In 2002, four kenaf varieties were selected
(Dowling, Tainung 2, Everglades 41, Gregg) to assess potential yields and to
decrease stalk diameter to commercial standards by increasing population density.
Density was increased by drilling seed in rows 7.5 inch apart with a Hege 1000
series drill/planter. Plots were manually weeded until time of canopy
(approximately 1 month). Stalks were allowed to dry in the field and were
harvested 12/09/03.
