Abstract:
The research work entitled “Effect of different nutrient management practices on growth and yield of ashwagandha (Withania somnifera L.)” was carried out in Rabi season of 2021-22 under the Department of Agronomy, College of Agriculture, IGKV, Raipur, (C.G.) The main objective was to analyze the effect of different nutrient management combinations in treatments on growth and yield of ashwagandha crop. There were total ten treatments, comprises of T₁: 100% RDN (60:40:40 N:P₂O₅:K₂O kg ha^-1), T₂: 100% RDN + 5t FYM ha^-1, T₃: 100% RDN + 1.0 t vermicompost ha^-1, T₄: 100% RDN + Foliar spray (NPK 19:19:19 at 0.5%), T₅:75% RDN + 5t FYM ha^-1, T₆ :50% RDN + 5t FYM ha^-1, T₇:75% RDN + Foliar spray (NPK 19:19:19 at 0.5%), T₈:50% RDN + Foliar spray (NPK 19:19:19 at 0.5%), T₉: 10 t FYM ha^-1 and T₁₀: 100% RDN through organic sources (1/3^rd FYM + 1/3^rd Vermicompost + 1/3^rd Neem cake). The experiment revealed that the application of 100% RDN + 5t FYM ha^-1 significantly increased the plant growth parameters such as plant height, number of branches plant^-1 and number of leaves plant^-1. Significantly higher yield attributes such as number berries plant^-1 (148.3), number of seeds berry^-1 (44.33), 1000 seed weight (2.39), seed yield ha^-1 (103.62 kg ha^-1), root yield ha^-1 (522.2 kg ha^-1) and straw yield ha^-1 (852.15 kg ha^-1) was also recorded with the application of the 100% RDN + 5t FYM ha^-1 during the course of investigation.
