Nutritional management in Coleus (Coleus parviflorus Benth)

Abstract

An experiment was conducted at the College of Agriculture, Vellayani with the objective of finding out the optimum doses of nitrogen and potash tried were 0, 30, 60,90 and 120 kg/ha each. The two timings tried were entire dose as basal, and half basal and half thirty days after planting. Nitrogen had significant effect on plant height, number of branches, number of functional leaves, plant spread and leaf area index whereas levels of potash had not much effect on these aspects except at early stage. Time of application of nutrients had no effect on these growth characters.
