Abstract: The research was conducted during Zaid season of 2014 at Experimental Farm, Annamalai University, Annamalainagar to find out the experiment consisted of two different spacings (30 cm × 10 cm and 45 cm × 6.7 cm), three sources of nutrient (100% Organic, 50% Organic + 50% Inorganic and 100% Inorganic on the basis of N and K) and three methods of Zn application (No application, Soil application at 12.5 kg ZnSO4 ha-1 and foliar spray at 0.5% ZnSO4) which was laid out in Factorial Randomised Block Design (FRBD) with three replicates. Thus, there were 18 treatment combinations in total. The result revealed that greengram grown during zaid season with the spacing of 30 cm × 10 cm along with nutrient sources 50% Organic (1.50 tonnes of Farmyard Manure ha-1 + 83.35 kg Bone meal ha-1) + 50% Inorganic (55.56 kg Diammonium phosphate ha-1 + 12.50 kg Muriate of Potash ha-1) and Soil application of Zn at 12.5 kg ZnSO4 ha-1, recorded highest number of seeds pod-1 which attributed in obtaining highest grain yield. In addition, highest net return as well as benefit to cost ratio was evaluated for the same treatment.
