When should I consider replanting cotton?
Replanting is often a difficult decision.In fields with questionable stands, there are several things to consider before making a replant decision. 1) What is the calendar date? 2) What is the population of plants that will survive? 3) What is the health of those plants, especially their roots? 4) Are there large skips and frequent skips? 5) What is the productive capability of the soil, and is the field irrigated?
If plant distribution is fairly uniform in fields on productive soils, good yields can be made with low plant populations in the low 20,000 range, or as low as one per row-foot with no or few skips. If the stand is broken with numerous skips, replanting is in order at populations below 30,000 plants per acre, depending on the size and frequency of skips. Calendar date is significant. A stand you would plow up on May 1 would probably be kept on May 25.
If replanting is necessary, continue to use fungicides as appropriate. If the field has had heavy and/or frequent rains, or was flooded, additional preemergence herbicides will be needed. That decision needs to be made on a field-by-field basis. If replanting is done on the stale row, use a burn-down herbicide to kill the old stand and weeds which may have emerged on the row. This treatment could be mixed with the preemergence materials.
Here is a rule of thumb that seems to work better each year: "If you have enough cotton left to make the decision difficult, you probably have enough to keep."
STARKVILLE, Miss. -- When the calendar turns to September, many who call Mississippi home long for cooler temperatures to relieve the summer’s heat, but the state’s cotton growers want high temperatures and dry weather to drag into October.
STARKVILLE, Miss. -- MSU Extension agents will be assessing agricultural damage from early-June flooding until well into July, but preliminary estimates indicate losses could break records.
The 2019 Yazoo Backwater Area flood caused $617 million in crop damage alone. It looks like the more recent flood will exceed those losses.
Heavy rainfall, primarily north of U.S. Highway 82, throughout the second week of June waterlogged crops during critical growth stages. Flooding caused complete or partial losses in many fields.
Because it is the first crop planted starting in March, Mississippi corn is in much better shape than other row crops struggling with the challenges of wet, cool weather.
STARKVILLE, Miss. -- Mississippi row crop growers are planning to plant more soybeans and corn in 2021 than they did last year but not as much cotton, rice or hay.
The National Agricultural Statistics Service, a branch of the U.S. Department of Agriculture, publishes its planting intentions report each year at the end of March. This report provides a state-by-state estimation of how many acres of corn, soybeans, wheat and cotton farmers will plant in the upcoming growing season.
STARKVILLE, Miss. -- Each February marks the occasion for producers to share their research and programming needs with Mississippi State University agricultural specialists in person.
To comply with COVID-19 social distancing guidelines, the opportunity will be extended virtually this year.
