Yield loss and economic thresholds of yellow nutsedge in irrigated rice in func...
Agostinetto, Dirceu; Westendorff, Nixon da Rosa; Ulguim, André da Rosa; Nohatto, Marcos André; de Avila, Luis AntonioWeeds cause reduction in the rice yield. Little is known about the competitive ability of yellow nutsedge (Cyperus esculentus) with rice and the extent of the economic threshold (ET). The aim of this study was to determine the fit of the regression model to estimate hyperbolic yield losses and ET of yellow nutsedge in rice due to the cycle of cultivars (BRS Querência - Early cycle and IRGA 424 - mid cycle). For...
