A Corn Variety Trial was conducted in 2017 to evaluate the performance of several varieties and their potential in the west-central region of Alberta. Four varieties were tested at the Wildwood Forage Research Site.
Corn is a high energy feed with protein levels that will normally match the nutritional needs of a dry cow in mid and late pregnancy. It also has the potential to produce more dry matter than tame hay or forage cereals. By replacing other forms of feed with standing corn, labour time and machinery use, associated costs are reduced as no summer feed harvesting is required and winter supplemental feeding is limited.
To evaluate four different corn varieties for maturity, quality and yield grown. To demonstrate the different varieties that can grow in the west-central area. To make recommendations to beef cattle producers in the area that intend to winter feed their cattle with standing corn.
2017 Trial Summary
This Corn Variety Trial was conducted in 2017 to evaluate the performance of several varieties and their potential in the west-central region of Alberta. Four varieties were tested at the Wildwood Forage Research Site (SE 27-53-09- W5).
Varieties used were:
Plots were seeded to a prepared seed bed on May 31, 2017 with a John Deere corn planter (20m long, 12 rows at 30in spacing). All varieties, aside from CM440 Conventional, were seeded at a rate of 30,000 seeds per acre. CM440 Conventional was seeded at a rate of 62,000 seeds per acre.
Glyphosate treatments were applied prior to seeding and when the plants reached the three leaf stage for all varieties, aside from CM440 Conventional. CM440 Conventional received 2,4D Ester 700+DualII Magnum and MCPA Amine 600.
Plant counts and yield data were collected September 27, 2018. Samples were also sent to A&L Canada for quality analysis.
