Global Maize Project in the United States: West Lafayette, Indiana

The objective of this study is to determine whether or not an ecological intensification (EI) approach can increase yields more quickly over time than current farmer practice. The study design is a randomized compete block design. Two management practices are investigated: 1) farmer practice (FP), and 2) EI. Three N rates are also being studied: no N, intermediate N, and full N.

The site was affected by drought in 2012 and management practices did not produce significantly different maize grain yields. Relationships between whole plant nutrient uptake and yield are currently being studied. IPNI-27
