Abstract
The aim of the study was to describe the morphological development of four Arabica coffee genotypes (two hybrids and two varieties) during the first year of growth, and their response to the application of soil fertilization. The methodology was experimental, applying a randomized block design with a 4 x 2 factorial arrangement for the quantitative variables, where factor A was the varieties: Sarchimor 4260, Red and Yellow Bourbon, and Catuai, and factor B was the doses of: agricultural gypsum 50 g plus 25 g of urea and earthworm humus 500 g plus 25 g of urea. The comparison of means was performed using Tukey's test at α = 0.05. Infostat software was used for the statistical analysis. Quantitative and qualitative morphological variables were analyzed. The Chi-square test was used for the analysis. The results determined that, at a morphological level, in the first year, the highest plant height and stem diameter were observed in the Yellow Bourbon variety, and there were no statistical differences for the soil fertilization factor or for the interactions (genotypes vs. soil fertilization), while for phenotypic variables, the study determined that there were no statistical differences. The leaves of all cultivars are elliptical with an apiculate apex, leaf color is green, and the shape of the canopy is rectangular. It was concluded that the differences shown are possibly due to the genetic characteristics of the studied materials.
