Effect of pollarding frequency on biomass of Erythrina poeppigiana as a coffee shade tree
The use of pollarded Erythrina poeppigiana as shade tree in coffee plantations is apparently and old practice in Costa Rica. The tree is not native to this country but was introduced between late 19th and 20th century and was rapidly dispersed in the coffee and cacao areas. Currently, the Erythrina tree is widespread in the Turrialba valley (elevation 600-1300 m) and in the Central Valley (elevation 1200 m) where the species is always associated with present or past coffee crops. Pollarding carried out by Costa Rican farmers constitutes a long dated and functional practice, hence the objective of this study was to evaluate the amount of biomass produced by pollarding of Erythrina poeppigiana used as shade in coffee crop planted at a density of 280 trees/ha under different pollarding frequencies. Results showed that by pollarding once a year, 18.470 kg of dry matter per hectare are produced
