2024 Nitrogen Rates in Corn Trial (Producer-Led)

The project compares different nitrogen rates applied at different times in the growing season on corn yield and quality. This project was set up on a local producer’s land, southeast of Barrhead.

Corn is becoming a more popular silage option in the west central area, it is a high energy, digestible feed source. There are many corn hybrids out there that work well in our region. For this trial, PS 2320 RR was the variety used. It’s a roundup ready, dual-purpose corn, with good disease resistance. Producing optimal corn silage requires careful attention to soil fertility.  Corn harvested for silage removes more nutrients compared to grain harvest. Understanding the crop’s nutrient requirements is paramount in successful corn silage production.
