ABSTRACT


Utilization of multi-cutting grass is connected with multiple passes of equipment what involve deleterious effect on the growth of plants and results in decrease the productivity. A three year study was conducted on silty loam Mollic Fluvisol covered by Dactylis glomerata. The multiple passes (2, 4 and 6) were applied in comparison with untreated object. Height of plants was measured once a week and dry matter yields were established three times a year. The obtained results indicated that the regrowth of Dactylis glomerata consisted of three phases differ in their growth dynamic. The tractor traffic affected the speed of growth in adversely proportion to number of passes. However, this effect was significantly determined only during the first phase of growth. The growth moderation of Dactylis glomerata according to tractor traffic results in decrease in DM yields. DM production decreased according to an increase in number of tractor passes.

Key words: Dactylis glomerata, height, yields, tractor traffic.
