Abstract
To know the effect that causes the number of offsprings on some morphological variable and the yield in established plantations of Coffea canephora Pierre ex Froehner, an experiment was developed in the period 2005-2009 in areas of the Alcarraza, Sagua of Tánamo municipality, Holguín province, with coffees of inferior yields at 0,2 t x ha–1, planted at 3.5 m x 3.5 m distance in the 1997 year, on a Brown gleyed soil without carbonates. The total pruning to the coffees was carried out and the treatments were conformed to 4; 5; 6 and 7 offsprings for trunk. Until the 24 months of having executed the pruning, they were not significant differences for the diameter of the cup. The height and the diameter of the shaft were shown inversely proportional to each other; the first one was increased at the same time with the biggest number of offsprings that decreased the second. The yield was increased until near values to the 2,0 t coffee berry x ha–1 (accumulated in the first 2 harvests) in all the treatments. Although they were not significant differences among these, in the yield the tendency was observed to its increase with the increment of the number of offsprings. When it becomes rehabilitated a plantation of Coffea canephora Pierre ex Froehner in density of 816 plants x ha–1, the biggest economic effect it is obtained ($14 477,44 x ha–1) when 6 offsprings are selected by each trunk.
