Women are the backbone of the rural economy and are bestowed with countless skills that not only boost rural economy but also contribute income and overall growth of the family. Skills and knowledge are the motivating factors for the upliftment of community as well as economic growth of a nation. The percentage of female population in India is 48.04% compared to 51.96% male population while as in J&K, women constitute 47% of the total population. In the Union Territory of Jammu and Kashmir, Jammu is the most populous district with population 15,29,958 and having an area of 2,342 sq km. A case study was conducted during the year 2022 to identify the entrepreneurship skills of rural women of Jammu district. Two blocks from the Jammu district namely Nagrota and R.S.Pura were taken and four villages on the basis of highest population from each block were selected and then five households from each village engaged in skill based activities were surveyed to find out the skills of rural women which was based on primary data collected through pre-structured schedule. The study confirmed that the average maximum income of skilled rural women of Nagrota block was Rs.7,800/month whereas that of R.S.pura block was Rs.16,800/month. The skills in rural women like pappad making (30%), cutting and tailoring (40%), beautician (10%), teaching(private) (5%), and salesperson (10%)in Nagrota block and cutting and tailoring (35%), teaching(private)(30%), beautician (20%) and dairy farming (5%) in R.S.Pura block was seen, along with their household activities. For making rural women more empowered, schemes like Self Help Groups(SHG), SAATH, UMEED, TEJASWINI, Government Loans and NGO’s have been started by the Govt.
Abiotic stress to plants is an important issue globally, particularly due to heavy metal pollutants, salinity, and drought. Many problems could be caused by these stresses, including the production of reactive oxygen species, membrane damage, loss of photosynthetic efficiency, etc. These problems could alter crop growth and development by affecting biochemical, physiological, and molecular processes, leading to a significant loss in productivity. Grapevines are no such exception. With this background, a study was conducted to evaluate the salinity tolerance of Thompson Seedless vines raised on Dogridge rootstock with varying levels of salinity viz., 0, 0.25, 0.5, 0.75, 1 and 2% NaCl. Salt stress resulted in reduced vegetative growth, chlorophyll and protein content whereas an increase in phenol and proline concentration was recorded due to stress-tolerance adaptive mechanisms. The concentration of sodium and chloride increased in vines whereas potassium concentration decreased. The concentration of sodium ranged from 0.14-0.69% in leaves, 0.09-0.28% in canes and 0.14-0.55% in roots and the chloride levels were 0.45-74, 0.26-60 and 0.43-1.21% in leaves, canes and roots respectively. However, the potassium content of vines grafted on Dogridge ranged from 1.20 to 0.78% in leaves, 0.97 to 0.30% in canes and 0.84 to 0.63% in roots. Elevated salt stress resulted in an increase in soil electrical conductivity, sodium and chloride concentration whereas reduced potassium content. The soil available nitrogen and phosphorus content also decreased due to reduced microbial diversity and microbiological activity essential for the process of nitrogen mineralization and precipitation of phosphorus with Ca2+ and Mg2+ cations. The tolerance index of Thompson Seedless grafted on Dogridge rootstock was recorded to be 102.36 (shoot/root dry weight basis). The use of tolerance ratios and tolerance indices can be an effective evaluation technique to test different rootstocks for salt tolerance.
Principal component analysis and cluster analysis were carried out at Tamil Nadu Rice Research Institute, Aduthurai to identify diverse sunnhemp genotypes for biomass yield and suitable genotypes for yield and yield-related parameters. In order to determine the relationship and genetic diversity among 67 sunnhemp genotypes a field study was conducted at Tamil Nadu during Kharif, 2021. Multivariate analysis such as principal component analysis, cluster analysis have been analysed using R software. Phenotypic analysis revealed significant genetic variability among the accessions for biomass yield leading to identification of several promising accessions. Cluster analysis and PCA grouped the 67 sunnhemp accessions into four clusters. Cluster I and IV are highly divergent harboring contrasting accessions. Plant production traits such as plant height, leaf breadth, basal stem diameter, yield and number of leaves had the majority contribution in the first two principal components.
The experiment was conducted at the Tamil Nadu Rice Research Institute, Aduthurai, Thanjavur, Tamil Nadu, India during summer season 2023 with an objective to study the impact of nutrient management and microbial consortia practices on machine transplanted rice on ADT 56 variety. The experiment was laid out in randomized block design with 10 treatments which are replicated three times. The experiment was carried out assigning four age of seedlings (12, 15, 18, 21 days old seedlings), two methods of planting viz., machine and normal. Mat nursery was prepared for 8 row Yanmer transplanting machine. The result revealed that mechanized transplanting with 15 days old seedling with 100% RDF + Microbial consortia recorded higher shoot length (17.3 cm), plant height 114.7 (cm), number of panicles (383/m2), No. of grains/panicle (255/panicle) and grain yield (5747 kg/ha) whereas 21 days old seedlings with no fertilizer showed decrease in grain yield (3056 kg/ha). Higher net income (62009 ₹/ha) and B:C ratio (2.2) was recorded in 15 days old seedling with 100% RDF and application of Microbial consortia respectively. Microbial consortia: Azatobacter vinelandii MAZO 36 + Phosphorus Solubilizing Bacteria + Arbuscular Mycorrhizae fungi + Potash Releasing bacteria + Zinc solubilizing bacteria (Nursery + Main field).
Livestock sector is one of the big enterprises in India and world, which is being commercialized and atomized continuously. Access to reliable supplies of energy is one of the main preconditions for the development of dairy industry and is a key determinant of their competitiveness. With growing concern about climate change and the need to reduce the use of fossil fuels, there is increasing interest in the use of renewable energy. In this regard, geothermal energy is one of the options that can be exploited in countries that are endowed with this resource. Geothermal energy is the heat stored in earth crust and is a clean, sustainable and renewable resource that provides energy using heat derived from the earth. India is in low geothermal potential region (medium range of 100-180oC and less than 100oC is low enthalpy). Geological Survey of India (GSI) has identified estimated geothermal potential of 10,000 MW in India. Different geothermal energy sources are hot water reservoirs, natural steam reservoirs, geo-pressured reservoirs, hot dry rock etc. Geothermal heat can get up to earth's surface though different kind of systems like flash power plant, dry steam power plant and binary power plant. Direct uses of geothermal energy are appropriate for sources below 1500C and can be used for drying, greenhouses, aquaculture, hot water, space heating, air conditioning industrial purpose, resorts and pools, melting snow etc. In livestock sector, geothermal energy is being used in rendering, chilling abattoir products, processing animal by-products, milk processing and livestock treatment and it can used as good source of energy for livestock production like in power operated appliances, feed & fodder treatment, heating & cooling of animal shelter, cleaning & sanitizing of animal shelter, sterilization of dairy equipments etc. Thus, geothermal energy provides clean, an efficient and economic source of energy, has direct and indirect implications and extensive experimentation needs to be undertaken at various geothermal locations to capture and capitalize the geothermal energy.
