Effect of different levels of phosphorus and sulphur on yield attributes, seed yield, protein content of seed and economics of summer greengram.

摘要

Field experiments were conducted in West Bengal, India, during the 2003 and 2004 summer seasons, to study the effect of phosphorus (0, 30 and 60 kg/ha) and sulfur fertilizer applications (0, 20 and 40 kg/ha) on the seed yield, pods per plant, seeds per pod, 1000-seed weight, protein content, total cost, net return and cost:benefit ratio of summer green gram. Green gram yield increased with increasing levels of P and S fertilizers. P at 60 kg P2O5/ha and S at 40 kg/ha gave the highest number of pods per plant, number of seeds per pod, 1000-seed weight, seed yield, net return and net return/rupee invested..
