Description Studies on the “Effect of organic and bionutrition on growth, yield and quality in Ashwagandha (Withania somnifera Dunal.)” was conducted at College of Horticulture, Venkataramannagudem, West Godavari district of Andhra Pradesh during 2010-2011. The studies were carried out using ashwagandha cv. Poshita with 14 treatments viz., neem cake 4 t ha-1 (NC 4 t ha-1: T1), vermicompost 5 t ha-1(VC 5 t ha-1: T2), poultry manure 5 t ha-1 (PM 5 t ha-1: T3), farm yard manure 12 t ha-1 (FYM 12 t ha-1 : T4), insitu green manuring with sunnhemp (GM : T5), NC 4 t ha-1 + BF (T6), VC 5 t ha-1 + BF (T7), PM 5 t ha-1 + BF (T8), FYM 12 t ha-1 + BF (T9), GM + BF (T10), bio-fertilizers consisting of Azospirillum and Phosphate solubilizing bacteria (BF: T11), recommended dose of fertilizers (RDF : T12), 50 per cent recommended dose of fertilizers (50 per cent RDF : T13) and control (T14). The experiment was laid out in a randomized block design with three replications.
Among the different treatments, PM 5 t ha-1 + BF, VC 5 t ha-1 + BF and RDF had recorded higher growth attributes viz., plant height, number of branches per plant, leaf area, LAI, dry matter production and AGR for plant height on par with each other and significantly higher than other treatments at all the growth stages studied except 30 DAS. The other yield attributes and yield viz., root length, root diameter, fresh root yield, dry root yield and seed yields recorded with PM 5 t ha-1 + BF, VC 5 t ha-1 + BF and RDF were also on par with each other and significantly superior to other treatments indicating the potentiality of these treatments in enhancing ashwagandha root and seed yields.
The total alkaloid per cent recorded in ashwagandha root with the treatments, PM 5 t ha-1 + BF, VC 5 t ha-1 + BF and RDF was significantly higher over other treatments at harvest indicating the superiority of these treatments in enhancing the quality of produce. Among the treatments, application of PM 5 t ha-1 + BF, VC 5 t ha-1 + BF and RDF resulted in higher N P K uptake over other treatments in the experiment.
Among the different treatments, PM 5 t ha-1 + BF had recorded the highest gross income mainly on account of higher root and seed yield. The net income was, also, highest with PM 5 t ha-1 + BF owing to lower cost of cultivation and fair gross income. Further, the treatment, RDF recorded the highest BCR primarily on account of lower cost of cultivation and fair net income.
The treatments, PM 5 t ha-1 + BF and VC 5 t ha-1 + BF had recorded the growth, yield and quality attributes on par with RDF offering the scope for complete substitution of inorganic fertilizers with economic advantage over the other treatments with organic nutrient sources. Application of bio-fertilizers containing Azospirillum and PSB had resulted in growth, yield and quality attributes and nutrient uptake on par with 50 percent RDF offering the scope for reduction in inorganic fertilizers with increased soil health.
The present study clearly indicated that PM 5 t ha-1 + BF, VC 5 t ha-1 + BF and RDF were superior to other treatments in respect of root yield and quality with overall better performance. However, the treatment, PM 5 t ha-1 + BF with more economic advantage over can be recommended for obtaining higher yields in ashwagandha. Further for complete substitution of inorganic fertilizers, the treatment, PM 5 t ha-1 + BF can be recommended.
