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 Survey of wild oats and other weeds in North Dakota, 1978 and 1979(1981)This survey of wild oats and other weeds was conducted to obtain information needed in order to determine the benefits from diallate and triallate for wild oats control. Diallate is being reviewed by EPA as part of the Rebuttable Presumption Against Registration (RPAR) process and triallate is under consideration for RPAR. Pesticides are considered for RPAR review when there is information indicating possible health or environmental hazards. Reregistration of RPAR pesticides is dependent upon rebuttal of the hazards and/or a favorable benefit-risk analysis. Benefits can be actual or potential benefits so the benefits from herbicides for wild oats control is dependent upon the extent of the wild oats problem as well as present usage of herbicides for wild oats control. This weed survey will not only provide information on infestations for present herbicide benefit analysis. but will also serve as a basis for determining weed population shifts in the future. Weed surveys give valuable information on the location and extent of infestation by various species which is important to development of weed prevention and control systems.Item Comparison of Agar-Gel Immunodiffusion with Other Serological Tests for Diagnosis of Bovine Brucellosis(North Dakota State University, 1980)Item A summary of the synonomy of leafy spurge(North Dakota State University, 1980)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 Growth and survival of shelterbelts(North Dakota State University, 1980)The need for trees in the Great Plains was recognized during settlement in the late 1800's. The Timber Culture Act of 1873 provided for planting a timber culture entry of 40 acres for each quarter section (160 acres) of homestead. The act was amended several times to reduce acreage planted to trees. The Clarke-McNary Act of 1924 provided Federal assistance that made it possible for landowners to purchase planting stock at cost. Governmental programs were developed in the 1930's to help relieve the effects of drought in the Great Plains. The Shelterbelt Program of 1935-1942 (later known as the Prairie States Forestry Project) was one of these programs. The purpose of the Shelterbelt Program was twofold: (a) the planting of windbreaks throughout the eastern plains to reduce wind erosion and (b) to provide relief employment. The program was administered by the U.S. Forest Service until 1942, when responsibility was transferred to the Soil Conservation Service. The purpose of the study was to inventory 20 Prairie States Forestry shelterbelts in Cass, Barnes and Ransom counties of southeastern North Dakota. The inventory would include tree and shrub species, growth data, vigor and the incidence and types of diseases and insects. The shelterbelts were chosen at random to obtain variation in species, orientation and planting sites. These belts ranged in length from one-quarter mile to one-half mile and from three to 20 rows in width.Item Control of Reproductive Phenomena in Cycling and Noncycling Ewes with Various Exogenous Hormonal Compounds(North Dakota State University, 1979)Steadily declining numbers of breeding sheep accentuate the need for critically examining and improving production practices to maintain lamb production and preserve marketing and processing facilities. Alterations of breeding management to incorporate exogenous hormonal compounds is one possible means of increasing lamb production per ewe. Sheep usually mate when periods of light are less than 14 hours. The normal breeding season at this latitude begins in early August and lasts until mid-January. During this period daylight length and possibly temperature play a role in initiating changes in hormonal secretion which in tum regulates estrual activity. Improved seasonal breeding by synchronization of estrus in the ewe flock and more repeatable out-of-season breeding are desirable to increase year around lamb production and reduce seasonal fluctuations in cost. Synchronization or stimulating ewes to exhibit estrus and conceive could result in: 1) earlier lambing dates, 2) a shorter lambing season, 3) reduced labor requirements during lambing, and 4) a more uniform lamb crop. Out-of-season breeding, as the term implies, is breeding ewes out of the normal breeding season to produce fall lambs. This practice could be utilized to increase total lamb production. By stimulating ewes with exogenous hormones in the spring of the year, out-of-season breeding can occur and a potential fall lamb crop produced. The series of experiments reported herein were conducted to evaluate the effects of various exogenous hormonal compounds on the regulation of estrual activity in both cycling and noncycling (anestrous) ewes.Item Effect of Nitrogen-Fertilized Wheat on Water Loss from Soils of the Barnes Catena(North Dakota State University, 1979)Item Characterization of Coal Overburden and Strip-Mine Spoils in North Dakota(North Dakota State University, 1978)Item Evaluation of North Dakota's First Rural Water System: Research Project Technical Completion Report(North Dakota State University, 1976)Item Calf Scour Study: Summary 1975-77(North Dakota State University, 1978)Item Fertilization of wheat, corn, and grass-legume mixture grown on reclaimed spoilbanks(North Dakota State University, 1978)The efficacy of phosphorus and nitrogen soil tests developed for undisturbed soils in North Dakota to predict deficiency of these nutrients and the related corrective measures using commercial fertilizers was evaluated on reclaimed sites with three crops over a 2-year period. Yield responses of wheat, corn, and grass-legume to application of phosphorus and nitrogen fertilizers confirmed a deficiency or sufficiency of each nutrient. The nutrient status predictive capability of the soil tests is considered suitable for reclaimed sites. Rate of nutrient application to correct the deficiency, however, may require adjustment from those utilized for undisturbed sites.Item Crop Curves for Water Balance Irrigation Scheduling in S.E. North Dakota(North Dakota State University, 1977)Item Phage and phage-like particles of Bacillus pumilus from an animal waste lagoon(North Dakota State University, 1976) Berryhill, David Lee, 1944-In this report (a portion of a thesis presented by K. E. Irmen in partial fulfillment of the requirements for the M.S. degree in bacteriology at North Dakota State University), we describe a new temperate bacteriophage for a Bacillus pumilus lagoon isolate. In addition, the strain lysogenic for the new phage and the B. pumilus type strain (ATCC 7061) both harbor inducible particles which resemble "killer particles" reported for other Bacillus strains (1, 12). B. pumilus ATCC 7061 also produces a second type of phage-like particle upon induction.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.Item Runoff and erosion from snow-melt on surface mined sites in western North Dakota(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.
