New CLL19, developed in the LSU AgCenter rice breeding program, has very good milling yields, blast resistance and lodging tolerance. It has demonstrated excellent yield potential over the last four years of multi-location testing and has consistently been the top-yielding semi-dwarf Clearfield variety across trials. CLL19 is earlier than most Clearfield varieties and is shorter-statured, with good stem strength. It also has excellent ratoon crop potential.

    • 1 Seed/lb is not an exact number; it is an average from multiple samples harvested over a wide geography.
    • 2 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.
    • 3 Nitrogen rate is a suggested rate based on a two-way split nitrogen application with the first application being applied on dry soil.
