CLL15 is a new addition to the 2020 Horizon Ag rice seed lineup released by the University of Arkansas System Division of Agriculture and is highly anticipated by farmers to help maximize profitability. In university trials, CLL15 has rivaled CLXL745 yields across a wide geography over multiple years indicating an ability to produce not only high but also stable yields as well. CLL15 couples high yields with the ability to produce package quality rice, something that is much needed in the southern USA. CLL15 provides industry-leading blast tolerance and reaches harvest maturity within a couple of days of our earliest-maturing variety, CL111.

  • 0 Seed /lb is not an exact number; it is an average from multiple samples harvested over a wide geography.
  • 1 Seeding rate is a suggestion based on drill-seeding in ideal conditions and fungicide/insecticide treated seed. Planting non-treated seed is not recommended. Seeding rate should be increased by a minimum of 10 lbs/A when using non-treated seed, planting into a rough seedbed, water-seeding, high pH soils and soils with salinity issues.
  • 2 Nitrogen rate is a suggested rate based on a two-way split nitrogen application with the first application being applied on dry soil.
