We’ve talked a lot in recent weeks about the advantages of planting proven Clearfield® and Provisia® varieties, varieties that farmers have had the chance to see perform on their own farms, in agronomic situations similar to theirs and yield results from multi-year university testing that has to be done before a Horizon Ag variety ever makes it to the commercial stage. At Horizon Ag, we stand behind our elite varieties like CLL16, CLL17 and PVL03, as well the entire Horizon Ag portfolio. And we’re happy to talk to you in person anytime about that performance and what it means for your farm.
In fields from the Missouri Bootheel to rice fields west of Houston, Texas,CLL16has consistently shown it can yield with or better than top-performing varietals and even hybrids. This is a varietyyielding 200-plus bushels per acre consistently across a wide range of geographieswhile offering the advantages of a Clearfield variety at a lower seed cost than hybrids. CLL16 yielded a two-year mean of 210 bushels per acre in the 2020-21 Arkansas Rice Performance Trials.
Other benefits are its resistance to blast, strong performance in both flood and row rice situations and its great milling quality — all of which have contributed to CLL16’s reputation as “The Complete Package.”
CLL17performed very well in its first commercial season in 2021, with both the main crop and ratoon crop. Combine that performance with its higher nitrogen utilization efficiency and excellent genetic resistance to blast and Cercospora, and CLL17 should be a great fit for Coastal Region rice fields in 2022.
In three years of university testing, CLL17 averaged 6% higher yields than CL153. And in 59 trials throughout the Mid-South Rice Belt beginning in 2015, the variety averaged 7,841 pounds per acre for the main crop, compared to 7,155 pounds for CL111, 7,330 pounds for CL153 and 6,653 pounds for Cheniere, according to LSU AgCenter data.
The average yield advantage was 7% over CL153 across 20 tests in 2019 in Louisiana, Arkansas and Texas.
In seed production fields in South Louisiana and Texas the following year, CLL17 averaged 50-plus barrels per acre, and in our foundation field at the rice station, it yielded 59 barrels per acre, which was higher than any other variety ever increased.
Milling yields for CLL17 averaged roughly 60/70 across 41 trials, compared to 63/71 for CL111, 62/71 for CL153 and 63/72 for Cheniere.
New PVL03, the latest Horizon Ag Provisia variety, has proven yield potential rivaling and even exceeding that of many other top-performing rice lines. Louisiana trials in 2019 and 2020 showed PVL03 yielding almost 8,500 pounds per acre, out yielding Cheniere and putting it on par with high-yielding Clearfield varieties like CL153.
In the 2021 Arkansas Rice Commercial Trials across 11 locations in the state, PVL03 averaged 185 bushels per acre, with an average milling yield of 58–71, according to preliminary results. PVL03 has a much-improved disease package compared to its predecessors, thanks to Pi-ta and Pi-ks blast-resistance genes. It also has a gene for Cercospora resistance.
All of these benefits come with the advantages of the Provisia Rice System and Provisia herbicide. The Provisia Rice System has already proven to be one of the most effective weed management tools available for Southern rice. Provisia herbicide doesn’t require a safener, so it’s going to be more effective overall. Best of all, farmers have seen Provisia work and are using it to completely turn around thousands of acres lost to weedy hybrid rice and resistance issues.
