Excerpt from Derris Culture in Puerto Rico The growing of Derris elliptica: in Puerto Rico is described and dis cussed with some reference to cultural methods used in the Far East. The Sarawak Creeping and Changi No. 3 varieties are commercially superior to other selections of derris that have been tested. Unshaded nurseries, described in detail, have proved a practical means of rooting cuttings on a large scale. The use of rooted cuttings reduces the amount of weeding required and assures a more uniform stand of plants in the field. Simple methods of transplanting rooted cuttings and applying fertilizer are presented. Little is known of the fertilizer requirements of derris. Propagating material of commercial Size is used most efficiently at a field Spacing of 3 by 3 feet, but weeding costs are reduced by closer Spacing. Large cuttings produce plants that cover the soil more quickly and yield more roots per acre than small cuttings. Trellising the vines increased the yield of roots 75 percent and the number of cuttings 300 percent over those not trellised, but the labor requirement for trellising may be correspondingly increased.
