Abstract

The frequent occurrence of years with extreme drought leads to the investigation of measures for mitigation of their impacts. The efficiency of organic mulch materials - straw and compost application as the preservation of potato production in drought conditions were verified in this study. Three mulching treatments were verified during the three experimental years (2016-2018) in an exact field trial with potatoes cv. Dicolora. Wheat straw mulch in the rate of 2.5 t/ha (SM1) and 4.5 t/ha (SM2), compost in the rate of 20 t/ha (CM), and control block without any treatments (C) were used. The yield of marketable tubers (tuber over 40 mm) showed a significant increase by 21.2% at the straw mulch treatment (SM2) in comparison with control. As for the straw mulch (SM1) and compost mulch (CM), tubers yields increased by 12.8% and 10.1%, respectively, compared to control.
