Abstract


Abstract :The present study, effect of plant density and harvesting stage on shatavari was carried out during 2019-2021 at Kittur Rani Channamma College of Horticulture, Arabhavi. The results revealed that, maximum number of roots (209.10/plant), root volume (3346.66 cc), root length (37.64 cm), root girth (13.99 mm), higher fresh and dry root yield per plant (3.47 and 0.56 kg, respectively) and maximum fresh to dry root recovery (16.54 %) were recorded at wider spacing of 1.2 m × 1.5 m (D4 ). Maximum fresh and dry root yield per hectare (402.00 and 59.24 q, respectively) and total saponin content (6.06 %) were obtained at closer spacing of 1.2 m × 0.6 m (D1 ). Among harvesting stages, H4 (18 MAP) recorded more number of roots per plant (210.00), maximum root length (45.78 cm), root girth (14.87 mm), root volume (3712.50 cc), maximum fresh and dry root yield per hectare (359.73 and 55.20 q, respectively). D1H4 recorded maximum fresh and dry root yield per plot and per hectare and also higher gross returns (`7,58,250), net returns (` 4,43,038) and returns per rupee of investments (2.41)
