Short-Term Effects Of Winter Cover Crops On Soil Properties, Yield, And Partial Returns In A No-Tillage Soybean Rotation, Drew Dillon Kirkpatrick
Short-Term Effects Of Winter Cover Crops On Soil Properties, Yield, And Partial Returns In A No-Tillage Soybean Rotation, Drew Dillon Kirkpatrick
Graduate Theses and Dissertations
Cover crops have the potential to provide many benefits including weed suppression, erosion control, and improvements to soil quality. These benefits can be affected by species, biomass accumulation, and management practices. Although large amounts of biomass are good for maximizing benefits, it can result in problems for establishing the subsequent crop. Soybean [Glycine max (L.) Merr.] accounts for over 50% of Arkansas crop hectares annually; therefore, understanding the effect that a cover crop can have on the following soybean crop is crucial to the successful implementation of cover crops within the state. A study was established to evaluate winter cover …
Baseline Sensitivity To Demethylation Inhibitors Fungicides In Cercospora Spp. And Corynespora Spp. In Arkansas Soybeans, Evan Buckner, Alejandro Rojas
Baseline Sensitivity To Demethylation Inhibitors Fungicides In Cercospora Spp. And Corynespora Spp. In Arkansas Soybeans, Evan Buckner, Alejandro Rojas
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Cercospora spp. and Corynespora spp. are two common foliar fungal pathogens in Arkansas and other soybean-producing areas. Two primary diseases caused by Cercospora spp. are Cercospora Leaf Blight (CLB, caused mainly by C. kikuchii) and Frogeye Leaf Spot (C. sojina). Over time, many fungicides used to combat these diseases have become ineffective as the pathogens have developed a resistance to them. The class of the fungicide in question is Triazoles [Demethylation Inhibitors (DMI)–FRAC 3]. Fifteen isolates consisting of Corynespora cassiicola, Cercospora sojina, and Cercospora flagellaris were tested to determine baseline sensitivities using serial dilutions (0, 0.01, 1, 10, 50 mg/L) …
Using Precision Agriculture Field Data To Evaluate Combine Harvesting Efficiency, Justin H. Carroll, Don Johnson, Jeff Miller, Kristofor Brye
Using Precision Agriculture Field Data To Evaluate Combine Harvesting Efficiency, Justin H. Carroll, Don Johnson, Jeff Miller, Kristofor Brye
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Soybeans must be harvested during a limited time period using expensive combines and associated equipment. Maximizing combine field efficiency, the ratio of the actual harvesting capacity to theoretical harvesting capacity, is an important objective of machinery managers. Spatial and temporal yield data from a 2012 CaseIH 8120 Axial-Flow combine equipped with a 9 meter MacDon D-65 Draper header and the Case-IH Advanced Farming System (AFS) yield monitoring system were used to examine field efficiency when harvesting soybean in three Arkansas Delta irrigated soybean fields during the 2015 season. Time efficiencies (TE) in the three fields ranged from 72.9% to 85.8% …
Risk Return Of Farmer-Elevator Contracts For Soybeans And Corn In Arkansas, Marei Undine Houpert
Risk Return Of Farmer-Elevator Contracts For Soybeans And Corn In Arkansas, Marei Undine Houpert
Graduate Theses and Dissertations
In Arkansas the contribution of Agriculture to the states GDP is comparatively high. To help farmer's return risk the grain industry developed several marketing tools to support farmers. Literature in this research field finds different results for different locations, commodities, marketing tools and marketing years. As Agriculture in Arkansas is important for its economy this study focuses on soybeans and corn produced in the fertile north-eastern area of Arkansas that uses Memphis Tennessee as a spot market palace. The examined marketing tools are pre-harvest futures hedges and forward contracts as well as post-harvest storage strategies and minimum price contracts. All …
Comparison Of Prices For 'Organic' And 'Conventional' Grains And Soybeans In The Northern Great Plains And Upper Midwest: 1995-2000, Sherry K. Bertamsen, Thomas L. Dobbs
Comparison Of Prices For 'Organic' And 'Conventional' Grains And Soybeans In The Northern Great Plains And Upper Midwest: 1995-2000, Sherry K. Bertamsen, Thomas L. Dobbs
Economics Pamphlet Series
Price premiums for organic crops drew the attention of increasing numbers of farmers in the Northern Great Plains and Upper Midwest during the 1990s. Continuing low prices for crops grown with 'conventional' farming methods during the late 1990s caused a growing number of farmers to explore the possibilities of switching to organic methods and obtaining organic certification. As part of the sustainable agriculture research program in the Economics Department at South Dakota State University (SDSU), we have been comparing 'organic' and 'conventional' crop prices over the past six years. This pamphlet contains an update of the price comparisons through 2000. …
Soybean Marketing Methods And Characteristics Of Arkansas Grain Handlers, Patricia A. Sauer, Nathan B. Smith, Andrew M. Mckenzie
Soybean Marketing Methods And Characteristics Of Arkansas Grain Handlers, Patricia A. Sauer, Nathan B. Smith, Andrew M. Mckenzie
Research Reports and Research Bulletins
Arkansas producers should acquaint themselves with all marketing methods available to them. Of particular importance is the pervasiveness of price risk within the current economic climate. This bulletin provides insights into the current structure of the grain marketing industry, soybean handler characteristics, and the availability and use of marketing alternatives in Arkansas. Arkansas soybean handlers were surveyed in 1998 to determine the marketing practices of both handlers and producers for the 1996 crop year. Particular emphasis was placed on the types of contracting methods offered by these handlers. Both facility size and corporate structure were found to play a significant …
