Book Chapter 1979

Autor: Leihner, D.E. Doll, Jerry D.

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 p...

Se describen algunas medidas de control cultural de malezas en yuca: calidad del material; sistema y densidad de siembra; interaccion tipo de planta x densidad y uso de coberturas. Para estudiar la interaccion tipo de planta x densidad de siembra, se sembraron las var. M Mex 59 (Vigorosa) y M Col...

Recent information on the biological balance between purple nutsedge (Cyperus rotundus) and cassava is analyzed; the possibilities of influencing this balance to favor cassava are also studied. The slow initial growth of cassava highly favors the development and propagation of C. rotundus, result...

Soil erosion and the productivity of cassava (Manihot esculenta Crantz) cropping systems, including forage legume intercropping, were monitored under natural rainfall conditions on Inceptisols in southwest Colombia. Trials were conducted over two cropping periods on moderate slopes. The best eros...

In view of the lack of information on the use of herbicides in polycultures including non-commercial crop species, 2 expt. were designed to identify herbicides and doses suitable for crop associations including cassava. A total of 6 products were tested single or in mixtures having been chosen fo...

CIAT has developed a new intercropping technology (cassava/grain legume associations) that tries to solve the numerous problems that arise in traditional intercropping systems. High-yielding cassava cv. with an erect, late-branching growth habit are recommended to minimize intercrop competition. ...

The management of cassava intercropping and its evaluation are described. Multiple cropping systems are defined: consecutive cropping and intercropping (mixed intercropping, row intercropping, strip intercropping, and relay intercropping). Basic biological and nutritional aspects of multiple crop...

Se presenta una descripcion del manejo de cultivos asociados con yuca y su evaluacion. Se definen lo que son los sistemas de cultivo multiple (cultivo consecutivo y cultivo intercalado o asociado-intercalado mixto, intercalado en surcos, intercalado en franjas, intercalado en relevo), se analizan...
