| Abstract: | Three different maturity cultivars, premature Luyuandan 14 (LD14), medium mature Yedan 22 (YD22) and late mature Yedan 13 (YD13), were chosen to study the effects of different maturity maize cultivars relay-cropping in spring-sowing and summer-sowing on biomass, grain yield, and nutritive values of whole plant for feeding. The results indicated that relay-cropping with different mature summer-sowing maize cultivars, there were no obvious effects on biomass, grain yield, and nutritive values (crude protein yield, crude fiber yield, crude fat yield) of the same spring-sowing maize cultivars. But relay-cropping with different mature spring-sowing maize cultivars could obviously affect the biomass, grain yield, and nutritive values of the same summer-sowing maize cultivars. The order of biomass, grain yield, and nutritive values of the same summer-sowing maize cultivars was: relay-cropping with spring-sowing LD14> relay-cropping with spring-sowing YD22> relay-cropping with spring-sowing YD13. From the evaluation of grain yield of the whole year, YD22/YD13 was the highest treatment. But according to biomass, grain yield, and crude protein yield, crude fiber yield, crude fat yield of the whole year, the better ones were: YD13/YD13, YD13/YD22, and YD22/YD13. |
