Resumo: | The objective of this work was to evaluate grain yield, oil content and nutrient content in leaf of sunflower plants with different dosis of N, P and K fertilization, with focus on biofuel production. A field experiment was conducted in an Ultisol on DDPA/SEAPI Research Center in Viamão, RS, Brazil. Treatments were three combined N, P and K dosis, based on recommended dosis to state of Rio Grande do Sul, using factors: level 0 (without the nutrient), level 1 (recommended dose) and level 2 (two times recommended dose). Six combinations of these dosis were tested: N0P0K0 (without fertilization), N1P1K1, N2P2K2, N2P1K1, N1P2K1 and N1P1K2. There was positive response of grain yield to fertilization, because all combinations of N, P and K dosis tested had higher yield than treatment without fertilization, with highest yield obtained whith recommended fertilization (N1P1K1), double of recommended fertilization (N2P2K2) and double of N dose (N2P1K1). Oil content in grains did not differ among the treatments, but treatments with fertilization had higher oil yield per hectare than treatment without fertilization, which was related to higher grain yield. Only with N there was increase of nutrient leaf content with fertilization, which occurred with the two applied dosis and was correlated with grain yield, indicating a potential of response to higher dosis than currently recommended. |

Foi realizado um experimento de campo em Argissolo Vermelho-Amarelo localizado no Centro de Pesquisa do DDPA/SEAPI em Viamão – RS. Os tratamentos consistiram de três doses de N, P e K combinadas, baseadas nas doses recomendadas para o Rio Grande do Sul, adotando-se fatores: nível 0 (sem o nutriente), nível 1 (dose recomendada) e nível 2 (duas vezes a dose recomendada). Foram testadas seis combinações destas doses: N0P0K0 (sem adubação), N1P1K1, N2P2K2, N2P1K1, N1P2K1 e N1P1K2. Observou-se resposta positiva do rendimento de grãos à adubação, pois todas as combinações de doses de N, P e K testadas apresentaram rendimento maior do que o tratamento sem adubação, com os maiores rendimentos sendo obtidos com a adubação recomendada (N1P1K1), o dobro da dose recomendada (N2P2K2) e o dobro da dose de N (N2P1K1). O teor de óleo nos grãos não diferiu entre os tratamentos, mas os tratamentos com adubação apresentaram maior rendimento de óleo por hectare do que o sem adubação, o que esteve relacionado com o maior rendimento de grãos. Somente no caso do N houve aumento no teor do nutriente na folha com a adubação, o que ocorreu nas duas doses de N aplicadas e apresentou correlação com o rendimento de grãos, indicando um potencial de resposta a doses mais altas do que as recomendadas atualmente.Departamento de Diagnóstico e Pesquisa Agropecuária.
