Evaluation of Organic Wheat and Hybrid Rye Varieties at the Neely-Kinyon Memorial Research Farm, Greenfield, IA, 2025

Abstract

There were five varieties of wheat and one hybrid rye variety selected for the 2025 small grain trial. These included the following varieties: three hard red winter wheat varieties: SD Midland and Blue River 211 (Albert Lea Seed, Albert Lea, MN), and Washington State University Bread Lab’s “Climate Blend.” In addition, two hard red spring wheat varieties: Bolles and Glenn (Albert Lea Seed, Albert Lea, MN) were evaluated. Lastly, ‘Serafino’ hybrid rye (Albert Lea Seed, Albert Lea, MN) was also evaluated. Plots measuring 20 x 40 ft. were laid out in a randomized complete block design with three replications of each variety. Winter wheat were planted at 100 lbs/acre and hybrid rye at 70 lbs/acre on September 27, 2024. Medium red clover was frost-seeded on March 13, 2025, at 16 lbs/acre. Spring wheat was planted at 120 lbs/acre on March 13, 2025. Wheat and rye plant height and biomass were measured on May 5, 2025. Leaf biomass was sampled by cutting at the soil surface in a randomly selected square-foot area in each plot. Wheat and rye were harvested by combine on August 4, 2025.
