Effects of phosphate solubilizing microorganisms and Rhizobium sp. on the growth, nodulation, yield and root-rot disease complex of chickpea under field condition

M Akhtar, Z Siddiqui

Abstract


Effects of Phosphate solubilizing microorganisms ( Glomus intraradices, Pseudomonas putida, P. alcaligenes, P. aeruginosa (Pa28), A. awamori) and Rhizobium sp. was observed on the growth, nodulation yield and root-rot disease complex of chickpea under field condition. Inoculation of Rhizobium sp. caused a greater increase in growth and yield than P. putida, P. aeruginosa or G. intraradices. The number of nodules per root system was significantly higher in plants inoculated with Rhizobium sp. compared to plants without Rhizobium sp. Inoculation of P. putida caused highest reduction in galling followed by P. aeruginosa, P. alcaligenes, G. intraradices and A. awamori while Rhizobium sp. caused almost similar reduction in galling as caused by P. putida.
