Abstract
Two field experiments were conducted at Mallawy Agricultural Research Station, Agric. Res. Center, El-Minia Governorate in summer seasons of 2006 and 2007 consecutively to study the effect of soil and foliar application of superphosphate and potassium sulfate on maize yield and its attributes and contents of N, P and K nutrients in ear leaf and kernels. Results indicated that foliar application of superphosphate at 10% concentration was significantly better than all other foliar applications involved in the current investigation in respect to kernel yield, ear length and ear diameter in the first season of (2006). Foliar application of potassium sulfate at 5% concentration was better than any other foliar application used in this investigation for producing kernel and ear yields in the second season of (2007). Foliar application of both superphosphate and potassium sulfate at 10% concentration gave the highest significant increase in N content in ear leaf and kernels in the second season of (2007).
