| Miêu tả: | The fertilizer application at a constant dose of 150 kg N, 120 kg P2O5 and 200 kg K2O ha-1, at different plant growth stages of Curcuma longa were evaluated in Guatuso, Alajuela from July 2002 through February 2003. Density was 47619 plants ha-1. Treatments were 2 fractioning types, starting at day zero (0-30-60 90 and 0-30-60-90-120 days) versus starting at 30 days (30-60-90 and 30-60-90-120 days). A Complete Randomized Block experimental design was used. The application period produced significant differences on yield. Treatments with 4 and 5 applications starting at planting (0-30-60-90 and 0-30-60-90-120 days) showed the highest yield plant-1 with 0.408 and 0.488 kg, respectively, as well as the highest yield ha-1 with 19.3 and 23.2 t, respectively. |
