Abstract

The method of ratooning has differential effect on yield of FB-24. The ratoon crop produced by cutting the stalks to the ground level, three from the ground, and 10 centimeters from the ground gave significant yields at 0.01 level of significance over the ratoon crop produced by cutting the stalks above the last upper node (treatments d and e). The first three treatments, however, failed to produce statistically different yields between each other.

The yield of the ratoon crop was significantly lower at the 1 per cent level of significance than the yield of the principal crop regardless of the treatments. Since only the harvest was made of the crop, non-uniform maturity of the panicles of the plants in a hill proved to be the cause of low yield of the ratoon crop.

The length of cutting the rice stalks at harvesting appeared to have affected the number of days from harvesting the main crop to heading of the ratoon crop. Closer cutting of the stalk to the ground lengthened the number of days to heading.
