| Income and risk aspects of wheat-fallow cropping systems are analyzed in western North Dakota. A wheat yield trend estimation model based on county yields (1950-77) is developed using independent variables of year, annual precipitation, acres of nonfallowed wheat and a dummy variable for fallow and nonfallow practices. The year-to-year change in wheat yields on fallowed and nonfallowed land indicates that summer fallow is becoming less desirable economically. Based on 1980 costs and yields, summer fallow maximizes returns to land at low yields, low wheat prices, and high nitrogen prices. Income variability is reduced under summer fallow. |

| Net farm income of participants in the North Dakota Farm Business Management Education Program increased with years of enrollment both in absolute terms and compared to peer group benchmarks. Median net farm income increased $7,829 and $14,191 between the first and fifth year of enrollment for all farms in the program and a subset of farms with five consecutive years of records starting with the first year of enrollment, respectively. Net farm income by year of program participation was compared to a benchmark median net farm income for the same geographic region, calendar year, and farm type in an attempt to isolate the affects of management from weather and other exogenous factors. Net farm income as a percent of benchmark increased 17.5 percentage... |

| Data from North Dakota farmers are used to develop regression equations estimating seasonal use of farm operator labor and management time by farm size. Management time has a large fixed component and increases linearly with farm size. Annual labor supervision time per man-month supervised increases when more than 15 man-months of hired or family labor are used. |
