EFFECT OF MULCHING AND NITROGEN FERTILIZATION UPON GROWTH AND YIELD OF LINGONBERRIES (VACCINIUM VITIS-IDEA L. ). PART II.

K. Pliszka, K. Scibisz
In 1981 lingonberry ( cowberry ) rootings cv. " Koralle " were planted on strongly acid, podzolic sandy soil, low in P,K and Mg. Four types of mulching: peat-moss, pine bark, litter of pine needles and sand, comparing with clean cultivated control, and two levels of nitrogen ( 0 and 60 kg/ha ) were applied, in split-plot factorial design. After six years of the trial, the best plant growth and survival were observed on the plots with pine bark mulching. Plants were not injured after the severe winter 1986/87. In two consecutive years the highest yield of berries was recorded in the pine bark treatment. There was no effect on number of berries per cluster and percentage of fruit set. Nitrogen fertilization has affected increase in berry yield only on the plots with pine bark mulching. In another treatments there was no effect of nitrogen upon the yield. Leaf Ca and Mg content were high and N was low from plants in the pine bark treatment. In can be suggested that pine bark mulch has affected better plant growth and cropping. Nitrogen requirements of lingonberries is rather low.
