Abstract

Abstract: To explore the suitable varieties and density of Sorghum bicolor in central and southern Hebei province, the varieties Nongdahong 3, self selected Dwarf 1 and Hongmaoliang 6 selected by Hebei Agricultural University were used as experimental materials. The two factor complete random design was adopted, and three density treatments were set up to compare the three varieties. The results showed that the yield of Nongdahong 3 was significantly higher than that of other varieties; The planting density was 120 000 plants/hm², and the yield level was up to 10 270.50 kg/hm². Nongdahong 3 is suitable for planting in central and southern Hebei province. The suitable density of sorghum is about 120 000 plants/hm², which can achieve high yield.

Key words: Sorghum bicolor （L.） Moench, planting density, varieties, yield, agronomic characters
