 This policy began to be implemented on a large scale throughout the Congo after the Second World War, by the colonial government.The scheme aimed to modernize indigenous agriculture by assigning plots of land to individual families and by providing them with government support in the form of selected seeds, agronomic advice, fertilizers, etc.The National Institute for Agronomic Study of the Belgian Congo, established in 1934, with its large experimental fields and laboratories in Yangambe, played an important role in crop selection and in the popularization of agronomic research and know-how.
