Abstract
As Louisiana farms continue to get larger and more diversified, more sugarcane (Saccharum spp. hybrid) acreage is being planted both earlier and later in the cropping season. This research was initiated to determine if the yields of five cultivars were affected by August, September, and October planting dates in Louisiana. CP 70-321, LHo 83-153, CP 79-318, LCP 85-384, and HoCP 85-845 were hand-planted during mid-Aug., mid-Sept., and mid-Oct. in 1996-1999. Data collected at harvest included stalk number and weight, cane yield, sucrose concentration, and sugar yield. For the plant-cane crops, optimum sugar yields for CP 70-321, LHo 83-153, and HoCP 85-845 were obtained with an August planting. These cultivars had similar yields with September and October plantings. The plant-cane sugar yield with the August planting for these cultivars averaged 14.4 Mg ha-1 compared with 12.4 and 11.4 Mg ha-1 for the September and October plantings, respectively. Higher sucrose concentration and higher stalk populations for the August planting contributed to this yield increase. Planting date did not affect cane or sugar yields of the plant-cane crops of LCP 85-384 and CP 79-318. For HoCP 85-845, the October plantings produced ratoon cane yields that averaged 13.8 Mg ha-1 compared to 12.7 and 13.4 for the August and September plantings, respectively. Ratoon sugar yields were not affected by planting date for all other cultivars. Producers should attempt to plant sugarcane cultivars sensitive to planting date in August to insure stand establishment and optimum yields as the crop begins a production cycle that can last four to five years.
