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.
