Use of glyphosate in the management of Panicum maximum cv. BRS Zuri intercropped with maize

ABSTRACT The intercropping between maize and forage species is an alternative commonly used within farming systems. Competition among crops may be a limiting factor in intercropping, compromising yield. Although necessary, the literature does not provide satisfactory answers on interaction of launched market recently, such as BRS Zuri, intercropped with maize. Therefore, techniques use herbicide subdoses come option to suppress growth, making simultaneous cultivation feasible. Thus, present study aimed evaluate effects glyphosate development Panicum maximum cv. Zuri Roundup Ready® (RR) how this reflects weed population, yield, biometric yield variables experimental design was randomized blocks treatments consisting six (0, 48, 96, 240, 480, 960 g acid equivalent [a.e.] ha-1) monoculture four replications. For conditions study, dose 480 a.e. ha-1 since there suppression adequate development. Maize affected by presence forage.
