Abstract

A field experiment was conducted during kharifseason of 1998 and 1999 to study the effect of fertility levels and sulphur sources on yield, quality and soil nitrogen economy of mungbean. Higher level of fertility F2(37.5N: 90 P2O5: 5.0 Zn kg/ha) significantly increased the seed and straw yields from 9.30 to 11.28 and 20.34 to 33.26 q/ha respectively. The highest contents of 4.26, 0.523, 2.03, 0.246 per cent and 77.1 ppm of N, P, K, S and Zn respectively were obtained in seed under F2. An economy of 36 kg/ha in available N was recorded over initial available N of the experimental field under F2, which was higher by 11 kg/ha over available N content of F1 (lower level of fertility). Application of 30 kg S/ha to mungbean through ammonium sulphate gave significantly higher seed and straw yields of 11.18 and 33.26 q/ha respectively. Application of ammonium sulphate proved superior to gypsum and pyrite in content of nutrients of mungbean seed, but it was at par with application of single superphosphate for N, K and Zn contents. Available N content of alluvial soil wasnot influenced significantly by different sources of sulphur, however, ammonium sulphate gave 10 kg/ha more available N than pyrite and it was higher by 35 kg/ha to initial available N status of experimental soil.
