The Results showed Nwewya was the most potent cultivar, since it gave the highest yield (5.31t.h-1) biological yield (13.40 t.h-1) Harvest index (39.12{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d})  . The best sowing date was 1st, November, as it manifested the highest yield (6.72 t.h-1 ), biological yield (19.98 t.h-1), weight of 1000 seeds (37.57g), Number of fertile spikes (485.40), Neweya wheat cultivar sown on 1st, November was the most effective treatments, they gave the highest yield (7.80 t.h-1).
