Abstract

Common bean, Phaseolus vulgaris L. c.v. Shalimar Rajmash has been considered as a poor nitrogen fixing plant compared to other legumes. Even though there are several attempts to produce better varieties for improved N2 fixation, no work has been done to evaluate the response of this crop to different biofertilizers under various levels of phosphorus. The present investigation was carried out to study the effect of different biofertilizers namely Rhizobium Azotobacter and Arbuscular mycorrhizae with various levels of phosphorus (20 and 40 kg/ha) application on leghaemoglobin content as well as enzyme activity (nitrate, nitrite reductase) in nodules of common bean (Phaseolus vulgaris L.) during kharif seasons of 2012 and 2013 at the Krishi Vigyan Kendra (KVK) of Shere-e-Kashmir University of Agricultural Sciences and Technology, Budgam, Jammu and Kashmir. The experiment was laid out in a complete randomized block design (RBD). Rhizobium with AM @ 20 kg P/ha showed best significant impact in all parameters.
