Effect of rhizobia inoculation and phosphorus levels on symbiotic parameters, growth and yield of french-bean Phaseolus vulgaris L in North West Himalyan acid alasol*
Abstract
A field experiment consisting of four rhizobia strains (uninoculated, indigenous, indigenous marker and exotic) and four levels of P (0, 50, 100 and 150 kg P2O5 ha−1) was conducted on a northwest Himalayan acid alfisol using French bean (Phaseolus vulgaris L.) Kharif (summer) crop during 2000. Location specific indigenous strain performed better for symbiotic parameters, vis-a-vis, green pod and dry matter yield. 1be effect of phosphorus fertilization was discernible upto 100 kg P2O5 ha−1. The treatment combination indigenous strain of Rhizobium leguminosarum phaseoli with 100 kg P2O5 ha−1 gave the highest green pod yield and no inoculation with no phosphotus application gave the lowest green pod yield.
