Wplyw ekspozycji i spadku terenu na plonowanie uzytkow zielonych w warunkach gorskich

The investigations were carried out in the mountain conditions (600-640 m. esl) in Male Pieniny region in the years 1986 - 1990. The researches were realized on the fields experiments in 5 terrain points, whis were situated on the flat surface and slopes with opposite expositions as North and South. On each inclinations (10o and 20o) there were 2 field experiments. The eim of these investigation there was knowing of DM yields on die objects NPK-fertilized and non-fertilized. The results show that die higher yealds we can have on the south slope than on the north slope. Also the high a.s.l. has negative influence of the grassland yie yields (1,3-2,6%) on each degree of the inclination. It is agree with up to the present opinion in this problem.
