For the uniform seeding over the field, the performance of seed metering device is vital. While a seed drill is on work, during the field operation undesired situation such as slipping and skidding of the ground wheel, vibration, seizing, and jamming on the chain-sprocket system may occur especially at high speed. To overcome these problems, it was aimed to develop an electronically controlled Seed metering system (ECSMS) for seed drill. The developed system was incorporated with geared dc motor, proximity sensor, variable speed rate controller, and microcontroller as the prime components. The performance evaluation of an electronically controlled metering system was done at four different levels of speeds 2.4,3,4 and 5 km/h at 20 cm row to row spacing under the laboratory condition. A comparison was done between the set seed rate and actual seed rate regarding the seed rate variation and uniformity. The average percentage variation between the actual seed rate over the selected input seed rate was found to be within the range of -3.10 to 3.141 % at a different level of seed rate and forward speeds. ECSMS enabled the suggested optimum seeding rate, a quick and simple setting possibility, synchronize and real-time control, the ability to work under higher speeds.
