Greenhouses: Prolific tomato yields

In Nigeria, annual yields of tomatoes grown in greenhouses have dramatically increased to 264 t per ha compared to 7 t per ha for tomatoes grown in open fields, an increase of 3,800%. Significantly, previous periods of scarcity due to erratic rainfall are now met by the increased yields from the greenhouse-grown tomatoes, also helping to keep prices and imports down.
