Influence of organic and mineral fertilizers on agronomic traits of potato

The aim of research conducted on the experimental field of Faculty of Agriculture in Zagreb during 2012 and 2013 was to determine the influence of organic and mineral fertilizers on the agronomic properties of potato. The research comprised two organic fertilizers, Biorex and Italpollina, mineral fertilizers and a combination of mineral and organic fertilizers. The highest yield of tuber and dry matter was achieved when the fertilization was conducted using solely mineral fertilizers or a combination of mineral and organic fertilizers. Fraction 35-55 mm had the highest share in the total tuber yield. Fertilization with mineral fertilizers and with combination of mineral and organic fertilizers had a positive effect on the share of fractions ˃55 mm particularly in favorable 2012 year.
