| Abstract: | Experiment conducted with nine rice varieties during Pishanum season of 1989–90 revealed that Co 37 performed better in ratoon crop and recorded 3.2 t/ha grain yield. It was evident that the ratooning ability was influenced by stem thickness of stubble, carbohydrate content and leaf senescence of main crop. The study also suggests that by maintaining higher seed size and productive tiller in ratoon crop, there is ample possibilities to increase grain yield. |
