Abstract: The relation between N applying for bud development(NABD) at different days after full heading of main crop and the ratooning ability in hybrid mid rice was studied with the hybrid K-You 5. The results are as follows:the effect of the NABD appears around 10 days after full heading of main crop; From full heading to harvest of main crop, highly significant negative correlation is observed between ratooning ablitity and the days from NABD date to the full heading of main crop; Effect of date for the NABD on grain yield increase of ratooning rice is related to the dry weight of the basic stems, the effect is little when the dry weight of the basic stems is very high or low.
