1. Tillage and Nitrogen Management for Irrigated Sugarbeet Production in Eastern MontanaSugar beet (Beta vulgaris L.) is an important cash crop in the Lower Yellowstone River region. Nitrogen management is very critical while farmers are transitioning sugar beet production from conventional tillage to no-till system. The objectives of this study were to: (i) evaluate the effects of fertilizer-N rate and application timing on sugar beet root yield, sugar content, and quality under conventional and no-till managements, (ii) determine N uptake and N use efficiency (NUE)...

2. Effect of Foliar Zinc Application on Durum and Spring Wheat Grain Yield and QualityZinc (Zn) deficiency represents a common micronutrient deficiency in human populations, especially in regions of the world where staple food crops are the main source of daily calorie intake. Micronutrients like Zn also plays an important role in growth and development of plant thereby affecting crop yield and quality. A two-year field trial was conducted at Sidney, Montana, to investigate the effect of foliar application of Zn on yield and grain quality of spring wheat. Zinc treatment included... F. Etemadi, R. Keshavarz afshar, H. He, S. Zhou, Z. Li, C. Chen |
3. Effect of Soil and Foliar Application of Sulfur, Magnesium, Boron, and Zinc on Root Yield and Sugar Quality in Conventional Till and No Till Sugar BeetField experiment was conducted at the Eastern Agricultural Research Center in Sidney, MT, to determine the effect of S, Mg, B, and Zn on beet yield and sugar quality under conventional and no-till system. Split-plot design was used with 3.6 x 9.1 m experimental plots and four replicates. Tillage was main plot and micronutrient fertilizer was sub-plot. Tillage treatments included conventional and no-till. Fertilizer treatments included SUL4R-PLUS® (Ca & S), SUL4R-PLUS®B+Zn... C. Lim, C. Chen, C. Kowatch-carlson, B. Franck, T. Gross, R. Brown |
4. Soil Properties Affected by Grazing and Tillage of Annual ForagesNo-till (NT) management of annual crop production systems increases precipitation capture and storage. However, compaction with annual livestock grazing and the development of herbicide resistant weeds present challenges to long-term NT. An on-farm study was established in 2016 near Jetmore, KS to investigate the influence of annual tillage with a sweep plow compared to NT in a grazed continuous winter triticale production system. Forage productivity as well as weed density and soil properties... P. Mauler, J. Holman , A. Obour , L. Simon, K. Roozeboom |
5. Lentil Inoculant, Potassium, Sulfur, and Micronutrient Effects on Yield and Protein in the Northern Great PlainsLentil (Lens culinaris Medikus) is an important crop, averaging more than 600,000 ac in MT and ND from 2016-20. However, relatively little is known about inoculant and fertility response in lentil in the U.S. northern Great Plains. The objective of this experiment was to evaluate the effect of rhizobial inoculant formulations (granular and seed-coat) and nutrient additions (K, S, and micronutrients), on lentil growth, yield, and seed protein. This study was conducted at six or seven university... P. Miller, C. Jones, S. Atencio, C. Chen, E. Eriksmoen, S. Fordyce, P. Lamb, M. Ostlie, J. Rickertsen, M.A. Grusak, M. Bourgault, B. Franck, P.

6. Increasing Winter Wheat Grain Yield By Replicating the Management Adopted in High-Yielding Commercial FieldsLarge winter wheat (Triticum aestivum) yield gaps between farmer yields and yield potential in the southern Great Plains indicate the need to improve recommendations of best management strategies to profitably bridge this gap. Many studies have been completed on individual management factors pre-determined by the individual researcher, but we are not aware of studies comparing combination of practices that producers are currently using, which would be more relevant for real-world scenarios....

7. Combined Nitrogen with Magnesium or Zinc Effects on Sugarbeet Yield Sucrose Concentration, and Nutrient Uptake Under Conventional and No-till SystemsSugar beet (Beta vulgaris L.) is an important cash crop in the Lower Yellowstone River valley. Fertility, especially nitrogen (N) fertilizer, management is critical for sugar beet yield and sucrose concentration. While farmers are switching from a conventional tillage method to a no-till system for sugar beet cultivation, nitrogen (N) fertilizer application timing might need to be adjusted. Furthermore, micronutrients may enhance sugar beet yield and sucrose concentration. A two-year... C. Chen, M. Etesami, M. Abdelhamid |
8. Nitrogen Fertilizer and Rhizobium Combinations to Improve Yield and Quality of Mung Bean and Adzuki Bean in MontanaMung bean and adzuki bean are new alternative grain legumes that may be grown in Montana and provide benefits to Montana’s cropping systems by improving long-term diversification and productivity. The objective of this study was to investigate mung bean and adzuki bean response to nitrogen fertilizer and rhizobium combinations to determine the optimum fertilizer management. Two adzuki bean (Organic and O.R varieties) and two mung bean (Organic and L.N varieties) cultivars were grown under... M. Etesami, F. Etemadi, T. Gross, B. Franck, C. Chen, C. Kowatch-carlson, S. Franck |
9. Agronomic Evaluation of Camelina Genotypes Selected for Yield, Oil Concentration, and NUEIn recent years, camelina (Camelina sativa L.) has received global recognition for its role as a biofuel crop and multipurpose addition to cereal-based farming systems in the Northern Great Plains (NGP). The present study objected to investigative the response of selected camelina cultivars, line 229, line 35, line 53, Suneson, and Check1 to nitrogen (N) and sulfur (S) inputs in terms of biomass, yield, seed oil content, and nitrogen use efficiency (NUE) at five nitrogen (N) rates, ranging...

10. Effect of Seeding Rate on Annual Warm Season Forage Yield and Plant StructureDue to the decline of the Ogallala Aquifer and reduced irrigation capacity, there is growing interest in more water-efficient cropping systems in the semi-arid central Great Plains. To support the region’s livestock industry, there is increased interest in forages because they use water more efficiently than grain crops. However, there is insufficient information on summer annual forage seeding rates in the range of environments encountered in the region. The objective of this study was... J. Holman, N. Detter, A. Obour, P. Tamea |
11. Summer Annual Legumes: Yield Potential and Water UseDue to the decline of the Ogalla Aquifer and reduced irrigation capacity, there is a growing interest in more water-efficient cropping systems in the semi-arid central Great Plains. One of the most water-intense crops grown on the semi-arid central Great Plains is alfalfa (Medicago sativa L.). Alfalfa is grown for its nutritive value and protein, which is highly desired by cow/calf, feed yards, and dairies of the central and southern Great Plains. The purpose of this study was to evaluate... J. Holman, N. Detter, A. Obour, L. Haag, K. Roozeboom |
