Summary of the analysis variance for the weed density (plants m -2 ) at 120 and 150 DAA, weed dry mass (g m -2 ) at 150 DAA, weed efficacy (%) at 120 and 150 DAA, phytointoxication (%) at 30 DAA and sugarcane yield (Mg ha -1 ) at 322 DAA in the two years of evaluation Year 1 and Year 2 as a function of herbicides treatments (T) and sugarcane straw (S) amount kept on the soil after harvest
