The effect of mixed bacterial biofertilizers containing nitrogen fixers, phosphate solubilizers and potassium solubilizers was investigated against individual applications. One strain each of Rhizobium, Azotobacter and two strains each of phosphate and potassium solubilizers were isolated, prepared and applied individually while a consortium of the inoculum was prepared by mixing each strain with the carrier. Each preparation was applied as seed treatment to study their effects on beans and corn plants. The shoot length, pod size, flowering, stalk formation, yield and other growth parameters were monitored. The mixture of bacterial preparations enhanced the plants’ health, growth parameters and yield of beans and maize plants significantly at a significant value of p<0.05, when compared to the single bacterial applications and control. The results proved that the mixed biofertilizers increased the growth, and yield in addition to shorter crop cycle compared to the control and individual bacterial biofertilizers.

Abstract
The effect of mixed bacterial biofertilizers containing nitrogen fixers, phosphate solubilizers and potassium solubilizers was investigated against individual applications. One strain each of Rhizobium, Azotobacter and two strains each of phosphate and potassium solubilizers were isolated, prepared and applied individually while a consortium of the inoculum was prepared by mixing each strain with the carrier. Each preparation was applied as seed treatment to study their effects on beans and corn plants. The shoot length, pod size, flowering, stalk formation, yield and other growth parameters were monitored. The mixture of bacterial preparations enhanced the plants’ health, growth parameters and yield of beans and maize plants significantly at a significant value of p<0.05, when compared to the single bacterial applications and control. The results proved that the mixed biofertilizers increased the growth, and yield in addition to shorter crop cycle compared to the control and individual bacterial biofertilizers.
Author Keywords: Bacteria, biofertilizer, nitrogen fixers, phosphate solubilizers, potassium solubilizers, beans, corn, Leguminous and non-leguminous plants.
