Abstract

This project was undertaken to develop and evaluate the performance of a planter that capable of planting common bean at predetermined spacing and depths. The planter, consisting of a frame, seed hopper, seed metering devices, seed tube/spout, adjustable furrow openers and covering device, and drive wheels. Physical properties of seeds involved in the study were investigated to optimize the design of planter’s components. Field testing was conducted in two locations namely at Boko and Erer substations of different soil types. In this experiment, two types of sowing methods were used, the animal drawn planter and manual sowing. The animal drawn planter is simple in design and easily operated and can be maintained by farmers. Randomize complete plot with three replications were used with plot size of 20x5.33m². The data was analyzed by two sample t-test statistical analysis of mean values, t- values and probability levels at 95% confidence interval. The parameters observed were sowing time, depth of sowing, speed of sowing, row spacing and plant spacing. The results showed that there were highly significant differences between the animal drawn common bean planter and manual for a parameter such as time for sowing, depth of sowing and speed of sowing. The animal drawn planter saves sowing time and labor requirements when compared to manual sowing. It also gave better average seeding rate for planter 73.4kg/ha than that of manual treatment (100 kg/ha). Effective field capacity and field efficiency of the planter was 0.026ha/hr. and 83.8% respectively. Hence, it is recommended that this efficient planter will be upgraded the planting machine in future design in multi row planter for increasing planting capacity per unit time.
