Evapotranspiration with strawberries grown in drip irrigation conditions
Evapotranspiration of a strawberry, ever-bearing variety Polka in three-year (2011- 2013) field experiments with drip irrigation on leached cinnamon forest soil in the area of Chelopechene, Sofia district. Different irrigation regimes have been tested: from fully satisfying the daily needs of the crop from water to irrigation with 20% and 40% reduced irrigation rates. During the research period, the total evapotranspiration rate for the strawberry growing season was 213 mm in average. Average 24-hour values vary by date. The highest are in the first and second ten-day period of June (harvest period).
