Investigating Hybrid Interactions with Nitrogen and Foliar Fungicides

IPNI-2012-CAN-ON32

Research Questions: Does the response to N depend on plant population and hybrid (or phenotypic traits)? Does the response to nitrogen depend on whether a foliar fungicide was applied at tasseling, and does this response depend on the hybrid (or phenotypic traits)? Does the response to nitrogen depend on whether Acapela was applied in a high population? When yields were affected by nitrogen, plant population, and foliar fungicides what were the main physiological and yield components affected?. Read more

Interpretive Summary

Farmers recognize that corn hybrids can differ in their response to nitrogen (N) fertilizer applications. This study was conducted to investigate such differences among six soon-to-be-released experimental hybrids from two major seed companies. The trial was conducted in Ridgetown, Ontario from 2012 through 2014. The hybrids were compared at two plant densities (32,000 and 42,000 plants/A) with and without an added fungicide.

This study was conducted to investigate such differences among six soon-to-be-released experimental hybrids from two major seed companies. In the 2012 field trial in Ridgetown, Ontario, Canada, hybrids showed large differences in response to N and plant density and their interactions, but little response to fungicides.
