Item On-farm irrigation scheduling evaluations in southeastern North Dakota(North Dakota State University, 1980)Item Water management relationships for irrigated pinto beans(North Dakota State University, 1976)Item Water balance irrigation scheduling based on Jensen-Haise equation : software for Apple II, II+, and IIE computers(North Dakota State University, 1984)Developments in applied methods for estimating crop water use (evapotranspiration) have made it possible to estimate root zone soil moisture deficits in irrigated fields with reasonable accuracy. A zero soil moisture deficit (SMD=O) implies that the root zone storage capacity (influenced by soil textures and rooting depths) is filled to "field capacity." Day-to-day crop water use produces a water deficit, whereas irrigations and rainfalls (when they occur) reduce the deficit. Irrigation scheduling implies that at some level of water deficit an irrigation system must be started and run until the prevailing deficit is reduced to lower levels if near maximum yield is the production goal. The following material includes an algorithm for irrigation scheduling, source code with documentation (written in Applesoft Basic), and a users guide.Item Crop Curves for Water Balance Irrigation Scheduling in S.E. North Dakota(North Dakota State University, 1977)Item An Analysis of Irrigation Farming in the Warwick-McVille Project Area(North Dakota State University, 1979)"Report of the "MIP" interdisciplinary research team, North Dakota Agricultural Experiment Station, North Dakota State University of Agricultural and Applied Science in cooperation with Bureau of Reclamation, United States Department of the Interior and Garrison Conservancy District."Item An Analysis of Irrigation Farming in the Oakes-LaMoure Project Area(North Dakota State University, 1977)The Marketing Irrigation Production (MIP) interdisciplinary research team was formed to determine the best combination of irrigated crops, dryland crops, and livestock enterprises and to evaluate the market potential of agricultural production from the Garrison Diversion Irrigation Project. The MIP team consists of research scientists from Agricultural Economics, Agronomy, Animal Science, Horticulture, and Soils departments at North Dakota State University. The Garrison Diversion Irrigation Project was divided into three general areas: North, Central, and South. The criteria for dividing the district into three areas were length of growing season, amount of rainfall, current farming practices, and present and potential markets. The Northern area, composed of the Souris Loop and Karlsruhe irrigation areas as shown in Figure 1, contains approximately 116,000 acres in parts of Bottineau and McHenry counties. The 74,670 Central area includes all land in the Lincoln Valley, New Rockford, and Warwick-McVille irrigation areas, covering parts of Sheridan, Eddy, Benson, and Nelson counties. The Southern area, composed of the LaMoure, East Oakes, and West Oakes irrigation areas, encompasses 59,330 acres in parts of Stutsman, LaMoure, Dickey, Sargent, and Ransom counties. The Oakes-LaMoure area covered in this report is the first irrigation area scheduled to receive water from the Garrison Diversion Irrigation Project. Subsequent reports will cover the other irrigation areas.
