| description | In the municipalities of Sabanalarga, Baranca, and Luruaco (Atlantico, Colombia), 4 intercropping trials were established using cassava var. Venezolana, millet var. Cuarentano, and improved maize var. ICA V 106 and ICA V 109 to determine the suitability of this type of cropping system for a region where the highest crop losses are due to summer droughts. Farmers in the area intercrop cassava var. Venezolana with local maize var. Cuba; no specific agronomic recommendations are known. Yields of cassava decreased when intercropped with maize and decreased even more when also intercropped with millet. Av. yields of sole cropped cassava were 14.26 t/ha. No differences were observed among maize var. ICA V 106, ICA V 109, and Cuba. Max. competition with cassava was observed in cassava//millet; local millet var. Cuarentano yielded highest (1.90 t/ha) in this cropping arrangement, followed by 1.6 t/ha in cassava//maize var. V 106//millet. This latter arrangement also gave the highest net returns, whereas the lowest net returns were obtained with cassava//millet. Statistical differences were observed among sites as well as in cassava and millet yields. Plans include further trials on planting distances for all 3 species; multi-site trials in the region are recommended to include this cropping system in the technological package being developed.

(AS- CIAT) En el area del departamento del Atlantico, en los municipios de Sabanalarga, Baranca y Luruaco, se establecieron cuatro ensayos de intercalamiento entre las especies de yuca Venezolana, millo Cuarentano y los maizes mejorados ICA V 106 e ICA V 109, con el objetivo de obtener conocimiento acerca de este tipo de arreglo para una zona donde las mayores perdidas de cultivo suceden por severas sequias en verano. El agricultor de la zona practica el arreglo yuca Venezolana//maiz criollo Cuba y no se conocen recomendaciones agronomicas especificas. Los rendimientos de yuca disminuyen cuando se intercala maiz y es mayor esta disminucion cuando ademas se intercala millo, siendo en prom. los rendimientos de 14,26 t/ha para el cultivo solo de yuca. Los maizes ICA V 106 e ICA V 109 y Cuba no presentaron diferencias entre si. La maxima competencia hacia yuca se hace en el arreglo yuca//millo; el millo criollo Cuarentano tiene su maximo rendimiento de 1,90 t/ha en este arreglo y el siguiente menor es 1,60 t/ha en el arreglo yuca//maiz V 106//millo, el cual arroja el mayor beneficio neto de todos; el menor es el de yuca//millo. Las localidades fueron diferentes estadisticamente, asi como los rendimientos de yuca y millo. Se espera adelantar nuevos ensayos de distancias de siembra para las tres especies y evaluar mas ampliamente en el area para incorporarlo como recomendacion al paquete tecnologico.
