| Abstract: | In order to investigate the influence of different sowing dates on main agronomic traits, yield and stem juices composition of trial sweet sorghum varieties, the variety-Liaotian No1 and No3 were planted in Nanning area. The results showed that the stem yield(4 329.11 kg/667.7 m2, 5 340.28 kg/667.7 m2)and juice Brix(21.18%, 18.27%)of the two sweet sorghum varieties cultivated at the end of April were the highest in all sowing dates. So this period is the best cultivation of two varieties. The two varieties, sown in March to August, had good performance in the stem yield, grain yield and juice Brix. And during this period, the two varieties were suitable for planting in Nanning area. |
