Abstract/Description: | District Database of Agricultural Statistics was updated by including latest available statistics on land use classification (9 fold), source-wise net irrigated area and crop-wise area sown, production and yield and area sown with irrigation. • Homogenous agro-climatic zones were delineated for crops viz., finger millet, sesamum and castor. Crop-wise districts having high unreaped yield potential (yield gap) were identified. • Under RAINS, Database Management System (DBMS)wasdevelopedtoretrieve cropinformation, salient achievements of the projects by theme wise, production system wise, year wise and period wise. AICRPDA website domain name was registered as www.aicrpda.in and hosted. Climate Change • In the regional analysis of rice yields for Eastern region using different varieties, soil series under A1B climate change scenarios, it was found that in all the cases late sown rice varieties (Sarjoo-52, Mahamaya and MTU1010) gave higher yields. • In a field experiment to estimate the greenhouse gas emissions in castor and blackgram, it was found that CO2 and N2 O flux were relatively higher from castor than from blackgram. CO2 fluxes increased with age of the crop and maximum fluxes were recorded at vegetative stage and gradually declined thereafter. Maximum amount of N2 O fluxes were observed after fertilizer application. • GHG emissions were found to decrease by 26 and 12 % in ZT and RT over CT. Castor grown on pigeonpea residue recorded 20 % higher GHG emissions over pigeonpea grown on castor residues. The fuel consumption in ZT was reduced by 58 and 81 % as compared to CT in pigeonpea and castor, respectively. It was found that there is scope to reduce the NGHG emissions by reducing one tillage operation (RT) and crop residue by harvesting at 10 and 30 cm height with minimal impact on the crop yields. Rainwater Management • Hydrologicalmodeling of awatershed of 47 km2 area in the Krishna basin in Mahabubnagar was carried out for assessing the rainwater harvesting potential using the input layers of soil map, LULC, Slope and DEM. A farm pond of 500 m3 capacity was also constructed and lined with 500 micron HDPE geo membrane in order to achieve management module on integrated water resources. • Districts with significant area in during rabi season for different crops were identified. Out of 419 districts identified to be dominant for rabi areas for prospects of groundwater recharge, 72 districts had extremely low to very low ground water recharge prospects. Another 97 districts had the low prospects for groundwater recharge during the 2015 monsoon. • The analysis of rainfall data to estimate the harvestable water across different regions revealed that the higher differencein intenserainfall amounts between normal and drought years indicate less availability of runoff for mid and downstream regions as a major portion of harvestable runoff would have been tapped in upstream regions. • Watershed development management activities were initiated at farmers’ fields to demonstrate different soil and water conservation and recharge technology which includes bore-well recharge, farm pond and percolation. • A methodology was developed to find potential locations to construct different in-situ and ex-situ soil and water conservation interventions in semi-arid watersheds for interventions like RFDs, ponds, check dams, nala bunds etc. by applying the selected criteria using GIS. • The results of maize field experiments with polymer indicated that the application of 25 kg/ha PAM |
