Saved labor cost, energy conservation, reduced soil erosion, and increase of emergence rate would be expected from no-tillage cultivation of corn. Few research has been reported on the no󰠏tillage effects for waxy corn hybrid. Five waxy corn hybrids were tested under conventional and no󰠏tillage practices to investigate responses of early growth, plant characters, ear characters, fresh yield, and grain yield. Emergence rates under no󰠏tillage were lower than under conventional tillage. Plant heights at early growth stages under no󰠏tillage were higher than those under conventional tillage. Plant height under no󰠏tillage was higher than that under conventional tillage. There were no differences between conventional tillage and no󰠏tillage for ear length, number of kernel rows, number of kernels per row, 100 kernels weight, fresh yield, and grain yield. This result indicates that no󰠏tillage practice might be recommended for practical method for waxy corn production. Days to tasseling and silking, plant height, ear height, ear length, and number of kernels per row were correlated with fresh and grain yields.
