Intervention effect Delayed planting reduced cover crop growth rate and final biomass except for radish.
Observation February cover crops left the least residue by maize planting.
Association February planted cover crops resulted in higher weed dry weights at 3 and 6 WAP.
Intervention effect April planting improved soil nitrogen more than earlier plantings.
Observation Grazing vetch and radish gave the greatest soil nitrogen improvement.
Observation Maize yields after the other cover crops were comparable.
Recommendation The authors conclude winter cover crops are feasible in Eastern Cape and recommend grazing vetch and radish.
