Abstract: The present study entitled, “Effect of integrated nutrient management practices on LAI and quality parameters of barley” was conducted during the rabi season of 2017-2018 at the Agronomy Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar to study the effect of different nutrient management practices on quality parameters of barley. The soil of the experimental field is sandy loam in texture, slightly alkaline in reaction, low in organic carbon and nitrogen, medium in available phosphorus and potassium. The experiment was laid out in Randomized Block Design replicated thrice with ten different treatments viz. T1(Control) , T2 (Biomix) , T3 (Vermicompost @ 5 t ha-1), T4 ( Biomix + Vermicompost @ 5 t ha-1), T5 (50 % RDN + Vermicompost @ 5 t ha-1), T6 (75 % RDN + Vermicompost @ 5 t ha-1), T7 (50% RDN + Biomix + Vermicompost @ 5 t ha-1), T8 (75 % RDN + Biomix+ Vermicompost @ 5 t ha-1), T9 (RDN) and T10 (RDN + Biomix + Vermicompost @ 5 t ha-1). Among various combinations of nitrogen fertilizer, biomix and vermicompost leaf area index at 30 DAS was highest in treatment T10, being significantly higher than other treatments but statically at par with treatment T8 and T9. Similarly at 60 and 90 DAS the difference in leaf area index value of barley at in treatment T8, T9 and T10 were not significant but higher than other treatments. Treatment T10 (11.74 %) being at parwith treatment T3 to T9 resulted in significantly higher protein content of barley and treatment T1 being at par with treatment T2 recorded significantly higher value of malt content of barley than treatment T3to T10. But various combinations of nitrogen fertilizer, biomix and vermicompost fail to influence hectoliter weight and boldness as well as thinness of barley grain.
