Glucoside content and its accumulation in bach (Acorus calamus LINN.) as influenced by nitrogen and phosphorus application

An experiment was conducted during 1999-2000 and 2000-2001 to assess the effects of different levels of nitrogen and phosphorus on total glucoside accumulation in rhizomes and roots of bach (Acorus calamus Linn.). Results revealed that application of nitrogen and phosphorus @ 150 kg/ha each led to maximum glucoside accumulation in rhizomes (3.29%) and roots (5.19%), which was higher by 225% and 192%, respectively compared to control. Glucoside accumulation was more in roots as compared to rhizomes with increase in nitrogen and phosphorus doses.
