| Abstract | ||
| Two field experiments were carried out on sandy soils atthe farm of El-Sharawy in EL-Bostan area, Noubariazone, Governorate of Elbeheira(Lat. 30° 43' 22.01" N, Longit. 30° 16' 44.50" E), Egypt, during two summer seasons of 2013 and 2014 on maize plants (c.v. tri- hybrid 354) to study the effects of phosphorus and sulphurapplication rates on yield and grain quality of maize. The experiment was laid out in a split plot design with three replications assigning phosphorus levels in the main plots and sulphur levels in sub-plots. The results of this study revealed that application of phosphorus and sulpher and their combinations had significant effects on most of the studied characters in favor of the combination treatment. Allthe studied characteristics except ear diameter were significantly increased by increasing both P and S fertilizers and the higher rate of 30 kg P2O5/fed or 150 kg S/fed. resulted in maximum plant height (2.82or 2.71m), cob weight (238 or 220 g), 100-grain weight (38.70 or 36.63g), grain yield (4473 or 4151 kg/ fed) and protein % (12.96 or 12.01) respectively as compared with the other rates . Application of P-fertilizer and sulpher in combination gave higher values and 30 kg P2O5 +150 kg S/fed. Surpassed the other combinations showing that application of 30 kg P2O5/fed + 150 kg S fed-1is a good formula for achieving bettermaize crop with better quality. | ||
