“…Total annual area cultivated with maize varieties was estimated 1.5-2.0 million feddans. Total national production of maize is about 5.43 million tons, while the demand is for at least 7 million tons (El-Atawy and Eid, 2010). This reflects the size of the problem and efforts that needed to increase maize production.…”

Two field trials were carried out at the Experimental Farm, Sakha Agricultural Research Station, Kafr El-Sheikh Governorate during the two successive summer growing seasons of 2012 and 2013. The research aimed to study the effect of irrigation at different soil moisture depletion (I1: at 45%, I2: at 60% and I3: at 75% depletion of available soil moisture, respectively), nitrogen rates (N1: 60, N2: 90 and N3: 120 kg N fed -1 ) and doses number of nitrogen application (D1: one dose, D2: two equal doses and D3: three equal doses) on maize yield and its components, nitrogen uptake by plants, N-use efficiency and some water relations. The experimental design was split split plot with three replicates, the main plots were for irrigation treatments, where the sub plots were for N-rates and the sub-sub plots were for doses number of N application. The main results can be summarized as follows:  Irrigation at 75 % depletion of available soil moisture (I3) decreased seasonal water applied, water consumptive use and water stored in the effective root zone by 18.08, 16.78, and 17.02%, respectively compared with irrigation at 45% depletion. Also, the highest means of water productivity (WP) and productivity of irrigation water (PIW) were 1.95 and 1.24 kg/m 3 , respectively with irrigation at 60 % depletion (I2).  Irrigation at 60% depletion (I2) recorded the highest mean of water application efficiency (89.60%), whereas the irrigation orders was I2> I3>I1.  Irrigation at 45% depletion (I1) recorded the highest mean for grain yield (3.363 ton fed -1 ), stalks yield (9.313 ton fed -1 ), weight of 100 grains (43.899g) and ear weight (316.119g).  Application of N-rate N3 recorded the highest means of grain yield (3.507 ton fed -1 ), straw yield (9.56 ton fed -1 ), weight of 100 grains (43.176g) and ear weight (310.948g), respectively.  Application of N-rate at three doses (D3), recorded the highest means of grain yield (3.585 ton fed -1 ), straw yield (9.216 ton fed -1 ), weight of 100 grains (43.466g) and ear weight (315.202g).  Irrigation at 45% depletion (I1) recorded the highest mean of N-uptake for grains and stalks.  Application of nitrogen rates increased N-uptake for maize grains and stalks up to N3.  Increased the doses number of N application increased N-uptake for maize grains and stalks up to D3 (three equal doses). The values of NUE increased by 15.65% with splitting N-rate into three doses compared with application at one dose, but decreased with increasing application N-rate and irrigation at 75 % depletion.  Most of interactions among irrigation, nitrogen rates and doses number of N application showed significant effect on grain yield and its components and N-uptake in both maize grains and stalks, and positive effect on N-use efficiency Aiad, M.

Two field experiments were implemented at El-Gemmieza Agric., Res. Station, Agric., Res., Center in El Gharbiah Governorate, Egypt through (2017/2018) seasons to investigate the impact of rice straw and compost application on soil physicochemical properties, water use efficiency and production of both wheat and maize yields. The design of experiment was complete randomized blocks design with three replicates, the experiment comprises the following treatments: T 1 : (control), T 2 : 2.50 t ha -1 (RS), T 3 : 5.00 t ha -1 (RS), T 4 : 5.00 t ha -1 (C), T 5 : 2.50 t ha -1 (RS) + 5.00 t ha -1 (C) and T 6 : 5.00 t ha -1 (RS) + 5.00 t ha -1 (C). Results showed that the applied of all organic treatments improved organic carbon, total N, C/N ratio and pH in soil when in all sample that was taken monthly at (30, 60, 90, 120, 150, 180,210, 240, 270, 300, 330 and 360 days from incubation rice straw and compost as compared to control treatment. Results show that applied T 6 gave the best values of total porosity and hydraulic conductivity but the bulk density decreased than other treatments. The same trend was noticed concerning application T 6 treatment which improved crops and water use efficiency of both wheat and maize as well as increased content (%) and uptake (Kg ha -1 ) of nitrogen, Phosphors, and potassium of grains and straw of both wheat -maize crops as compared to other treatments. It seems that the characteristics parameters of soil and plants has followed the sequence T 6 > T 5 > T 4 > T 3 > T 2 > T 1 .

“…This reflects the size of the problem and efforts that needed to increase maize production. This can be achieved by breeding high yielding varieties and by the application of improved agro-techniques (El-Atawy et al, 2010). The actual water use by crop varies greatly due to the variation of seasons and locations, depending on the evaporative conditions of the atmosphere and the crop characteristics (Nabila et al, 2014).…”

Field experiments were carried out at the experimental farm of Water Studies and Research Complex (WSRC) Station, National Water Research Center, Toshka-Abu Simbel city, Egypt during the two summer seasons of 2015 and 2016 to study the effect of three irrigation methods including new types of micro irrigation, pulse irrigation technique and silicon application on water relations of maize (Giza-358, variety) as well as yield and yield components. The experiments were laid out in split plots design with three replicates and consisted of three treatments. The results indicated that the effect of pulse irrigation technique on water use efficiency were larger than the effect of irrigation system and silicon application, the mean values of water use efficiency were (0.56, 0.52 and 0.52 kg/m 3) for pulse irrigation technique, irrigation system and silicon application, respectively. Also the results showed that grains yield (ton/fed) was increased for combined irrigation system and pulse irrigation technique which had been recorded (1.4 ton/fed) while the mean values of silicon application were (1.3 ton/fed). Finally, under the current experimental conditions, it could be concluded that pulse technique and silicon application under combination irrigation system is suitable under Toshka climatic conditions and caused significant increases in WUE and grain yield.
