ABSTRACT: Experiments were conducted at the CSIR-Crops Research Experimental station at Kumasi, Ghana, to determine the effects of seed sorting and planting device on yield of maize in the 2014 major growing season. Two jab planters were used to plant sorted and unsorted seeds. The control treatment was cutlass planting of unsorted seed. One of the jab planters was imported from China; and the other was fabricated in Ghana. The experimental design was a randomized complete block with 3 replications. Planting one hectare of maize with the Chinese planter took about 10 hours, 36 minutes; the local planter took 12 hours 39 minutes, whilst cutlass took 29 hours 36 minutes. Seed sorting and planting device had no significant effect on maize yield. However it was faster, cheaper and economically more viable to plant with jab planter than with cutlass.
