Performance of one potato plant as influenced by soil conditioner UGmax

Studies were carried out over the years 2008-2010 to determine the effect of Soil Conditioner UGmax on unit performance, that is potato tuber weight and number per one plant and average weight of one tuber. An experiment included two factors: I – two edible potato cultivars (Satina and Tajfun), II – five UGmax application methods (1. control without UGmax, 2. UGmax applied prior to tuber planting at the rate of 1.0 dm³ ha^-1 , 3. UGmax applied prior to tuber planting at the rate of 0.5 dm³ ha^-1 followed by two foliar applications at the rate of 0.25 dm³ ha^-1, 4. UGmax applied prior to tuber planting at the rate of 1,0 dm3 ha-1 followed by two foliar applications at the rate of 0.5 dm³ ha^-1, 5. two foliar applications of UGmax at the rate of 0.5 dm³ ha^-1). Samples, consisting of tubers of 10 potato plants, were taken to determine the performance of one plant. The Soil Fertilise UGmax increased the weight of tubers per plant and the average weight of one tuber compared with the control. Moreover, the potato cultivars and weather conditions during the growing season significantly influenced the above-mentioned parameters.
