Agroecological Intensification Through Crop Diversification and Cover Cropping in East African Highlands

Abstract

Agroecological practices are essential for sustainable intensification. This study assessed the effects of intercropping legumes with cereals and incorporating cover crops (e.g., Mucuna and Crotalaria) on maize productivity, weed suppression, and soil health in the East African Highlands.
Intercropping increased maize yield by 18% and reduced weed biomass by 33%. Cover crops improved soil nitrogen and organic matter content. Farmers reported enhanced fodder availability and soil moisture retention. Agroecological intensification proves feasible and beneficial for smallholder systems under climate variability.
