Favorable Weather

In the North Central USA, intersowing cover crops into standing maize (Zea mays L.) is required to establish plants large enough to afford the benefits of a cover since there is limited favorable weather for cover crop growth after maize harvest. The objective of this study was to quantify the impacts of the planting method and time of planting of three cover crop species when grown with or without maize competition on their establishment. Experiments were conducted in three environments during 2018 and 2019. Experiments consisted of a factorial combination of timing of cover crop planting (V7 and R4 growth stage of maize), cover crop species (camelina (Camelina sativa (L.) Crantz), rye (Secale cereale L.), or radish (Raphanus sativus L.), method of sowing (drilled or broadcast), and maize removal. Initial cover crop populations were similar regardless of maize removal or stage of maize when sown, but intersown cover crops produced only 3% of the fall biomass, compared with treatments with maize-removed when sown at the V7 stage of maize and 14% when sown at the R4 stage. Limited light intensity (less than 20%) under the maize canopy was the main factor affecting interseeded cover crop development. Radish was more sensitive to shading than the other cover crops. 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.

Dry Soil

In Ontario, corn (Zea mays L.) yields with zero tillage are 10–15% lower than those with conventional tillage. Slower growth with zero tillage usually begins at the four-or five-leaf stage and continues until the 10- to 12-leaf stage. We hypothesized that restriction of nodal root development occurs with zero tillage and causes the reductions in shoot growth and final yield. Two greenhouse experiments were conducted in which nodal root development of corn plants was restricted by soil compaction or dry soil while the seminal roots grew in flowing nutrient culture. Compaction reduced nodal root length by 54%, and dry soil reduced it by 90% at the 10-leaf stage. Shoot dry weight at the 12-leaf stage was significantly reduced by dry soil but not by compaction. Leaf water potential and stomatal conductance at the 12-leaf stage were reduced by dry soil despite a negligible drop in pressure potential across the mesocotyl. Dry soil reduced shoot growth in terms of plant height after the eight-leaf stage. It was concluded that restriction of nodal root growth in zero tillage systems probably would not account for the reduced yields.
