Development of a single-row push type plot seeder with mechatronic seed feeding device for corn (Zea mays L.) field breeding experiment

Abstract

The absence of an appropriate mechanization technology for lower stages of field breeding experiment is a common problem in seed research industry. This study was focused on the development of a corn plot seeder to be used in planting corn seeds for lower stages of field breeding experiments. The machine was equipped with mechatronic seed feeding device to provide an efficient way of sowing for every plot. Field testing and cost analysis between the Corn plot seeder and two other seeders were conducted to determine the performance and economic viability. Results showed that the Corn plot seeder can sow seeds at 0.49 ha/day with a field efficiency of 42.46 %. Its row/hill spacing was also at the optimum values of 70 ± 3 cm and 21 ± 4 cm respectively. It was able to sow 1 ± 1 seeds per hill and generated a 93% planting efficiency with a 7% missed hill. The Corn plot seeder had the highest capital investment of Php 27,380.00 but had the cheapest annual operating cost of Php 27,963.36. The push type corn plot seeder with mechatronic seed feeding device was the most efficient and economical machine for lower stage corn field breeding experiment.
