The Rahad Agricultural Scheme (Sudan) is devoting 1680 ha to forage production for the support of about 10,800 head of dairy cattle. Distribution of 400 tenancies, of 4.2 ha each, started in the 1982/83 season. On-farm trials (OFT) are an integral part of the research project aiming at the improvement of the dairy production systems in the scheme. The primary objective set for OFT is to help researchers develop a realistic understanding of the traditional production system as well as the identification and introduction of practical ways for improvement. In the first year, five tenants were selected to participate in OFT. Three were chosen for the purpose of evaluating forage yields and crop management practices, whereas the other two were identified for the evaluation of both forage and milk production. Results indicated inefficient utilization of the produced forage, although tenants are capable of getting reasonable yields. Many practical reasons were found behind such a behaviour. In this respect, OFT served as a useful technique for complementing information collected about farmers' practices through other means.
