Maize has most market present in Ghana in terms of seed production and marketing. However, about 3% of maize area planted in Ghana is hybrids from the formal system whilst 87% of seeds was supplied.
by the informal system mainly OPVs and farmer’s saved seeds. This is partly due to fact many local seed producers don’t produce hybrid seeds but Open pollinated varieties. Imported hybrids are growing in popularity due to their superior yields performance and marketing by MNCs. There is limited production of local hybrids by private seed producers and local seed companies. Maize has the most developed EGS value chain in the country with the most active private sector participation. Of the over 40 MT of FS required in 2014 for local production, GLDB supplied less than 50% with the NARI’s and private sector producing to augment the supply. Maize accounted for 71% of improved seeds output in 2015 and obaatanpa (25 years old variety) accounted for 77% of total local maize seeds production of 2,105MT.
Cowpea seeds from the formal system are only able to plant 1% of area cropped. The informal system supplies 99% of seeds research has showed. Current output of 55MT supplies, and 5% of farmers replace seeds every 4 years.
Seeds from the formal system is able to plant 6% of area cropped in Ghana with the informal system supplying seeds for the remaining 94%. Current output of 213MT supplies 25% of farmers with replacement of seeds every 4 years.
Soya is also produced by smallholder farmers under rained conditions. Under these subsistence methods, soya yields average only 0.8 metric tons per hectare, although soya has been demonstrated to grow at yields of as much as 4.5 metric tons per hectare under the best commercial agricultural practices in Ghana. Crop rotation of soya with maize on commercial farms in Ghana will provide for improved fertility on fields with multiple crops per year. Although current production and consumption data for soya are not readily available, FAO estimates that Ghana imported soybean oil alone of between 2,700 and 7,826 metric tons annually between 2001 and 2007.
