A new study published in HortScience finds promise in a common legume used as an effective crop cover for organically produced onions.


Researchers at North Carolina State University recently released the results of a two-year experiment designed to assess the efficacy of summer annual grass (foxtail millet) and legume (cowpea) cover crops in different mixture ratios or monocultures. The researchers also analyzed rates of soybean meal as nitrogen amendment on overwintered, no-till, organically managed onion production. Foxtail millet and cowpea were compared with a bare-ground control for weed suppression and nitrogen contribution when followed by organically managed no-till bulb onion production.
