Effect of Row Spacing and Organic Manures on Growth and Yield of Barley (Hordeum vulgare L.)

Abstract

A field experiment was carried out at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P) in Rabi 2021-2022 to study the “Effect of Row spacing and Organic manures on Growth and Yield of Barley (Hordeum vulgare L.)”. It was consisting of three combinations of Row spacing & Organic manures. The experiment laid out in Randomized Block Design which consisting of nine treatments with 18 cm+ FYM 5 tons/ ha,18 cm + Neem cake 0.8 t, 18 cm + Vermicompost 2 t, 20 cm + FYM 5 tons ha, 20 cm + Neem cake 0.8 t., 20 cm + Vermicompost 2 t,22.5 cm+ FYM 5 tons /ha ,22.5 cm+ Neem cake 0.8 t, 22.5 cm + Vermicompost 2 t. The experiment results revealed that the growth parameters and yield parameters such as plant height (79.74 cm), dry weight (19.77 g/plant), number of Tillers/m2 (449.40), number of grains/spike (25.33) and test weight (51.33 g) at harvest, significantly recorded in treatment 8 with the application of 22.5 cm+ Neem cake 0.8 t. Moreover, grain yield (5.22 t/ha), straw yield (7.95 t/ha) and harvest index (45.28%), were also recorded significantly higher in the treatment of 8 which is 22.5 cm + Neem cake 0.8 t/ha among all treatments. The row spacing along with basal application of organic manures could be a promising option for growth and yield enhancement in barley.
