Farmer Field School Trials of 2:4:2 Maize/Legume Intercropping

By: Tim Motis, Biriori Dieudonne, and Robert Morikawa

Excerpt: Farmers often struggle to maintain the productive capacity of their soils, especially where they lack enough land for a fallow (rest) period between crops. Leguminous green manure/cover crops (GMCCs) can help; in association with rhizobial bacteria, legumes convert nitrogen from the air into a form that plants can use. Many tropical legumes have deep, extensive root systems that can take up nutrients which leach past the root zones of other crops. Thus, even on poor soil, they can produce an abundance of nutrient-rich, plant-based mulch. When left on the field, this mulch builds soil organic matter and fertility. Legumes also help suppress weeds and, depending on the species, produce beans and foliage for human and/or animal consumption. While these benefits are well-recognized, the benefit of GMCCs to small-scale farmers depends on how well they are integrated into smallholder cropping systems (see BPN 7 for information on legume selection and planting strategies).

ECHO Global Farm, United States of America

Did you know that of 250,000 identified plant species worldwide that only 30 species provide 95 percent of our global food energy needs? And that only three of these crops – wheat, maize and rice – provide half of the world’s food?   With severe weather extremes and other risks to global food security, many agricultural experts agree that global cropping systems should be as diversified as possible. As small-scale farms are particularly vulnerable to climatic and economic instability, u...
