These work was undertaken at the Agricultural Research
Experimental Center of the Faculty of Agriculture, l4oshtohor
to evaluate three new Synthetic varieties viz, Moshtohor-l,
2 and 3. These new varieties as well a two local ones,
i.e., Nab El—Gamal and Cairo—I were evaluated under different
nitxogen fertilization levels during the two Successive
seasons 1986 and 1997. The differences among varieties
were significant for all traits except for number of kernels
per rowe Moahtohor-1 produced the highest grain yield per
plant and outyjelded Nab Rl—Gamal, Cairo-i, Moshtohor—2
and 3 by 16.77%, 8.19%, 10.89% and 7.30%, respectively.
Nitrogen f.rilization had significant effects on
grain yield per plant and the best treatment was 90 kg
N/taddan. Whereas, the other studiad traits were not signif i—
canti.y affected by nitrogen treatments.
