Abstract:
Forage sorghum [Sorghum bicolor (L.) Moench] is a warm-season annual grass used mainly as a silage or hay crop in the USA with the potential to become a bioenergy feedstock. Chilling-tolerant forage sorghum genotypes would allow an earlier planting for more optimum use of the growing season. This will likely lead to an increase in productivity of forage sorghum in North Central Regions of the USA. The objective of this study was to screen and select potential chilling-tolerant forage sorghum genotypes with the hypothesis that chilling-tolerant genotypes would produce greater or similar dry matter yield when sown earlier than normal into field plots in Fargo and Hickson, ND. In the field, cv. SPX-901 was among the highest yielding genotypes (16.4 Mg ha-1), which produced similar yields between early (10 May) and more normal (27 May) sowing dates. These results indicate that early planting did not affect crop performance and yield. Preliminary conclusions indicate chilling tolerance exists among commercial cultivars, which can produce greater biomass yield when planted earlier than normal in the North Central US.
