A field experiment entitled “Effect of nutrient management and crop geometry in sweet flag (Acorus calamus)” was carried out at Instructional-cum-Research farm, Assam Agricultural University, Jorhat during 2012-2013 in randomized block design (RBD) with three replications to assess the effect of different crop geometry and application of different organic and inorganic fertilizers on plant growth and development and yield attributing characters for commercial production. The results revealed that wider crop spacing (30 cm × 30 cm) has significantly higher growth i.e., plant height and dry matter and yield attributing characters i.e., rhizome weight, size of rhizome (length and girth) and number of plants/clump than close spacing. However, closer spacing recorded significantly higher yield (rhizome and oil) and N, P, K uptake as well as higher gross return (Rs.107583.00), net return (Rs.63879.00) and benefit: cost ratio (1.45) than wider spacing. Application of 20-10-15 N-P2O2-K2O kg/ha + Vermicompost @ 1 t/ha being at par with 60-30-45 N-P2O2-K2O kg/ha recorded significantly higher growth, yield attributes, yield and N, P, K uptake of Acorus calamus. Application of 20-10-15 N-P2O2-K2O kg/ha + Vermicompost @ 1 t/ha recorded the highest gross return (Rs.104500.00) followed by 60-30-45 N-P2O2-K2O kg/ha. However 60-30-45 N-P2O2-K2O kg/ha recorded the highest net return (Rs.65911.00) followed by 20-10-15 N-P2O2-K2O kg/ha + Vermicompost @ 1 t/ha (Rs. 60617.00).
