Plantain is a staple and inexpensive food in the tropical and subtropical areas of Latin America. Its consumption has been increasing steadily in recent years, but poor yields are common due to inadequate inputs and low technology management practices. Experimental work has proven the advantages of higher plantain population densities which include: Higher yields of high quality corms for sale and subsequent seed-stock, better crop cycle planning that match harvest time with the best market conditions, better land-use that allows one hectare of high density plantain to produce as much as 3 to 5 hectares of conventional planting, and lower incidence of pests, diseases and weeds. Results from El Castillo in 1997 showed the positive effect of adequate nutrition on plantain yield. A plant population density of 3,332 plants/ha produced a corm yield of 34.6 t/ha with 100-40-210-60-150 kg/ha of N-P2O5-K2O-MgO-CaO. COLOMBIA-03
