Yield Attributing Characters and Yield of Mungbean Crop as Affected by Phosphorus, PSB, and Vermicompost

Abstract

Pulses cover a vast area of the Bundelkhand (UP) and Mungbean is prominent among the pulse crops and it is grown on a larger scale using local varieties entirely in dryland conditions and on residual soil moisture and fertility. In Bundelkhand, farmers grow the crops traditionally and without considering the scientific recommendations. Inorganic fertilizers (synthetic) are an important source of plant nutrients but their continuous and injudicious use posing health and environmental complications. Minimum use of inorganic sources of nutrients and rely on integrated nutrient management is the way to tackle the health and environmental issues due to imbalance and excessive use of inorganic nutrients. Phosphorus, PSB and vermicompost are found to play very important role in boosting the yield of legume crops. This research is, therefore, taken into account to evaluate the response of Mungbean crop to phosphorus, PSB, and vermicompost. The leguminous crops require more phosphorus as it is required for energy transformation in nodules. Phosphate solubilizing bacteria (PSB) is assumed to have greater significance because it helps to convert insoluble organic phosphates into simple and soluble forms. Vermicompost is a better and rich source of N, P, K, and micronutrients. Besides, containing a good proportion of exchangeable Ca, Mg, Na, etc., vermicompost enhances organic carbon to the soil and meagerly helps to release of nutrients and in turn uptake is improved. A field experiment was performed during Kharif season, 2019 at Agriculture Farm of Banda University of Agriculture and Technology Banda, Uttar Pradesh, India. Results of the study reveals that the basal applications of 75 kg DAP, 5 t Vermicompost (VC) ha-1 and seed treated by Phosphate Solubilizing Bacteria (PSB) led to a significant increase in yield attributing characters and yield and gave by 22.57% more yield advantage than the farmer’s practice. However, the application of higher doses of DAP with VC and PSB gave luxuriant growth to the crop rather than increased yield.
