It is attacked by insects and diseases, such as Thrips tabaci Lindeman (Thysanoptera: Thripidae), Botrytis squamosa (J.C. Walker), Alternaria porri (Ellis) and Colletotrichum gloeosporioides f.sp. cepae Penz. This work evaluated the incidence of thrips, onion leaf blight, purple blotch, and smudge in eight elite populations of the Embrapa's onion breeding program ("CNPH 6415", "CNPH 6074", "CNPH 6244", "CNPH 6400 Chata", "CNPH 6400 Redonda", "Valencianita" x "Aurora", "Primavera" x "Pera Norte" and "Pera Norte" x "Primavera") and eight commercial onion varieties ("Granex 429", "BRS Cascata", "Belém IPA 9", "Crioula Alto Vale", "Bola Precoce", "Primavera", "Régia" and "1015 Y"). In regions of high incidence of C. gl...

The experimental design was completely randomized with 13 treatments and three replications. The treatments consisted of fertilization with missing element technique (with omission of liming and each one of the macro and micronutrients N, P, K, S, B, Cu, Fe and Zn). Dimorphandra mollis plant is tolerant to acid soil and responsive to the omission of phosphorus and potassium. The total flavonoids concentration was not influenced by the treatments.

Schott. The experiment was carried out in a greenhouse with 0-20 cm samples of a Oxisol under cerrado vegetation, collected at Montes Claros, Minas Gerais State, Brazil.
