Treatment evaluation includes T₁: control; T₂: soil application (sulfate salt); T₃: soil application (chelated product) and T₄: foliar application (chelated product) of Cu and Zn for wheat and pea, respectively. For canola, the treatments of B are tested as- T₁: control; T₂: soil application; T₃: foliar application (one time) and T₄: foliar application (two times) using boric acid.

NS Not significant (p > 0.05), SEM Standard error of mean (n = 4).

^aBoron concentration in canola grain of Whitefox soil were not measured due to insufficient amount of grain. Treatment columns of grain and straw of each crop followed by the different letters are significantly different.
