Vliv rozdílných typů zástinu na vybrané vlastnosti plantáží Coffea arabica v okolí města Villa Rica, Peru
 Ehrenbergerová, Lenka
Coffee belongs to very important crops in the world and it is traditionally grown in agroforestry systems. During the five years the four coffee plantations with different type of shading were studied in the foothills of the Peruvian Andes. The highest amount of carbon was found in the plantation shaded dominantly by Eucalyptus spp., followed by Pinus spp., Inga spp. and non-shaded site. The microclimatic characteristic measurement shows that shading reduces the mean air and soil temperatures and increases the air humidity, compared to the non-shaded site. It was recorded drier soil conditions at the shaded site. At all plantations, coffee variety and age had a significant effect on Coffee Leaf Rust incidence. The value of the timber stored in shade trees varied significantly. There were different results for different shade trees species (from 2% to 72% of the annual income from coffee production).
