This paper includes development stage and laboratory evaluation stage of this variable rate system. In this research, a centrifugal fertiliser machines with two discs were used to develop a variable rate controller. Step motors were used to apply variable rate application for these machines. A special system designed for connecting fertiliser rate plates and step motors.eninfo:eu-repo/semantics/closedAccesscentrifugal fertiliser spreadervariable rate controllerprecision agricultureConference Object4954N/AWOS:000254292100008
