During the period 2009-2010, there had been investigated the specification of leaf exchange and vine production (dessert variety Velika), which maintenance of the soil surface is performed in different ways. The experimental setting consisted of variants with conventional growing plantation (usage of synthetic fertilizers Basifertil, followed by plowing and disking of row spacing), mulching of the soil surface with straw, greening up of the soil surface, fertilizing the area in row spacing with manure, followed by plowing. It was concluded, that the method of maintaining the soil surface affects the leaf gas exchange and yield of the vine. For the period of the survey, with the best parameters for leaf gas exchange and with the highest yield was characterized the vines grown under conventional type and production by fertilizing with manure row spacing. The biggest advantage of the application of manure is that the effect on soil fertility, it is also environmentally friendly solution to the protection of the environment and crop production from pollution.
