Abstract

Di-calcium phosphate, calcium superphosphate, and precipitate phosphoric fertilizer increased wheat yields by 12.8, 17.9, and 11.3% respectively compared with the control. Using citric-dissolvable phosphate fertilizer, the wheat cultivar with a genotype of high P efficiency, Jin-87-4617, yielded 13.9% higher than the control, while the wheat cultivar with a genotype of low P efficiency, Qinmai-1, increased yield only by 2.9% compared with the control. Therefore, the efficiency of P fertilizer for Jin-87-4617 was higher than that for Qinmai-1.
