In-Furrow Amendments

Four different in-furrow Alpine fertilizers were applied to CS 2000 RR canola plots and the yields analyzed. In-furrow applications coincided with seeding, treatments included: G22 – 20 L/ac, F18 Max – 0.5 L/ac, K20-S – 4 L/ac, K24 – 4 L/ac, and urea in furrow – 32.61 lb/ac.

F18 Max in-furrow fertilizer led to the greatest canola yield relative to the other products used in the trial (P=0.002). For said treatment, yield was 4.7 bu/acre. Untreated, K20-S, and G22 treatments led to similar yields, all between 2.4-3.3 bu/acre. The lowest yielding canola was that subject to K24 fertilizer, producing 2.1 bu/acre.

Foliar Amendments

Five foliar Alpine fertilizers were applied to CS 2000 RR canola plots and the yields measured. Foliar applications were carried out on June 5. Fertilizer treatments in this experiment were: F18 Max – 2 L/ac, 6-20-3-1S – 20 L/ac, 6-20-3 – 20 L/ac, 7-21-3-1S – 20 L/ac., and Microbolt (Mo) – 18 g/ac.

There were no significant differences in canola yield regardless of the foliar-applied fertilizer used (P=0.16). The yield values ranged from 1.25 bu/acre to 5 bu/acre. The coefficient of variation is 60.5, indicating that values contributing to the means were highly dispersed, likely due to weather-induced stress throughout this wet season.
