Two field experiments were conducted at the Experimental Farm, Gemmeiza Agriculture Research station, Agricultural Research Center white maize (ARC), Egypt during two growing seasons (2014 and 2015), to study the response of two maize hybrids i.e., white maize single cross 128 and yellow maize single cross 176 to four nitrogen fertilizer levels i.e. 0, 45, 90 and 135 kg N/fad., and three phosphorus fertilizer levels i.e. 0, 15.5 and 31 kg P 2 O 5 /fad. Concerning the obtained results, SC 128 outyielded SC 176 in grain and biological yields (combined data) due to superiority in days to 50% tassiling and silking, leaf chlorophyll content, ear leaf area, leaf area index, relative photosynthetic potential for stover yield/plant, ear length and diameter, stem diameter, number of grains/row, hundred grain weight as well as grain and stover yields/plant, while SC. 176 gave the highest mean for each of plant height and relative photosynthetic potential for grain yield/plant. No significant differences among maize hybrid could be detected in relative photosynthetic potential for biological yield/plant, number of rows/ear, ear leaf efficiency and migration coefficient. Data of combined analysis revealed that addition of nitrogen (N) fertilizer and raising its rate up to 135 kg N/fad., was accompanied by asignificant increase in each of leaf chlorophyll content (mg m-2), plant height, leaf area index (LAI), ear length and diameter, stem diameter, number of rows/ear, number of grains/row, hundred grain weight, grain and stover yields/plant, ear leaf efficacy and migration coefficient, but relative photosynthetic potential for both stover and biological yields/plant were decreased. Increase of phosphorus (P) level up to 31 kg P 2 O 5 /fad., was followed by a significant increase in grain yield/fad., and almost all their attributes, but relative photosynthetic potential for both stover and biological yields/plant were decreased. Meantime, ear diameter responded to phosphorus addition up to 15.5 kg P 2 O 5 /fad., however, days to 50% tassling and silking were not significantly affected by varying phosphorus levels according to combined analysis. In almost cases, maize hybrid SC. 128 was more efficient and more responsive than SC. 176, where the former was is need to 135 kg N/fad., and 31 kg P 2 O 5 /fad., in order to maximize the grain yield to only 42.8 ardab/fad.

“…Maize is considered as one of the main cereal crops, ranks the third after wheat and rice. Increasing productivity of land area can be Radma and Dagsh, 2013;Modhej et al, 2014). In this respect, Sharifi et al (2009) showed that maize hybrids (SC 504, SC 404 and DC 370) significantly differed in plant height, stem diameter, number of kernels row -1 , cob length, number of kernels ear -1 and grain yield fad.…”

“…The results of some research work showed that the optimum N fertilizer level varied in amounts ranging between 90 and 100 Kg N/fad. (Hejazi and Soleymani, 2014;Khan et al, 2014;Modhej et al, 2014;Olusegun, 2015;Seadh et al, 2015). Moreover, other studies stressed the need of maize plants to N fertilizer levels up to 120 Kg N/fad., (El-Sobky, 2014;Sorkhi and Fateh, 2014;El-Kholy, 2015;Ikramullah et al, 2015).…”

Two field experiments were carried out in an administration field at Sheet Al Hawa Village, Kafr Sakr district, Sharkia Governorate, Egypt, during the two successive summer seasons of 2013 and 2014 to find out the effect of four N levels (30, 60, 90 and 120 kg N/fad.) as well as three phosphorus fertilization regimes (30 kg P 2 O 5 fad., phosphorien and 15 kg P 2 O 5 /fad., with phosphorien) on yield potentiality of three yellow maize hybrids (SC 168, SC167 and TWC 352). The results could be summered as follows: In case of douple eared plants: Results revealed that the three maize hybrids gave significant differences in the majority of the studied characters of maize crop, since the SC 167 hybrid was superior in most yield attributes as it recorded high value in each of ear length, number of grains/row and hundred grain weight, followed by SC 168 and TWC 352 in descending order. Results of the combined analysis revealed that each N increment from 30 to 60 and 90 and then to 120 kg N/fad., significantly increased ear length, but this response was up to 90 kg N/fad., in each of number of grains/row and number of rows/ear, whereas hundred grain weight responded up to 30 kg N/fad., Addition of 15 kg P 2 O 5 /fad., with phosphorien gave high value in each of ear length, number of grains/row, number of rows/ear and hundred grain weight. In case of mono eared plans: The findings revealed that the three maize hybrids gave significant differences in the majority of the studied characters of maize crop, since the SC 167 hybrid was superior in most yield attributes and grain yield/ fad., followed by SC 168 as well as TWC 352. This superiority was expressed in ear length, number of grains/row, hundred grain weight, ear grain weight, while TWC 352 was superior in number of rows/ ear. Results of the combined analysis revealed that each nitrogen increment up to 90 kg N/fad., was accompanied by a significant increase in ear length, number of grains/row, whereas each of number of rows/ear and ear grain weight as well as grain yield/fad., responded up to 120 kg N/fad. In addition, the studied treatments showed that the application of 15 kg P 2 O 5 /fad., along with bio-fertilizer phosphorien gave the highest mean records in each of ear length, number of rows/row, hundred grain weight, ear grain weight whereas when maize plants were fertilized by 30 kg P 2 O 5 /fad., or phosphorien only gave higher grain yield/fad. The most interaction effect was observed between maize hybrids on one hand and each of N level and phosphorus treatments on the other hand. SC 167 had the highest grain yield averages under both 120 kg N/fad., and addition of phosphorien, whereas TWC 352 recorded the lowest grain yield under 30 kg N and phosphrien only.
