Effects of organic fertilization on the morphometry and productivity of Sarchimor 4260 coffee in its second harvest

Abstract

With the objective of determining the effect of different sources of organic fertilization on morphology and productivity of Arabica coffee Sarchimor 42 60 (Coffea arabica L) in its second harvest. A research plot was evaluated in a completely randomized block experimental design with a 4x3+1 factorial arrangement, factor A identified as fertilization sources; with four levels; Worm humus (HL), mycorrhiza (MZ), agricultural gypsum (YA) and micro essentials (ME), and factor B the doses, in which three doses of each treatment were tested; several variables of morphological character were analyzed, as well as productive. The results obtained determined at the morphological level, that plant height, stem diameter, number of nodes per branch, leaf length and leaf diameter, that MZ in doses of 0.5 g/plant, HL in doses of 50 and 150 g/plant, and YA in doses of 50 and 100 g, all with the inclusion of 25 g urea were those with the best performance. The productive results, based on the variables: weight of 100 ripe fruits in g, weight of production/plant, yield to gold coffee kg/ha, and yield to gold coffee qq/ha, showed that the best treatments were HL at a dose of 50 g/plant and YA at a dose of 50 g/plant; it was concluded that the treatments with organic fertilization performed better than the treatments in which only chemical fertilizers were applied.
