Maize is one of the most widely grown and used crops in the world. Nowadays, weather anomalies such as drought and sudden heavy rains due to climate change bring up serious challenges to maize production. One environmentally conscious approach that contributes to climate change resilience is cover cropping. In the production technology of corn-legume cover crops, corn as the cash crop was examined in two ways in a field small-plot experiment in four repetitions in randomized block design plots. In one case, the legume cover crops were sown as an interseeding cover crop in a corn monoculture; in the other case, the crop rotation agrotechnique was applied to what CCs could be included in the cereal-maize crop rotation after winter cereals. The experiment was set up in Vertisol and Chernozem. In all cases control treatment was included. Our results showed that pea vine and cowpea contributed to increased corn yield on both soil types and agrotechniques. White sweet clover cannot be recommended as a cover crop because this seemed too competitive with the cash crop. Field pea is recommended for the crop rotation agrotechnique. Trifolium species like Persian clover, red clover, and crimson clover show good adaptability to Vertisol.
