UFSMFW 2202 - Early black oat cultivar for ground cover

Authorship SCIMAGO INSTITUTIONS RANKINGS

UFSMFW 2202 is an early black oat cultivar with high dry matter and grain yield potential. When used in rotation systems, the early cycle has the immediate advantage of allowing anticipated sowing of subsequent crop. Initially, the cultivar is recommended for the North and Northwest of Rio Grande do Sul.
