Prospects for sustainable intensification of soybean production in sub-Saharan Africa por Debnath, Deepayan, Babu, Suresh Chandra

“…We find that increasing soybean yield by 50% can increase the total returns from soybean production by 186 million LC (local currency) in Ethiopia and 36 billion LC in Nigeria. We show that soybean yield growth alone is enough to boost soy oil production, as the crushing of the beans produces 18% oil and 79% meal. …”
