Spring‐Applied Corn Herbicides Impact Fall‐Planted Cover Crops In South Dakotaa, Sydney Pridlie, S. A. Clay, G. Shaffer Sep 2020

Spring‐Applied Corn Herbicides Impact Fall‐Planted Cover Crops In South Dakotaa, Sydney Pridlie, S. A. Clay, G. Shaffer

Agronomy, Horticulture and Plant Science Faculty Publications

Early spring herbicide applications can have residuals that impede fall‐planted cover crop growth. A greenhouse study examined radish (Raphanus sativus L.) or rye (Secale cereale L.) growth in silty clay loam (southeastern South Dakota) and silt loam (north‐central South Dakota) where corn herbicides had been applied about 120 d prior to collection. S‐metolachlor, acetochlor, flumetsulam, metribuzin, bicyclopyrone + mesotrione + S‐metolachlor + atrazine, and primisulfuron‐methyl + prosulfuron (northern site only) were applied at the suggested timing and highest recommended rate and planted to corn (Zea mays L.). Two 11‐cm diam. soil cores to a 10‐cm …


Selection Signatures Across Seven Decades Of Hard Winter Wheat Breeding In The Great Plains Of The United States, Habtamu Ayalew, Mark E. Sorrells, Brett F. Carver, P. Stephen Baenziger, Xue-Feng Ma Sep 2020

Selection Signatures Across Seven Decades Of Hard Winter Wheat Breeding In The Great Plains Of The United States, Habtamu Ayalew, Mark E. Sorrells, Brett F. Carver, P. Stephen Baenziger, Xue-Feng Ma

Department of Agronomy and Horticulture: Faculty Publications

Classical plant breeding has been instrumental in changing the genetic makeup of crop plants for better ecological adaptation and improved quality. This paper provides insights of the genomic changes effected in hard winter wheat (Triticum aestivum L.) through decades of breeding and selection in the Great Plains of the United States. Population structure and differentiation analyses were conducted on 185 wheat cultivars released from 1943 to 2013. Cultivars were grouped into four distinct clusters using discriminant analysis of principal components (DAPC). One of the clusters was unique in that 15 out of the 18 individuals were recent releases (2000–2010), …

Arkansas Wheat Cultivar Performance Tests 2019-2020, R. E. Mason, R. G. Miller, D. E. Moon, J. P. Kelley, J. Carlin

Arkansas Agricultural Experiment Station Research Series

Wheat cultivar performance tests are conducted each year in Ark- ansas by the University of Arkansas System Division of Agriculture’s Arkansas Agricultural Experiment Station, Department of Crop, Soil, and Environmental Sciences. The tests provide informa- tion to companies developing cultivars and marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for small-grain producers. The tests are conducted at the Northeast Research and Extension Center at Keiser, the Vegetable Substation near Kibler, the Lon Mann Cotton Research Station near Marianna, the Newport Extension Center near Newport, the Rohwer Research Station near Rohwer, the Pine …

Department of Agronomy and Horticulture: Faculty Publications

The Agricultural Production Systems sIMulator (APSIM) was used to evaluate two alternative approaches for extending the cover crop growing window into corn (Zea mays L.) and soybean (Glycine max L.) crop rotations in Nebraska, USA.We evaluated how: (i) shifting corn planting dates (mid-April to early-June) and (ii) altering comparative relative maturity (CRM) corn hybrids (80 to 115 days) influence cover crop biomass and corn yields over a 30-year period. The APSIM model was tested using experimental data and was then used to simulate a range of cover crop planting and termination scenarios. Our results showed no significant yield …


Summaries Of Arkansas Cotton Research 2019, Fred Bourland Sep 2020

Summaries Of Arkansas Cotton Research 2019, Fred Bourland

Arkansas Agricultural Experiment Station Research Series

Statewide, temperatures and precipitation were mostly above average (https://www.weather.gov/lzk/cli2019atxt.htm). The 2019 season was the wettest since 2015, and the 7th wettest on record. The wettest month was May, and the driest month was September. By average temperature, the coldest month was January, and the warmest month was August. Considering departures from normal, the most significant warmth occurred in September, which was 7.0 degrees above average. Many fields were muddy or underwater, given a lot of rain early in the year, and extensive river flooding (including the historic Arkansas River flood). It was far too wet in some areas …

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Edamame is a food-grade soybean that is harvested at the green-immature stage (R6) and sold fresh or frozen for consumption after steaming or boiling. Limited studies have been conducted on high-temperature sterilization of edamame in cans and on acid preservation of edamame. The objectives of this study were to evaluate the color retention and texture of edamame when pasteurized in acidic brine as compared to boiling, to assess the effect of sucrose and turmeric addition on acid-treated edamame, and to characterize varietal differences when edamame lines were pasteurized in an acidic brine at either R6 or R8 stage. All studies …


Physiological And Biochemical Responses Of Two Cotton (Gossypium Hirsutum L.) Cultivars Differing In Thermotolerance To High Night Temperatures During Anthesis, Dimitra A. Loka, Derrick M. Oosterhuis Sep 2020

Physiological And Biochemical Responses Of Two Cotton (Gossypium Hirsutum L.) Cultivars Differing In Thermotolerance To High Night Temperatures During Anthesis, Dimitra A. Loka, Derrick M. Oosterhuis

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

Heat stress constitutes a major threat to crop production, and according to climatic projections, night temperatures are expected to increase faster and to a greater extent compared to day temperatures. While extensive research has been dedicated to the effects of higher than optimum day temperatures on cotton physiology, metabolism, and yield, and while heat-tolerant cotton cultivars have been introduced, the responses of such heat-tolerant cultivars to high night temperatures have not been evaluated. The objective of this study was to assess the efficiency of heat-tolerant cultivars to high night temperatures stress by monitoring the physiological and biochemical responses of two …

Slow Movement Of Alkali From Surface-Applied Lime Warrants The Introduction Of Strategic Tillage For Rapid Amelioration Of Subsurface Acidity In South-Western Australia, Gaus Azam, Chris Gazey Aug 2020

Slow Movement Of Alkali From Surface-Applied Lime Warrants The Introduction Of Strategic Tillage For Rapid Amelioration Of Subsurface Acidity In South-Western Australia, Gaus Azam, Chris Gazey

Grain and Other Field Crops Research Articles

Conventional surface-application of agricultural lime takes many years to increase pH deeper in the soil profile, which is a barrier to increased adoption of liming. We conducted a series of experiments to measure the rate of vertical movement of alkali and identify the factors that determine this movement into the subsurface, to evaluate the feasibility of ameliorating acidic subsurface soil using residual (undissolved) lime (CaCO3) at Wongan Hills (30.85°S, 116.74°E) and Merredin (31.48°S, 118.21°E) and to test whether deep tillage and lime incorporation can significantly speed up the amelioration of subsurface soil acidity at Kalannie (30.42°S, 117.29°E). Multiple applications of …

Department of Agronomy and Horticulture: Faculty Publications

The public health crisis and economic recession caused by the COVID-19 pandemic have forced turfgrass industry professionals to re-evaluate standard practices. Minimum costs required to fertilize, irrigate, and mow turfgrasses can be roughly estimated using climate data, turfgrass physiology information, and resource costs. Although the actual minimum costs vary situationally and regionally, mowing golf putting greens optimally requires about US$34 per acre per month, whereas other turfgrass areas cost less than US$11 per acre per growing month. Fertilizer applications to turfgrass cost US$22 or less per acre per growing month. Irrigation costs (water and electricity for pumping) vary widely, with …
