Abstract. During the period of 2013 – 2015 the influence of farming types (organic and biodinamic) on the phytosanitary status and yield of kamut was studied. Kamut is resistant to diseases and they are not a problem for growing it in an organic and biodynamic way. In both kinds of farming single numbers of five types of pests on kamut were recorded. Two of them were from Order Homoptera (Sitobion avenae L. and Rhopalosiphum maidis (Fitch)) and three from Hemiptera (Philaenus spumarius (L.), Eurygaster integriceps Put. and Aelia acuminata L.).The species diversity of the weeds was greater in biodynamic farming. Kamut yield from biodynamic farming was proven to exceed the organic one. The strength of effect of the type of farming factor was 83.57%.
