Final Report for Selecting and Suppressing Triticale Cultivars for Organic No-till Rotations in Nebraska
Our objective was to improve the viability of organic bean production in wheat-based rotations by achieving triticale crimping success and a reasonably early planting date for soybeans and string beans in a rotational-till triticale mulch system. This objective was met by: 1) developing and employing an improved roller crimper design; 2) selecting among early-flowering high biomass experimental triticale lines in several organic environments to replace rye as a mulch crop; and 3) providing seed of triticale cultivars that function well as a mulch crop for further research on a larger scale.
Seed of NT15421, the best performing early flowering triticale line in 2016, was increased to 7000 pounds in Arizona and is available as untreated seed in cold storage for farm-scale mulch crop experiments. A ton of this triticale seed was planted at Allison Farm of Western Illinois University in September 2018 to continue their research on using triticale as a mulch crop for soybean production.
