This study was conducted to assess the possible role of the integrated use of seed inoculation with plant growth promoting rhizobacteria (PGPR), compost and mineral fertilizers for improving growth and yield of wheat sown at different plant spacing. PGPR were isolated from rhizosphere soil of wheat plants. Four treatments were applied in the main plots viz., T1 (Recommended N as Chemical Fertilizer @ 120 kg per ha as Control), T2 (Recommended N as Chemical Fertilizer @ 120 kg per ha + Compost @ 250 kg per ha), T3 (Recommended N as Chemical Fertilizer @ 120 kg per ha + Compost @ 250 kg per ha + Inoculation with PGPR), T4 (Recommended N as Chemical Fertilizer @ 120 kg per ha + Inoculation with PGPR). Basal dose of P and K @ 100 and 60 kg per ha as Diammonium phosphate and murate of potash respectively was applied to all treatments at sowing time. Maximum increase in plant height, number of tillers m-2, and number of spikelets per spike, grain and straw yield were recorded with
