Abstract
Extending duration of moderately used 1-day preharvest floods in sugarcane (Saccharum spp.) could improve Florida sugarcane insect control, freeze protection, and soil conservation, and reduce unwanted P discharge. The purpose of this study was to compare the effects of flood duration and month of flood application on theoretical recoverable sucrose (TRS), cane yield, and sucrose yield of four sugarcane cultivars. During the plant-cane and first-ratoon crop cycles, 0-, 10-, or 20-day floods were applied in November or to lysimeters planted with cultivars CP 72-2086, CP 80-1827, CP 89-2143, and CP 92-1666. Cane and sucrose yields of flooded treatments were at least as much as those of non-flooded controls. These results warrant research to quantify the profitability of preharvest flooding of sugarcane, recognizing that these 10-20 day floods had minimal impact on yields while offering potential economic returns from other agronomic and ecologic benefits.
