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...

Autor: Ruppenthal, M Leihner, D.E. Steinmuller, N. El-Sharkawy, Mabrouk A.

Erosion trials under natural rainfall were conducted at two locations in the Andean hillsides of south-west Colombia on moderate slopes. Sediment-bound losses of seven cassava (Manihot esculenta) cropping systems per cropping period ranged from 26 to 1726 kg ha?1 for organic matter, 0.9 to 65.5 k...
