Effect of severity of tiller removal on retillering and yieldability of rice
1989
Roy, S.K. | Biswas, P.K. | Quasem, A.
In a replicated field experiment 45 day old seedlings of rice variety BR 11 were transplanted and 0, 1, 3, 5 and 7 tillers were detached from the main hill at 35th day of transplanting in order to determine the retillering and yieldability of the tiller-severed main crop. The results show that the more severely the tillers removed the more the new tillers produced. Removal of 1 to 3 tillers hill-1 did not reduce the grain yield as compared to the no tiller removal (control) which produced 6.73t ha-1. But removal of 5 to 7 tillers-1 caused 14 to 22% reduction in grain yield which was mainly due to 8 to 14% reduction in the number of panicles m-2 and 5 to 8% reduction in the number of filled grain panicle-1.
