| Abstract: | Most of the 39 maize super-high yield plots emerged in 2006 - 2007 were located in the high elevation regions(40°N - 43°N) which were characterized by abundant sunlight and large temperature difference between day and night. In order to achieve the yield level of 15 000 kg/ha, the suitable yield components of super-high yield plots would be 79 725 - 84 630 ears/ha, 560 - 588 kernels per ear, the 1 000-kernel weight and the total kernel weight per ear would be 347 - 359g, 200 g, respectively. The corresponding cultural practices included the selection of suitable planting regions and superior varieties, reasonably dense planting, scientific fertilizer application and timely irrigation. |
