Effect of Phosphorus Fertilizers on Yield and Cadmium Content of Potato

Abstract

This study evaluated the effect of different types and rates of phosphorus fertilizers on yield and cadmium content of potato on a slightly alkaline alluvium soil. Results show that the highest yield was obtained under treatment with monoammonium phosphate (manufactured in Russia) and the lowest under Bulgarian TSP treatment. The highest total cadmium was found in potato tubers treated with Bulgarian diammonium phosphate, in contrast to the lowest measured values under Russian DAP treatment.

U radu je ispitivan uticaj različitih vrsta i doza fosfornog đubriva na prinos i sadržaj kadmijuma u krompiru, na zemljištu tipa aluvijum, slabo alkalne reakcije. Dobijeni rezultati pokazuju da je primenom monoamonijum-fosfata (poreklom iz Rusije) ostvaren najveći prinos, dok je najmanji prinos postignut sa primenom bugarstkog TSP. Najveći sadržaj ukupnog kadmijuma u krtolama krompira utvrđen je primenom bugarskog diamonijum-fosfata, a najmanji primenom ruskog DAP-a.
