Abstract
two field experiments werw carried out at shermsah, el-zarka center domitta governorate, egypt, in the two successive summer seasons of 1992 and1993 to study the effect of nbk fertili-zation levels and their interactions on growth and yield of maize cultivar.
One of the problems faced by growers of corn to determine the quantities of fertilizer nitrogen and phosphorus and potassium the necessary Camel individual modern (individual 10) to raise the productivity per acre and the impact of these quantities on Alnamwa to shoot , yield and its components as well as to know the extent of shareholding of these fertilizers in raising the amount of protein in the corn kernels . For this purpose, set up two experiments in Haklitin Chermessah - Center Alzeraca - Damietta Governorate in the summer season for the years 1992.1993.
The experiment was designed in a split plot twice in four replications where the main pieces included on the rates of nitrogen fertilization rates following : -
1) 75 kg nitrogen per acre.
2) 90 kg nitrogen per acre.
3) 105 kg nitrogen per acre.
4) 120 kg nitrogen per acre.
Included cutting naughty first to add phosphate fertilizer rates , namely: -
1) without fertilization phosphate .
2) 15 kg P 2 O 5 per acre.
3) 30 kg P 2 O 5 per acre.
