Productivity of Different Cropping Systems as Influenced by Resource Conservation Techniques

The field experiment was conducted on loamy sand soils of Agronomy Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar (Gujarat) during the years 2012-13 and 2013-14 to study productivity of different cropping systems as influenced by resource conservation techniques. Cotton-summer pearlmillet cropping system was found significantly superior by recording higher pearlmillet equivalent yield and nutrients profitability, while, water productivity, water profitability and nutrients productivity were found higher under greengram+Kharif castor (relay) cropping system. Greengram-mustard-summer pearlmillet recorded the highest agro-energy. Residue incorporation secured top position by recording significantly the highest pearlmillet equivalent yield, water productivity, water profitability, nutrients productivity, nutrients profitability as well as agro-energy. The application of 75% RDN through inorganic fertilizer+25% RDN through FYM recorded significantly the highest pearlmillet equivalent yield, water productivity, water profitability, nutrients productivity, nutrients profitability and agro-energy.
