| Abstract: | The main factors of yield per unit increasing were analyzed by using the data of corn yield from 1949 to 2005 in this paper. The estimation of yield potential shows that there is still a large potential for the increase of corn yield per unit in China. Based on experts' assessment, the main constraints for the realization of corn yield potential and suggestions on increasing corn yield per unit are put forward. |
