Effect of Phosphorus Solublizing Bacteria (PSB) on Growth and Yield in Tomato

A field experiment was conducted to study the effect of phosphate solublizing bacteria (PSB) on growth and yield of tomato. PSB culture was applied through soil and seedling ischolar_main dip before transplanting with two levels of phosphorus fertilizers, i.e., 75% and 100% of recommended P, and compared. Results revealed that application of 100% P with seedling dip in PSB 1:10 solution recorded significantly higher plant height (86.30cm), leaf area index (3.52), number of fruits/plant (16.32), fruit weight (77.75g), fruit yield/plant (1125g) and yield (392.26 q/ha) compared to other treatment combinations, except 100% P with 5kg/ha soil application of PSB. The same treatment also recorded the highest (3.41) cost:benefit ratio. However, no significant difference was noticed in 100% recommended P with seedling dip in PSB solution, or soil application.
