Validation of seed-placed ammonium sulphate and monoammonium phosphate on hybrid canola plant stand, yield and economics in Northern Alberta

Project Details

Status: Completed
Investment: $34,000
Commodity: Canola
Organization: Mackenzie Applied Research Association

a) The emergence of seedlings: We saw that when AS and MAP were positioned close to the seed, the emergence was higher with a combination of 20 AS & 15 MAP and began to decrease as the rate of AS grew further while MAP stayed at 15 kg ha-1. Because of the weaker emergence caused by the higher concentration of AS, canola seeds are more susceptible to AS than MAP.

b) Yield: In both years, there was a substantial (P<0.01) decrease in yield when the dose of AS was increased from 0 to 40 kg ha-1. This suggests that when employed alone, AS had a negative correlation with the average plot yield. Conversely, it was discovered that the MAP had a beneficial impact.
