“…The superior performance of compost treated may be due to rapid decomposition of organic matter in the compost as compared to that in rice straw or sawdust. This influences soil physical and chemical properties such as soil organic matter, bulk density, microbial biomass, aggregate stability and soil structure, infiltration water holding capacity and cation exchange capacity (Abdou, 2004;Eshraga, 2011;Khatab et al, 2015).…”

“…Soil organic carbon and nitrogen are important determinants of soil quality because they positively affect water retention, soil aeration, nutrient status and retention, and plant root growth (Mahdi et al, 2005). Application of soil conditioners resulted in improved soil organic matter, bulk density, microbial biomass, aggregate stability, infiltration water holding capacity and cation exchange capacity (Aziz-Nagat, 2002;Ashry, 2003;Abdou, 2004;Eshraga, 2011;Khatab et al, 2015).…”

Maize is the third important cereal crop in Egypt after wheat and rice. Injection of ammonia gas as a nitrogen fertilizer is used widely comparable with other nitrogen fertilizer forms due to the high nitrogen content (82 %) as well as its cheapest price. Two field trials were carried out at Tameia Agricultural Research Station, Fayoum Governorate, Egypt during 2014 and 2015 summer seasons to study the effect of nitrogen fertilization forms (ammonia gas 82 N% and ammonium nitrate 33.5N%), irrigation intervals and soil conditioners on yield, yield components and water use efficiency (WUE) water use efficiency of maize. Results showed that a combination of ammonia gas, irrigation at 10 days interval and application of compost caused the lowest averages of dry soil bulk density and hydraulic conductivity, whereas, this interaction also recorded the highest value of grain yield in both seasons, as well as, higher values of concentration and uptake of N, P and K in grain. On the other hand, the treatment of ammonia gas, irrigation at 15 days and application of compost remarkably had the higher water use efficiency (WUE) than the irrigation at 10 days with the application of compost. Although, the yield production reduced by 5 to 6 % , it saves irrigation water 400m 3 ha -1 water. Hence, the treatment of irrigation at 15 days and application of compost is recommended for adoption in wider areas in Egypt to save irrigation water.

“…Such attempts could be achieved either by increasing its cultivated area or by the productivity of unit area using high yielding hybrids as well as improving the culture practices. It is well known that maize crop had high irrigation requirements as well as it is sensitive crop to water stress during some growth stages (Ahmadi et al, 2010;Kotb & Mansour, 2012;Mubeen et al, 2013;Khatab et al, 2015). Therefore, the optimal water management strategies become an important factor for raising maize production due to limitations in the irrigation water supply in Egypt.…”

Increasing irrigation intervals from 12 up to 17 and 22 days significantly decreased number and area of leaves and leaves, stem and total dry weight/plant, total chlorophyll, relative water content (RWC), plant height, length and diameter of ear, number and weight of grains/ear, 100 grain weight as well as grain, stover and biological yields/fed, protein and oil % and yields/ fed, but significantly increased proline content in leaves in both seasons. 2-S.C 168 G surpassed the other genotypes in area and dry weight of leaves/plant, grain yield/fed, crop and harvest indices as well as protein yield/fed. T.W.C 368 G was superior in stem and total dry weight/plant, plant height, ear diameter, no.of grains/ear,100-grain weight as well as stover and biological yields/fed. However, S.C 168 G and T.W.C 368 G recorded the best values of RWC, no.of ears/plant, grain weight/ear, protein% and oil yield/fed as compared with the other genotypes. The highest significant values of proline content and no.of leaves/ plant were obtained by T.W.C 352 G and T.W.C 360 G, respectively in both seasons. 3-Maize genotypes S.C 168 as well as T.W.C 360 and T.W.C 352 under I 2 and T.W.C 368 under either I 2 or I 3 had the lowest values of relative yield reduction and drought suS.Ceptibility index (< 1), indicating that those genotypes are relatively drought tolerant genotypes compared to other tested genotypes in our experiment condition.

Field experiments were carried out at the Tameia Agricultural Research Station, Fayoum Governorate, Egypt, during the 2013/14 and 2014/15 seasons in order to study the impact of nitrogen fertilization forms, irrigation intervals and some soil conditioners on the yield, yield components and crop water relations of wheat (Giza 168). Two nitrogen forms with three irrigation intervals, i.e. I 1 : irrigation at 14 days, I 2 : 21 days and I 3 : 28 days with soil conditioners at the rate of 11.9 t ha -1 , i.e. C 1 control (without any addition), C 2 : compost, C 3 : rice straw and C 4 : sawdust with three replications in a split-split plot design. Results indicate that the highest wheat grain yields in both years were detected from a combination of applying liquid ammonia gas, irrigation at 14-day intervals and addition of compost. This treatment also gave higher values for yield components, uptake of nitrogen, phosphorus and potassium and their concentration in the grain. Further, it resulted in highest values for the consumptive use of water as well as water productivity. Thus, a combination of applying liquid ammonia gas, irrigation at 14-day intervals and addition of compost can be adopted in wider areas in Egypt for enhanced wheat grain yield.
