1. Long-term Crop Rotation Diversity Effects on Soil C and NThe objective of this study was to evaluate the effects of nitrogen (N) fertilizer level and crop rotation diversity on soil organic carbon (SOC) and N stocks from a 34-yr study located in eastern Nebraska. Seven crop rotations (three continuous cropping systems; two 2-yr crop rotations, and two 4-yr crop rotations) and three N levels were compared. Soil samples were taken to a depth of 60-inches. Differences in SOC stocks were largely confined to the 0 to 3-inch depth with greater SOC (P =... M. Schmer, V. Jin, B. Wienhold, G. Varvel |
2. 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 |
3. 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.

4. 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.

5. 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...

6. Developing Nitrogen and Phosphorus Fertigation Strategies in CottonSubsurface drip irrigation (SDI) is becoming a popular option for maximizing the water use efficiency of cotton (Gossypium hirsutum), especially in semi-arid environments of the Midsouth and Western United States. In the Texas High Plains where underground water resources from the Ogallala Aquifer are rapidly declining, there is increased adoption of water conservation technologies like center pivot and drip irrigation. In addition to increased water efficiency, drip irrigation allows... K. Lewis, H. Valencia, T. Roberts, J. Burke, G. Ritchie |
