Integrating livestock and cropping systems: Interseeding cereal rye into corn for grazing.

ABSTRACT: Interseeding annual forages into growing corn may be an alternative for both cover and grazing in temperate regions of the United States. A 4-year experiment evaluated the effect of interseeding cereal rye (Secale cereale) into corn for grazing after harvest on corn grain, forage biomass yield and quality, soil health, and estimated spatial biomass yields using vegetation indices (VIs) from multispectral imagery collected from an unmanned aircraft system platform. Corn was planted (79,074 plants ha^-1) each spring on two 4.8-ha sites in central Pennsylvania. Cereal rye was interseeded (135 kg ha^-1) into corn at the V4-V6 stage. Corn was harvested as grain in November, and each site was subdivided and randomly assigned to grazed or non-grazed treatments. Biomass yield a
