The field experiment conducted to evaluate the potentiality of organic farming in groundnut-wheat cropping sequence in terms of productivity, profitability and soil health on clayes soil during 2010, 2011, 2012 & 2013 at Junagarh (Gujarat) revealed that application of farm yard manure (FYM) and vermicompost (VC) recorded significantly higher pod yield (1786 and 1665 kg ha−1) and haulm yield (3147 and 2978 kg ha−1) of groundnut as compared to recommended dose of fertilizer (RDF), while RDF and VC recorded significantly higher grain yield (4332 and 3885 kg ha−1) and straw yield (6404 and 5967 kg ha−1) of wheat. Maximum net return and B:C ratio were obtained with FYM in groundnut and recommended doze of fertilizer (RDF) to wheat. Overall maximum net return and B:C ratio from groundnut-wheat cropping system were realised with FYM. Application of organic manures to groundnut-wheat sequence significantly improved bulk density, organic carbon content, post harvest soil fertility, and increased uptake of N, P and K over RDF.
