The purpose was to assess the effect of sowing rate and variety on the nutrient content of field peas. The varieties were: Bruno, Capella, Clara, Kirke, Onward, Vitra. Treatments: sowing rate of 120 seeds per m2 for all varieties; sowing rate of 144 seeds per m2 for all varieties. Increased sowing rate made followed changes: increased the content of Nitrogen in varieties Bruno, Kirke and Onward; increased the content of Phosphorus in all varieties in 2015, while only in varieties Clara and Onward in 2016; decreased the content of Potassium in varieties Bruno, Kirke and Vitra in 2016; decreased the content of Calcium in variety Bruno; decreased the content of Magnesium in variety Kirke in 2015 and in varieties Onward and Vitra in 2016. The highest contents of Nitrogen, Potassium and Calcium were in variety Onward. In 2015, the highest content of Phosphorus was in variety Onward, while in 2016 the highest content was in variety Bruno. The highest content of Magnesium was in varieties Bruno, Onward and Vitra. Increased sowing rate did not have a constant influence on the nutrient content of field peas. We can recommend to grow variety Onward, as the variety with high nutrient content.
