Economic evaluation of alley farming of maize/beans with Erythrina poeppigiana in Costa Rica
An economic evaluation of alley cropping was carried out using data accumulated from a nine-year trial with maize and beans using mountain immortelle (Erythrina poeppigiana) with and without mineral N. Treatments without trees, using a mulch of Erythrina with and without fertilization were included for comparison. Both cost benefit and sensitivity analyses were carried out on varying costs of labor and the use of mineral N fertilizer. The results show that using the available maize varieties, even at lower opportunity cost for labor and at higher N prices, alley farming, with its serious soil degradation problems, does not currently appear to be a profitable alternative for maize and bean production in Costa Rica.
