Options of potato production stabilization using drip irrigation in the potato production region of the Czech Republic

Original language description

The aim of the trials was verification of drip irrigation using under conditions of the potato production region of the Czech Republic. The verification was performed with exact field trials on the land of Potato Research Institute Havlíčkův Brod (460 m a.s.l., cambisol, annual mean air temperature 7 °C, annual mean total precipitation 652 mm). The trials were performed with two potato varieties, very early Monika and medium-early Jolana between 2016 and 2017. Irrigation pipes were installed after planting into ridges (4.5 cm below the ridge top). Irrigation was automatically started based on soil moisture measured with moisture sensors. Three variants of irrigation intensity were evaluated, started at various soil moistures – 15 % (low), 20 % (intermediate) and 25 % (high). Uniform irrigation rate was 10 mm. Compared to non-irrigated control a statistically significant potato yield increase was found almost in all cases. For high irrigation intensity the yield was 47.5 % (Jolana) and 49,3 % (Monika) increased in 2016 and 33.1 and 59 % increased in 2017 due to drip irrigation. Drip irrigation also significantly increased marketable potato yields in both years. On the other quality parameters any negative effect of irrigation was not detected. Based on the results we could conclude that using of drip irrigation could stabilize potato production also in regions, where irrigation has not been applied so far.
