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...

The methodology used for better conservation of the quality of planting material and to reduce the losses caused by the inadequate storage of cuttings is discussed. Generally, it is recommendable to shorten the storage period as much as possible. General conditions for the conservation of cutting...

Se discute la metodologia utilizada para conservar mejor la calidad del material de siembra y reducir las perdidas ocasionadas por el almacenamiento inadecuado de las estacas. En general, se recomienda reducir al max. posible el periodo de almacenamiento. Se enumeran las condiciones generales par...

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...

The rainfall erosivity (R) and soil erodibility (K) factors of the Universal Soil Loss Equation (USLE) were determined on two sites in the Colombian Cauca Department over a five year period when rainfall was mostly lower than average. The results showed that the high erosion potential of the soil...

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...

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...

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...
