Rhizome Yield of Sweet Flag Acorus calamus L as Influenced by Planting Season, Harvest Time, and Spacing



Rhizome Yield of Sweet Flag Acorus calamus L as Influenced by Planting Season, Harvest Time, and Spacing



International Journal of Agronomy 2012: 1-8



A study was undertaken for two consecutive years to assess the possibility of optimizing rhizome yield of Acorus calamus L. (sweet flag) by shifting the time of planting (i.e., growing in rainy and autumn seasons), maintaining different spacings, and harvesting in different months. Significantly higher yields of A. calamus were recorded when seeded in autumn (13150?kg?ha?1) than rainy (6570?kg?ha?1) season. Harvesting of crop after 12 months gave maximum rhizome yields of 16470?kg?ha?1 and 9370?kg?ha?1 respectively during autumn and rainy seasons. A similar trend was also noticed in various yield components (i.e., length, width and weight of rhizome). Closer planting (20 20?cm, 30 20?cm) gave significantly higher rhizome yield (8620?kg?ha?1, 8120?kg?ha?1) than wider spacing 40 40?cm (7030?kg?ha?1). This study illustrated the possibility of optimizing rhizome yield of A. calamus by manipulation in the time of planting and harvesting as well as maintaining proper plant spacing.
