GEOTHERMAL ENERGY AND LIVESTOCK PRODUCTION
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.
Mechanized Paddy Transplanting Impacts on the Productivity and Sustainability of the Rice Cultivation System in North West IGP: A Review
North Western Indo-Gangetic plains of Asia place a premium on maintaining its rice producing systems for the sake of food security and economic development. In addition to agricultural inputs, social and environmental variables contribute to this productivity boost. To address these new issues, innovative and lucrative solutions that minimize waste of resources and financial resources have been developed. The soil health, the subsurface water table, and the release of greenhouse gases that contribute to global warming are all threatened by the high resource requirements of traditional rice transplanting. There are labour shortages during transplanting because agricultural workers have left the industry to find higher wages in the metropolis. The low plant density of the conventional transplanting approach necessitates the use of supplementary inputs like fertilisers and insecticides, which drives up the cost of production and decreases harvest yield. In these conditions, rice transplanting must not only be cost-effective, but also labor-efficient, all without compromising the expected crop yield. Mechanical paddy transplanting (MPT) improves crop yields and guarantees timely planting. Mechanical rice transplantation is simple and profitable. Although growing mat-type nurseries outperform conventional transplanting methods, they have low field acceptability because of high entry barriers and a lack of expertise. With the use of technological knowledge, rapid availability, and specialized employment, farmers may be able to apply automated transplanting. Rice seedlings may be easily transplanted into soils with varying textures using MPT, which is an environmentally benign and climate-smart technique. It helps increase the profitability, sustainability, and production of rice farms while decreasing their carbon footprint. This review looked at the positive and negative effects that using mechanical paddy transplanting to deal with a lack of labor had on NW IGP rice yields, profits, and sustainability, and then identified the gaps that need to be filled for wider adoption.
Impact of enzyme supplementation in broiler chickens
This study was carried out to assess how the addition of enzymes to broiler diets composed of soya bean and maize impacts their performance. A total of 144 day-old Vencobb broiler chicks were divided into eight groups consisting of nine birds each, with two replicates. Experimental diets were formulated based on the NRC (1994) guidelines. Multi-enzyme supplements containing cellulase (400 units/g), xylanase (2000 units/g), pectinase (600 units/g), and protease (2000 units/g) were prepared and added to the feed at a rate of 500 g/ton. The experimental period was 42 days. Live weight gain and feed consumption were determined at weekly intervals. The enzyme supplementation did not show significant variation in mean body weight gain among treatment groups at 3rd and 6th week of age even with the reduction in energy and protein intake. The feed intake was significantly lowest (P < 0.01) in T7 at 3rd week of age, whereas, significantly lowest (P < 0.01) feed intake was recorded in T3 and T7 at 6th week of age. Significantly lowest FCR was observed in T2 and T4 at 3rd (P< 0.05) and 6th week of age (P< 0.01). A net profit of Rs. 4.94 (T4) and 3.97 (T3) per bird was obtained by reducing the energy level by 5 to 10 per cent. It can be concluded that the addition of enzymes to diets based on soya bean and maize improves the performance of broilers with low protein and energy, thus improving the revenue of the farm.
Varietal Susceptibility of Okra [Abelmoschus esculentus (L.) Moench] Against Shoot and Fruit Borer
Eleven varieties of okra were screened and none of the variety was found completely free from the attack of shoot and fruit borer. On the basis of shoot damage, the varieties, Versha Uphar and Arka Anamika were ranked as least susceptible. The varieties Hisar Naveen, Hisar Unnat, Arka Abhay, Pusa Makhamali, Aprajita, Kashi Mohini and Parbhani Kranti, ranked as moderately susceptible, while Sagun and Pusa Sawani were ranked as highly susceptible against shoot borer. On number and weight basis of fruit, the varieties Varsha Uphar and Arka Anamika were rated as least susceptible, Hisar Naveen, Hisar Unnat, Pusa Makhamali, Arka Abhay, Aprajita, Kashi Mohini, Parbhani Kranti as moderately susceptible, whereas, Sagun and Pusa Sawani as highly susceptible against fruit borer.
The effects of supplementary pollen diets on population, growth, and performance of honey bee
Honey bees occupy a prime position among all the pollinating agents because they can be managed in artificial nests, i.e. hives and can be placed in desired numbers. In Himachal Pradesh, the beekeepers migrate their colonies to other places during winters due to scarcity of bee flora. To keep the honeybee colonies strong during dearth periods different pollen substitutes and supplement need to be evaluated as a part of good management practice for beekeeping. Various ingredients were used such as defatted soya-flour, wheat flour, yeast, gram powder, skimmed milk various grain flour, sugar, honey etc. These mixtures were used in different ratios to evaluate their influence on colony parameters of A. mellifera L. The colonies were fed on various pollen substitute and supplement diets by frame feeding method at 14 days interval during rainy-autumn and spring-summer season. All the pollen substitutes were accepted by A. mellifera colonies and the consumption rate within 14 days varied in the range of 80.62% to 97.65% during both the seasons. A significant increase in brood area (1.61 times), honey stores (3.41 times during rainy-autumn, 2.87 during spring–summer) and pollen stores (1.77 times during rainy-autumn, 1.43 during spring–summer) was observed over control. On the basis of these studies, it was suggested that various pollen substitutes showed positive effect on colony parameters and honey stores of A. mellifera as compared to control.
