Economics of Pashanbhedi (Coleus Forskohlii Briq.) as Influenced by Spacing, Time of Harvest and Their Interactions Under Irrigated Condition

Field experiment conducted during kharif seasons of 2004 and 2005 at Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka revealed that closer planting (60 cm x 20 cm) of pashanbhedi recorded significantly higher gross (Rs 82,083/ha) and net returns (Rs. 56,822/ha), and B: C ratio (3.25) than wider spacing levels (60 cm x 30 cm, 75 cm x 20 cm and 45 cm x 30 cm). Among the time of harvest, harvesting the crop at 180 and 160 DAP recorded significantly higher B: C ratio (3.17 and 3.07, respectively), and gross (Rs.76,188 and 73,438/ha, respectively) and net returns (Rs. 52,279 and 49,609/ha, respectively) than 140 DAP. The interaction effects showed higher B: C ratio in the treatment combination 60 cm x 20 cm – harvesting at 180 DAP (3.67) and 60 cm x 20 cm –harvesting at 160 DAP (3.62). Thus, the spacing of 60 cm x 20 cm and harvesting pashanbhedi at 160 DAP can be recommended for higher returns under irrigated condition.
