Wheat production in Sudan increased significantly in 1991/92, due to a combination of factors: favorable weather; input availability, and the Government\92s interest and investment in research and transfer of technology. Despine an 18% decrease in the total area planted to wheat, overall production was up by 50% to reach an all-time record of 0.865 million tones. This has made Sudan self-sufficient in bread wheat for the first time. Average yields increased by 87%, 107% and 46% in Gezira, Rahad and the Norther State, respectively. In on-farm demonstrations in major production areas, farmers who had adopted improved production packages achieved 9-100% increases in yield. The adoption studies in Gezira high-lighted the importance of extension, seeding date, preparation and leveling of seedbeds, the use of seed drills and seeding methods, irrigation and water management, and a shorter period between seeding and first irrigation. In backup research, in multi-location testing, 106 lines were selected for further evaluation for heat-tolerance and 70 lines for tolerance of moisture stress. In crop physiology studies, it was found that with holding water at the tillering stage reduced yield by 14%. Studies on population dynamics of aphids (green bug) and their predators Chrysopids and Cydonia were carried out. The economic threshold for chemical control of aphids on wheat was determined at 35% level of infestation. In weed control, the critical stage for effective weeding was found to be between four and six weeks from planting.
