Performance Evaluation of Manually Operated Multi-Crop Planter for Okra

Abstract

A manually operated multi crop planter was evaluated for its performance in laboratory and field test. The parameters under study in laboratory test was calibration test, seed germination test seed damage test, uniformity of intra-row seed spacing, while the field test examined the field efficiency, field capacity, draft, hills populations, missing hills and average seed spacing within the row. The average amount of seed in fifty revolutions of drive wheel was observed 14.70 g during calibration. The planter metered out one seeds per discharge at average planting depth of 3 cm with minimum seed damage of 2 % during operation. It has a field efficiency of 89.83% and field capacity of 0.11 ha/hr with an average planting depth and spacing of 3 cm and 18.76 cm respectively.
