Interaction of fertilizer N and P and snow conservation on yield of spring and winter wheat in Southwestern Saskatchewan

This project evaluated the effect of N and P fertilization on wheat yield responsiveness to snow trapping for moisture conservation, in semi-arid south west Saskatchewan.

Objectives

      1. To determine advantage in stored soil water that can be expected from leaving strips of tall cereal stubble to trap snow as compared to stubble cut at one uniform, short height (standard practice).
      2. To determine the optimum rate, method and time of application of N for spring wheat production under conditions of improved snow management and zero-tillage.
      3. To determine the optimum rate of P application for spring wheat production under conditions of improved snow management and zero-tillage.
      4. To determine the maximum yield achievable for spring wheat under dryland culture.
      5. To determine whether zero-tillage, snow trapping and various fertilizer treatments are economically feasible in southwestern Saskatchewan.
      6. To determine effect of zero-tillage on soil quality.
