Design of Manually Operated Four Rows Rice Seeder

In Ethiopia, rice is one of the targeted agricultural products that has received adequate attention in the promotion of agricultural output. It is regarded as the "Millennium Crop" and is anticipated to help ensure food security in the nation. As a result, over the past few years, its production has increased. Despite the growth, there are still a lot of production system issues that need to be resolved, with planting technique leading the list. The farmers continued to use time- and labor-intensive traditional seed-broadcasting techniques, which led to a sharp reduction in output due to an unfavorable plant population. Consequently, in order to maintain the ideal plant density and get around the issues with the conventional method of disseminating the seed on the farm; there was efforts have made to design suitable planting machine for rice. Then depends on the binary dominance matrix traditional seeding techniques (broadcasting), manual planting technique in rows and the newly designed manually operated four rows rice were evaluated and it was found that newly designed seeder was better than manual method in all parameters. The machinability aspect, which comprises installation, simplicity, durability, choice of material, machine, low pricing, and prolonged life span when operated with high utilization with minimal downtime, was properly taken into account in order to achieve this design target and goals
