  1. Mgdw = Mega gram of rice straw in dry weight;HRR = Head rice recovery; CSRm = Complete straw removed; PSRm = Partial straw removed; SB = Straw burned; SRt = Straw retained.
  2. The standard error of the mean is displayed in parentheses.
  3. In a column, numbers followed by same letters are not significantly different by F-test Two-Sample for Variance at 0.05 level.
