Two filed experiment were conducted from Res. Expt .
Cent., Fac. Agric., Moshtohor Benha. Univ. during 2005/2006
and 2006/2007 growing seasons. To study the effect of bio and
mineral NPK levels(Complete strength C.S, half strength and
quarter strength) and antioxidants treatments (0, Vit. C, Vit E
and mixture Vit. C+E) on growth, yield and yield component
and chemical composition of wheat plants Cv sakha 93.Results
showed that. Studied wheat characters (i.e. growth, yield and
yield component and chemical composition) were positively
affected increased with increasing mineral NPK fertilizer up to
CS and combination with biofertilizers in both seasons. Wheat
grains soaking and spraying with Vit.C at 150 mg/l increased
growth parameters, grain yield components and chemical
composition in wheat plants during in both seasons. The
interaction between CS mineral NPK and biofertilizer with Vit.C
increased growth, yield and yield components and chemical
composition of wheat plants during first and second seasons.
