Recomendaciones para el uso del nuevo herbicida pre-emergente "GOAL" en yuca
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...
The type and magnitude of losses in cassava caused by Cyperus rotundus were determined. Two field expt. were conducted at Instituto Colombiano Agropecuario-Caribia exptl. station, Magdalena (Colombia) at 35 m.a.s.l. The location has an annual mean temp. of 280 degrees Celsius, mean annual precipi...

Perdidas en el rendimiento y la calidad de la yuca (Manihot esculenta Crantz) causadas por coquito (Cyperus rotundus L.)
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 disea...

The effects of cutting storage on cassava root and branch production as well as on other crop characteristics (wt. loss, percentage of viable cuttings, sprouting 80 days after planting, final stand, no. of seed- cuttings/plant) were studied under field conditions in the banana growing zone of San...
