The experiment was carried out at Herbal garden, Rajendranagar, Hyderabad during the 2009-10. The experiment was laid out in Completely Randomized Block Design with factorial concept comprising a total of 18 treatments replicated thrice with two sowing dates (August 15^th and August 30^th), three seed rates (10 kg/ha, 12 kg/ha and 14 kg/ha) and three harvesting durations (150 DAS, 180 DAS and 210 DAS). Length of the root (29.43 cm) was longer with the crop sown on August 15^th when compared to August 30^th crop. Among the seed rates, S₁ (10 kg/ha) recorded maximum length of the root (28.49 cm). Among the harvesting durations, H₁ (150 DAS) recorded maximum length of the root (28.46 cm). The highest length of the root (31.63 cm) was recorded with August15^th sown crop with a seed rate of 12 kg/ha and harvesting duration of 210 DAS (D₁S₂H₃). Maximum thickness of the root (1.23 cm) was recorded with August 15^th sown crop when compared to August 30^th crop. Among the harvesting durations, H₃ (210 DAS) recorded maximum thickness of the root (1.18 cm). Among the three way interactions, maximum thickness of the root (1.32 cm) was recorded with August15^th sown with a seed rate of 12 kg/ha and harvesting duration of 210 DAS (D₁S₂H₃). Maximum fresh root yield (13.91 q/ha) and dry root yield (3.38 q/ha) was recorded in August 15^th sown crop when compared to August 30^th crop. Among the harvesting durations, H₃ (210 DAS) recorded maximum fresh root yield (13.48 q/ha) and dry root yield (3.12 q/ha). Among the three way interactions, maximum fresh root yield (15.63 q/ha) and dry root yield (4.40 q/ha) were recorded with August15^th sown crop with a seed rate of 12 kg/ha and harvesting duration of 210 DAS (D₁S₂H₃). Days taken for harvesting of seed (152.96 days) was early in August 15^th sown crop when compared to August 30^th crop. Among the interactions, early days taken for harvesting of seed (150.00 days) was recorded with August15^th sown crop with a seed rate of 12 kg/ha and harvesting duration of 180 DAS (D₁S₂H₂). Maximum total biomass production (1109.25 g/m²) was recorded in August 15^th sown crop when compared to August 30^th crop. Among the harvesting durations, H₃ (210 DAS) recorded maximum total biomass production (1079.39 g/m²). The highest total biomass production (1304.18 g/m²) was recorded with August15^th sown crop with a seed rate of 12 kg/ha and harvesting duration of 180 DAS (D₁S₂H₂).
