Factors Affecting the Establishment and Growth of Cover Crops Intersown into Maize (Zea mays L.) - Mattie B. Schmitt, Marisol Berti, Dulan Samarappuli and Joel K. Ransom – Agronomy 2021

The objective of this study was to quantify the impacts of the planting method and time of planting of three cover crop species (winter camelina, rye, or radish) when grown with or without maize competition on their establishment. Initial cover crop populations were similar regardless of maize removal or stage of maize when sown. Cover crops tended to establish better when mechanically incorporated than when broadcast, and the small-seeded camelina tended to establish better than radish or rye when broadcast. Camelina and rye sown at the R4 stage of corn produced similar spring biomass as earlier-sown cover crops. Intersown cover crops had no negative effect on maize grain yield.
