Abstract
Modes maize hybrids need to high amounts of nitrogen, phosphorus and potassium;
therefore, two field experiments were conducted at the Experimental Farm of Sids
Agricultural Research Station, ARC, Beni-Suef Governorate, Egypt during the two successive
seasons of 2015 and 2016 to evaluate the effect of three NPK levels, i.e., 80/6/10, 120/12/20
and 140/18/30kg N, P2O5 and K2O/fad , respectively under four maize hybrids, namely, white
single cross 10, white three way cross 128, yellow single cross 168 and yellow three way
cross 368. Results showed that white single cross 10 gave the highest values of maize growth,
yield and yield components as well as NPK uptake in grains and/or stover, except 100 grain
weight and NPK concentration in grains and stover which were not affected. On the other
hand, yellow three way cross 368 possessed the lowest values. The highest dose of NPK
fertilizers produced the highest growth traits, yield and yield components and NPK uptake.
The number of rows/ear, number of grains/row and NPK concentration in grains and stover.
The white single cross 10 when supplied with 140/18/30kg N, P2O5 and K2O/fad produced the
highest values of growth, yield and yield components traits. The lowest values were exerted
under yellow three way cross 368 when received 80/6/10kg N, P2O5 and K2O/fad, respectively.
