Abstract
Sunflower (Helianthus annuus L.) was grown on liquid medium containing either nitrate, ammonium or ammonium + nitrate, with or without potassium. The growth of plants supplied with nitrate or ammonium + nitrate in the presence of potassium (5 mmol/1) was comparable. Plants grown on ammonium-N only showed significantly lower growth. Dry matter and organic nitrogen content in plants supplied with ammonium + nitrate (total nitrogen 10 mmol/1) in the presence.
