ABSTRACT

A field experiment was conducted during kharif, 2022 on sandy loam soils of S.V. Agricultural College Farm, Tirupati. The experiment was laid out in a split-plot design and replicated thrice. The treatments consisted of four varieties of barnyard milled viz., VL-172 (V₁), VL-207 (V₂), CO-2 (V₃) and VL-182 (V₄) assigned to main plots and three nitrogen levels viz., 20 kg N ha-1 (N₁), 40 kg N ha-1 (N₂) and 60 kg N ha-1 (N₃) allotted to sub plots. The results of the experiment indicated that among the varieties tested significantly higher grain yield, straw yield and nutrient uptake were obtained with the variety CO-2 (V₃), while the higher post-harvest soil nutrient status was with VL-182 (V₄). Among the nitrogen levels tried, application of 60 kg N ha-1 (N₃) resulted in significantly higher grain yield, straw yield, nutrient uptake and post-harvest soil available nitrogen status, while the highest post-harvest soil available phosphorus and potassium were with 20 kg N ha-1.
