Evaluating the benefits of implementing soy-maize crop rotations in sub-Saharan Africa

摘要

Maize is one of the most important crops on the African subcontinent, accounting forover half of daily caloric intake in some regions. However, continuous cropping ofmaize has led to extensive degradation of soil and decreased crop productivity. Thecultivation of soybean holds great promise in improving agricultural systems in subSaharanAfrica. Introducing soy into rotation with maize is a method to diversify dietsand better nutritional status, reduce abiotic and biotic stresses, and improve soilfertility, all the while enhancing crop productivity and generating more income forfarmers.
