How much yield benefit do we get from irrigation in Mississippi?
Any yield response depends on the management and timeliness of the irrigation. The following table displays accepted yield data for the major irrigated crops in Mississippi.
Accepted Yield Responses By Crop
|Cotton||180 pounds of lint|
|Corn||50 to 180 (Average MS Yield is 90 bushels.)|
|Grain Sorghum||No good data.|
How much water does it take for different irrigation systems?
Furrow--A minimum of 10 GPM per acre.
Flood--(Rice), 15-20 GPM per acre.
Border--A minimum of 10 GPM per acre.
Center Pivots--A minumum of 4.5 GPM per acre to put out a gross of 1 inch in 4 days.
(Many producers are upsizing to put out an inch in 3 days or 6.25 GPM per acre).
Towable Privots and Traveling Guns--A minumum of 5 GPM per acre total to by irrigated.

How many acres of Mississippi crops are irrigated?
(This will vary from year to year)
|Other Crops||100,000 acres|
When do you start to irrigate?
When you feel like an inch of rain would do some good and when soil moisture in the root profile reaches 50 percent depletion.
The critical stages for the different crops are:
|Corn||Eight leaf stage and very critical at tassel and silk|
|Grain Sorghum||Boot stage|
STONEVILLE, Miss. -- Mississippi State University agricultural leaders looked far and wide to find a new specialist to guide farmers with irrigation concerns.
Drew Gholson started April 1 as an assistant professor and the irrigation specialist with the MSU Delta Research and Extension Center and the Mississippi River Valley Alluvial Aquifer Water Center. He replaces Jason Krutz, who was promoted to lead the Mississippi Water Resources Research Institute.
Rivers have been the lifeblood of communities since ancient civilizations began. Healthy river systems are just as critical to modern communities as they were to settlers who navigated the rolling waters to explore America.
PINEY WOODS, Miss. -- Mississippi producers will receive training on irrigation practices during an April 20 field day.
The Alliance of Sustainable Farms will hold its Drip Irrigation and Plastic Mulch Laying field day on the National Center for Appropriate Technology demonstration farm at the Piney Woods School. The workshop will provide information on ecologically sound and profitable production practices.
Along with drip irrigation and plastic mulch laying, the workshop will also include transplanting demonstrations.
RAYMOND, Miss. -- Agricultural professionals, educators and service providers are invited to attend a training session on irrigation, water management and related technologies.
Two identical sessions will be offered. The first is March 6 at the Small Farm Training Center in Carriere. The second is March 7 at Jumpertown High School in Booneville.
Topics include production of specialty crops on small farms and application of federally funded cost-share programs and technical assistance for small farms.
STONEVILLE, Miss. -- Alternating wet and dry production is a radical new way to grow rice, and some Mississippi producers are finding the idea not only seems feasible in theory, but also works well in practice.
Jason Krutz is an irrigation specialist with the Mississippi State University Extension Service and a researcher with the Mississippi Agricultural and Forestry Experiment Station. He said the technique, known as AWD, grows rice without standing water, which reduces water use by about a third while also maintaining yields.
In this "What's New in Extension," Extension agents implement better safety standards, train to deliver Mental Health First Aid, and receive national recognition. Also, new irrigation and specialists join the Extension family.
