Abstract
A field investigation to know the effect of spacing and time of harvest on nutrient uptake in medicinal coleus was conducted at Kittur Rani Channamma College of Horticulture, Arabhavi during Kharif 2004 and 2005. Closer spacing of 60 cm x 20 cm recorded significantly higher nutrient uptake (21.6, 2.6 and 25.3 kg / ha of N, P and K, respectively) in tubers. Higher uptake of N, P and K at 160 (18.8, 2.2 and 21.7 kg / ha, respectively) and 180 DAP (17.9, 2.2 and 20.7 kg / ha, respectively) was recorded in tubers. Spacing and time of harvest did not influence the total uptake of nutrients. Higher uptake of NPK (102.1, 11.2 and 117.1 kg / ha, respectively) was recorded at 140 DAP in top portion.
