FALLAS, Róger; BERTSCH, Floria  e  BARRIENTOS, Mauricio. Nutrient absorption curves in papaya (Carica papaya L.) cv. “Pococí” during vegetative growth, flowering and the beginning of the harvest period. Agron. Costarricense [online]. 2014, vol.38, n.2, pp.43-54. ISSN 0377-9424.

In a commercial papaya farm located at Guácimo, Costa Rica, the requirements of nutrients, and the nutrient absorption curves for the Costa Rican high-yielding papaya hybrid “Pococí”, were established. The experiment was carried out in 2010 collecting complete plants, approximately monthly through the phenological cycle of the crop, from transplant until 9 months after wards. It was estimated that the “Pococí” hybrid (1600 plants per hectare) required approximately 354 kg.ha^-1 N, 101 kg.ha^-1 P₂O₅, 498 kg.ha^-1 K₂O, 174 kg.ha^-1  CaO, 106 kg.ha^-1  MgO and 40 kg.ha^-1  S;  these  required  quantities  are  mostly higher than those that are normally being applied by present fertilization programs in Costa Rica.
