Abstract
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 the management of cropping systems for resource conservation. Cotton-summer pearl millet cropping system was found significantly superior by recording higher pearl millet equivalent yield, gross returns, net returns, BCR and economic efficiency, while production efficiency was found the highest under greengram-mustard-summer pearl millet cropping system. Residue incorporation secured top position by recording significantly the highest pearl millet equivalent yield, gross returns, net returns, BCR, production efficiency and economic efficiency. The application of 75% RDN through inorganic fertilizer+25% RDN through FYM recorded significantly the highest pearl millet equivalent yield, gross returns, net returns, production efficiency and economic efficiency. In the case of BCR, 100% RDN through inorganic fertilizer was found significantly superior.
