As we approach the end of August, terminating cotton irrigation is on the mind of many folks. In cotton, we recommend terminating furrow irrigation at first cracked boll. If you anticipate bolls opening in the immediate future and have been dry for some time, a final irrigation event may be in order. However, once bolls begin . . . → Read More: Cotton Irrigation Termination
This week I thought I would share with you the progress of our rice irrigation studies. This summer we have three producer “on farm” irrigation trials. Each producer agreed to irrigate his field conventionally through levee gates, via side inlet, and an additional side inlet utilizing intermittent flood. The producer originated irrigation on the conventional and . . . → Read More: 2014 Preliminary Side Inlet/Intermittent Irrigation Results
This week we encountered another issue with a surge valve. After irrigating with a surge valve the producer noted that neither the 6” nor 12” sensors responded to the irrigation. When investigating the problem it appeared that the grower had done as instructed, making the proper adjustments to the advance cycle. What’s going on? Further investigation . . . → Read More: Another Surge Valve Experience!

Typical symptomology of rice leaf blast
Last week’s weather pattern in the Delta provided near perfect conditions for rice blast (Pyricularia grisea) to occur. Rice blast is generally categorized by the plant part infected (e.g., leaf, neck, panicle). Blast favors mild humid weather, frequent rainfall, and extended periods of leaf wetness. On susceptible cultivars, yield loss . . . → Read More: Rice Leaf Blast Confirmed in Mississippi
“It ain’t over till it’s over!” Amazing as it seems, several producers have not laid poly pipe. After the five plus inches of rainfall we received last week, some producers are questioning the need to lay pipe this late in the season. With harvest for corn and rice within 30 days, does it make sense to . . . → Read More: “It ain’t over till it’s over!” / Turnrow Talks
This past week we encountered the following situation. A Grower irrigated a silt loam field utilizing a surge valve. When he checked his moisture probes neither the 6” nor the 12” Watermark™ sensor had moved. What’s going on? After careful evaluation we realized that the grower had prematurely terminated the irrigation cycle.
A few weeks ago we . . . → Read More: Surge Valve Issues and Gleanings.
It’s okay to let it down!
Defining proper flooding of rice can be somewhat challenging depending who you talk to. One thing is for sure, to take advantage of the cost saving of straight levees and multiple inlet rice production, the depth of flood has to be managed. With the days of cheap water behind us and . . . → Read More: It’s okay to let it down!
Considering the abundant rainfall during June and the corn crop progressing closer toward maturity, many are wondering whether additional irrigation may even be needed. This article discusses how to make that and other late-season irrigation decisions. . . . → Read More: Will We Need to Irrigate Our Corn Again?
Now is the time to prepare for 2015 PHAUCET implementation!
Without a doubt the installation of PHAUCET (Pipe Hole and Universal Crown Evaluation Tool) on every acre of your farm is the most important water saving strategy you can implement. PHAUCET allows you to irrigate your fields uniformly with each furrow watering out at . . . → Read More: Now is the time to prepare for 2015 PHAUCET implementation!
