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 during Rabi, 2020 at College of Agriculture, PJTSAU, Rajendranagar, Hyderabad, Telangana, India.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, and low in organic carbon (OC), low in available nitrogen, medium in available phosphorus, available potassium and available sulphur.The results showed that the sunflower growth parameters were not markedly influenced by either PSB or Phosphorus levels when applied alone but had significantly improved the growth of sunflower.Combined application of PSB and reduced P levels had significant effect on the sunflower seed yield.The study indicated that application of Phosphorus @ 67.5 kg ha -1 along with soil application of PSB @ 6kg ha -1 produced the highest seed yield of 23.79 q ha -1 over all the other treatments and also highest oil yield (925.81 kg ha -1 ) than the other treatments.The above study indicated that combined application of PSB with reduced P levels could help in saving fertilizer dose to the extent of 25%.
