SUMMARY

 A field experiment was conducted at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) to study the effect of tillage and integrated nutrient management on sorghum productivity during kharif season of 2009.  Results, showed that conventional tillage recorded significantly higher plant height, dry matter accumulation, yield attributing character, yield, gross, net return and B.C. ratio over minimum tillage. Among the INM treatments RDF recorded significantly higher plant height at 25 DAS, dry matter accumulation at all stage of crop growth, yield attributing character, yield, gross, net return and  BC ratio of crop over rest of the treatment. When RDF was applied with conventional tillage, it was found significantly superior over reduced tillage and minimum tillage in terms of grain yield.
