Two field experiments were carried out at the experimental farm of Al-Arish Agricultural Research Station, Governorate of South Sinai, Agricultural Research Centre (ARC) in summer seasons of 2006 and 2007 to investigate the effectiveness of different rates of nitrogen fertilizer 60, 90, 120 kg/fed and ordinary super phosphate zero, 15, 30 kg P₂O₅/fed incorporated with 10 m³ chicken manure/fed on yield of maize (Three Way Cross 324 cultivar) and its attributes under Al-Arish soil conditions. The results showed that application of chicken manure at the rate of 10 m³/fed had similar effect as application of 15 or 30 kg P₂O₅/fed together with 10 m³ chicken manure/fed in kernel yield and its relevant attributes. Application of 15 kg P₂O₅/fed + 10 m³ chicken manure/fed had significant effect on plant height and this combined rate was better than 30 kg P₂O₅/fed + 10 m³ chicken manure/fed in kernel yield and its relevant attributes. The interaction of the two factors under investigation had insignificant effect on the agronomic parameters investigated in these two experiments. Increasing nitrogen rate from 60 to 90 kg/fed caused positive significant effect on N and P contents in kernels. Additional increase in N rate caused significant effect on P and K contents in kernels.
