The field experiment entitled “Response of Nitrogen and Foliar Application of Boron on Growth and Yield of Barley (Hordeum vulgare L.)” was conducted Response of during the rabi season of 2022 in Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.). The experiment was laid out in a Randomized Block Design with ten treatment combinations. The soil in the experimental area was sandy loam with pH (7.6), EC (0.305 d S/m), organic carbon (0.23%), available N (184.8 kg/ha), available P (16.45 kg/ha) and available K (187.64 kg/ha). Seeds are sown at a spacing of 23 cm × 5 cm to a seed rate of 100 kg/ha. Consisting of three nitrogen levels (45, 60 and 75 kg N/ha) on different Concentration of Boron viz., 1, 1.5 and 3% foliar spray. The experimental result reveals that growth parameters viz., plant height (102 cm), number of tillers/running row meter (95.66), plant dry weight (19.08 g) and Yield attributes viz., No. of effective tillers/m² (200.33), number of grains/spike (52.60), seed yield (4.81 t/ha) and straw yield (6.48 t/ha) recorded to be significantly higher with treatment 9 (75 kg N/ha + 3% Boron).
