Rice Leaf Blast Confirmed in Mississippi

Typical symptomology of rice leaf blast

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!” / Turnrow Talks

“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

Surge Valve Issues and Gleanings.

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!

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!

Will We Need to Irrigate Our Corn Again?

Irrigated Corn

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!

  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!

Identifying Corn Reproductive Growth Stages and Management Implications

Silk Stage

Corn reproductive stages generally comprise about 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions. . . . → Read More: Identifying Corn Reproductive Growth Stages and Management Implications

Programing a Surge Valve

Economic Benefits of Properly Managing Multiple Inlet Rice Irrigation

With water being one of the most expensive inputs of the rice producer, utilizing methods to limit the amount of water used makes economic sense.

Figure 1.

Adoption of multiple inlet irrigation has allowed producers to reduce water consumption. Water use with multiple inlet has translated into an 18% (fig.2) reduction in water cost over straight levee . . . → Read More: Economic Benefits of Properly Managing Multiple Inlet Rice Irrigation
