Abstract:
In order to find out performance of promising entries of oat under different nitrogen level, the present research work entitled “Influence of nitrogen levels on herbage yield and economic of promising entries of oat (Avena sativa L.) Under Chhattisgarh plains” was conducted during Rabi season of 2020-21 at Agriculture Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh). The soil was clay loam having neutral reaction (pH 7.0), low available soil nitrogen (150.52 kg ha^-1), medium available soil phosphorous (16.23 kg ha^-1) and high exchangeable soil potassium (364 kg ha^-1). The experiment consisted with ten promising entries of oat as a main plot treatment and three nitrogen levels viz. 60, 90 and 120 kg N ha^-1 as sub plot treatment was laid out in split plot design with three replications. The ten promising entries of oat were OL-1874-1, Kent, OL-1876-1, RO-11-1-3, JO-06-23, SKO-241, RO-11-1, OS-6, RO-11-1-2, and HFO-806. The crop was sown 20th November, 2020 with a seed rate of 100 kg ha-1 and harvested at 50% flowering. The crop was fertilized with 100:40:20 kg N: P2O5: K2O ha-^-1. The 60% nitrogen and whole quantity of phosphorous and potassium was applied as basal and remaining 40% N was given at 40 days after sowing. Among different promising entries of oat, OL-1874-1 gave the highest yield of herbage (448.9 q ha^-1), dry fodder (94.2 q ha-^-1) and per day productivity, gross return (Rs 67333 ha-^-1), net return (Rs 41234 ha^-1) and Benefit: Cost ratio (2.58). Among nitrogen levels, yield viz. herbage yield (345 q ha-1), dry fodder yield (76.27 q ha-1) and productivity (3.88 and 0.86 q ha-1 day-1), respectively and economic of gross return (Rs 51737 ha-1), net return (Rs 25227 ha-1) and Benefit: Cost ratio (1.95) increased with increasing levels of from application of 60 to 120 kg N ha-1.
