Effect of fertility levels on growth and yield of barley (Hordeum vulgare L.) varieties in central plain zone of Uttar Pradesh

A field experiment was conducted during rabi seasons of 2023-24 as carried out at agricultural farm of Rama University, Kanpur to find out effect of fertility levels on growth and yield of barley (Hordeum vulgare) varieties in central plain zone. The treatment comprised 9 combination of 3 varieties V₁-Haritma (K-560), V₂ -Narmada (K-603) and V₃-Lakhan (K-226) and 3 fertility level F₁ (N, P2O5& K2O)- 40;20;20, F₂ -60;30;30 & F₃- 80;40;40 tested in Split plot design (SPD). In which variety 'Haritma' (29.51 q/ha) and 'Narmada' (29.40 q/ha) being at par produced higher grain yield than 'Lakhan' (26.43 q/ha). Among fertility level, N-80, P-40, K-40 recorded significantly higher grain yield (31.22 q/ha) followed by N-60, P-30, K-30 (29.27 q/ha) and lowest yield recorded in N-40, P-20, K-20 (24.85 q/ha).
