Investigating Hybrid Interactions with Nitrogen and Foliar Fungicides

IPNI-2010-CAN-ON30

Brief Methods: 3 Locations (Ridgetown, Belmont, Exeter) x 2 years . Experimental Design: Split-Strip Plot with 4 replications . Main plot: 5 nitrogen rates (0, 45, 90, 135, and 180 kg N/ha) . Split plot: 12 hybrids – same hybrids all 3 locs [i. e. , single trait (GT) vs stacked; disease tol vs sus] . Split-Strip: 3 Fungicide applied at VT-R1 (UTC, Headline, Proline) . Total plots per location: 720 . Read more

Interpretive Summary

2011

Corn Hybrid Interactions with Nitrogen and Foliar Fungicides, 2011 Growers have shown interest in corn hybrid differences in response to applications of fungicide and N. Fungicides can potentially improve N use efficiency by delaying leaf senescence and enhancing the “stay-green” physiological mechanism. This project aims to determine the potential for yield improvement through exploitation of hybrid-fungicide-N interactions.
