“…According to study published by Maruyama et al [19] and Rolbiecki et al [21,22,27] the irrigation of the watermelon plants is especially important when the cultivation is carried out on a very light and sandy soil. Drip irrigation on a very light soil also has a positive effect on marketable yields of other vegetable species, such as zucchini, lettuce, radish and asparagus [28][29][30]. The yield of watermelon fruits measured in the present experiment during the years 2012-2015 was similar to those in other studies.…”

The effect of nitrogen fertigation of two watermelon cultivars grown on the very light soil in the central part of Poland, during 2012–2014, was evaluated. The field experimental design was a split-plot with four replications. The main plot was the drip fertigation with nitrogen applied in two combinations: drip irrigation + broadcasted nitrogen fertilization (DI) used as a control, and drip irrigation + fertigation with nitrogen (DF); where, two cultivars: Bingo and Sugar Baby were used as a split-plot. The phosphorus and potassium fertilizers were applied pre plant in the spring, whereas, three rates of 40 kg ha−1 of nitrogen fertilizer were applied during the growing season. The fertigation was performed using a proportional mixing dispenser. The ripened fruits were harvested progressively as they mature. The marketable fruit yield, the single fruit weight and the number of fruits per plant, were evaluated. Tested factors presented a significant effect in the yield characteristics, further the interaction among the factors was important. DF, comparing to DI, notably improved fruit traits. Bingo cultivar had higher yield than Sugar Baby, but Sugar Baby cultivar produced more fruits than the Bingo under the DF treatment. This study provides the evidence that on a very light soil with low water and nutrients retention capacity the performance of watermelon can be optimized when nitrogen is applied directly through drip irrigation.

“…At the same time, it is the friendliest to plants and the ecosystem [7,8,[11][12][13][14][15][16][17]. Irrigation is most effective in light and very light soils [8,[18][19][20][21][22][23][24][25]. Taking into account the high productivity of the potato, it is one of the most effective plant species in terms of using water for yield accumulation [26].…”

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. HargreavesDA 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.

“…Rolbiecki and Rolbiecki (2007) reported that irrigation significantly increased marketable yield of lettuce. Kirnak et al (2002) found that a 75% water deficit decreased lettuce yield by approximately 50% in greenhouse conditions.…”

Field experiments were conducted to characterize the effects of deficit irrigation on curly lettuce (Lactuca sativa var. Crispa cv. Bohemia) evapotranspiration, water use efficiency, marketable yield, yield components and mineral contents. The experiments were performed under semiarid climatic conditions in Erzurum province (east of Turkey) in the summer periods of 2005 and 2006. Irrigation water levels were selected to be 100% of usable soil water in full irrigation treatment (control) (T-100) and 80%, 60%, 40% and 20% of usable soil water in deficit irrigation treatments (T-80, T-60, T-40 and T-20, respectively). Average seasonal evapotranspiration was 232 mm in T-100 and 121 mm in T-20. Average marketable yield was 39.49 Mg ha -1 in T-100 and 14.57 Mg ha -1 in T-20. A linear relationship (y=0.23x-13.97; R 2 = 0.94) was found between seasonal evapotranspiration (x) and marketable plant yield (y). According to the regression equation, the yield response factor (k y ) was found to be 1.39, and the coefficient of determination 0.91. Average water use efficiency was 168.88 kg ha -1 mm -1 in T-100 and 117.39 kg ha -1 mm -1 in T-20. The lowest plant length, width, steam diameter, leaf number, macro and micro element content values were obtained for T-20 in both years.Additional key words: curly lettuce, deficit irrigation, evapotranspiration, macro and micro elements, yield components. ResumenComunicación corta. Efecto del riego deficitario en la lechuga rizada bajo condiciones de clima semiárido Se estudiaron los efectos del riego deficitario sobre la evapotranspiración, eficiencia del uso del agua, producción comercial y los contenidos minerales de la planta de lechuga rizada (Lactuca sativa var. Crispa cv. Bohemia). Los experimentos se realizaron bajo condiciones climáticas semiáridas en la provincia de Erzurum (este de Turquía), durante 2005 y 2006. Los niveles de agua aplicados fueron el 100% del agua útil del suelo en el tratamiento control (T-100), y el 80%, 60%, 40% y 20% de agua útil del suelo en los tratamientos de riego deficitario (T-80, T-60, T-40 y T-20, respectivamente). La evapotranspiración estacional media fue de 232 mm en el tratamiento T-100 y 121 mm en el tratamiento T-20. La producción comercial media fue de 39,49 Mg ha -1 en el tratamiento T-100 y 14,57 Mg ha -1 en el T-20. Se encontró una relación lineal (y = 0,23x-13,97; R 2 = 0,94) entre la evapotranspiración estacional (x) y la producción comercial de la planta (y). Según la ecuación de regresión, el factor de la respuesta de la producción (k y ) resultó ser 1,39 y el coeficiente de la determinación 0,91. La eficiencia media del uso del agua fue 168,88 kg ha -1 mm -1 en el tratamiento T-100 y 117,39 kg ha -1 mm -1 en el tratamiento T-20. Los valores más bajos de longitud, anchura, diámetro del tronco, número de hoja, macro y microelementos se obtuvieron en el tratamiento T-20 en ambos años.Palabras clave adicionales: componentes del rendimiento, evapotranspiración, lechuga rizada, macro y microelementos, riego deficitario.Abbreviat...
