Abstract

Coffee tree lines (Coffea Arabica L. “Catimor”) (Rubiaceae) competition assay was performed to evaluate the correlations and the cause-effect relationships between row coffee productivity and other agronomic traits. The productivity showed the highest correlations with vegetative vigor, die-back, and ripening. It was verified, by path coefficient analysis, that vegetative vigor had the highest effect on productivity, and they also showed the highest correlation. Die-back also had direct effect on the productivity. There was no cause-effect relationship between productivity and ripening, regardless of the high correlation between them. The productivity was not effected by plant height, plant width, and branch curvature
