Yield and Total Solids Content of Four Onion, Allium cepa, Cultivars in Southern Puerto Rico

Abstract

The yield and total solids content of four onion cultivars were evaluated in a San Anton soil (Cumulic Haplustolls, fine-loamy, mixed, isohyperthermic) on the southern irrigated coastal plain of Puerto Rico. There was no significant difference in yield between Texas Grano 502 (26,953 kg/ha) and Hybrid F₁ Granex 33 (27,686 kg/ha). Both significantly outyielded cultivars Dehydrator #4 (13,432 kg/ha) and White Creole (12, 135 kg/ha). White Creole was significantly superior in total solids content to Dehydrator #4, Hybrid F₁ Granex 33 and Texas Grano 502. Bulbs of Texas Grano 502 and Hybrid F₁ Granex 33 were significantly superior in mean weight to those of White Creole and Dehydrator #4.
