ABSTRACT • This work was developed in productive areas of the municipality “Calixto García", county Holguín, a study was carried out to determine the behavior of the yields in systems of cassava-beans alternation, the objective of the work consisted on evaluating the productive behavior in intercropping of both cultivations in the municipality. This investigation was developed in the cultivations cassava clone “Selección Holguín” and bean variety Carita Blanco with a cycle of 270 days for the cassava and 70 days for the bean it has more than enough alkaline soils. The following indicators were evaluated: quantity of tuberous roots for plant, weight average for plant, yield of the cultivation in t ha-1, presence of nodules in the system radicular of the bean, the Index of Efficiency of the Earth (IET) and the economic evaluation. The reached results showed differentiated answers of the indicators evaluated in each treatment, standing out the treatment II (mixed fertilization starting from the combination of organic matter to reason of 5 t ha-1 and micro fertilizer dose with the help of it formulates complete to reason of 10 g for plant with bean alternation) with more yields, results economic and bigger presence of nodules on the rest of the treatments.

Palabras clave : yield; alkaline soil; Cowpea; Soil organic matter; Manihot esculenta; Vigna unguiculata.
