The N fertilizer treatments (0, 45, 90 and 135 lb/A) were applied as urea by hand just after each harvest date.

All varieties of sweet sorghum remain completely recumbent two weeks after Hurricane Gustav, whereas, sugarcane has become considerably more erect. The inability of sweet sorghum to erect itself after lodging will make harvesting more difficult and losses will be greater.

We began to harvest the Dale and Theis sweet sorghum varieties on July 24 and completed the harvest on the 25th. Only the Dale and Theis varieties were harvested on these dates because they reached harvest maturity before the M81-E and Topper varieties.

Adding value to sugarcane has always been the mission of the LSU AgCenter’s Audubon Sugar Institute. But that mission has taken a new twist in these times of high fuel costs. One of newest projects is making ethanol from cane.

5/2/2008 It rained approximately 1.4 inches this past Saturday. This rain helped the sorghum to move quite a bit since last week’s blog.
