Project Title:
Locus Ag Industry Trial in Spring Canola
Objective:
To test different Locus Ag treatments for quality and yield for canola.
Personnel:
J.A. Torrion, Daniel Porter
Summary:
Invigor canola was planted with the four Locus seed treatments and a grower practice as a check on April 29, 2022 (see respective management Tables 1 and 2 for details). The seeding rate was 4.5 lbs/Ac targeting 10 seeds/ft2 at a 0.99% germination rate based on the germination test. The trial was under a randomized complete block design with four replications. Each plot was separated by a buffer plot to ensure spatial separation between individual treatment plots.
Two environments were tested under Creston Silt Loam with subsurface recharge (Study 1, high moisture) and Creston silt loam without subsurface recharge (Study 2, low moisture). Subsurface recharge is evident in Study 1 location with historical yield and soil moisture sensor data over the years. The management table is shown in Table 1.
In study 1 (Table 3), only the thousand kernel weights were significant where ‘Code T T’ treatment had a smaller seed size than the other treatments. ‘Code B T T’ had the largest seed size. All of the treatments had the same yield as well as the rest of the agronomic performance. In study 2 (Table 4), no significant differences were observed in all parameters gathered.
