2014 Preliminary Rice Variety Trial Data

StLeveeRice

Find below the Preliminary version of the 2014 Small Plot Official Rice Variety Trial. During 2014, small plot rice variety trials were conducted near the following locations; Choctaw, Clarksdale, Drew, Hollandale, Shaw, Stoneville, and Tunica. Variety trial data is presented segmented by technology,  conventional or Clearfield. As of current only rough rice yields are presented, milling . . . → Read More: 2014 Preliminary Rice Variety Trial Data

2014 Preliminary Side Inlet/Intermittent Irrigation Results

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

Keys to Diagnosing Common Nutrient Deficiencies in Rice

Potash Deficient Rice

Described below are the most common nutrient related issues that occur in Mississippi rice production and a few distinctive characteristics to key on when trying to properly identify each issue in the field.  Nutrient issues in rice can take on many appearances, but coupled with field histories some of the keys below will aid in identification.  . . . → Read More: Keys to Diagnosing Common Nutrient Deficiencies in Rice

Rice Stink Bugs in Mississippi Rice

As more and more of the rice crop starts to head, it is time to start thinking about rice stink bug. We have been sweeping some grass around the Delta for the last few weeks, and the one general comment I will make is that populations have been fairly low in most areas. We have seen fairly high numbers in a couple places, but it was small patches of heading grass in isolated locations. . . . → Read More: Rice Stink Bugs in Mississippi Rice

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’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!

Armyworms in Rice, Again!

It appears that 2014 is going to be the year of the armyworm in rice. I have had numerous calls, texts, and Tweets about armyworms in rice over the last week. If you have not had them in your rice to this point, consider yourself very lucky. . . . → Read More: Armyworms in Rice, Again!

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

Influence of Rainfall on Insecticide Efficacy

Every year at some point during the season we seem to hit a rainy spell where it seems to rain at some point every day and we have showers widely scattered across the state. It started raining last Wednesday and we have had some rain everyday since then and it is currently raining in Stoneville right now (Monday morning). With that, the questions start about how long you need to spray before a rain to get acceptable control. . . . → Read More: Influence of Rainfall on Insecticide Efficacy

Armyworms in Rice

Similar to most years when we have armyworms in wheat, there is the threat of having armyworms in seedling rice. We know of at least one rice field in Mississippi that was sprayed earlier this week. In general, damage from armyworms will not impact rice yields at this time of year unless they are beginning to reduce plant stand. This is especially true in hybrid rice planted at low seeding rates. . . . → Read More: Armyworms in Rice
