Morphology And Biomass Production Of Prairie Cordgrasson Marginal Lands, A. Boe, V Owens, J. Gonzalez-Hernandez, J. Stein, D. K. Lee, B. C. Koo

Agronomy, Horticulture and Plant Science Faculty Publications

Prairie cordgrass (Spartina pectinata Link.) is indigenous throughout most of the continental United States and Canada to 60°N latitude and is well suited to marginal land too wet for maize (Zea mays L.) and switchgrass (Panicum virgatum L.). Evaluations of prairie cordgrass in Europe and North America indicated it has high potential for biomass production, relative to switchgrass, in short‐season areas. Our objective was to describe morphology and biomass production and partitioning in mature stands of ‘Red River’ prairie cordgrass and determine biomass production of natural populations on marginal land. This study was conducted from 2000 to …

Best Management Practices For Corn Production In South Dakota: Corn Grain Harvest, Daniel S. Humberg, Richard E. Nicolai, Kurtis D. Reitsma

SDSU Extension Circulars

Corn (grain) harvest can begin when grain moisture drops below 30%. However, most producers will allow corn to dry in the field until grain moisture is between 18 to 25%. Harvesting corn when grain moisture levels are high can result in excessive drying costs, kernel damage, and harvest loss from improper threshing. Allowing corn to stay in the field too long can result in excess harvest loss from stalk lodging, ear drop, or kernel shattering. An optimal harvest depends not only on the condition of the crop but also on the proper maintenance and adjustment of harvest and grain handling …

Best Management Practices For Corn Production In South Dakota: Corn Insect Pests, Michael A. Catangui, Billy W. Fuller, B. Wade French

SDSU Extension Circulars

Historically, the major corn insect pests have been corn rootworms (northern and western), European corn borer, and black cutworm. Bt-corn hybrids are effective against most of these pests. However, Bt-corn hybrids are not effective against corn leaf aphid, corn root aphid, sap beetles, corn rootworm adults, grasshoppers, white grubs, wireworms, seed corn beetle, and seed corn maggots. These insect pests can reduce corn yields. This chapter discusses the management and biology of important corn insect pests commonly observed in South Dakota.

Best Management Practices For Corn Production In South Dakota: Soil Fertility, David E. Clay, Kurtis D. Reitsma

SDSU Extension Circulars

Corn requires sufficient amounts of at least 14 nutrients for optimal production (fig. 7.1). Soil fertility strategies should consider soil residual plant nutrients, cost of fertilizer relative to the value of corn, and management techniques that increase efficiency.

Best Management Practices For Corn Production In South Dakota: Corn Diseases In South Dakota, Martin A. Draper, Marie A. Langham, Sharon Clay, Bradley E. Ruden

SDSU Extension Circulars

Corn diseases can be separated into 1) seed and seedling diseases, 2) root-infecting nematodes, 3) leaf diseases, 4) rusts, 5) stalk rots, and 6) ear and grain molds. Yield losses can result from diseases directly reducing yields or from harvestability, spoilage, or marketing and/or use issues associated with mycotoxin contamination. See Table 9.1 for corn disease management information. Attention to optimal seed quality, hybrid selection, seed treatments, weed and insect control, crop rotation, soil fertility, irrigation, and prompt harvest can reduce disease impacts. This chapter discusses aspects of recognizing and managing South Dakota corn diseases.

Biomass And Seed Yields Of Big Bluestem, Switchgrass, And Intermediate Wheatgrass In Response To Manure And Harvest Timing At Two Topographic Positions, Dokyoung Lee, Vance N. Owens, Arvid Boe, Bon-Cheol Koo

Agronomy, Horticulture and Plant Science Faculty Publications

A principle attribute of perennial grasses for biomass energy is the potential for high yields on marginal lands. Objectives of this study were to compare biomass and seed production of intermediate wheatgrass (Thinopyrum intermedium [Host] Barkworth and D.R. Dewey), big bluestem (Andropogon gerardii Vitman), and switchgrass (Panicum virgatum L.) as affected by harvest timing and manure application on two topographic positions (footslope and backslope). Footslope is the hillslope position that forms the inclined surface at the base of a slope and backslope forms the steepest, middle position of the hillslope. Grasses were harvested for biomass at anthesis …

Mapping Of Photoperiod-Induced Growth Cessation In The Wild Grape Vitis Riparia, Amanda Garris, Lindsay Clark, Chris Owens, Steven Mckay, James Luby, Kathy Mathiason, Anne Fennell

Agronomy, Horticulture and Plant Science Faculty Publications

In grapevines (Vitis spp.), the timing of growth cessation in the fall is an important aspect of adaptation and a key objective in breeding new grape cultivars suitable for continental climates. Growth cessation is a complex biological process that is initiated by environmental cues such as daylength and temperature, as well as water and nutrient availability. The genetic control of growth cessation in grapevines was studied by mapping quantitative trait loci (QTL) in a hybrid grape population. An F2 mapping population was developed by selfing a single F1 plant derived from a cross between an accession of the North American …

Selection Of Winter Wheat Mutant Lines Resistant To Drought Stress, Brian Kontz, Sean Franklin, Charles Brunel

The Journal of Undergraduate Research

Mutated winter wheat lines were screened for improved drought resistance compared to the wildtype by withholding water for 3 weeks after 9 weeks of normal growth, and noting their responses upon re-watering. Of the 146 mutants grown, 73% were either killed due to water stress or showed poor recovery, while 27% recovered better than the wildtype line. This experiment enabled the selection of candidates for further investigation to better understand the genetic basis of drought tolerance in winter wheat.

Effects Of Stratification, Warm Treatment, And Mechanical And Acid Scarification On The Emergence Of Yellow-Flowered Alfalfa (Medicago Sativa Subsp. Falcata) Seeds, Diane Narem

The Journal of Undergraduate Research

Yellow-flowered alfalfa (YFA) has great potential to improve rangelands in the Northern Plains. Greater than 99% of YFA seeds from soil were viable but less than 4% germinated under standard laboratory conditions. The objective was to determine if low germination was due to physical or physiological seed dormancy. The experiment utilized a random complete block design with two trials, eight replications per trial. Each replication consisted of ten treatments plus a control, four stratification treatments consisting of a combination of two temperatures (-5°C, -20°C) and two durations (48 hr, 72 hr), one warm treatment (4 min, 60°C), four sandpaper scarification …

Time And Temperature Requirements For Effective Removal Of High Molecular Weight Rna From Winter Wheat Genomic Dna With Licl, Benjamin Meyerink, Ryan Geraets

The Journal of Undergraduate Research

Numerous protocols are available for the isolation of plant genomic DNA. Often times, these protocols utilize a wide variety of solutions. The primary purpose of this project was to examine the use of LiCl for the removal of RNA contaminants within genomic DNA samples and its dependency on incubation time and temperature. Our results indicate that LiCl is sufficient for the removal of high molecular weight RNA contaminants from genomic DNA. In addition, our results illustrate varying incubation times with LiCl yield minimal differences in the recovery of genomic DNA and the removal of RNA contaminants. Alternatively, different incubation temperatures …
