“…Similar results were observed regarding chlorophyll content (Table 1), LAI and relative photosynthetic potential for grain yield/plant (Table 3), Plant height and ear leaf area (Table 2), ear length and stem diameter (Table 4), row number/ear and grain number/row as well as hundred grain weight (Table 5) and grain yield/ plant and biological yield/ plant. These results are in agreement with those reported by Khan et al (2005), Ahmad et al (2007), Hussein (2009) and Khan et al (2014) as they reported significant increase in grain and biological yields/ fad., due to addition of P up to level of (60, 90 , 120 kg P 2 O 5 ha -1 ), respectively.…”

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.

This review outlines nitrogen (N) responses in crop production and potential management decisions to ameliorate abiotic stresses for better crop production. N is a primary constituent of the nucleotides and proteins that are essential for life. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment. Therefore, increasing plant N use efficiency (NUE) is important for the development of sustainable agriculture. NUE has a key role in crop yield and can be enhanced by controlling loss of fertilizers by application of humic acid and natural polymers (hydrogels), having high water-holding capacity which can improve plant performance under field conditions. Abiotic stresses such as waterlogging, drought, heat, and salinity are the major limitations for successful crop production. Therefore, integrated management approaches such as addition of aminoethoxyvinylglycine (AVG), the film antitranspirant (di-1-p-menthene and pinolene) nutrients, hydrogels, and phytohormones may provide novel approaches to improve plant tolerance against abiotic stress-induced damage. Moreover, for plant breeders and molecular biologists, it is a challenge to develop cotton cultivars that can tolerate plant abiotic stresses while having high potential NUE for the future.
