Abstract
Investigations on integrated nutrient management studies in
coleus were carried out during kharif season of 2006 and 2007 at
Department of Medicinal and Aromatic Plants, Kittur Rani Channamma
College of Horticulture, Arabhavi located under Western dry zone of
Karnataka. In the first experiment, combined application of RD FYM +
RD NPK + neem cake + AZT + AZP (T16) recorded significantly higher
values for growth parameters, number of tuberous roots per plant
(16.43), length of tuberous roots (11.70 cm), girth of tuberous roots (1.71
cm), fresh and dry weight of tuberous roots per plant (211.17 g and
35.00 g, respectively) and per hectare (8.51 t and 1.41 t, respectively),
forskolin content (0.62%), maximum total uptake of nitrogen (123.79
kg/ha), phosphorus (58.93 kg/ha) and potassium (163.90 kg/ha), net
income (Rs. 22,964.50) and cost : benefit ratio (1 : 1.48).
In the second experiment, plants provided with RD NPK + RD FYM
+ AZT + PSB + VAM (T11) recorded significantly higher values for growth
parameters, number of tuberous roots per plant (12.57), length of
tuberous roots (12.26 cm), girth of tuberous roots (1.64 cm), fresh and
dry weight of tuberous roots per plant (277.50 g and 39.39 g,
respectively) and per hectare (11.27 t and 1.60 t), forskolin content
(0.76%), highest nitrogen (115.83 kg/ha), phosphorus (49.59 kg/ha) and
potassium (151.55 kg/ha) uptake, maximum net income (Rs. 39,064.50)
and cost : benefit ratio (1 : 1.95).
Thus, based on the growth, yield, quality and C : B ratio, it could
be inferred that application of RD NPK + RD FYM + AZT + PSB + VAM
can be adopted by the coleus growers in the western dry zone of
Karnataka.
