Use of drip irrigation to reduce irrigation in potato growing in the Czech republic

Original language description

Poster. EAPR 2022, 21st Triennial Conference. Krakow, Poland. 4. - 8.7. 2022 In the 2018/2019 season. field experiments with drip irrigation took place in the Czech Republic at two locations in the Vysocina Region (Valecov 49.643145, 15.497054 and Okrouhlice 49.625860, 15.505214). In the spring of 2018, the used agrotechnical procedures of soil preparation, work Operations and other agrotechnical interventions on the established experimental plots were monitored. Measurementsof phys-ical soil properties were performed including sampling for soil analyses. Soil conditions, i.e. soil moisture and temperature in potato ridges, were being monitored starting from potato planting, during the whole Vegetation period until harvest, especially in the root System of tubers. Other monitored parameters were the air temperature, rainfall and irrigation doses at the sites were monitored. The potato variety Antonia (medium early) was used on both experimental sites. At the Okrouhlice site, half of the experimental area was irrigated and half was left without irrigation. Irrigation was controlied using Virrib soil moisture sensors. Irrigation would bestarted when the soil moisture dropped under 15% vol. At the Valecov site, the moni­tored variants were 1) without irrigation with 120 kg/ha N before planting 2) irrigation at 15% vol. and with 120 kg/ha N before planting 3) irrigation at 15% vol. and 60 kg/ha N before planting and 60 kg/ha N be­fore irrigation and 4) control variant without irrigation and without N. Irrigation regulation was controlied again by Virrib sensors. In both sites, drip hoses were installed and retrieved using burying and recoiling machine manufactured according to design by Research institute of agricultural engineering, p.r.i.The drip hose wasplaced toadepthof 5 cm from the top of the ridges and the tubers were at 15 cm. Moisture and temperature sensors TMS-3 and TMS-4 from Company TOMST (Czech Republic), were used to monitor soil moisture and temperature on the experimental site. The sensors were installed in the Upper and lower part of the ridge profile. The depths of the installations were 10 cm and 20 cm from the top of the ridge. The evaluation parameters of the quality of drip irrigation with regard to climatic conditions were the time in-tervals, frequency and the moisture in selected soil depths. From the trend of decrease in soil moisture after irrigation, it is possible to recommend lower irrigation doses around 4-5.5 mm, where the inefficient water consumption is lower than at doses higher than 6 mm.
