In the years 1977-79 field experiments were carried out where influence of phosphorus and potassium fertilization on the yield of some varieties of field pea, blue lupine, white lupine and field bean were researched. Under field pea and blue lupine following mineral fertilizers were applied: P80K160 and P120K240 kg/ha and under white lupine and field bean P120K160 and P180K240 kg/ha. Higher levels of mineral fertilization caused significant increasing of yields of seeds and straw of all investigated species. Higher level of mineral fertilization caused increasing of protein content in the seeds of field bean and blue lupine, variety Ignis.
