Effect of dual inoculation of salt tolerant Rhizobium and PSB in cowpea

Abstract

A pot culture experiment was conducted to evaluate the effect of salt tolerant Rhizobium and PSB on growth and nutrient uptake of Cowpea (cv. Phule Pandhari). The inoculation with isolates of Rhizobium and PSB in combimation showed significant increase in growth parameters viz. seed germination, plant height, number of branches per plant, dry matter weight, nitrogen and phosphorus uptake per plant. The inoculation of Rhizobium (RHB5) x Phosphate solubilizing bacteria (PSB4) recorded significantly more germination percentage, growth character, nitrogen, phosphorus uptake and microbial population in soil over absolute control.
