DA; FORTE, C. T.; FRANCESCHETTI, M. B.; TIRONI, S. P.; PERIN, GISMAEL FRANCISCO Wheat crop growth and development can be affected by weed infestation, especially ryegrass. Thus, the objective of this study was to evaluate the competitive ability of wheat cultivars wit h the diplo... ... Repository: BDPA Publication year: 2020
Sowing rate and its effects on forage yield of tetraploid ryegrass. Author(s): BARROS, L. M.; MITTELMANN, A.; PEDROSO, C. E.; BORTOLINI, F.; VERONEZ, R. P.; TAVARES, L. G. R. There is a shortage of information about the ryegrass crop (Lolium multiflorum Lam.), especially regarding the suitable sowing rate. Thus, the present work aimed to determine the most adequate sowing... ... Repository: BDPA Publication year: 2021
Pre-harvest herbicide application reduces the Italian ryegrass seed viability. Author(s): CECHIN, J.; MAZON, A.; RAPHAELLI, S. T. DE O.; AGOSTINETTO, D.; VARGAS, L. Italian ryegrass (Lolium multiflorum Lam.) is a troublesome weed found in temperate agricultural fields, wherein the future infestations depend on the soil seed bank. The aim of this research was to e... ... Repository: BDPA Publication year: 2020
