to investigate the effect of seed rate and Variety of wheat (Triticum aestivum L.) on grain productivity under New Halfa environment. The treatments consisted of three seed rates (119kg/ ha, 143kg/ ha and 167kg/ ha) and two cultivars (Condor (early mature) and Bohin (medium mature). A complete randomized block design (CRBD) with four replications was used. The results revealed that the lesser seed rate (119 kg/ ha) had a lower grain yield compared with the mid seed rates (143kg ha-1) or highest seed rate (167kgha-1). Cultivars had significant differences in the total seed yield. Condor gave the highest seed yield. It could be concluded that the seed rate of 143 kg or 167 kg/ha recommended to improved seed yield in New Halfa area of Sudan. Contribution/Originality:This study is one of the very few studies which have investigated the effect of seed rate and Variety of wheat (Triticum aestivum L.) on seed yield under New Halfa environment, Sudan.
