“…This is attributed to two reasons: (1) the climate exhibited high air temperatures, thereby making the potatoes sensitive to drought; and (2) the soil water content within the root zone of the potatoes was different due to the application of different irrigation treatments [28,53]. Hence, the WP values of the water-saving treatments were lower than the value of FI in 2014, which agrees with the results of Ahmadi et al [54] who discovered that the WP values of the PRD treatments significantly decreased by 31% to 41% in comparison with FI treatment. Moreover, DI treatments had higher WP values than PRD treatments, which is consistent with the results of Liu et al [16] and Ahmadi et al [54].…”

In this study, field experiments were conducted to investigate the effects of two water-saving practices-partial root-zone drying (PRD) and deficit irrigation (DI)-on potato growth and yield in comparison with full irrigation (FI). The required FI amount was applied to the potato plants to enable 100% crop evapotranspiration, and the plants received 70% and 50% of the irrigation amount of FI for DI (DI70 and DI50) and PRD (PRD70 and PRD50), respectively. The physiological characteristics of the potatoes during the 2014-2015 seasons indicated that the relative chlorophyll contents were not significantly higher for the DI and PRD treatments than for the FI treatment. The DI50 had the lowest net photosynthesis rate (p < 0.05) while DI50 and PRD50 had significantly lower stomatal conductance (g s ) values in both years. Meanwhile, the values of the PRD treatments were lower than those of DI treatments based on the transpiration rates. The xylem (abscisic acid) based on PRD50 had an average increase of 0.38 mol/m 2 s due to decreasing g s values compared with other water-saving irrigation treatments. However, the FI and DI treatments had increased fresh tuber yields compared with the yields of PRD treatments. Furthermore, the PRD70 and PRD50 treatments significantly reduced the water productivity (WP) values by 30.16% and 41.32%, respectively, relative to that of FI.

“…Except for HI by S * U interaction, no significant differences occurred between variables in Table 4. Results are in agreement with those obtained by [33], working on potato, found that tuber yield and plant dry matter were significantly affected by irrigation regimes. [8] [17] [34] [35], working on potato, found that potato yield and yield components were significantly changed by growing season, irrigation method and regimes.…”

Potato growth, yield, and quality under improved irrigation methods and non-uniformity of their irrigation applications are important to enhance water management in arid regions. A field experiment was conducted in 2014 spring and fall growing seasons using potato (Solanum tuberosum) grown in northern Egypt at Shibin El Kom, Menofia, Egypt to evaluate potato response to furrow or trickle irrigation. A Randomized Split-Plot Design with irrigation method randomly distributed and non-uniformity of irrigation applications evaluated along either irrigation furrow or trickle lateral as dependent variables measured at the 3 rd , 13 th , 23 rd , 33 rd , 43 rd and 53 rd m along the 55 m irrigation line. Traditional (TF) and partial (PF) furrows as well as trickle point (TP) and line (TL) sources were used as irrigation methods. Each treatment was repeated three times. For a 33 rd m treatment, seasonal optimum water use by potato was 328, 234, 269 and 292 mm over 118 days in spring and 200, 164, 178 and 186 mm over 122 days in fall under TF, PF, TP and TL irrigation methods, respectively. Potato tuber yield and quality were significantly affected by growing season (S), irrigation method (I) and non-uniformity of irrigation application (U). Tuber yield, total soluble solid (TSS) and leaf area index (LAI) were significantly affected by I and U, and their interaction I * U; harvest index (HI) was not affected by I but U. Except for TSS by S * I and HI by U * I and S * I, results showed no significant differences. Moreover, tuber weight, number and marketable yield were significantly affected by S, I, U and I * U interaction, except medium tuber size and culls by S. A given 33 rd treatment under partial furrow and trickle irrigation, relative to that of traditional furrow, enhanced tuber yield and improved quality in both growing seasons. In non-uniform irrigation application over two growing seasons, potato crop response was developed under varied irrigation methods. Tuber yields were significantly affected in a linear relationship (r 2 ≥ 0.75) by either water deficit or excessive water under irrigation methods.

“…However, another study by Liu et al (2006b) showed that exposure of potato to the PRD treatment during the tuber initiation phase did not have similar advantage compared to the FI or CDI treatment. Ahmadi et al (2014) reported that compared to FI, the static CDI and dynamic CDI strategies in field-grown potato increased water productivity (WP) by 28% and 34%, respectively, with a slight fresh tuber yield reduction, but static PRD and dynamic PRD decreased WP by 40% and 31%, respectively. Jovanovic et al (2010) studied the effect of PRD drip irrigation on irrigation WEU and yield of field-grown potato and reported that IWUE was significantly higher in PRD irrigation compared to FI irrigation.…”
