Abstract

A field experiment was conducted during 2010-11 and 2011-12 at Jabalpur, Madhya Pradesh to study the impact studies of different resource conservation practices on rice and wheat equivalents, total productivity, production efficiency, water use efficiency and economics of 4 cropping systems viz. CS1, rice (Oryza sativa L.) - wheat (Triticum aestivium L.), CS2 rice – berseem (Trifolium alexardrinum L.), CS3 maize (Zea mays L.)- wheat and CS4 sorghum (Sorghum bicolor L.)- wheat. The rice – berseem cropping system recorded the highest total productivity in terms of rice equivalent yield (t/ha/year) and found 29.31%, 29.02% and 8.58% higher than the maize – wheat, sorghum – wheat and rice – wheat cropping systems, respectively as well as the production efficiency of former cropping system was 29.64, 20.63 and 10.69 percent higher over maize – wheat, sorghum – wheat and rice – wheat cropping systems. Rice and wheat equivalents were higher by 3.6 and 2.8 percent under conventional tillage over minimum tillage. Though the total productivity and production efficiency were lower under recommended dose of fertilizer (RDF) than the RDF+25% N through organic source but net returns and benefit: cost ratio was higher.
