 ABSTRACT

The experiment was conducted during Rabi 2015-16 and 2016-17 at Research Area of Agonomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana (India) situated at 29°10' N latitude and 75° 46' E longitude at an elevation of 215.2 m above mean sea level to notice the effect of fertilizer levels and different combinations of biofertilizers on potassium content & uptake and nutrient status of soil. 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. There was no significant influence of various fertilizer levels on K content in grain and straw of barley. Whereas significant effect was observed during both the years of experimentation on K uptake by grain and straw. Significantly higher K uptake by grain and straw were recorded with the application of 100 % RDF than rest two treatments. Seed inoculation with biomix recorded significantly higher K uptake by grain of barley as compared to rest of the treatments during both the years of experimentation. Nutrient content of soil did not differ significantly before planting of barley crop during both the years of experimentation. There was also no significant difference resulted due to application of different fertility levels and different combinations of biofertilizers on N, P, K status of soil after harvesting of crop during both the years of experimentation.

Key words: Fertilizer levels, Biofertilizers, Biomix, Nutrient content and K uptake
