Effect of Planting Patterns and Inter-row Cultivation on Competition Between Corn (Zea mays) and Late Emerging Weeds

Stephen D. Murphy; Yussif Yakubu; Stephan F. Weise; et al. Weed Science 1996. doi:10.1017/s0043174500094844

Other claims from this paper (9)

Intervention effect Higher corn density or narrower rows significantly increased corn leaf area index.
Intervention effect Higher corn density or narrower rows reduced the photosynthetic photon flux density available to the weed mixture below the corn canopy.
Intervention effect Narrower rows and higher corn density significantly reduced the biomass of late-emerging weeds.
Intervention effect Corn yield increased significantly by 10 to 15% only when narrower rows were used.
Intervention effect Intraspecific competition at the higher corn density significantly reduced early corn growth and offset the yield gain from reduced weed competition.
Intervention effect Increased corn density had no net yield benefit.
Intervention effect Interrow cultivation did not decrease the biomass of late-emerging weeds compared with plots where they grew uncontrolled.
Recommendation The authors recommend narrower corn row widths to reduce weed competition and increase corn yield.
Recommendation Early-season weed management is crucial, because later-emerging weeds were less important for yield.
