Abstract:

Lentil is one of the important legume crop widely grown in India. The availability of low phosphorous in soil is one the major concern for the production of legume crop in the country. Thus, the present study was aimed to evaluate the plant growth promoting efficiency of phosphate solubilizing Chryseobacterium sp. PSR 10 with different doses of inorganic fertilizers (N and P) on lentil growth and yield under field conditions. The phosphate solubilizing potential of this bacterial strain through In vitro tricalcium phosphate solubilization in NBRI-BPB broth medium was 210.43µgml-1. The field experiments were conducted for two “Rabi” crop seasons. To evaluate the potential of Chryseobacterium sp. PSR 10, lentil seeds were inoculated with the bacterium and applied with 30, 50 and 100% of recommended doses of nitrogen (N) and phosphorous (P) fertilizers along with unfertilized (without N and P) uninoculated control and fertilized (with N and P) but uninoculated control. Seed inoculation with 50% of recommended dose of nitrogen (N) and phosphorus (P) increased plant growth (agronomical parameters, chlorophyll content, nitrate reductase activity, phosphorus content and crop yield) significantly over control. Therefore, the study concluded that phosphate solubilizing plant growth-promoting bacterium Chryseobacterium sp. PSR10 broadens the spectrum of phosphate solubilizers available for field applications and might be used together with 50% dose of nitrogen and phosphorous.
