Abstract:The effects of different organic fertilizer application rates on the yield and quality of fruit corn were studied in this experiment. The results showed that the organic fertilizer increased steam diameter, total leaf number and dry matter of aboveground part, delayed the senescence of leaf, promoted the material accumulation in late stage. Therefore, the ear number per unit area, grains per ear and 1000-grain weight increased. The effect was enhanced with the increase of organic fertilizer application rate. The difference of fresh yield among all treatments was significant. The difference of 1000-grain weight under treatments of 15 t/hm2and 45 t/hm2was not significant, but the 1000-grain weight was significantly higher than the treatment of 0 t/hm2.The ear diameter and ear weight under the treatment of 45 t/hm2were significantly higher than the treatments of 0 t/hm2and 15 t/hm2. The content of soluble sugar, starch and protein in fruit corn seed under the treatment of 45 t/hm2were also significantly higher than the treatment of 0 t/hm2.The organic fertilizer can also improve the taste of fruit corn so that it can increase its commodity value.
