Cultivar selection of silage maize in Chengdu

Nine domestic silage corn cultivars were used to compare the productivity due to the increasing growing area and lack of silage maize cultivars in Sichuan. The growth period, grass yield, plant height and growth rate were measured and the result indicated that Sicao NO.1 was the best in terms of yield, quality and adaptation. Jindan NO.2 was the best in terms of protein content and premature.
