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