Integrated Nutrient Management for Growth and High Yield in Coleus Forskohlii.

Coleus forskohlii L. is an important medicinal plant species found in tropical regions of India. Roots and tubers are used for treating a variety of purposes, including treating asthma, bronchitis, insomnia, epilepsy and angina.Due to diverse use, the species has been largely exploited from natural habitat leading to its threatened status. A field experiment was conducted to study the influence of organic and inorganic fertilizers on its growth and yield. Six treatments including T1 Control -No Manures; T2: 100% NPK recommended dose (N- 40 kg ha-1), T3: 50% NPK + 10 Tonnes of Farm Yard Manure / ha-1, T4: 50% NPK + 5 Tonnes of Vermicompost/ ha, T5:20 Tonnes of Farm Yard Manure / ha and T6: Vermicompost 10 Tonnes/ha-1. Results indicated the improvement in the growth and yield. Combination of organic and inorganic fertilizers is very productive than the application of manures or fertilizers alone for achieving higher growth and yield in C.forskohli.
