We conducted on-farm trials in the southern Guinea savannah of Ghana in 2016 and 2017 to evaluate soyabean response to three fertiliser blends to guide farmers towards profitable adoption of appropriate phosphorus fertiliser blend for improved soyabean production. Old Yara Legume, New Yara Legume and Triple Superphosphate fertiliser blends were evaluated. In both years, the phosphorus fertiliser blends were evaluated in a Randomised Complete Block Design with 20, 30, and 40 kg P ha⁻¹ application rates together with control. Phosphorus fertiliser application increased soyabean yields by 1 070 kg ha⁻¹. In 2016, fertiliser blend use efficiency ranged from 2.9 kg grain per kg fertiliser blend applied with the New Yara Legume applied at 40 kg P ha⁻¹ to 7.4 kg grain per kg fertiliser blend applied with the Triple Superphosphate applied at 40 kg P ha⁻¹ with significant differences between treatments. In 2017 …
