【 摘 要 】

The purpose of this research was to determine the water needs and results of drip irrigation of mid-early potato cultivar Courage. Studies were carried out in central Poland in 2011–2013 on very light soil. The experiment was designed as two-factorial trials with four replications. The first factor was drip irrigation: O = control (without irrigation), D = drip irrigation. The second factor was the nitrogen fertilization method: P = broadcasting, F = drip fertigation. Nitrogen fertilization was 120 kg N ha⁻¹ on each plot. Crop coefficients for irrigation period were 0.4 in June and 0.6 in July and August. According to calculations based on the crop coefficients and correction coefficients acc. Hargreaves^DA model the water requirement of potato for June–August was 202 mm. Drip irrigation increased the marketable tuber yield by 55%. Irrigation water use efficiency increased from 257 kg ha⁻¹ mm⁻¹ in D + P to 264 kg ha⁻¹ mm⁻¹ in D + F. The productivity of 1 kg of nitrogen fertilization was 189 kg ha⁻¹ in control non-irrigated plots and 321 kg ha⁻¹ in drip-irrigated plots, and it rose up to 337 kg ha⁻¹ when fertilization was applied by fertigation.
