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|
STARKVILLE, Miss. -- The Mississippi State University Extension Service will offer multiple opportunities March 3-5 for Delta row-crop producers to get help with an important irrigation planning tool.
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.
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.

John Monroe has been familiar with the Mississippi State University Extension Service since he was a child.
“I grew up on a small farm in George County,” says Monroe. “My dad took gardening seriously, and we weren’t blessed with the best soil. So my dad worked very closely with the county agent. He’d come out to our place on a regular basis.”
Before adopting RISER techniques on his farm, irrigating was the part of the growing season Clark Carter always dreaded.
“We would string out plastic pipe, punch holes in it every couple of feet, and hook it up, only to see it blow out when we turned the water on,” says the Rolling Fork row-crop producer. “Very seldom did you get a run of pipe to fill up and water a field. It was unorganized chaos every year.
