Abstract
An investigation on “Effect of organic and inorganic source of nutrients on growth, yield and quality of ashwagandha (Withania somnifera Dunal)” var. Poshita was conducted in the Department of Plantation, Spices, Medicinal and Aromatic Crops, Kittur Rani Channamma College of Horticulture, Arabhavi, during 2014-15.
At harvest (150 DAS), the treatment T3 (40:50:40 NPK kg/ha through inorganic fertilizers + 5 t/ha FYM) recorded maximum plant height, number of leaves, E-W plant spread, leaf area, leaf area index, dry matter production, fresh root yield/ha (20.92 q), dry root yield/ha (7.36 q), root length, root diameter, alkaloid content (0.25 %), EC, nitrogen uptake by leaf, stem, berries, potassium uptake by stem, highest gross return (1,54,331 Rs/ha) and net return (1,20,977 Rs/ha). Plants supplied with 20:25:20 NPK kg/ha through inorganic fertilizers recorded maximum number of berries per node and seed yield/ha. Maximum nitrogen and potassium status in soil after harvest and phosphorous uptake by stem was recorded in plants supplied with 40:50:40 NPK kg/ha 25% through FYM + 75% through inorganic fertilizers.
The treatment T6 (20:25:20 NPK kg/ha 50% through FYM + 50% through inorganic fertilizers) recorded maximum pH and phosphorous status in soil. Plants supplied with 30:37.5:30 NPK kg/ha through inorganic fertilizers recorded maximum potassium uptake by root and berries and maximum B:C (5.10). The plant supplied with 40:50:40 NPK kg/ha through FYM recorded maximum phosphorous and potassium uptake by leaf and maximum moisture content in soil. Maximum bacterial and actinomycetes count was recorded in soil supplied with 30:37.5:30 NPK kg/ha through FYM.
