A seed metering mechanism of conventional precision planters are usually driven by ground wheel with chain and sprocket system and these mechanisms are of mechanical type. They are less efficient as there is a number of losses while transmitting the power. Due to continuous friction between moving parts, these devices are subjected to wear and tear; hence they require frequent maintenance. To improve the planting performance of precision planters, the best substitute is to develop an electronic meterized planter for maize. The design and development of electronic meterized planter includes main frame, hopper, metering unit, furrow opener etc. The speed synchronization between ground wheel and metering unit is vital at it has been taken care by electronically.
