Peer review
A field experiment was conducted to study the effect of Azotobacter chroococcum and Azospirillum brasilense inoculation under graded levels of fertilizer nitrogen (0, 30, 60, 90, 120 kg/ha) on wheat (Triticum durum Desf. var. HD2189). The results revealed that both the inoculants significantly increased the growth parameters viz. tillers, dry-matter accumulation, grain yield and protein content of wheat gains. Fertilizer—N @ 90 kg/ha with both inoculations was found to be the most responsive, however 120 kg/ha with Azospirillum inoculation recorded maximum number of tillers (3.5/plant), dry-matter accumulation (13.5 g/plant), grain yield (41.9 g/ha) and protein content in grains (13.3%). Maximum percent increase in grain yield with Azospirillum (25.8%) and Azotobacter (19.2%) over uninoculated control was observed at 90 kg N/ha level. Azospirillum inoculation, Azotobacter inoculation and uninoculated control significantly differed between each other.
