Resumo: The black oat (Avena strigosa Schreber) has been commonly used as green manure, in crop rotation systems under no-tillage, fall-winter crop, and for cattle grazing, hay, and silage. The objective of this work was to evaluate the nutrient concentrations in the flag leaf and grains of black-oat affect by phosphate and potassium fertilization. The experiment was carried out under field conditions on a Rhodic Nitosol, in Botucatu, São Paulo State, Brazil. Three doses of single superphosphate (0, 40 and 80 kg.ha-1 of P2O5) and three of potassium chloride (0, 20 and 40 kg ha-1 of K2O) were tested as a factorial (3 x 3), in a randomized complete block design, with four replicates. The fertilizers were applied in the sowing row. Ammonium sulphate was supplied for all plots (20 kg ha-1 of N applied at sowing and 30 kg.ha-1 after tillering stage). The concentrations of Ca, Mg, S, Fe, Mn, Cu and Zn in the flag leaf and the P and K concentrations in the grain were increased by phosphate fertilizer application. The potassic fertilization had no effect on the concentrations of nutrients in the flag leaf and grains of black-oat.

O objetivo deste trabalho foi avaliar os teores de macro e micronutrientes da folha bandeira e dos grãos de aveia-preta cv. Comum em função da adubação fosfatada e potássica. O experimento foi realizado em condições de campo, em Nitossolo Vermelho, em Botucatu-SP. Os tratamentos constaram de três doses de superfosfato simples (0, 40 e 80 kg ha-1 de P2O5) e três doses de cloreto de potássio (0, 20 e 40 kg ha-1 de K2O) dispostos em esquema fatorial (3 x 3), sob o delineamento de blocos casualizados, com quatro repetições. A adubação foi feita no sulco de semeadura. Em todas as parcelas foi aplicado sulfato de amônio, sendo 20 kg ha-1 de N na semeadura e 30 kg ha-1 em cobertura no final do perfilhamento. Os teores de Ca, Mg, S, Fe, Mn, Cu e Zn da folha bandeira e de P e K dos grãos foram influenciados pela adubação fosfatada. A adubação potássica não influenciou os teores de macro e micronutrientes da folha bandeira e dos grãos em aveia preta.UEL2009-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/407810.5433/1679-0359.2009v30n4p833Semina: Ciências Agrárias; Vol. 30 No. 4 (2009); 833-840Semina: Ciências Agrárias; v. 30 n. 4 (2009); 833-8401679-03591676-546Xreponame:Semina.
