Wheat is a strategic crop in Sudan. It is produced exclusively under irrigation during the short winter season between November and March. Bed planting is proven in many parts of the world to reduce the cost of production and irrigation water. A field experiment was conducted for two seasons (2001 and 2002) with modification of an old planter to perform ridging and sowing in one operation. The bed planting treatment was compared with the recommended seed drill on flat and with the traditional manual broadcasting plus ridging to 80 cm. In the second season the hoe furrow openers of the bed planter were replaced by disc type and more seed rates were tested. Water use was monitored for the two seasons. Results showed that bed planting resulted in significantly lower yields compared to the other treatments in the first season. In the second season there were no significant differences in grain yields for all the treatments. However, lower seed rate for bed planting resulted in higher yields compared to bed planting with high seed rate. Regarding irrigation water application, the bed planting treatment had the lowest irrigation water application followed by the broadcasting plus ridging and drilling on flat in both seasons. The bed planting irrigation water use efficiency (IWUE) was the lowest in the first season. However, with lower seed rate and the bed planter improvement in the second season bed planting resulted in the highest IWUE. Therefore, bed planting could be considered as one of the methods for wheat production in Sudan's Vertisols with water savings provided that suitable seeding machines are made available and an optimum seed rate is determined.
