Performance of Nine Onion Cultivars in Southern Puerto Rico

Abstract

Nine onion cultivars were evaluated for yield and total solids content. Hybrid onion Granex 33 was the highest yielder with 36,476 kg/ha and 7.6% total solids, while Red Creole was the lowest yielder with only 16,302 kg/ha, and an excellent total solids content of 14%. Texas Grano 502, our highest yielder in previous experiments, ranked second with 33,895 kg/ha and an acceptable total solids percentage of 7.8.
