Title
INFLUENCE OF HERBICIDE USE AND INTER-ROW TILLAGE ON CORN YIELDS AND SOIL CONDITIONS
D. R. COOTE; W. J. SAIDAK Canadian Journal of Plant Science 1984. doi:10.4141/cjps84-058
Other claims from this paper (6)
- Intervention effect Grain corn yields were significantly increased by inter-row tillage.
- Intervention effect In a subset of corn plots, surface soil bulk density was lower after tillage.
- Intervention effect In a subset of corn plots, air-filled porosity was higher after tillage.
- Intervention effect Soil bulk densities were decreased in September by a possible interaction between inter-row tillage and herbicide use.
- Association Grain corn yields were positively correlated with soil moisture in September.
- Mechanism The authors suggest that some of the corn yield improvement from tillage resulted from better soil physical conditions.
