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.
Six of the eight intercrops were shown to yield more as an intercrop than as monocrops sown separately across an equivalent area of land. These mixes included faba bean and wheat, barley and peas, oats and peas, oats and crimson clover, wheat and red clover, and barley and red lentils. As seen from the yield graph below, peas did not emerge in this year’s intercrop trial, nor did canola due to excess moisture. The C.V. value corresponding with the yield analysis is 60.3, thus results should not be considered reliable.
The Nuseed canola demonstration trial was conducted to assess the differences between several canola varieties in terms of vigour, time to flowering, lodging, shattering, and yield.
Yield from each crop was different across all intercropping combinations (P≤0.0001). Pulses such as faba bean intersown with wheat and field pea intersown in barley and in canola reported the lowest yields. Barley intersown in both lentil and field pea, respectively, was higher yielding than other cereals such as oat, wheat and other types of main crops such as flax and canola. The North Peace weather is characterized for its long dry periods, where rains could turn out once a month and extensive heat can stress and jeopardize grain quality of main crops. It is also characterized for its soils with heavy clay, where moisture from rain periods can last for days and excess water is unable to filter through. Pulses require plenty of rain and soil moisture in order to produce competent yields. It is possible the dry periods occurring in the summer season compromised pulse yields while cereals were able to manage heat stress.
Number of insects per plot varied across weeks (P≤0.0001) and across intercrop combinations (P=0.0002). The interaction between weeks and intercropping combinations was the same (P=0.3690). The greatest number of insects was reported on the first week of August whereas the lowest was June 24, which coincided with a period of extreme heat and drought. Canola and field pea intercropping combination had the lowest number of insects compared to the rest of the combinations where numbers were statistically the same.
Crystal Green is a fertilizer of continuous release made by Ostara. This fertilizer acts by releasing nitrogen, phosphorus and magnesium upon expel of root exudated citrates. Since fertilizer dissemination is modulated by components released from roots, run-off and leaching is minimized. The extent of its benefits in different crops is yet unknown. Thus, Crystal Green was tested in oilseed, pulse and cereal crops in order to observe which formulation improves yield in each of these crop types.
