Onion Cultivar Selection for the Lowands of Central Province in Papua New Guinea.

Abstract

Selected bulb onion cultivars bred in Australia, New Zealand, Japan and the United states were evaluated for production potential under tropical lowland conditions in Papua New Guinea (PNG ) . Cultivars Rio Enrique, Tropic Brown , Dessex, Yellow Granex, Pira Ouro, Texas Early Grano and Rio Bravo have been identified and recommended for production in the area. Total marketable yield obtained from transplants ranged from 32. 1 to 43.6 t/ha . In the lowlands of Central Province, the most suitable planting time is from February to June. However, some cultivars may have potential for /ate-season planting in July and August.
