Abstract: Plant growth promoting rhizobacteria (PGPR) are used for seed inoculation. This study was carried out to determine the influence of seed inoculation with PGPR and different nitrogen (N) and phosphorus (P) levels on the productivity and quality of fodder sorghum. The study was conducted in randomized complete block design (RCBD) under factorial arrangement at Agronomic Research Area, University of Agriculture, Faisalabad during, 2014. The experiment composed of N and P levels such as 0%, 50%, 75% and 100% of recommended doses ha-1 and seed inoculation with PGPR1 (Azotobacter brasilense+Pseudomonas fluorescens) and PGPR2 (Azotobacter chroococcum+Pseudomonas flurescens) with un-inoculated seeds as control. The results revealed that application of N and P, and seed inoculation appreciably increased the productivity and quality of sorghum. Maximum green fodder yield (63.12 t ha-1), dry matter yield (14.51 t ha-1), crude protein (11.02%) and ash contents (8.97%) were recorded with recommended dose of NP. Regarding seed inoculation maximum green fodder yield (62.40 t ha-1), dry matter yield (14.09 t ha-1), crude protein (10.59%) and ash contents (9.07%) were recorded with PGPR1. In conclusion, application of recommended dose of NP and seed inoculation with PGPR1 significantly improved the forage productivity and quality of sorghum.
