Abstract

The researches were carried aut during 1976-2012 in the field for soil water balance study placed on the preluvosoil from Agricultural Research and Development Station Oradea. The irrigation was needed. The irrigation was needed every year becouse on the watering depth (0-75 cm) decreased bellow easily available water content every year and pedological drought was presented. In 26% from year studied the strong pedological drought was presented in unirrigated potato.The use of the irrigation improved the potato microclimate and the value of the report water/temperature light (Domuţa climate index) increased with 58% in the period April-August; the biggest difference in comparison with unirrigated variant was registered in July. Daily water consumption increased in the irrigated variant and the biggest relative difference was registered in August (57%). As consequence the value of the total water consumption increased with 38.3% in comparison with unirrigated variant, variation interval: 13-129.1%. Along the year, the irrigation participation in the covering sources of the total water consumption was between 7.1% and 61.1%. Irrigation determined an average yield gain of 61.8%, the improve of the yield stability and a bigger percentage of the big tuberous in the yield, 84.4% vs 75.6%. The average value of the water use efficiency was bigger in the irrigated variant (7.06 kg/m3 vs 6.03 kg/m3). Irrigation water use efficiency was of 7.84 kg yield gain/m3 irrigation water.

Keywords: potato, irrigation, pedological drought, water consumption, yield gain, water use efficiency
