Effects of Phosphate Solubilizing Bacteria and Mineral Phosphates on Hyola 401 Yield and Yield Components
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 7
Abstract
Comparison of the means showed that the effects of bacterial inoculation on number of seeds per pod, number of pods on the main stem, and seed yield were significant at the 1% probability level. Moreover, rates of phosphate application had significant effects on all traits but plant height and height of harvest by combine at the one percent level. Comparing the means of the effects of inoculation on seed yield indicated the maximum seed yield (2610 kg/ha) belonged to the treatment of inoculation with Pseudomonas putida, which was not significantly different from that of simultaneous seed inoculation with both putida and fluorescens strains (2473 kg/ha). The minimum seed yield was that of the treatment in which seeds were not inoculated (2224 kg/ha). Comparing the means related to the effects of phosphate application rates on seed yield indicated the largest seed yield (2840 kg/ha) was achieved at 75 kg/ha, and the smallest (1810 kg/ha) when phosphate was not applied. Comparison of the interaction effects of inoculation and phosphate application revealed that the highest seed yield (2980 kg/ha) was obtained in the treatment of simultaneous inoculation with both P. putida and P. fluorescens and phosphate application rate of 75 kg/ha. This highest seed yield was not significantly different from that of the treatment in which phosphate was applied at 75 kg/ha. The lowest seed yield (1480 kg/ha) was observed in the treatment of inoculation with P. putida without phosphate application, which was not significantly different from that of the treatment of no inoculation and no phosphate application (1600 kg/ha).
