Soaked okra seed is recommended for a field planting for better germination percentage. Engineering properties of two seed varieties (Pusa-A4 and Punjab-8) were studied for water soaked condition for 24 hours and on the basis of these properties, an inclined plate was designed for the sowing of soaked okra seeds. Subsequently a metering mechanism of okra was developed and preliminary evaluation of the developed metering mechanism was conducted in the laboratory on following parameters: three type of inclined plates (A, B and C), three angle of inclinations (45°, 50° and 55°) and four forward speeds of operation (1.0, 2.0, 3.0 and 4.0 km/h). The performance of metering mechanism was evaluated on the basis of average spacing, multiple index, missing index, quality of feed index and seed rate. A selection of the angle of inclination and type of metering plate for the metering system was purely based on average seed spacing and index values. The best combination found in laboratory evaluation for Pusa-A4 was for plate A at 2 km/h forward speed and 45° angle of inclination were recommended for field sowing. Similarly, for Punjab-8 was plate B at 3 km/h forward speed and 50° angle of inclination was recommended.
