What should be the soil temperature at planting time?
Ideally, the seedbed should be at least 68º F at the two inch depth, with dry weather and at least 50 DD-60s expected in the next 5 days.
Planting into cold soils increases the likelihood of chilling injury to seedlings, weak and variable stands and replanting. Replanting is expensive, can complicate herbicide and insecticide programs and delay maturity.
Generally this will be the last week of April or the first week of May. Some years differ and common sense must apply.

STARKVILLE, Miss. -- Rain, cool weather, more rain and some wind have slowed cotton maturation, but since the crop was a little behind schedule, the damage may be less than if harvest were already underway.
Darrin Dodds, cotton specialist with the Mississippi State University Extension Service, said recent weather is causing some yield loss, but it is hard to estimate how much.
“Being late to a degree helped the crop because rain did not string out open cotton, but given that we are running out of heat, we may have been better off with an earlier crop that had been defoliated and was standing up when the rain came,” Dodds said.
STARKVILLE, Miss. -- Cotton will always have challenges, but few of them will ever compare to the boll weevils that thrived in Mississippi from 1904 until 2009.
“It is nearly impossible for this younger generation of consultants, scouts and growers to understand how hard boll weevils were to control and how much boll weevil control hurt beneficial insects and complicated cotton management,” said Will McCarty, who served as the Mississippi State University Extension Service cotton specialist during “the boll weevil wars.”
MACON, Miss. -- Farmers' independent natures make them strong, but when agricultural producers join forces, they can take success to the next level.
Darrin Dodds, cotton specialist with the Mississippi State University Extension Service, commended Mississippi farmers for their efforts to unite in the battle to eradicate boll weevils from the state.
“Historically, boll weevils were the prime pest in cotton fields. To control them, it took numerous pesticide applications,” he said. “Those treatments were costly and ate into the growers’ profit margins.”
STARKVILLE, Miss. -- Mississippi’s row crops have had enough rain, and most fields just need sunshine.
Erick Larson, grain crops specialist with the Mississippi State University Extension Service, said corn is mature and will gain no benefit from additional moisture. In the first couple of weeks of August, skies were overcast or rain was falling across most of the state.
STARKVILLE, Miss. -- Tropical Storm Cindy did not help the state's cotton crop that struggled with cool and wet weather all spring.
Darrin Dodds, cotton specialist with the Mississippi State University Extension Service, said in mid-June, cotton received about a week of the heat and sun it needs to thrive. Weather before that was not ideal, and rain remains in the forecast.
