![]() Similarly, these dual traits bacterial strains were more effective than single trait strains under soil conditions (pot trial) in increasing root weight (up to 3.9-fold) and root elongation (up to 3.8-fold), dry shoot weight (up to 37.6%), number of tillers (up to 56%), grain yield (up to 38.5%) and P uptake in grain (up to 77.4%) of wheat grown in the presence of P applied as diammonium phosphate (DAP), RP (rock phosphate) or RP-enriched compost. Under axenic conditions, the bacterial strains with dual plant growth-promoting activities were superior in improving growth of wheat as compared to the strains possessing single trait. Bhakar-2002 using rock phosphate (RP) as an exclusive P-source. Six Bacillus strains having predominantly either ACC deaminase activity (KA1 and KA2) or P solubilizing activity (KP3 and KP4) or simultaneously both of these traits (KAP5 and KAP6) were evaluated for improving growth of wheat cv. ![]() having any one of these traits for improving growth, yield and P uptake by wheat crop. ![]() simultaneously carrying dual traits such as P solubilization and ACC deaminase activity with Bacillus spp. The aim of this study was to compare the effectiveness of Bacillus spp.
