Some cultural control measures of weeds in cassava are discussed: quality of the material, planting system and density, density x plant type interaction and use of mulching. In order to study the interaction plant type x planting density, var. M Mex 59 (vigorous) and M Col 22 (nonvigorous) were planted in plots of 7500 and 15,000 plants/ha; and 3 levels of weed control were established: complete, intermediate and no control. The vigorous var.

Multiple cropping, sequential cropping, intercropping, mixed intercropping, intercropping in rows, in strips, relayed intercropping, cropping patterns, monoculture, crop rotation and land equivalent ratio are defined. The characteristics of multiple cropping and intercropping with beans are discussed; for the latter problems of competence are discussed (light, CO2, water and nutrients). Some cultural practices are recommended for cassava/bean intercropping: soil and fertilization type, water availability, propagation material, and weed, pest and disease control.

En la Estacion Experimental "Quilichao", del Centro Internacional de Agricultura Tropical (CIAT), depto. del Cauca, Colombia, se realizo un ensayo para evaluar el valor nutritivo y el consumo selectivo de Desmodium ovalifolium CIAT 350. Se usaron ovinos machos enteros de la raza Africanos, con un peso metabolico (P0.75) entre 7.89-9.77, a los cuales se suministro forraje fresco de D. ovalifolium a niveles de 30.245 g de MS/P(0.75) y de 5 edades de corte: 50, 80, 100, 125 y 145 dias; el ultimo corte coincidio con el inicio de la estacion seca.

This audiotutorial unit (cassette, printed script, 76 color slides, study guide, self-evaluation test), prepared by the Communications Support Unit at CIAT, is available for use with a manually or automatically synchronized slide projector/cassette tape reccorder. Each unit is a vailabIe from the Distribution Office at a cost of US$ 50; photocopies of the study guide alone can be obtained from the Cassava Information Center. The objective of this unit is to present some of the results of research conducted by the physiology Section of CIATs Cassava Program.

Conference Papers & Reports
The low cassava yields obtained in L.A. at present are the result of a complex of problems: 1) deficient quality of planting material, which results in low sprouting, poor rooting and little initial vigor; 2) inadequate land preparation and planting systems; 3) control systems for pests and diseases are unknown and weed control, untimely; 4) some local var. have a low yield potential. The CIAT Cassava Program has developed a set of simple low-cost practices aimed towards increasing cassava yields.
