Within the different soil/climatic zones of western Canada, determine: 1) which individual agronomic inputs contribute most to field pea seed yield, 2) which combination produces the highest seed yield and economic return, and, 3) how plant population, leaf and stem disease, crop maturity, grain yield, and quality are affected by input interactions.


It is recommended that all farmers use adequate seeding rates to target the recommended plant population to maximize field pea yield potential. Under situations where the farmer expects relatively high yields, it is also recommended to use a granular inoculant to ensure nodulation and nitrogen (N) fixation can provide sufficient levels of nitrogen to the crop. If the crop develops a thick canopy and/or disease develops, adding a foliar fungicide will protect and maintain the yield potential of the crop. It is not expected to see a yield response using starter nitrogen fertilizer, except potentially when residual N is extremely low or when there are extreme cases of late season root rot or moisture limitations which limit yield potential and nitrogen fixation.
