The main limiting factor in crop productivity in Ghana and Africa has historically been a failure to provide farmers with high yielding and climate smart varieties, without which little else done to assist them can have much effect. In crop production systems, seed is the upper limit on what farmers can achieve bumper harvest and combat food insecurity.
Throughout history, intensification of local farms and national food supply systems has been catalysed by the introduction and distribution of seed of improved, higher yielding crop varieties. While tradition crop varieties embody a number of traits that allow them to grow reliably under local conditions, they also, with few exceptions, embody very low yield potential.
