Abstract
In the September month of the 2019 year an evaluation to plantations of Coffea canephora (Pierre) ex Froehner var. Robusta of three years of age was carried out, propagated by stakes in the Basic Units of Cooperative Production José Martí, 24 of February and Cooperative of Credos and Services Rolando Pérez Quintosa. The objective was to evaluate plantations morphologically for stakes of Coffea canephora in three towns of the Granma province. In a 1 hectare were traced 10 blocks of 40 plants each one. To 120 plants in each town were measured the height of the plant, the diameter of the stalk, the number of plagiotropic branches, the number of knots, the top diameter and the number of offsprings. A transformation of the variables with the equation square root to achieve bigger approach to the distribution normality and homoscedasticity was carried out. The variance analysis was applied to the variables and the contrast of halves based on the test of Duncan, assuming same variances for the determination of significant differences among the variables studied by means of the employment of the software Statistic version 8. Significant differences existed for the variables studied in each one of the towns, showing the plantations of the town The Cristina the best results.
