Effect of spacing and FYM on growth and yield of sweet flag (Acorus calamus L.)

Abstract

Sweet flag (Acorus calamus Linn.) that belongs to family Araceae, is an importantmedicinal and aromatic plant. The field experiment for three consecutive years with 9 treatments, three levels of spacing viz., S1 – 60 x 30cm, S2 – 60 x 45 cm and S3 – 60 x 60 cm and three levels of farm yard manure viz., F1– FYM 5 t/ha, F2– FYM 10 t/ha and F3 – 15 t/ha was laid in factorial randomized block design with three replications. The results of the experiment indicated that the application of FYM 15 t/ha in combination with plants at a spacing of 60 x 30 cm recorded significantly higher growth and yield compared to other treatments.
