Efficacy of Commercial Phosphate Solubilizing Bacteria Ami PSB on the Growth of Solanum tuberosum L

This study aimed to evaluate the effect of commercial phosphorus solubilizing bacterium, Ami PSBTM, Bacillus sp., on the growth of potato.A Randomized Complete Block Design (RCBD) with three replications was employed in a field experiment conducted during two seasons (2021/2022 and 2022/2023).The treatment group was administered a commercial Ami PSB application to the soil, while the control group did not receive any treatment.Results revealed significant enhancement in various plant growth parameters with commercial PSB application.The treated plants demonstrated a 40% increase in plant height, a 62% increase in branch number, and a 40% increase in shoot dry weight compared to the untreated plants.Furthermore, phosphorus availability in the soil was substantially improved by the application of Ami PSB TM , resulting in up to a 57% increase compared to untreated soil.Significantly, the absorption of nutrients by potato tubers exhibited a notable enhancement, with a recorded 44% rise in plants treated with Ami PSB TM .
