Abstract: Two field experiments were conducted during late kharif seasons of 2004-05 to 2005- 06 on vertisols of Agricultural Research Station, Annigeri, University of Agricultural Sciences, Dharwad to study the effect of date of sowing, stage of harvesting, spacings and fertilizer levels on ashwagandha. The crop sown on September 15th and harvested at 180 DAS recorded significantly higher root yield (1622 kg ha-1), root length (41.3 cm), root diameter (1.05 cm), fresh root weight (8.295 g plant-1), dry root weight (2.712 g plant-1), total dry matter production (21.543 g plant-1) and dry matter accumulation in roots of ashwagandha (2.712 gplant-1) compared to other treatment combinations. Significantly higher total withanolide content (0.620%) in roots of ashwagandha and total withanolide yield (10.059 kg ha-1) were recorded by the crop sown on September 15th and harvested at 180 DAS. The crop sown on September 15th and harvested at 180 DAS realized significantly higher net returns (Rs. 54,880 ha-1) and B:C ratio (6.49) compared to other treatment combinations. The root yield of ashwagandha was significantly higher (1543 kg/ha) with plant geometry of 15 cm x 10 cm supplied with 24:48 kg N and P2O5 per ha compared to others and was on par with 15 cm x 10 cm with 18 : 36 kg N and P2O5 per ha (1528 kg ha-1). The treatment combination of 15 cm x 10 cm with 24:48 kg N and P2O5 per ha recorded significantly higher uptake of N (24.1 kg ha-1), P (2.72 kg ha-1), K (39.5 kg ha-1) by roots, total withanolide content (0.620%) in roots and total withanolide yield (9.559 kg/ha) of ashwagandha compared to others and was on par with that of 15 cm x 10 cm spacing along with 18 : 36 kg N and P2O5 per ha. The plant geometry of 15 cm x 10 cm supplied with 24:48 kg N and P2O5 per ha realized significantly higher net returns (Rs. 51,747 ha-1) compared to others and was on par with 15 cm x 10 cm with 18 : 36 kg N and P2O5 per ha.
