Arkansas Rice: Weather Allows Huge Leaps in Planting Progress

    Weather finally turned in our favor starting mid-week and planting progress actually occurred statewide for the first time all year.  While it’s only a few days, some were able to make huge leaps in planted acreage in that time.  Most will continue to press their luck on Saturday and hope scattered rains miss them to allow for additional planting on Sunday.

    That’s the first good news to report in a while.  Then more rain chances are forecast for the majority of next week, and that’s more bad news.  Another lost week of planting spells bad things for total rice acres in the state.  The game is far from over, and the price situation will encourage continued acres, but only time will tell how this plays out.

    Rice that has already emerged isn’t always looking that great right now.  Several straight years of cool, wet springs are making this the norm.  The upside of current and upcoming weather is warmer temperatures that will hopefully help straighten up the early rice.

    With everyone trying to get something planted this week, plenty for the first time, it’s a wild guess as to just how much overall progress is being made.  As of 4/25 we were 14% planted, and even if we jump to 30% planted we’ll still be behind 2019 and 2020.  Anything less than 33% on Monday’s report and we’ll still be on the slowest pace since 1993 (15%).

    What’s in a Rice Name?

    There definitely seems to be some confusion over naming conventions right now and what is what when it comes to rice.  Let’s do a quick review to be sure we all know what we’re working with this season and prevent any headaches.

    AgFax Weed Solutions


    Conventional varieties – Diamond, Jewel, Titan, Jupiter, Lynx, DG263L

    These varieties have NO herbicide tolerance traits.  The public varieties have seeding rates recommended in the range of 70-90 lb/acre.  DG263L is different and can be planted at these rates but may be seeded at 45-60 lb/acre.

    Clearfield varieties – CLL15, CLL16, CLL17, CLM04, CL111, CL151, CL153, CL163.

    The older varieties are more well-known (CL111, CL151, CL153, CL163) where CL stands for Clearfield and then the number of the release.  The newer varieties (CLL15, CLL16, CLL17, CLM04) have CL for Clearfield to start, then an L or M to designate Long-Grain or Medium-Grain, then the release number.  These varieties have seeding rates recommended in the range of 70-90 lb/acre.

    Provisia varieties – PVL02, PVL03

    Provisia has a PV to start then an L for Long-Grain, then the release number.  Tolerant only to Provisia herbicide.  Also note there no medium-grain cultivars tolerant to Provisia at this time.  These varieties have seeding rates recommended in the range of 70-90 lb/acre.

    Conventional hybrids – RT XP753, RT 7301, RT 7401, RT 7501

    These hybrids have NO herbicide tolerance traits.  These hybrids have seeding rates recommended in the range of 22-27 lb/acre.

    FullPage hybrids – RT 7321 FP, RT 7521 FP, RT 7421 FP

    These hybrids begin with a 7 to designate long-grain, the second number indicates maturity, the third number is herbicide tolerance (2=FullPage), and the fourth number is the release number.  The FP at the end is added confirmation that they’re FullPage.  Tolerant only to Preface and PostScript herbicides.  These hybrids have seeding rates recommended in the range of 22-27 lb/acre.

    MaxAce varieties – RTv7231 MA

    Similar to the previously mentioned RT naming convention, but notice the “v” in there to specify that it is a VARIETY, NOT a hybrid.  The third number is herbicide tolerance (3=MaxAce), and the fourth number is the release number.  The MA at the end is added confirmation that it’s MaxAce.  Tolerant only to Highcard herbicide.  This variety has a recommended seeding rate of 45 lb/acre.

    MaxAce hybrids – RT 7331 MA

    Similar to the previously mentioned RT naming convention.  This is a hybrid.  The third number is a 3 meaning MaxAce, and MA at the end is added confirmation.  Tolerant only to Highcard herbicide.  This hybrid has a recommended seeding rate of 22-27 lb/acre.
