For the week ending April 23, 2013, the USDA/NASS reported 4.3 days suitable for fieldwork. Topsoil moisture supplies were 2 percent short, 62 percent adequate, and 36 percent surplus. Subsoil moisture supplies were 1 percent very short, 7 percent short, 70 percent adequate and 22 percent surplus. Low temperatures ranged from 30 to 44 Continue reading Arkansas soybean update – April 26, 2013 As glyphosate-resistant weeds continue to be a major concern for soybean producers in Arkansas, many producers are relying on residual herbicides for control of problem weeds like Palmer amaranth. Metribuzin (Sencor/Lexone) is a PSII inhibitor (Group 5) herbicide that provides residual control of a number of annual grasses and broadleaf species. Metribuzin is especially Continue reading Metribuzin tolerance in soybean With the wet weather conditions we have been experiencing this spring, many soybean growers are concerned about the late start we have this year compared to the 2012 spring. Below is a study using historical data from the Soybean Research Verification Program (SRVP) to estimate optimum planting date to maximize soybean yield. Until recently, Continue reading Estimating yield potential of soybean by planting date Each year, numerous soybean varieties are commercially available to growers in Arkansas. However, only a limited number of soybean varieties have been tested in Arkansas at April plantings. Yield performance in early (April) plantings varies according to location, adaptability to soils, relative maturity, lodging, shattering potential, disease and nematode resistance, as well as herbicide Continue reading Need help selecting soybean varieties? 2012 Soybean Updates now available Due to the increase of glyphosate-resistance in the Midsouth, producers have a renewed interest in the use of metribuzin as a part of their soybean weed control program. Metribuzin is a PSII inhibitor (Group 5) herbicide that provides residual control of an assortment of annual grasses and broadleaf weeds in soybean, including Palmer amaranth. Continue reading 2012 Soybean variety metribuzin screening results now available The deadline for submitting harvest date for the Race for 100 & Go for the Green Yield Challenges is December 1, 2012. We have had 88 growers submit entry forms, but as of this week, only 14 producers have returned harvest data. Only one producer has returned harvest data for the Full Season Soybean Production Continue reading Deadline nearing for soybean yield challenge contests 
We are quickly approaching the end of the season on most of the fields in the verification program. We are still watching the later planted fields for insects and diseases. All the fields received rain from Isaac but only 1 suffered from the wind that accompanied the rain. We have had 2 of the fields harvested Continue reading Soybean Research Verification Program Update September 7, 2012 
Irrigation continues to be the main focus in the program, although we did catch a much needed rain on the fields in the River Valley and Central part of the State where we were limited on irrigation. Several of the fields in the program have either reached irrigation termination or are real close. Insect and Continue reading Soybean Research Verification Program Update August 17, 2012 Interested soybean producers have until tomorrow, Aug. 1, to submit the forms for the Race for 100 (bu/A) and Go for the Green ($$$$) Challenge. The information, instructions for submission and downloadable pdf forms for both contests can be accessed here. Thanks to the Arkansas Soybean Association, Arkansas Soybean Promotion Board, and University of Continue reading Attention soybean producers: Entry forms for soybean yield contests are due tomorrow! 
Rainfall during the week of July 10 gave some areas in the state a much needed break from irrigation, while some areas were not as lucky. Irrigation efforts have resumed keeping the crops moving forward. We had anticipated a large increase in bollworm numbers, but as of this date only one field in Cross Continue reading Soybean Research Verification Program Weekly Update – July 20,2012 |
