Abstract
Two field experiments were carried out at gemiza (ARS), alsantah, algharbiah, during 2012 and 2013. The aim of the study was to evaluate the performance of SC167 and T.W.C. 353 maize crosses under different rates of NPK. Fertilizers were tested across soil application (SA) at (5 treatments) and foliar application (FA) at (5 treatments). All the agricultural treatments were runned as usual. A split split plot design was used. Seventeen traits were studied. Such traits were distributed at 4 groups; firstly morphological traits (5), secondly: ear traits (5), thirdly: grains/ ear traits (5) and grain yields traits (2). The obtained results could be summarized as follows: Main effects as well as first order interactions significantly affected most studied traits. The most recommended independent factor treatments for superior grain yield/fed were S.C.167 {u00D7} SA 60% NPK {u00D7} FA40% NPK or T.W.C.353 {u00D7} SA 100% NPK {u00D7} FA 40 % NPK. The first order interactions among the levels of the three studied factors seemed to be the most acceptable combinations for excellent grain yield / fed. Signifcancey was completely absent as respect to second order interaction with all studied traits, except only grain yield / fed. The superior combinations were S.C.167 {u00D7} SA100% NPK {u00D7} FA 80% NPK and T.W.C. 353 {u00D7} SA 80% NPK {u00D7} FA 40% NPK. Most of correlation coefficients were positive and significant
