Brassica Yield Following Grazed and Un-Grazed Cover Crops

Published Dec 5, 2017

In a Nutshell

This project compares yields of fall brassica crops following a spring cover crop of oats and peas. In treatment plots spring cover was grazed by sheep; control plots were un-grazed.

Key Findings

There were no statistical differences in brassica yield by treatment (grazed vs. un-grazed cover crop). Though Black had more than 3 tons DM/ac of aboveground biomass, the sheep trampled more than they foraged because the oats were too fibrous. Black is interested in grazing more spring-seeded cover crops based on trial results; Quee plans to stay with his current system of grazing in fallow years and in the early spring and late fall.
