Abstract

Nitrogen at different levels and biofertilizers effects were studied on growth and yield of Barley. An experiment was conducted in a factorial randomized block design with three replications. Treatments included 3 levels of nitrogen (40, 60 and 80 kg ha-1) and bio-fertilizers on four levels (not inoculation, Azotobacter, Azospirillum and Azotobacter + Azospirillum). The results revealed that fertilizer --N @ 80 kg/ha with both (Azotobacter + Azospirillum) inoculations was found to be the most responsive, with significantly increased in the growth parameters viz plant height, maximum number of tillers and grain yield of barley. Azospirillum inoculation, Azotobacter inoculation and uninoculated control significantly differed between each other.
