Effect of phosphorus and Phosphorus Solubilizing Bacteria (PSB) on nutrient content and uptake by soybean crop

Abstract

A pot experiment was conducted during kharif, 2022 in the Net house of Department of Soil Science & Agricultural Chemistry, College of Agriculture, Junagadh Agricultural University, Junagadh to study the effect of Phosphorus and Phosphorus Solubilizing Bacteria (PSB) on soil phosphorus availability, yield and nutrient uptake by soybean. The experiment was laid out in factorial completely randomized design with three replications having 16 treatments combinations viz. 4 levels of phosphorus (0, 40, 60, 80 kg ha-1) and 4 levels of phosphorus solubilizing bacteria (PSB) (0, 1, 2, 3 l ha-1). Results revealed that nutrients like N, K and S content in seed and stover of soybean unaffected under the application Phosphorus and PSB. Whereas, the phosphorus content, significantly increased by the application of phosphorus up to 80 kg ha-1 and PSB 3 l ha-1. Nutrient uptake like N, P, K & S, is significantly increased by the application of application of phosphorus up to 80 kg ha-1 and PSB 3 l ha-1.
