La fertilización fosfórica del Coffea arabica L. en suelo Ferrítico Rojo Oscuro. Parte I. Fertilización mineral
In a field experiment in 1982-97 in Pinares de Mayari, Cuba, coffee cv. Caturra Rojo grown under the shade of pines (Pinus cubensis) was given 0, 50, 100, 150 or 200 kg P ha-1 year-1, with 200 or 300 kg N and K ha-1 year-1 in the first production cycle (1982-87) and 180 or 240 kg N and 150 or 225 kg K ha-1 year-1 in the second and third cycles (1988-92 and 1993-97). Yields were higher with the higher N and K rates, and with these rates yield increased with increasing P rate up to a plateau at 150 kg.
