Abstract
Flemingia semialata W. T. Aiton has emerged one of the most suitable lac host plant which is bushy in nature and quick growing, and more importantly lac cultivation can be started from second year on commercial basis. Application of balanced quantity of nutrient is one of the key factor to ensure healthy growth and maintain the nutrient balance of soil and to obtain higher lac yield of Flemingia.
A field experiment was carried out at Agriculture Research Station, Malagi, Uttara Kannada district during 2015-16 on “Integrated Nutrient Management in Flemingia semialata W.T. Aiton Plantation”. The experiment was conducted in randomized complete block design with ten treatments and three replications. Among the different treatments tried combine application of farm yard manure (2 kg/plant) + 175:100:50 NPK kg/ha has recorded significantly maximum plant height (221.13 cm), collar diameter (22.08 mm), number of shoots,(11.93), number of infected shoots,(11.93), length of infected shoots (112.01 cm), lac yield (2273.33 kg/ha), Soil moisture content (15.47 %), available soil nitrogen (195.0 kg/ha), available soil phosphorous (54.63 kg/ha) and available soil potassium (105.3 kg/ha) compare to other treatments. The results were attributed due to the application of optimum levels of organic manure and varied nitrogen levels. The results suggested that NPK @175:100:50 kg/ha with combination of FYM @ 2 kg/plant recorded higher growth parameters, yield parameters as well as maximum lac yield. Application of (FYM 2 kg/plant) + 175:100:50 NPK kg/ha also recorded on par lac yield.
