Two field experiments were carried out at Gemiza (ARS), during 2012, 2013. The aim of the study was to evaluate the performance of S.C.167 and T.W.C. 253 maize under the use of different rates of NPK. Fertilizer were tested cross (Cs) , soil application (SA) and foliar one (FA). All the agriculture treatments were used as usual. A split split plot design was used. five traits were studied. Such traits were distributed at ear length, ear diameter, ear height, cob. Weight, and shilling percentage . The obtained results could be summarized as follows : - Crosses, soil application and foliar application of NPK signifcantly affected most studied traites except ear height, cob. weight, and shilling percentage . - Significancey was completely absent as respect to first and  second order interaction with all studied trait but the superior vlues were produced from combination (T.W.C. 253 × 80% NPK (S.A.)),  (T.W.C. 253 × 80% NPK (F.A.)) and (80% NPK (S.A.) × 40% NPK (F.A.))
