Straw management by incorporation into the soils is an alternative method to avoid straw burning before land preparation.The experiment was conducted at Pathum Thani Rice Research Center and Suphan Buri Rice Research Center during 2006-2007. It was comprised of 3 trials, i.e., effect of amount of straw incorporated into soils to rice growth and yield, effect of straw management methods to rice growth and yield, and effect of straw incorporation period to rice growth and yield. The results showed that straw incorporation rate of 0-800 kg/rai did not affect early growth stage (number of plants/m2 at 15 days after planting) and yield. Number of plants/m2 at 15 days after planting was decreased by straw incorporation at the rate of 1,200-1,600 kg/rai whereas... |
