SOWING PERFORMANCE BY A METERING MECHANISM OF CONTINUOUS FLOW IN DIFFERENT SLOPE CONDITIONS
(Soc Brasil Engenharia Agricola, 2016-09-01)
One of the reasons for the success of a productive culture is the correct sowing. Therefore, the seeds must be properly dosed, deposited and not damaged by the metering mechanism of the seed drill. So, the aim of this study ...
