| dc.description | The sunflower is presented as a promising crop for biodiesel production, in addition, to provideimproved soil fertility by having a high capacity for nutrient cycling absorbed in depth and a reducedrate of nutrient export, but it is very demanding on nutrients as boron and potassium. Therefore,we evaluated the effect of fertilization borácica and potassium in sunflower farming Catissol. Theexperimental design was a randomized complete block in a split-plot, 5 x 4 with five repetitions. Thetreatments consisted of a combination of five doses of boron (0, 2, 4, 6 and 8 kg ha-1), with four levelsof potassium (0, 30, 60 and 90 kg ha-1). Plants were harvested at 72 days after sowing and wereevaluated for height, leaf area, dry biomass and productivity. Doses of 6 and 90 kg ha-1 of boron andpotassium, respectively, provided better responses in height (190 cm), leaf area (4374 cm2), shootdry biomass (175 g) and productivity of 4170 kg ha-1. | en-US |
| dc.description | O girassol apresenta-se como uma cultura melhoradora da fertilidade do solo por apresentar uma elevada capacidade de ciclagem de nutrientes absorvidos em profundidade e uma reduzida taxa de exportação de nutrientes. Mas, é bastante exigente em nutrientes com potássio e boro. Diante disso, avaliou-se o efeito da adubação borácica e potássica no girassol cultivar Catissol. O delineamento utilizado foi em blocos casualizados em esquema de parcelas subdivididas, 5 x 4 com cinco repetições. Os tratamentos foram constituídos da combinação de cinco doses de boro (0, 2, 4, 6 e 8 kg ha-1), com quatro níveis de nitrogênio (0, 30, 60 e 90 kg de K ha-1). As plantas foram coletadas aos 72 dias após a semeadura e foram avaliadas quanto à altura, área foliar, massa seca e produtividade. A dose 6 kg ha-1 e 90 kg ha-1 proporcionaram melhores respostas paras as variáveis estudadas.
