Winter Pea Cover Crop as a N Management Tool in Ohio.

A three-year study was conducted at the Western Agricultural Research Station to evaluate the contribution of nitrogen from fall planted winter pea in Ohio. Winter pea was planted at two time periods and compared to a wheat stubble check. Corn was planted by no till at three nitrogen levels with and without planter nitrogen.

Insect and rodent pests reduced corn stands in some years in the late planted winter pea. Early planted pea stubble provided an excellent stubble for planting for no till corn. While there was some rotation benefit to winter pea, little response was shown for nitrogen supply.

Other treatments trialed as a possible cover for no till corn and nitrogen management were annual ryegrass and soybean.
