MORPHOLOGY AND PHYSIOLOGY OF RATOON <strong>RICE</strong> 39Practices at or just before harvest also affect ratooning. The main crop shouldbe harvested before full maturity, delay reduces ratoon yields. Cutting heightdetermines the origin of the tillers and the growth duration of the ratoon crop.REFERENCES CITED1.
