Madagascar periwinkle is an important medical plant because it has 150 alkaloids especially two important and expensive ones, vinblastine and vincristine, the effective alkaloid for leukemia therapy. Greenhouse experiment on Mabbon soil series was, therefore, carried out at Kasetsart University to search for limiting plant nutrients controlling growth and alkaloid yield of a tall pink color flower periwinkle using a randomized complete block design with 16 treatments and 4 replications. The treatments included no nutrient in sand, no nutrient in soil, complete nutrients in sand, complete nutrients in soil, -N, -P, -K, -Ca, -Mg, -S, -Fe, -Mn, -Zn, -Cu, -Mo and -B (applied all essential nutrients except the indicated one). These are summarized results, nitrogen phosphorus and sulfur were very strong, strong and moderate deficiencies respectively, deficiencies of N and P reduced yield of the crude alkaloids in top and root and omitting iron and zinc also tended to reduce yield and content of the crude alkaloids in root.
