Abstract:
A field experiment was conducted to study the effect of different doses and method of phosphate solubilizing bacteria (PSB) application and the Phosphorus (P) 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. Phosphate solubilizing bacteria was applied to soils with two different methods; 1) Soil application of lignite based powder form with two doses (3kg and 6kg per hectare) after mixing with vermicompost @ 1t/ha. This mixture was applied in sowing line. This source of PSB had 108 -109 viable colony counts per gram of PSB. 2) Soil application of liquid PSB biofertilizer with 50mL/L (8L per hectare) by drenching in the sowing line. The application of the NPK fertilizer as per the recommended dose of the sunflower and chickpea. The results showed that the effect of PSB and P levels on P uptake by shoot at different growth stages and seed at harvest of sunflower and chickpea had a significant effect and there was an increase in P uptake with the age of the crop. Among all the treatments, in sunflower highest P uptake was recorded in Treatment with 75% P application and soil application of PSB @ 6 kg/ha and lowest was recorded with No P level. whereas in chickpea, P uptake by shoot of chickpea was recorded highest with 50% P +PSB-SA2.
