Consolidated effect of bacterial strains as bio-inoculants on growth of maize: a comparative approach

Syed Muhammad Zubair Younis, Tanveer Iqbal


Maize is third important crop grown in Pakistan contributing 2.2 percent to the quality included farming and 0.5 percent to GDP. Chemical fertilizers are frequently used in Pakistan which increases cost of production and give less profit to the farmer. In this study two main bio-inoculants namely PGPR & PSB were used in-combination with chemical fertilizer to compare the effect of both as single/co inoculants on maize crop. A pot experiment was conducted where 9 treatments of bio-inoculants and chemical fertilizer combined/separately connected at the sowing time. Information was treated by ANOVA Least Significant Difference (LSD) test at probability level 0.05 was used to seclude the techniques when the ANOVA F-test showed a vital effect of treatments. The co-inoculation of PGPR + PSB + K + ¾N + ¾ P shows significant results among nine treatments of all parameters that were observed. So use of bio-inoculants can reduce the cost of chemical fertilizer with increase in production.
