Densidades de siembra de dos variedades comerciales de crisantemo, Chrysantemum morifolium Ramat en Piendamo (Cauca)
The behavior and agricultural characteristics of two kinds of Chrysanthemum (White Marble and Yellow Polaris) were evaluated in terms of yield and quality of the product. Two different kinds of planting systems were applied (single stem and pinched stem). The experimental design in randomized whole blocks for each variety and system including four density treatments (80, 90, 110 and 115 sterns per 1.05 m2) was repeated six times. The experimental unit was of 2.10 m2; 1.26 m2 were harvested. A strong discrepancy between the quantity and quality of the product was observed. The highest yields were obtained with densities of 110 and 115 stems per 1.05 m2. However, the experimental units dis not always met both requirements of a diameter greater than seven cm and three or more marketable flowers per stem. If maximizing production of acceptable bunches is taken as a decision variable, a density of 90 sterns per 1.05 m2 with a 3/3/2/2/2/3/3 arrangement with pinched stern for Yellow Polar is seems a better alternative. As for White Marble, it would be better to have 80 stems per 1.05 m2 with a 3/2/2/2/2/2/3 arrangement in the single stem, but the probability of acceptance is only 0.666. In addition, White Marble showed more susceptibility to dwarfism.
