Abstract:Pri poskusu, ki je potekal v letu 2011 na Univerzitetnem kmetijskem centru Pohorski dvor, na posestvu Fakultete za kmetijstvo in biosistemske vede v Pivoli, smo pri jablanah sorte 'Gala' ugotavljali odzivnost sorte na gnojenje z dušikom mineralnega in organskega izvora. Aplicirali smo tri mineralna gnojila: KAN, Urea in Apneni dušik ter gnojili Biosol in Plantella Organik, ki sta organskega izvora. Uporabili smo dva različna odmerka dušika: 60 kg N/ha ter 120 kg N/ha. Za primerjavo smo imeli parcelo brez dodanih dušikovih gnojil. Ugotovili smo, da gnojenje z dušikovimi gnojili vpliva na povečanje bujnosti rasti in da ta korelira z odmerkom dušika (predvsem mineralnega izvora), kar pa ni podatek, ki bi ga potrdili za količino pridelka. V poskusu smo potrdili tudi pozitivni vpliv dušika na zmanjšanje pojava izmenične rodnosti jablan. Dokazali smo, da lahko organska gnojila nadomestijo mineralna gnojila, brez vidnih posledic za količino in kakovost pridelka.

Title:INFLUENCE OF DIFFERENT SOURCE AND DOSAGE OF NITROGEN ON GROWTH AND YIELD OF APPLE TREES
Abstract:In an experiment that was set up in 2011, at the University Agricultural Centre (UAC) Pohorski dvor, which is part of the Faculty of Agriculture and Life Sciences at the University of Maribor, we were determining the response of cv. ‘Gala’ apple trees as regards to fertilising with nitrogen of mineral or organic origin. We used three mineral fertilizers (KAN, Urea and calcium cyanimide) and two organic fertilizers (Biosol and Plantella Organik), which were applied in two different dosages (60 kg N/ha and 120 kg N/ha). Our control group consisted of trees that were not treated with nitrogen in any form. The results showed that fertilizing with nitrogen (mineral or organic) increases the growth of trees in correlation with the applied dosage of nitrogen (particularly of mineral origin); however, the same cannot be said about yield quantity. The experiment also confirmed nitrogen's positive effect on reducing the alternate bearing of apple trees. With the experiment, we established that organic fertilizers may substitute mineral fertilizers with no visible consequences to yield quantity or quality.
