“…The relative increasing of water utilization efficiency due to 286 kg N ha -1 reached to 16.0 and 16.5% over 214 kg N ha -1 in both seasons, respectively. These results agree with those obtained by Eid et al (2010) and Ewis et al (2016).…”

“…Regarding nitrogen level, the data revealed that increasing nitrogen level from 214 to 286 kg ha -1 positively decreased water use efficiency. These results are mainly explained by the effect of nitrogen on improving the growth of roots and shoots of maize, consequently improved water absorption (Ewis et al, 2016). These results coincided with those obtained by Yang et al (2005), El-Atawy (2007) and Eid et al (2010).…”

“…The reduction in maize yields resulted in decreasing the availability of soil moisture content (I 3 treatment) and could be attributed to water shortage (Eid et al, 2010). These results are similar to those obtained by Shinde et al (2014) and Ewis et al (2016). As for nitrogen sources, the data show that both grain and stover yields were significantly affected by nitrogen sources.…”

“…The effect of nitrogen sources on water use efficiency could be arranged in the descending order as follow: urea> ammonium nitrate > ammonia gas. These results may be due to the effect of different nitrogen fertilizers on seasonal consumptive use (Ewis et al, 2016). Regarding nitrogen level, the data revealed that increasing nitrogen level from 214 to 286 kg ha -1 positively decreased water use efficiency.…”

T WO FIELD experiments were conducted in two successive summer seasons during 2016 and 2017 at Sids Agricultural Research Station, Beni-Suef Governorate, Egypt. This research was carried out to study irrigation schedule impact using pan evaporation method (Class A pan and irrigation at 0.7, 1.0 and 1.3 pan evaporation coefficient, APE) with different nitrogen sources (ammonia gas, ammonium nitrate and urea) and levels (214 and 286 kg N ha -1 ) on maize yield attributes as well as some water relations, namely, seasonal applied water (AP), seasonal consumptive use (CU), water utilization efficiency (WUtE) and water use efficiency (WUE). Results showed that increasing pan evaporation coefficient from 0.7 up to 1.3 increased maize yield and improved its attributes, N, P and K uptake by grains and/or stover, seasonal applied water and seasonal consumptive use. The differences between the effect of 1.0 and 1.3 of APE on maize grain and stover yields were not significant. Irrigation at 1.0 APE gave the highest WUtE and WUE followed by irrigation at 1.3 APE. Whereas the lowest one produced under 0.7 of APE Added nitrogen as anhydrous ammonia increased all studied yield and its attributes, N, P and K uptake, seasonal consumptive use, water utilization efficiency and water use efficiency followed by ammonium nitrate, while urea fertilizer exhibited the lowest ones. Increasing nitrogen levels from 214 to 286 Kg ha -1 improved maize yield and its attributes, N, P and K uptake as well as the studied water relations. The best treatment for maize productivity and water relation is to irrigate at 1.0 of APE with nitrogen addition as ammonia gas at the rate of 286 Kg ha -1 , while saving about 960 m 3 per hectare with no significant decrease in yield. This study confirms that maize irrigation at different pan evaporation coefficient (0.7, 1.0 and 1.3) with different nitrogen fertilization sources and levels affect maize productivity traits and some water relations.

“…Also, the results show that the average water utilization e ciency (WUtE) as affected by irrigation treatments and N-fertilizer rates in the rst and second seasons was 6.68, 7.21&7.88 and 6.54, 7.15&7.66 kg m-3, respectively. These results collaborate with et al whose, reported that WUtE was positively responded to increasing nitrogen level up to 150 kg N fed −1 which mainly due to the effect of nitrogen on improving the growth of roots and shoots of maize in turn improved water absorption from soil 40 .…”

The teosinte plant is one of the most important fodder crops that is affected by drought and nitrogen supply, and therefore the optimal supply of N- fertilization may be affected by the amount of irrigation water added to teosinte plants to obtain an economic crop. Two field experiments were done to study the effect of irrigation amount at three levels (100%, 80% and 120%) and nitrogen fertilizer levels (60, 90 and 120 kg N fed-1) (Feddan = 4200 m2) on the yield productivity of teosinte and determined the optimal and economic optimal N rate as affected by irrigation amount levels, and water relations. The results showed that the highest values of the fresh and dry weight of cuts, as well as plant height and stem diameter, were obtained when applying the full irrigation rate with full irrigation and 120 kg N fed-1. The results also showed that a 20% decrease in the irrigation rate led to a deterioration in the values of those parameters. Although the results showed that the full irrigation amount more saved water at two seasons under various levels of nitrogen. Moreover, all water relationships gave the best mean values for actual evapotranspiration, water utilization and use efficiencies also, higher application efficiency values at full irrigation and 120 kg N-levels than the other treatments. Also, the results showed that the economical yield of teosinte fresh cuts when using 211.01 kg N fed-1 with 120% of the recommended irrigation rate was higher when using 148.22 kg N fed-1 with the recommended irrigation rate. Therefore, we recommend using 211.01 kg N fed-1 to get an optimum economic yield of teosinte fresh cuts, especially in saline soil, with 120% of the recommended irrigation rate.

and 71m altitude ASL) to evaluate the effect of different irrigation regimes (80, 100 and 120% of reference evapotranspiration (ETo) and various intercropping patterns (wheat and faba bean intercropped with sugar beet) under drip irrigation system on sugar beet yield and its traits, crop water productivity and land equivalent ratio. The obtained results showed that sugar beet yield and its traits were decreased as the irrigation regime increased and with intercropping system with wheat or faba been. On the average bases of both seasons, sugar beet yielded 20.29, 18.17 and 16.64 ton/ feddan (feddan = 4200 m² = 0.420 hectares = 1.037 acres) at 120, 100 and 80% ETo, respectively. The relative reductions were 21.94 and 9.19% at 120, and 100% ETo compared to 80% ETo. Also, sugar beet yielded 19.48, 17.64 and 17.99 ton/feddan at sole sugar beet, intercropped sugar beet with wheat and intercropped sugar beet with faba bean, respectively. The reduction in sugar beet yield was 9.45 and 7.65% when intercropped with wheat and faba bean, respectively compared to that yielded for sole sugar beet. On the average basis of both seasons, the crop water productivity (CWP) values were 5.21, 5.60 and 6.35 kg/m 3 at 120, 100 and 80% irrigation regime, respectively regardless the intercropping system. At 120% ETo, the CWP values were 4.82, 5.08 and 5.73 kg/m 3 for sole sugar beet, sugar beet + wheat and sugar beet + faba bean, respectively. At 100% ETo, the CWP values were 5.24, 5.43 and 6.14 kg/m 3 for the corresponding sole and intercropping system. The CWP values were 6.23, 5.99 and 6.83 kg/m 3 for the corresponding sole and intercropping system at 80% ETo. The highest land equivalent ratio (LER) value (1.70) was recorded when sugar beet intercropped with faba bean and irrigated at 80% ETo while the lowest one (1.25) was attained when sugar beet intercropped with wheat and irrigated at 80% ETo. On the average basis of both seasons, the saved lands were 36.92, 35.51 and 29.71% at 120, 100 and 80% ETo, respectively regardless the intercropping system.
