Kansas Agricultural Experiment Station Research Reports

A long-term cover crop experiment was established in 2007 at Ashland Bottoms near Manhattan, KS, to determine the effect of cover crops and nitrogen (N) rates on subse­quent corn growth and yield in a wheat-corn-soybean rotation. Treatments included chemical fallow, double crop soybean, different cover crops (cereal rye,crimson clover, a mix of cereal rye and crimson clover, and a diverse mix of seven species) planted in late summer after wheat harvest, and five N rates (0, 40, 80, 160, and 240 lb/acre) applied to the subsequent corn crop. Yield responded differently to N rate depending on cover crop …
