Arkansas Cotton Variety Test 2016, Fred Bourland, W. Barnett, C. Kennedy, L. Martin, A. Rouse, B. Robertson

Arkansas Agricultural Experiment Station Research Series

The primary goal of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas.

Arkansas Soybean Research Studies 2015, Jeremy Ross

Arkansas Agricultural Experiment Station Research Series

Arkansas is the leading soybean-producing state in the mid-southern United States. Arkansas ranked 10th in soybean production in 2015 when compared to the other soybean-producing states in the U.S. The state represents 4.0% of the total U.S. soybean production and 3.7% of the total acres planted to soybean in 2015. The 2015 state soybean average was 49 bushels per acres, 0.5 bushel per acres less than the state record soybean yield set in 2014 (Table 1). The top five soybean-producing counties in 2015 were Mississippi, Desha, Poinsett, Phillips, and Arkansas Counties. These five counties accounted for 35% of soybean production …

Corn Residue Use By Livestock In The United States, Marty R. Schmer, Rachael M. Brown, Virginia L. Jin, Robert B. Mitchell, Daren D. Redfearn

Department of Agronomy and Horticulture: Faculty Publications

Corn (Zea mays L.) residue grazing or harvest provides a simple and economical practice to integrate crops and livestock, but limited information is available on how widespread corn residue utilization is practiced by US producers. In 2010, the USDA Economic Research Service surveyed producers from 19 states on corn grain and residue management practices. Total corn residue grazed or harvested was 4.87 million ha. Approximately 4.06 million ha was grazed by 11.7 million livestock (primarily cattle) in 2010. The majority of grazed corn residue occurred in Nebraska (1.91 million ha), Iowa (385,000 ha), South Dakota (361,000 ha), and Kansas …

A Comprehensive Image-Based Phenomic Analysis Reveals The Complex Genetic Architecture Of Shoot Growth Dynamics In Rice (Oryza Sativa), Malachy T. Campbell, Qian Du, Kan Liu, Chris J. Brien, Bettina Berger, Chi Zhang, Harkamal Walia

Agronomy & Horticulture -- Faculty Publications

Early vigor is an important trait for many rice (Oryza sativa L.)- growing environments. However, genetic characterization and improvement for early vigor is hindered by the temporal nature of the trait and strong genotype × environment effects. We explored the genetic architecture of shoot growth dynamics during the early and active tillering stages by applying a functional modeling and genomewide association (GWAS) mapping approach on a diversity panel of ~360 rice accessions. Multiple loci with small effects on shoot growth trajectory were identified, indicating a complex polygenic architecture. Natural variation for shoot growth dynamics was assessed in a subset …

Integrating Kaolin Clay For Ambrosia Beetle Management In Ornamental Crops Of Eastern Redbud, Christopher T. Werle, Karla M. Addesso, Blair J. Sampson, Jason B. Oliver, John J. Adamczyk

Agricultural and Environmental Sciences Faculty Research

Invasive ambrosia beetles (Coleoptera: Curculionidae) are an important pest problem at ornamental tree nurseries. Available chemical treatments are not completely effective and, due to the length of the beetle dispersal period and insecticide breakdown, repeated treatments can become costly in terms of application expense and nontarget impacts. Additional options are needed to reduce application frequency and to provide an acceptable level of crop protection. Four treatments were tested using ethanol-injected eastern redbud trees at research sites in Mississippi (MS) and Tennessee (TN) over 2 years (2014–15), with the number of new ambrosia beetle galleries compared over time on 1) nontreated …

Potassium Applications And Yellow Shoulder Disorder Of Tomatoes In High Tunnels, Elizabeth Maynard, Israel S. Calsoya, Jill Malecki

Purdue Fruit and Vegetable Research Reports

Tomatoes grown in unheated high tunnels can suffer significant loss in quality due to yellow shoulder disorder, particularly in susceptible varieties. This paper reports on a preliminary trial to determine whether incidence and severity of the disorder could be influenced by applying potassium fertilizers. Plots with higher leaf potassium content tended to have less fruit with severe yellow shoulder disorder, but increasing the amount of potassium fertilizer applied did not significantly reduce the disorder. From this study it isn’t possible to make specific recommendations for reducing yellow shoulder disorder with potassium applications.

Muskmelon Variety Trial In Southwest Indiana — 2016, Wenjing Guan, Dennis Nowaskie

Purdue Fruit and Vegetable Research Reports

This is a compilation of 21 research trial reports from four land-grant universities in the Midwestern United States. Crops include cantaloupe, pickling cucumber, pepper, potato, pumpkin, summer squash and zucchini, sweet corn, tomato, and watermelon. Somecrops were evaluated in high tunnels or hoophouses. Most trials evaluated different cultivars or varieties. One report addressed plant spacing for sweet corn and one addressed soil block for production of tomato seedlings. A list of vegetable seed sources and a list of other online sources of vegetable trial reports are also included.

Midwest Vegetable Trial Report For 2016, Elizabeth Maynard, Brad Bergefurd

Purdue Fruit and Vegetable Research Reports

This is a compilation of 21 research trial reports from six land-grant universities in the midwestern United States. Crops include dry beans, cantaloupe, cucumber, pepper, pumpkin, sweet corn, summer squash, winter squash, strawberry, tomato, watermelon, and winter melon. Several crops were evaluated in high tunnels or hoop houses. Most trials evaluated different cultivars or varieties. Three reports addressed specific growing practices: the use of poly-coated urea to supply nitrogen to sweet corn, potassium fertilization for high tunnel tomatoes, and use of cereal rye cover crop in butternut squash.

Editorial: Genomic Approaches For Improvement Of Understudied Grasses, Keenan Amundsen, Gautam Sarath, Teresa Donze-Reiner

Department of Agronomy and Horticulture: Faculty Publications

Grasses are diverse, spanning native prairies to high-yielding grain cropping systems. They are valued for their beauty and useful for soil stabilization, pollution mitigation, biofuel production, nutritional value, and forage quality; grasses encompass the most important grain crops in the world. There are thousands of distinct grass species and many have promiscuous hybridization patterns, blurring species boundaries. Resources for advancing the science and knowledgebase of individual grass species or their unique characteristics varies, often proportional to their perceived value to society. For many grasses, limited genetic information hinders research progress. Presented in this research topic is a brief snapshot of …
