Six weight ranges of ginger seed setts (14 to 28 g; 29 to 43 g; 44 to 57 g; 58 to 85 g; 86 to 114 g; and 115 to 128 g) were evaluated for yield in Gurabo, east-central Puerto Rico. The soil in the experimental area is of the Mabi clay series (fine, montmorillonitic, isohyperthermic Vertic Eutropepts). Rainfall during the nine-month cycle of ginger (March-December 2005) was 1,744 mm (68.6 in); drip irrigation was also provided on a regular basis. No significant differences in yield were found between the two heaviest seed sett weight ranges used for planting, 115 to 128 g and 86 to 114 g. The 115 to 128 g setts yielded higher (a=0.05) than the remaining four ranges. The average yield of the 115 to 128 g setts was 24.59 mt/ha, whereas that of the 86 to 114 g setts was 18.47 mt/ha. The 86 to 114 g setts yielded significantly higher than the 14 to 28 g and the 29 to 43 g setts. Results indicate that the seed sett weight range of 86 to 114 g is the most feasible weight for planting ginger in east-central Puerto Rico.
