Studies on Nutrient Content, Herbage Yield and Alkaloid Content of Kalmegh under Integrated Nutrient Management System

摘要

Kalmegh is an excellent medicinal plant with multiclinical properties. To study the effect of integrated nutrient management in Kalmegh, seventeen combinations of organic, inorganic nutrients and biofertilizers were experimented at the HorticulturalCollege and Research Institute, Periyakulam, Theni District, Tamil Nadu during 2003-2004. The study revealed that application of 15 t FYM ha(-1) + 45: 2.5 : 25 kg NPK ha(-1). + 1 kg Azospirillum ha(-1) resulted in maximum nutrient content in leaf tissues, herbage yield and andrographolide content of Kalmegh.
