This study was conducted to investigate effect of iron and sulphur application on growth and yield of soybean. Two levels of iron (15 and 20 mg kg−1 soil) and sulphur (40 and 80 mg kg−1 soil) were applied as split dose application on soybean var PK-327 individually and in combination. Positive effect of iron and sulphur application was observed on different investigated parameters viz. shoot height, root length, number of leaves plant−1, chlorophyll content, leaf nitrogen content, number of pods plant−1, length of pods, growth analyses parameters, 100 seed weight and seed protein content. The findings of the study suggest that judicious supplementation of iron and sulphur may improve growth and yield potentiality of soybean.
