• Resumen

  • The effect of two systems of handling of the soil was evaluated (with parterre and without parterre), three spacings (1.0 m x 1.5 m; 1.5 m x 2.0 m and 2.0 m x 2.0 m) and five ages after the planting (30; 60; 90; 120 and 150) days on the phenology of the silk flower. The statistical design was of randomized blocks design in factorial model 2 x 3 x 5, in portions subdivided in the space and in the time. The management systems of the soil and the spacings didn"t influenced the phenology of the silk flower. However significant effect was verified for the appraised ages, being verified positive lineal response for number of leaves, primary germinate, height and diameter of the phenology plant.
