Effect of various levels of Sulphur, nitrogen and phosphorous on growth and yield of soybean under Jatropha based agroforestry

Abstract

An experiment was conducted at the Forest Nursery of the Sam Higgibottom University of Agricultural Technology and Sciences Allahabad, India during the kharif 2017-18 to evaluate the Effect of various levels of Sulphur, nitrogen and phosphorous on growth and yield of soybean (Glycine max. L.) under Jatropha based Agroforestry. The study was revealed that the growth parameters like plant height (84.22), No. of Branches (13.55), Dry weight. (46.47) And yield parameters like No. of pods(93.09), No of seeds per pod (5.35), Test weight (95.15) seed yield (26.29), Stover yield (42.15) and harvest index (38.87) were significantly increased with the treatment T9 (100% N + 100% P + 50% S). The treatment T3(50%N + 100% P + 100% S) was statistically significant and at par to treatment T9. The treatment T0 (control) is recorded the lowest values of all treatments regarding to growth parameters and yield.
