Ugandan “Farm Boom ” - Uganda farmers plant 1.5 million Hectares to Hybrid Maize in the year 2025  Ugandan maize yields today are 1.5 MT/HA –imagine yield increase from 1.5 to 10 MT/HA or from current country production of 2.25 million MT vs. 15 million MT  NARO Maize hybrids are available that are bred to yield 7-9 MT/HA – a % yield increase  Uganda Maize yields of MT/HA have been produced– Fuels an immediate closure of yield gap  The “Farm Boom ” in Uganda - Large maize productivity increase drives an increase in net income to farmers  The “Farm Boom ” in Uganda – inputs needed for maize production – seed, fertilizer, herbicides, machinery, grain storage, transport, machinery, parts, concrete steel, grain merchandizing, food processing, etc.
