Phosphorus and Sulphur Nutrition with P-Solubilizing Bacterial Inoculation Enhanced the Quality and Yield of Soybean (Cultivar JS-335)

Abstract

Field experiment was conducted to assess the response of soybean (cultivar JS-335) to phosphorus and sulphur nutrition with phosphorus solubilizing bacterial inoculation on yield and quality of grain. The results of two years studies revealed that yield attributes, seed and straw yield were increased with the application of sulphur and phosphorus with phosphorus solublizing bacterial inoculation than without phosphorus solublizing bacteria. However, application of 40 kg/ha significantly influenced the yield attributes and yield over its preceding doses. Numbers of pods per plant, seeds per pod, seed index, seed, straw and biological yield were also significantly increased by 40 kg P2O5/ha with phosphorus solubilizing bacterial inoculation over its lower levels. Hence, it is apparent that soybean production may be enhanced by the application of sulphur at 40 kg /ha and phosphorus at 40 kg P2O5/ha with phosphorus solubilizing bacterial inoculation.
