Abstract: On farm trials (OFTs) were conducted for consecutive two years during 2011-12 and 2012-13 to assess the optimum sulphur levels of soybean with respect to growth, yield attributing characters, productivity, protein content and economics involved under Malwa plateau conditions of Central India. Soybean variety, JS 95-60 was taken to assess three levels of sulphur (0, 20 and 40 Kg S/ha). Treatment RDF+ 40 Kg S/ha found to be optimum level of sulphur as this treatment recorded significantly higher soybean root nodulation, yield and yield attributing characters, oil and protein content over 0 and 20 Kg sulphur/ha. This treatment also expressed its superiority over rest of the treatments in case of B: C ratio and net return. Thus, it may be concluded that application of RDF +sulphur @ 40 kg per ha was found economic feasible and beneficial for enhancing soybean productivity in Vertisols under rainfed conditions of Madhya Pradesh.
