big Data is at the portion of the hype cycle called the "peak of inflated expectations." The business world is awash with all sorts of claims about the magic of Big Data and how it will transform industries by increasing productivity and profits and opening up opportunities that nobody even knew existed. But this will only happen if companies are able to hire enough people who actually understand what Big Data is, how to collect it, and preserve it. Computing and analytical skills are also required to get Big Data to reveal its hidden secrets and visualise it in novel ways. And there unfortunately, is the rub. There are just not enough data scientists, people with the required skills to satisfy this unmet demand. The shortfall in Big Data experts is set to rise and in the UK alone, one digital industries employer body has predicted there will be a need for 69,000 of these experts in the next five years. This claim is not original. Back in 2011, McKinsey & Co was claiming a US shortfall in Big Data experts of 140,000 - 190,000 by 2018.The shortfall in Big Data experts is being manifested in a number of ways. The first and most obvious is through recruiters casting an ever-widening net in their search for appropriate talent. There is some agreement that Big Data analysis and data visualisation requires skills in computing as well as statistics and mathematics. This has meant that university graduates with statistics, computer science and engineering have been the main source of potential employees. Lately this has widened to include subject areas such as astrophysics and computational chemistry.

INTRODUCTION

Assam is a heartland of indigenous groups. Since hundreds of years, many indigenous groups have been living in the state, maintaining their originalities in every sphere of life with difficulties. The tribal-indigenous groups constitute almost 12.4% of the total population of Assam. (Sentinelassam.com). Fishing is one of the major livelihood option of many indigenous fishers as the state is blessed with huge water resources with about 3.91 lakh hectare of water area in the form of rivers, beel, derelict water bodies and ponds and tanks. Besides swamps and low-lying areas, two major rivers and their tributaries have a high growth potential for fishing and could play a pivotal role in the socio-economic development and employment generation in the state. Indigenous fishers have developed a close and unique connection with the water resources and its environment in which they are depended for generation to generation for their livelihood. They have generated unique system of knowledge, innovation and skills relating to the uses and management of fishing activities. Over centuries, people have learnt how to get food and to survive in different environment. Farmers are very keen to observe the problems arising during fishing and seek solutions to adjust to their local environmental conditions. They continuously adapt and manage their fishing systems and in this way, they develop a rich storehouse of practical knowledge on their situation.

Technologies for cultivation of crops are changing over the years. Adherence to the principles of conservation, high input-use efficiency and higher productivity with optimum inputs and the very idea of crop production as a business venture; all these are leading to increased adoption of high technological (high-tech) crop production practises.

Besides diversities and advantages in hills, the communities sustain largely on subsistence farming due to following constraints A.Natural constraints in hills There are large number of Inherent limitations in hill agriculture like, remote areas, vulnerability, marginality , eroded soil and short growing seasons. These Inherent constraints can be judged by the use of unsustainability indicators of hill agriculture which further showed increased in soil erosion rates from sloping farmlands , leaving of agricultural land due to decreasing soil fertility, appearance of stones and rocks on the cultivated lands, reduction in forest and grazing areas and more emphasis on monocropping that widened the cycle of inadequate food production and lead to food insecurity and increasing unemployment and frustration (Table 3) (Shrestha, 1992). These natural constraints are.

Pulses occupy an important place in hill agriculture. They are complementary to cereals in production and consumption being an important source of protein and nitrogen fixing ability which helps in improving soil health. Thus, cultivation of pulses has a positive relationship with our environment, human health and food security. Pulses produced in the hills are famous for their cooking quality, taste and flavour.
 
Himachal Pradesh has emerged as a model hill state in which agriculture is a dominant economic activity and major source of employment and income to the rural people. Being a hilly state, agriculture is practiced on about 10% of the geographical area. Out of which nearly 80% is rainfed. During the last three decades, the farming scenario has changed significantly. The area under fruits, vegetables and cereals has increased tremendously at the cost of pulses and oilseeds. There is, therefore, an urgent need to reverse this trend as pulse cultivation will not only increase soil health but save precious foreign exchange.

ABSTRACT

Plants play an important role in human survival and contribute to sustainable development as they are the major source of different bioactive compounds such as taxol, digoxin, reserpine and vinblastin used directly as drug and medicines for human diseases. As plants are basic need and requirement for living, they are used as herbal remedy, and known to produce lead compounds for semi synthesis of higher activity or lower toxicity. Indian Himalaya regions are repository of more than 8,000 plants species and out of which 50% are endemic and unique due to thepresence of morphological and chemical structure of peculiar characters. Most of the plant used in Indian traditional system of medicines such as Ayurveda, Unani, Siddha or Amchi described for different formulations and ethnomedicinal applications had distributional range restricted to the hills and the valleys of Himalayas. Hence, in this communication, an attempt has been made to present economic plants of Himalayan origin used as ethnomedicine, wild food plants as vegetables, herbal teas, homemade soups, wild salads, chutney, underground snacks, alcoholic drinks, nutrients as burnt powder and other human usages. Besides, this unique Himalayan plant has potential to be used as wild source for the development of new drugs and medicines which can sustain future to human survival and had the ability to produce medicine against deadly diseases. It is estimated that 80% of the world population uses traditional medicine made from herbal botanicals to cure disease and illness. It is of the record that 122 compounds obtained from ethnomedicinal plants is globally used as drugs. This indicates that tribal knowledge on plants and drug discovery cannot be separated, and newdrugsfor uniquedeadly diseases can be discovered only from ethnobotanical leads. More than 5,000 species reported from Indian Himalayas are of ethnobotanical values and they are used as medicine or wild food by different tribal communities. It can be concluded that Himalayan tribals are endowed with strong culture associated with botanicals and have age-old tradition with respect to the use of wild plants as food and medicine. Plants provide a real substitute for the primary health care systems in hills and valleys, and definitely going to serve as jewel for mankind in near future to come.
