| Sumario: |
This study was conducted at three places: Palmyra, Alto Lino and Horqueta in the district of
Boquete, from 2009 to 2010 with the objective of evaluating the effect of different species
of shade trees on coffee(Coffea arabica var. Caturra) production. In the three sampling
sites were determined a coffee area with shade trees and one without shade trees in circular
plots of 1000 m². In each plot five shrubs of coffee chose themselves at random. In each
shrub two branches were chosen at random in wick the mature fruits were counted and
weighed to compare the results between plots. By comparing the total average number and
weight of coffee fruits in the shade and no shade, no significant differences (P> 0.05) but
between locations showed highly significant differences (P <0.01), probably due to the
difference in altitude, diversity of tree species and pruning shade between locations. Were
collected and identified 9 families, ll genera and 10 species of trees associated with the
cultivation of Coffea arabica, in three plots of 1000 m². In each plot, Hive randomly chosen
coffee. In each coffee tree two branches were selected at random. Mature fruits were
counted and weighed to compare the results between plots. The most common and most
abundant in the areas of Alto Lino and Horqueta was: Inga oerstediana, family Fabaceae.
Among the native or endemic species include: Inga oerstediana, Conostegia obtusifolia,xalapensis, Myrsine coriaceae, Aulomyrcia tomentosa. Palmira
is more diverse Horqueta y Alto Lino, but Horqueta and Alto Lino Inga are trees for shade
in different proportions, so that in Alto Lino there is a balance between Inga shade trees
and other species.
Keywords: coffee, tree shade, tree without shade, production.
