Abstract
Abstract ‘Christian Dior’ and ‘Happiness’ roses on Rosa fortuniana stock, fertilized with 3 rates each of N, P, and K factorially combined, were grown for 3 years at Ft. Pierce, Florida. All fertilizer was applied at the beginning of the experiment under plastic mulch just before the bushes were planted. About 2300 lb./A of N on ‘Christian Dior’ and 2100 lb. on ‘Happiness’ produced the greatest number of flowers. Leaf N at 18 months was also maximized by 2100 lb. N. Nitrogen levels maximizing stem lengths were slightly lower. The independent effects of P were minor and low levels best, perhaps because residual soil P at start of the study was adequate. Flower production decreased with K fertilization beyond low rates, whereas stem lengths increased to a max at about 1700 lb./A. At times, various nutrient interactions were noted. ‘Christian Dior’ consistently yielded more flowers than ‘Happiness’. With minor exceptions, ‘Happiness’ had longer stems.
