Some factors governing rice-ratoon yields

Summary Studies on rice ratooning showed that the height of cutting the main crop affected the maturity period and the yield of the ratoon. The ratoon yield was significantly higher when the main crop was cut at ground level versus cutting at 4,8 and 12 cm high, but the maturity period was lower with a higher cutting. Delaying first watering for 4 to 8 days was superior to watering a day after the harvest of the main crop. The ratoon yield was about 14 per cent higher than the planted crop.
