Agronomic and economic benefits of nitrogen contributed by legumes in live-mulch and alley cropping systems
The challenge facing research on increasing food production in tropical Africa is to develop low input systems that are not only sustainable but also economically viable. At the International Institute of Tropical Agriculture, substantial resources are devoted to research on alley cropping and live-mulch systems. These are among the potential alternatives to the bush fallow system that would sustain food production with low purchased inputs in the humid and subhumid tropics.
