“…(25.99 cm) and 918.72 m 3 fed -1 (21.87cm) for the irrigation level of I 1, I 2 and I 3 , respectively, in the 1 st season. The corresponding average values for the 2 nd season were1263.36 m 3 fed -1 (30.08 cm), 1089.73m 3 fed -1 (25.95cm) and 916.13 m 3 fed -1 (21.81cm).These results were in agreement with those obtained by (Bastos et al, 2012 andOzmen et al, 2015) they stated that, in watermelon, deficit irrigation at 75% ETC saved 25% of irrigation water applied. In addition, data indicate that water saving percent over I 1 -treatment were (13.71 and 13.74%) and (27.37 and 27.48%) for I 2 and I 3 -treatments, respectively in both seasons.…”

“…According to the literature, watermelon has high water requirement for high yields, the seasonal water requirement of watermelon vary from 240 to 660mm, depending on the climate and the total length of the growing period (Kirnak and Dogan, 2009;Camoglu et al, 2010;Bastos et al, 2012;Ozmen et al, 2015 andKuscu et al ., 2015). Therefore, irrigation is necessary for optimal vegetative and reproductive development in the periods of insufficient precipitation during the plant production seasons (Sahin et al, 2015).…”

A FIELD experiment was conducted in farmer's field located at Gammsa district, Dakahlya Governorate, Egypt, during two successive winter seasons 2017 and 2018 to determine and evaluate the response of watermelon grown on sandy soil to three irrigation regimes; 100%(I 1), 85%(I 2) and 70%(I 3) of soil field capacity and four applications of bio-mineral fertilizers; F 1 Applying the recommended dose of NPK (100%RNPK), F 2 (85%RNPK + biofertale), F 3 (70%RNPK + rhizobacterien) and F 4 (55% RNPK+ mixture of biofertale + rhizobacterien). Results showed that both of irrigation and fertilization treatments had highly significant effect on yield and its components of watermelon plants in both seasons. Maximum fruit yield and its components were achieved with I 2 and F 3 treatments in both seasons. Irrigation with (I 2), led to increase fruit yield by (14.26 and 14.30%) compared with I 1 and the corresponding values (11.72 and 12.97%) with (F 3) compared with F 1 in 1 st and 2 nd seasons, respectively. I 3 achieved higher values of TSS, vitamin C, soluble sugar, PIW and water saving. Moreover, F 3 followed by F 4 produced the highest value of PIW in both seasons compared with F 1. The combination of I 2 F 3 has superiority in increasing fruit yield and its quality, net return and economic efficiency. Net return from water unit was resulted from the combination of (I 3 F 4) and (I 3 F 3) as compared with (I 1 F 1) in both seasons, respectively.Generally, it could be concluded that I 2 F 3 or I 2 F 4 is the most efficient treatment for achieving economical watermelon fruit yield, economic return and saving water and mineral fertilizers.

“…According to (Amaral et al, 2016) the productivity and final quality of the watermelon crop were related to several factors, which acted during all phases of its growth and development. In this study similar acts of growth and development determinant factors related to irrigation, the amount was observed during the period of the experiment at both locations.…”

Determining the optimum crop water requirements is considered one of the most important factors affecting plant productions. Excessive application of water can damage watermelon and face fruit quality with problems, leading to a reduction of the melon fruit yield, lower fruit quality characteristics, and plant disease. Therefore, the main objective of this study was to determine the crop water requirement of watermelon in a field experiment using the CROPWAT model at Koga and Rib irrigation schemes. The experiment was conducted from 2016 to 2018 irrigation seasons for two years in the Amhara region, Ethiopia. The experiment was arranged in a randomized complete block design having 12 treatments; three irrigation intervals (14, 21, and 28 days) and the model generated depth of 50 %, 75 %, 100 %, and 125 %. The results indicated that 75 % depth of water applied within 14 days interval at Koga irrigation scheme gave a total of 40.2 t ha −1 yield with water productivity of 0.29 kg m −3. In the case of Rib, 75 % of irrigation depth showed that better yield production within 21 days irrigation interval and produced 67.9 t ha −1 fruit yield with water productivity 0.94 kg m −3. In both locations, the fruit diameter and fruit length were not statistically significant among treatments. Generally, this research showed that an appropriate regime of irrigation had significantly increased crop water use and yield production.

“…These include plant, soil, cultural practices, environmental factors (Jones et al, 1984;Allen et al, 1998), applied irrigation system (Al-Jamal et al, 2001). Under no limiting irrigated conditions, daily ET rates for individual vegetable crops are directly related to the meteorological processes affecting evaporative demand and to the existing stage of growth development or percent crop coverage (Blaney and Criddle, 1962). According to the literature, watermelon has high water requirement.…”

Summary The objective of the study, conducted in Vojvodina a northern part of the Serbia Republic, was to analyse the effect of drip irrigation on yield, evapotranspiration and water productivity of watermelon (Cirullus lanatus Thunb.) grown with plasticulture. Irrigation was scheduled on the basis of water balance method. Daily evapotranspiration was computed using the reference evapotranspiration and crop coefficient. The yield of watermelon in irrigation conditions (37,28 t/ha) was significantly higher compared to non irrigated (9,98 t/ha). Water used on evapotranspiration in irrigation conditions was 398 mm and 117 mm on non irrigated variant. The crop yield response factor of 1,04 for the whole growing season reveals that relative yield decrease was nearly equal to the rate of evapotranspiration deficit. The values of irrigation water use efficiency and evapotranspiration water use efficiency were 9,93 kg/m3 and 10,29 kg/m3 respectively. The determined results could be used as a good platform for watermelon growers in the region, in terms of improvement of the optimum utilization of irrigation water.
