Achievements of Soil Research in Dryland Regions of Andhra Pradesh

Not AvailableThe global rainfed crop lands were estimated at 1.132 billion hectares at the end of the last millennium. This is 2.78 times the net irrigated areas (407 m ha) of the world. Rainfed agro-ecosystems occupy a considerable place in Indian agriculture too, covering 80 million ha, in arid, semi-arid and sub-humid climatic zones; constituting nearly 58% of the net cultivated area. Rainfed regions support 60% of livestock, 40% of human population and contribute 40% of food grains and several special attribute commodities. Rainfed agro ecologies are complex, diverse, fragile, risky, under invested and require regionally differentiated investments and management strategies. Achieving high production potential is difficult in these rainfed areas due to vagaries of rainfall.Not Availabl

Promising Technologies for dry land Agriculture

Not AvailableNatural Resource Management has important research agenda in view of the climate change, degradation of land and declining productivity in greenrevolution areas. Efficient methods of soil and rain water conservation and water harvesting become important areas of dryland agriculture research to achieve sustainability. Variation in crop yields is more in dry lands due to non receipt of timely rainfall and prolonged dry spells during crop periods. Adoption of soil and moisture conservation measures and improved management practices will help in getting higher yields.A large number of location specific practices for insitu moisture conservation, water harvesting and supplemental irrigation have been developed and tested successfully at All India Co-ordinated Research Project for Dryland Agriculture (AICRPDA), Agricultural Research Station, Ananthapuramu. Dryland Agriculture occupies a prominent place in rural livelihoods of Andhra Pradesh. In Andhra Pradesh out of 92.04 lakh ha of cultivable land an area of 34.56 lakh ha is under rainfed agriculture, mainly in scarce rainfall and southern agro climatic zones. AICRPDA, ARS, Ananthapuramu is continuing efforts to generate location specific technologies in the areas of rain water management, integrated nutrient management, cropping systems, farming systems, alternate land use and energy management.Not Availabl

Cholesterol assimilation, acid and bile survival of probiotic bacteria isolated from food and reference strains

The evidence shows that probiotics can reduce cardiovascular diseases associated to high cholesterol levels, but it occurs just when they survive gastrointestinal conditions. The aim of this study was to evaluate the ability of reference strains (RS) and food isolates strains (FIS) to survive acid and bile and to determine in-vitro cholesterol assimilation. FIS were more tolerant to acid than RS, showing significantly different growth response. FIS were more resistant to the presence of bile, in order descendent to oxgall, taurocholic acid, and cholic acid. The survival percentages ranged from 0% to 100%, presenting strain dependence. The most tolerant strains were tested for cholesterol test, showing RS lower percentages than FIS. In FIS, the percentage was negatively affected when the concentration of bile salt was increased. Therefore, to study the viability of different strains in gastrointestinal conditions is crucial because of the strain-dependence nature
