7 ARKANSAS SOYBEAN PERFORMANCE TESTS R.D. Bond 2, D.G. Dombek 3, and J.A. Still 4 INTRODUCTION Soybean variety and strain performance tests are conducted each year in Arkansas by the University of Arkansas System Division of Agriculture Arkansas Crop Variety Improvement Program. The tests provide information to companies developing varieties and/or marketing seed within the State, and aid the Arkansas Cooperative Extension Service in formulating variety recommendations for soybean producers. METHODS Varieties and strains containing any herbicide tolerance trait(s) were eligible for entry into two types of tests: Early Planted Tests (EPTs) and Full-Season Tests (FSTs). Entries in the FSTs were also tested in a simulated Double-Crop test. To facilitate field operations and to allow for fairer comparisons between varieties and strains in both types of tests, entries were divided into maturity classes based on information provided by the originating company or institution. Entries in the EPTs were divided into four maturity classes. Entries in the FSTs were divided into five maturity classes. Entries in the Early, Mid, and Late Group IV EPTs and FSTs had relative maturities ranging from 4.0 to 4.5, 4.6 to 4.7, and 4.8 to 4.9, respectively. Entries in the Group V EPTs had relative maturities ranging from 5.0 to 5.3. Entries in the Early and Late MG V FSTs had relative maturities ranging from 5.0 to 5.3 and 5.4 to 5.9, respectively. The 2014 soybean performace tests contained 118 EPT entries and 253 FST entries. The 2014 soybean FSTs were conducted at the Northeast Research and Extension Center (NEREC) at Keiser, the Lon Mann Cotton Research Station (LMCRS) near Marianna, the Rice Research and Extension Center (RREC) near Stuttgart, the Rohwer Research Station (RRS) near Rohwer and the Vegetable Research Station (VRS) near Kibler. The EPTs were established at the NEREC, the RRS, the LMCRS, and at the Berger Farm, near Weiner, Ark. A test location map can be found inside the back cover. Within each test, entries were arranged as a randomized complete block design with three or four replications. Plots in all tests were 4 or 5 rows wide depending on between-row spacing and feet in length. Seeds were packaged for recommended planting rates and were planted with a cone planter. Specific location and cultural practice information accompany each table. All rows of each plot were harvested for yield determination, except in the NEREC and Non- tests, all RREC tests, and all VRS tests where only the interior rows were harvested. Percent moisture was recorded for all harvested seed and plot weights were adjusted to 13% moisture. Plot weights of all tests were converted to yield in bushels per acre (bu/a). Plots were visually rated for shattering and lodging. ing ratings were carried out on border rows according to the following scale: 1. No shattering % shattered % shattered 5. 20% or more shattered % shattered Lodging ratings were recorded on a scale from 1 to 5 based on the following criteria: 1. Almost all plants erect 2. Either all plants leaning slightly, or a few plants down 3. Either all plants leaning moderately, or 25-50% of the plants down 4. Either all plants leaning considerably, or 50-80% of the plants down 5. All plants down badly plant height was recorded in inches for each plot in the first replication of each test.
