To evaluate intercropping potential for canola and cover crops.

Canola is quite susceptible to water logging and shows a yield reduction if exposed to excess moisture in the earlier phase of crop growth. Wet soils cause an oxygen deficiency, which reduces root respiration and growth. This reduces nutrient uptake, and if conditions persist, plants can die or prematurely senesce (Canola Council of Canada). With wet conditions, roots may be shallow and not able to access nutrients once the soils begin to dry. A few days in waterlogged soil can be enough to kill canola plants, and yield loss is certain — although as canola plants age, they tend to be more resilient. The current study was designed with the objective to determine if canola variety agronomic attributes (maturity and height) and seeding rate can be used to dictate canola yield and performance under excess moisture conditions. Three canola varieties and three seeding rate combinations were evaluated under excess moisture and ideal growing (on tile drainage land) conditions.

1. To determine if pea-canola intercrop out-yields and is more profitable than monocrop peas or canola. 2. To determine if fungicide application is a possible best management practice for disease control 3. To determine the effect of relay cropping alfalfa in pea-canola stands

To determine if organic acid products (MX-3, VX-8) have any effect on crop productivity in Canola-Soybeans crop rotation. This was the second year of evaluation and these products were applied to soybean crop.

The current project is planned to determine if efficacy of post emergence herbicides and crop fertilizers can be enhanced when used in conjunction with organic acid products. This project is evaluating the effects of organic acid products (MX-3, VX-8) on Canola-Soybeans crop rotation.

The main objective of this research is to assess the impact of tile drainage (15’, 30’ and 45’ wide) and water table management on yield and quality of canola, soybean, and wheat. The data collected from this research will be used to develop computer models that can simulate tile drainage operation under different rainfall patterns, thus extending the usefulness of this research beyond the three-year period.

The purpose of this project is - 1) To quantify the tolerance and recovery of current cultivars of canola to excess moisture stress, with the intention of identifying a cultivar that has improved tolerance. 2) To find out how timing of excess moisture stress affects yield.

Canola plots were flooded at the early and late crop stages to assess the effects of flooding on crop growth and yield. Plots were also grown under non-flooding conditions for comparisons
