摘要

Energy cane is believed to have more vigor than sugar cane because energy cane contains a higher percentage of alleles from m>Saccharum spontaneumm> relative to m>Saccharum officinarumm>. Cane, sucrose, and fiber yields of three sugar cane varieties (HoCP 96-540, L 99-233, and L聽99-226) and one energy cane variety (L 79-1002) were compared when planted on August 1, September 1, and October 1. Varieties responded similarly (m>Pm>聽=聽0.08) to planting date. Averaged across varieties in plant cane, the August planting date produced 11.6 and 18.1聽Mg聽ha^鈭? more sugar cane and 1600 and 2300聽kg聽ha^鈭? more sucrose than the September and October plantings, respectively. The August planting increased fiber yields by 2.4聽Mg聽ha^鈭? relative to the average of the September and October planting dates. Moreover, the September planting date produced 6.5聽Mg聽ha^鈭? more sugar cane and 700聽kg聽ha^鈭? more sucrose than the October planting date, but there were no differences between the fiber yields for the September and October planting dates. Our data suggest that growers should attempt to plant both sugar and energy cane in August to maximize yields. However, if plantings are delayed into September for both sugar and energy cane, it is best to plant sugar cane first, instead of energy cane, because sucrose yield continued to decline in October while fiber yields were consistent with September and October plantings.
