Abstract

A field experiment was conducted during 1998 and 1999 kharif season to study the seed yield and yield and percent content of protein and uptake of nutrient by greengram ( Vigna radiata (L) Wilczek ) as influenced by different levels of fertility and sources of sulphur. The experimental soil was Inceptisol, neutral in reaction, low in organic carbon, available nitrogen, sulphur and zinc and medium in phosphorus and potassium. Application of higher level of fertility (37.5 N: 90 P2O5: 5.0 Zn Kg/ha) to greengram gave the maximum seed yield (11.28 q/ha), protein yield (3.01 q/ha), protein content (26.51 %), uptake of 48.18 kg/ha N, 5.92 kg/ha P, 22.76 kg/ha K, 2.79 kg/ha S and 87.87 g/ha Zn with minimum production cost one kilogram seed Rs. 6.90 and higher Benefit Cost Ratio 1: 2.70 in pooled results. In case of sulphur sources, the highest seed yield 11.18 q/ha, protein yield 2.96 q/ha, protein content 26.29 %, uptake of 47.26 kg/ha N, 5.75kg/ha P, 22.19 kg/ha K, 2.73 kg/ha S and 85.26 g/ha Zn were recorded under ammonium sulphate in two years pooled results, whereas, single superphosphate produced one kilogram seed of greengram at a minimum cost of Rs. 6.57 with highest Benefit Cost Ratio 1: 2.82.
