The experiment was conducted at Research Area of Agonomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana (India) during Rabi season 2016-17 to notice the effect of fertilizer levels and different combinations of biofertilizers on Phosphorus content & uptake in 2016-17. Experiment was laid out in split plot design having various RDF levels (50%, 75% and 100%) and different combinations of biofertilizers (uninoculated, Azotobacter, Azospirillum, PSB, biomix, Azotobacter + PSB and Azospirillum + PSB) were used as treatments. Among different fertility levels, application of 100% RDF resulted in significantly higher P uptake in grain and straw of barley than rest two treatments (50 and 75 % RDF). Different combinations of biofertilizers fail to influence P content in grain and straw of barley crop. Least value for P content in grain was obtained from uninoculated treatment (0.41% in the year 2016-17).
