Abstract

A field experiment was conducted to study the effect of different doses and method of phosphate solubilizing bacteria (PSB) application and the phosphorus levels on sunflower and chickpea during Rabi, 2020 at College of Agriculture, PJTSAU, Rajendranagar, Hyderabad. The experiment was laid out in Randomized Block Design, comprising eleven treatments with three replications. Initial soil parameters of experimental site indicated that the soil belongs to sandy loam texture, with alkaline in soil reaction, non-saline, low in organic carbon (OC), low in available nitrogen, medium in available phosphorus, available potassium and available sulphur. The results indicated that there was an increase in soil fertility status viz., organic carbon (%), available nitrogen, phosphorus, potassium and sulphur with the combined application of the Phosphorus Solubilizng Bacteria (PSB) and Phosphorus (P) fertilizers over the single application of the P levels. Within the PSB application significant results were obtained with the Soil application compared to the drenching.

Keywords: Available nutrients, drenching, phosphorus, solubilizing bacteria, soil application
