“…For example,Topak et al (2011) applied irrigation water of 244.2 mm (water use 374.5 mm) and obtained root yield of 28.1 t h a 1 and WSY of 5.25 t ha'1 for the drip-irrigated sugar beet in semi-arid Konya, Turkey region.Ugan and Genqoglan (2004) got the root yield of 10.4 t ha'1 and sugar yield of 1.94 t ha'1 in sugar beet irrigated by using a line-source sprinkler system obtained for the irrigation water of 363.5 mm (water use 541 mm) in semiarid Kahramanmarag, Turkey region. Similar results were published bySahin et al (2007) for surface irrigated sugar beet in Erzurum conditions with semiarid climate.…”

Effective water use should be investigated in terms of sustainable production strategy in arid and semi-arid regions. A 2 yr field study was conducted in order to investigate the effects of full root-zone wetting (FI) and partial root-zone drying (PRD) irrigation techniques with 4 (II) and 8-d (12) irrigation intervals and three different irrigation levels (W I, W2, W3) adjusted according to Class A pan evaporation on root, leaf, and sugar yields and irrigation water use efficiency (IWUE) of sugar beet (Beta vulgaris L.) Three different plant-pan coefficients (0.70, 0.60. and 0.50) were used for adjusting the three different irrigation levels. The irrigation techniques and levels affected yields significantly. Seasonal meanly irrigation quantities were 280.4 mm in FI treatments and 162.4 mm in PRD treatments. While mean root yield of 33.80 t ha'1 is obtained in FI treatments, it was 26.43 t ha'1 in PRD treatments. Similarly, mean white sugar yield (WSY) for FI treatments (5 t h a 1) was higher than PRD treatments (3.81 t ha"1)-There were significant polynomial relationships between irrigation quantities and root yield or WSY in both FI and PRD treatment. PRD technique increased by 34.9% IWUE compared to FI. Although the highest root yield was determined in FI-11W1 sub treatment as 37.571 ha"', the highest IWUE was determined in PRD-I1W3 sub treatment as 173.9 kg ha 1 mm"1 since it has the lowest irrigation water amount as 140.6 mm. However, among PRD treatments for more root yield and for more white sugar yield, I1W1 and I1W2 sub treatments were the best.

“…Plant-pan coefficients of 0.70, 0.60, and 0.50 were selected considering the value of 0.50 suggested for sugar beet irrigated with surface method in this region by Sahin et al (2007). The wetting factor during growing period was determined by dividing the plant row interval by the plant cover width (Ertek and Kanber, 2003).…”

“…Crop coefficients (Kc) for potato have been documented significantly by previous studies to irrigate crops. [28][29][30] Carvalho et al, 12 calculated K c values of 0.35, 0.45, 1.29, and 0.63 for potato (Solanum tuberosum L.) at different stages of crop development. Fan et al, 31 calculated the water-use efficiency (WUE), ET, and yield (Y) for crops through statistical analyses of the data, whereas Salvador et al, 32 applied WUE and water productivity indicators to evaluate irrigation performance, as well as the variance among irrigation methods and yields in the Ebro basin of Spain.…”

Here, we address the issue of water management for potato (Solanum tuberosum L.) crops under arid conditions in Saudi Arabia over a 5-year period (2011-2016). Daily evapotranspiration for irrigated potato crops (ETc) was determined over a period of three successive seasons. Non-weighing (drainage) lysimeters were used in four regions: Riyadh, Qassiem, Eastern Province, and Al-Jouf. Crop coefficients (Kc) were determined using lysimetric data and an alfalfa-based reference crop evapotranspiration (ETr) during each growing season. Measured (M-ETr) and predicted, (P-ETr) for different regions were compared. Comparisons between M-ETr and P-ETr show higher trends for the measured values in all regions, with averages of 5.72 mm/d, 4.42 mm/d, 5.06 mm/d, and 7.94 mm/d for the Riyadh, Qassiem, Eastern Province, and Al-Jouf regions, respectively. Differences in the ETr and ETc were also observed among the regions due to geographic and climatic variations. In addition, the water-use efficiency of potato crops was generally highest (5.45 kg m-3) in Riyadh and lowest (1.54 kg m-3) in Qassiem. Analysis of projected net returns for irrigated potato production revealed that greater economic potential exists.

“…They found also that the values of Penman -Montieth method and the modified Penman, introduced a new method which gives estimates of ET o near to those of the best method of Doorenbos-Pruitt. Sahin et al (2007) determined crop coefficients for sugarbeet and potato under cool season semiarid climate in Turkey. From May to October in 2003 and 2004, ET c was measured by the water balance approach, and the ET r by FAO Penman-Monteith.…”

Two field experiments were carried out at Mallawi requirements research station El-Minia Governorate, Egypt; Water Management Research Institute -National Water Research Center during 2012 and 2013 seasons.The aim of this investigation is to evaluate the effect of the different irrigation regimes and potassium fertilization rates on crop coefficient of potato. Also it evaluate and compare the potential evapotranspiration (ET p ) with actual water requirement under El-Minia Governorate conditions. The experiment included five treatments of irrigation regimes (A) and four treatments of potassium fertilization (B) with three replicates so that the experiment was arranged in a split plot design. The irrigation regime treatments were treationial irrigation (the farmers practes, 100%, 90%, 80% and 70% of field capcity). Potassium rates was applied in a form of potassium sulphate (48%K 2 O) at rate 200 kg/fed. (b 1 ), 100 kg K 2 O/fed. + potasine (Biofertilizer) at rate 6 liters/fed (b 2 ), 100 kg/fed. + potasine (Biofertilizer) at rat 6 liters/fed. + potassium foliar (36% K 2 O) at rate 2 liters/fed. (b 3 ) and Potassium (biofertilizer) at rate 6 liters/fed (b 4 ).These results indicated that the first irrigation treatment where plants irrigated with conventinal irrigation had the highest value of actual consumptive use (daily and seasonal). This was due to the decrease in the value of tension moisture of the first treatment which led to increasing the water actual consumptive use. While, the fifth irrigation treatment for plants irrigated until 70% of field capacity had the lowest value of actual consumptive use (daily and seasonal). The application of Potassium fertilization caused a slight decrease in daily, monthly and seasonal actual evapotranspiration(ET a ), in both seasons. Modified Penman and modified Blaney & Criddle gave high average values for potential evapotranspiration (ET p ) (63.24 and 56.50 cm/season) while radation method and pan method gave less average values (53.99 and 49.11 cm/season) for the two studied seasons respectively. The actual values of evapotranspiration were less than those computed by climatological equations. This is due to the estimated factors in these equations.The average values of potential evapotranspiration (ET p ) for the two studied seasons, by modified Blaney & Criddle and radation method were the nearest values to general average (+1.41 and -3.09% respectively). While, the farthest values to general average were obtained by modified Penman and Pan method (+13.52 and -11.85% respectively). Kc average were 0.76, 0.72, 0.71, 0.70 and 0.68 for A 1 , A 2 , A 3 , A 4 and A 5 under all subtreatments respectively. Modified Blaney & Criddle was the nearest to the actual consumptive use.Therefore, recommended for calculating the potential evapotranspiration using modified Blaney & Criddle or radiation method for potato plants which grow under El-Minia conditions and other corresponding conditions.
