Abstract:	Načrtno gnojenje krompirja na podlagi analiz postaja edina priporočena praksa. Na posestvu UKC Pohorski dvor Maribor smo izvedli enoletni poskus po naključnem bloku v štirih ponovitvah. Poskus je vključeval pet sort krompirja 'Carlingford', 'Frisia', 'Desiree', 'Romano' in 'Cvetnik' in tri različne ciljne vrednosti dušika: 133, 153 in 173 kg N ha-1. Za kontrolno obravnavanje smo pri vsaki sorti uporabili obravnavanje brez dodanega dušika (0 kg N ha-1). Med rastno dobo krompirja je bil analiziran indeks listne površine, višina rastline in število stebel na posameznem obravnavanju. Ob spravilu smo pridelek gomoljev stehtali in sortirali po debelini na drobne, srednje debele in debele gomolje. Ciljna vrednost 173 kg N ha-1 ima statistično značilen vpliv na pridelek krompirja (31,0 kg 10 m-2), med posameznimi ciljnimi vrednostmi N pa ni razlik (obravnavanje 133 in 153 N, pridelek 25,4 in 24,6 kg 10 m-2 ). Pri morfoloških lastnostih je največji indeks listne površine dosežen pri obravnavanju 173 kg N ha-1 (2,7). Na višino rastlin in število stebel imata sorti in ciljne vrednosti statistično značilen vpliv. Največja višina je dosežena pri sorti 'Carlingford' (64,3 cm) in pri obravnavanju 153 kg N ha-1 (58,1cm), največje število stebel pa pri sorti 'Desiree' (4,9) in pri obravnavanju 173 kg N ha-1 (5,0).

Title:	The Effect of Nitrogen on Growth and Crops of Different Potato Varieties (Solanum tuberosum L.)
Abstract:	Systematic fertilization of potato on the basis of analysis becomes the only recommended practice. We performed an one-year experiment in randomized block system with four repetitions at the estate of the University of Agriculture Centre Pohorski dvor (UKC). The experiment included five varieties of potatoes: 'Carlingford', 'Frisia', 'Desiree', 'Romano' and 'Cvetnik' and three different target levels of nitrogen in the soil: 133, 153, 173 kg N ha-1. For the control treatment no nitrogen was added to the soil for each individual variety (0 kg N ha-1). During the growing season of potatoes, we analyzed the leaf area index, plant height and the number of stems in a particular test area. At harvest, the tuber crops were weigted and sorted according to the thickness into small, medium, and large tubers. The target value of 173 kg N ha-1 had a significant impact on the potato yield (31.0 kg 10 m-2), while there was no difference between the target values of treatment 133 N and 153 N, which resulted in the yield of 25,4 and 24,6 kg 10 m-2. In the morphological characteristics, the largest leaf area index is achieved in the treatment of 173 kg N ha-1 (2.7). The variety and the target value have had a significant impact on the plant height and the number of stems. The maximum height was achieved in the variety 'Carlingford' (64.3cm) and by applying the treatment of 153 kg N ha-1(58.1), the largest number of stems was achieved in the 'Desiree' variety (4.9) and by applying the treatment of 173 kg N ha-1 (5.0).
