Abstract
Fertilizer trials with processing peas were conducted at 15 locations during a 4-year period. Although the soils varied in their chemical properties, there was no general or consistent yield response with increasing rates of N, P or K. There was, however, a consistent increase in leaf N with the higher rates of N and in leaf K with all rates of K. Increasing rates of K were accompanied by decreasing leaf levels of Ca and Mg. The results indicate that N, P and K applied at approximately 25, 50 and 25 kg/ha respectively should be generally adequate.
