Summary: An experiment was conducted for two seasons (1999-2001) at Hudeiba Research Station, Northern Sudan, to study the effect of sowing date and cultivar on yield and yield components of maize (Zea mays L.). Three open-pollinated cultivars, namely Hudeiba-l, Hudeiba-2 and mojtamaa-45 were sown at three sowing dates: October 1, November 1 and December 1. The design was a split-plot replicated three times with sowing date as main plots and cultivar as sub-plots. The results showed that sowing date had a significant effect on yield and yield components of the crop. October sowing (4,097 kg /ha) outyielded November and December sowings by 36.5 and 53%, respectively. The cultivars grown varied significantly in their yield potential. Hudeiba-1 and Hudeiba-2 gave similar yields but exceeded Mojtamaa-45 by 24.7 and 25.5%, respectively. Grain yield of the crop was positively correlated with cob yield, 1000-seed weight and number of cobs/m2 (0.807***, 0.732*** and 0.468***), respectively. The study indicates that substantial grain yield of maize can be obtained during the winter season in Northern Sudan in contrast to other findings in other parts of the country. Therefore, it was concluded that maize could be an alternative winter cash crop for farmers in Northern Sudan
