O. Kheiry, Mohamed Hassan Dahab and Hassan Mohamed Ahmed Alhag Abstract: The current study was aimed to evaluate the effects of three different land leveling techniques (laser scraper, tractor scraper and animal drawn scraper) and two sowing methods on growth and yield of wheat crop were therefore examined in a bid to establish their optimum conditions. The study was performed at Dongola Agricultural Research Farm in Northern State - Sudan. Split plot design with two factors and three replications were used in the study. Results indicated that, variation in land leveling treatment and sowing methods showed a highly significant impact on observed parameters, the mean of plant population for laser scraper, tractor scraper and traditional scraper at mechanical sowing were 385, 370 and 360 respectively. The treatment of laser leveling implement + mechanical sowing, considered as best optimized value for grain yield which is recorded 5 ton/ha. A statistically, there were significant influences of leveling techniques on plant height and total biological yield (P<0.05).
