In cotton moisture conservation techniques involving coir pith application in the sub soil layer at 60 cm depth and spacing using coir pith applicator found to increase the soil moisture by 7-8%. Weeding operation with power weeder resulted in 90% labour saving and 60% cost saving (ICAR 50 Crore).
Drip fertigation of 100% RDF (120:60:60 NPK kg/ha) as water soluble fertilizer with liquid biofertilizer and humic acid resulted in yield increase of cotton over soil application in system approach (ICAR 50 Crore).
Application of 120:60:60 NPK kg/ha combined with foliar nutrition of 1% Mono-potassium phosphate or 1% Poly feed at 75th and 90th days registered higher seed cotton yield, lint yield, ginning out turn and net profit (Sub Project).
Minimum tillage with crop residue application @5 tons/ha and supplemental drip irrigation given three times during the crop growth period had significant effect on soil moisture content, plant height, yield attributes and yield of rainfed maize and cotton.
Broad Bed Furrow system with crop residue as a mulch@ 5 tons/ha registered higher soil moisture at different soil depth, Rainfall use efficiency, yield attributes and yield of rainfed maize and cotton in Vertisol.
