520 _aA six year experiment at Tel Hadya, Syria, provided data on four rainfed crop rotations: (1) barley-fallow, (2) barley-vetch, (3) wheat-lentil-water melon and (4) wheat-vetch-water melon. "Traditional" rotations (1 and 3 above) were managed as by farmers in the area: "high-input" rotations (2 and 4) incorporated vetch crops for pasture or hay and used "improved" cultural practices and cereal varieties. A linear programming model was used to compute optimal solutions for 36 resource and management scenarios. Farm profits with the "high input" rotations were greater than those of the "traditional" rotations under all comparable resource conditions,
