Seed metering mechanism is an integral part of any planter. A seed metering mechanism was developed aimed to meter spherical seeds of okra. It consisted of cells termed 'Anjul' (a double handful) on its periphery, seed box, feeding chute, cleaning brush and seed capturing conical funnel. It was evaluated for three cell sizes-7 mm, 8 mm and 9 mm at three peripheral speeds of seed metering roller- 1.2 kmh-1, 1.4 kmh-1 and 1.6 kmh-1. Influence of cell size and peripheral speed of seed metering roller on seed rate and cell fill percentage was studied. The seed rate of okra seed varied between 12.89 kgha-1 to 22.99 kgha-1 for different combinations of the cell sizes and the peripheral speeds. The cell fill percentage of the three cell sizes for okra seed ranged from 42.80 to 54.72 for different combination of the cell sizes and the peripheral speeds of the seed metering roller. Optimum values for planting okra seeds were found to be 7 mm cell size at peripheral speed of seed metering roller of 1.4 kmh-1 for a desired seed rate of 13.75 kgha-1.
