A field experiment was conducted on calcareous clayey soil at Junagadh (Gujarat) during rabiseason of 2014-15 to study the effect of phosphate and potash solubilizing bacterial inoculationson growth and yield of wheat. The experimental results revealed that application of 45 kg P2O5/ha + phosphate solubilizing bacteria (PSB) seed inoculation + PSB soil application, being statistically at par with application of 45 kg P2O5 + PSB seed inoculation, significantly promoted dry matter per plant, effective tillers, grains/spike and 1000-seed weight, and ultimately gave higher grain yield (40.1q/ha) and straw yield (60.2q/ha) with higher net return (`45256/ha) andB:C (2.10) over the control. Significantly higher values of growth and yield attributes viz., dry matter per plant, effective tillers and test weight were registered with application of 45 kg K2O/ha + potash solubilizing bacteria (KSB) seed inoculation + KSB soil application remained at par with application of 45 kg K2O/ha + KSB seed inoculation, resultantly gave higher grain and straw yield of 40.8 and 60.8q/ha, respectively along with higher net return (`46946/ha) and B:C (2.15) over the control. The results clearly indicated that PSB and KSB inoculation saved 25% P and K fertilizers.
