Effect of Six Levels of N on the Growth of Sanders Dracaena (Dracaena sanderiana, Hort.) at a 47 Percent Shade

Abstract

Rooted cuttings of Sanders Dracaena (Dracaena sanderiana, Hart.) were grown in a 1:1 mixture of Cataño sand and peatmoss. They received regularly a mineral nutrient mixture containing variable levels of N in addition to P and K. After harvesting for a definite period of time, the data were analyzed by variance and through the fitting of the fertilizer-yield curve Y = A/1 + B (C - X)2 . The analysis reflected maximum yields of number of cuttings, total weight, root weight and total top growth with applications between 1200 and 1400 lb of N/acre/yr (aprox. 1300-1600 kg/ha/yr).
