ABSTRACT
Macronutrient accumulation in fruits and concentrations of these nutrients in leaves of fruit-bearing branches of arabica coffee were studied between anthesis and maturation. The experiment was carried out in a 2.0 × 1.0 m spacing of an arabica coffee orchard, collecting fruits and leaves of 18 randomized parcels at 12 sampling times, using a split-plot design. The largest accumulation rates of dry matter (DM), nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S) were observed at the rapid expansion fruit stage, among 79 to 85 DAA (Days after the anthesis). Compared to the other nutrients, Ca and Mg accumulation occurred quickly in the 1st suspended growth stadium.
