AbstractData are presented here on the effect of applications to sugarcane of 10, 20, and 30 pounds to the acre of the sodium salt of 2,4-D, acid basis, at three intervals (10, 20 and 30 days) prior to harvest. Field experiments were conducted at Humacao and Río Piedras following a randomized block layout. Each treatment was replicated six times. The mean available 96° sugar percent cane was 12.2 at both locations with very small deviations above or below it. No significant differences were observed between the mean Brix, polarization, purity, available 96° sugar percent cane, and tons of cane to the acre at either location.
