In 2001-2004, on the ecological production farms of Mr. Stanislovas Grajauskas in Naujasodis village, Molėtai region, Mr. Marijus Čekavičius in Ramonai village, Raseiniai region, and at the Research Station of Lithuanian University of Agriculture the influence of different potassium fertilizer forms on ecologically cultivated carrot yield and quality was studied. When fertilized with potassium magnesia and potassium sulphate, the total harvest of carrots increased, and when fertilized with all potassium fertilizer forms the marketable harvest of carrot also increased essentially. Potassium fertilizer forms didn’t have substantial influence on the marketable harvest of carrots. Potassium magnesia increased the content of carotene in carrots significantly if compared with potassium chloride fertilization. Potassium fertilizers didn’t have substantial influence on the content of dry substance and reducing sugar in carrots. Under the effect of potassium magnesia and potassium sulphate, the content of nitrates in carrots decreased essentially if compared with potassium chloride fertilization.
