Abstract
To meet the increasing demand for canola yield, prairie producers apply phosphorus (P) fertilizer to supply sufficient P for the current crop. However, the current maximum safe rate of seed-placed P for Saskatchewan are one configuration, which is 1-inch opener and 9-inch row spacing. There are evidences that greater opener spread can result in an increased maximum safe rate. The objective of this experiment is to evaluate how P fertilizer form (MAP vs Struvite), rate, and opener spread affects emergence, early biomass yield, and P uptake by canola, wheat and pea grown in rotational sequence in controlled environment conditions
