A study was conducted in 2016 to determine the effect of cereal rye (Secale cereale) and hairy vetch (Vicia villosa) combination on pest suppression and corn yield in Northwest Missouri. The experiments consisted of six treatments corresponding to cereal rye and hairy vetch combinations, plus a control. The corn treatments included conventional corn and transgenic corn. Harvested ears were assessed for rating on corn earworm damage and fungal damage on ears. Similarly, corn yield was measured across the treatments on randomly selected ears. Visual assessments of weed suppression, pest suppression (corn earworm damage), and fungal ear rots revealed no significant treatment effects. However, relevant trends in higher corn yield were observed with increasing hairy vetch proportion from 33% to 66% level. Delayed termination of hairy vetch caused poor corn growth and higher true armyworm (Mythimna unipuncta) infestation.
