Effect of integrated nutrient management on performance, productivity and economic feasibility of barley (Hordeum vulgare L.) in Easter Uttar Pradesh

Abstract

An experiment was carried out at Crop Research Farm of National Post Graduate College, Barhalganj, Gorakhpur, (U P.) During Rabi season on (2022-2023) the soil of the experimental field was silty loam in texture with low, medium and high in N, P and K respectively. The experimental site is situated in subtropical zone in indo gangetic planes. The experiment was laid out in Randomized Block Design with 8 treatment combinations and 3 replications. Barley was shown on 3rd December 2022 with treatment combinations viz T1 Control, T2 50% RD of NPK (50-30-30) kg, T3 75% RD of NPK (75-45-45) kg, T4 100% RD of NPK (100-60-60) kg, T5 50% RD of NPK + (20 kg ZnSO4), T6 50% RD of NPK + 5 tons FYM + (20 kg ZnSo4), T7 75% NPK + 5 tons FYM + (20 kg ZnSo4), T8 100% NPK+ 5 tons FYM + (20 kg ZnSo4). The crop was harvested on 5th April 2023. The result indicated that the treatment combination T7 75% NPK + 5t FYM + (20 kg ZnSo4) was registered significantly superior in terms of plant height, number of tillers, dry weight(gm), test weight(gm), Harvest index(%), grain yield(q ha-1), straw yield(q ha-1), gross return (Rs/ ha) and net return (Rs / ha.), respectively over rest of the treatments. Integrated use of organic manures along with optimum doses of chemical fertilizers increased the growth parameters and yield of Barley.
