- Runoff curve numbers for Hawaiian sugarcane and pineapple fields were derived from actual rainfall-runoff data used to adjust handbook values. These handbook values were based mainly on experience under mainland conditions and soils. The data-based curve numbers were slightly lower than previously used handbook values for sugarcane. They were considered lower jor pineapple fields where field roads occupied 11 to 20 percent of the area. Observations suggest that major portions of the runoff come from road areas and that more intensive conservation measures and maintenance programs for these roads would help reduce this runoff and subsequent erosion.
