Corn and Grain Sorghum Update – Dr Jason Kelley (Wheat and Feed Grains Specialist)
Rains on April 9th were either a blessing or a curse, depending on where you are located. Rainfall amounts were variable across the state, but 0.5 to 2.0 inches appear to be typical. Many producers in the south half of the state are done planting corn and the rain was needed to get residual herbicides activated. I noticed yesterday I had weeds emerging in corn planted on March 31, even though atrazine and dual were applied immediately after planting, but the field had not received adequate rainfall since planting to activate herbicides. Parts of Northeast Arkansas were still wet prior to the rain on April 9th and corn planting has been limited in those areas by wet fields. Warm temperatures with highs in the 80’s really accelerated corn emergence this week. Most fields are emerging within 7-9 days after planting.
Grain sorghum planting like corn has progressed rapidly over the past week in southern and central portions of the state, while planting been delayed in parts of Northeast Arkansas.
Corn and Grain Sorghum Research Verification – Kevin Lawson (Corn & GS Verification Coordinator)
Research verification fields continue to be planted between rains. Clay County remains one of the wettest areas of the state and limited field work has been done there. Pope County is waiting on this round of rain and will try to get planted next week. I hope to plant grain sorghum fields next week.
Southeast Arkansas Update – Wes Kirkpatrick (Desha County)
Corn planting is wrapping up. There have been several acres of grain sorghum planted. Forecasted rain may prove beneficial in some areas, as they are getting somewhat dry.
Central Arkansas Update – Anthony Whittington (Jefferson County)
Planting is in full swing in Jefferson County. About 40% of corn crop has been planted. We have a lot of farms planting grain sorghum that haven’t planted that crop in sometime.
Northeast Arkansas Update – Stewart Runsick (Clay County)
More rainfall has been received across the area with more predicted. Fields are saturated and little to no field work has been completed. There has been increased interest in grain sorghum with talk of as much as 10,000 acres up from 2,000 acres last year. There has been a scramble to find seed. Corn acres are likely to decrease the later we get. The forecast calls for rain all next week. Surly we will miss one soon.
River Valley Update – Kevin VanPelt (Conway County)
Again this week, field conditions were good the first few days and producers in the River Valley were able to stay in the fields getting corn planted. Some of the Standardized County Hybrid Trials were also planted this week, but with storms moving in last night (April 8) and next week’s forecast, it looks like producers may be waiting again to get back in the fields for a while.
Temperatures and heat unit accumulation continues to be higher than the 30 year average. Even with the cooler weekend, warm temperatures during the week more than made up for the lower weekend heat units. V2 (two leaf) is the next growth stage to be looking for. In the Corn Research Verification Program, it takes around 255 heat units to get to V2 from planting.
