Abstract: The study was conducted to evaluate the effect of barley varieties and precision nutrient management practices on growth, quality and yield at Udaipur (Rajasthan) during Rabi 2014-15 and 2015-16. The experiment was consisted 15 treatment combinations, comprising of three varieties (RD 2035, RD 2552 and RD 2786) and five precision nutrient management practices. On pooled basis, varieties RD 2552 and RD 2035 recorded significantly higher net assimilation rate over RD 2786 during 2014-15. During both the years, days to 50 per cent heading and maturity were 8 and 2 days earlier in the variety RD 2035 as compared to RD 2786 and RD 2552. The pooled results showed 10.64 and 4.83 per cent increased grain yield in variety RD 2552 over RD 2035 and RD 2786, respectively. Application of 70 per cent of recommended N and full P₂O₅ and K₂O as basal + Green Seeker based N top dressing (PNMP₄) and STCR based nutrient management (PNMP₅) significantly improve chlorophyll content at 30 and 60 DAS, protein content in grain. on pooled basis STCR based nutrient management (PNMP₅) recorded 23.33, 16.20 and 10.66 per cent higher grain yield over RDF- half N, full P₂O₅ and K₂O as basal + remaining half N before first irrigation (PNMP₂), RDF- half N, full P₂O₅ and K₂O as basal + remaining half N before first irrigation (PNMP₁) and 50 per cent of recommended N, full P₂O₅ and K₂O as basal + Green Seeker based N top dressing (PNMP₃), respectively.
