Interference Periods of Weeds in Maize in No-Tillage and Conventional Systems at High Altitudes

Interference Periods of Weeds in Maize in No-Tillage and Conventional Systems at High Altitudes

ABSTRACT: The objective of this study was to determine the coexistence periods of weeds (CTWR = critical timing of weed removal) and control (CWFP = critical weed-free period) in maize crops in no-tillage and conventional systems at high altitudes in southern Brazil. To this end, four experiments we...
