The effect of covering rows of early potatoes with non-woven fleece on tuber yield, dry matter content, soil and air temperatures was investigated during the years 1999-2003. In comparison with uncovered soil, the covering enhanced the yields in average by 35.8% - tubers harvested 60 days after planting, and by 17.2% - tubers harvested 67 days after planting. The difference became non-significant in potatoes harvested 85 days after planting. The yield effect of the fleece was affected by year (higher effect in the years with cold spring) and by variety (Impala responded at 60 days after planting by yield increase under fleece of 43.7%, Adora of 27.9%). Higher dry matter content of tubers by 0.87% was found in covered plants 60 days after planting in comparison with control. Fleece covering enhanced the average air temperature in the ground layer by 2.0 deg C, in the soil by 1.8 deg C (at 100 mm of depth).
