Technical Abstract: Research was undertaken during 1994 to study the effects of multiple harvests on kenaf forage yield and quality. Seven kenaf varieties (Cubano, Everglades 41, Everglades 71, Guatemala 48, Indian, Tainung#1, and Tainung#2) were planted on May 14, 1994 in a RCBD with three replications. Each replication consisted of four beds, each bed being assigned randomly to one of four treatments (T1 = harvest at 85 DAP + final harvest of regrowth, T2 = harvest at 92 DAP + final harvest of regrowth, T3 = harvest at 99 DAP + final harvest of regrowth, and T4 = final harvest). All plants in a plot were harvested approximately 0.25m from ground level at 85, 92, and 99 DAP. A sample from each plot was used for determination of crude protein and fiber content. The regrowth was sampled for crude protein and fiber content on November 9, 1994 approximately 92, 100, and 107 DAP following first harvest, respectively. The dry matter yields (kg/ha), averaged over varieties, ranged from 12506 for T1 to 15688 for T2. T1 had significantly lower yield than other three treatments. The dry matter yield from T4 (14905 kg/ha) was not different from that of T2 or T3 (14433 kg/ha).
