Resumo: The objective of this research was to evaluate the effect of fertilization with nitrogen, phosphorus andpotassium on thrips (Thrips tabaci) and downy mildew (Peronospora destructor), and on the yield of onion crop. The treatments were controls, half, one, two and four times the recommended amount of N, P2O5 e K2O. In the experiment with nitrogen the turkey manure was included to supply the recommended amount of nutrients. The onion thrips and downy mildew incidence were not influenced by the nutrients; only phosphorus had a positive linear tendency with the development of the insect. The yield increased mainly as a result of the use of phosphorus.

O objetivo do trabalho foi avaliar o efeito da adubação com nitrogênio, fósforo e potássio sobre a incidência de tripes (Thrips tabaci) e míldio (Peronospora destructor) e sobre produtividade da cultura da cebola.Os tratamentos foram metade, uma, duas e quatro vezes a dose recomendada para N, P2O5, K2O e testemunha sem adubação. No experimento com nitrogênio foi incluído esterco de peru para suprir o nutriente em dose recomendada. A infestação do inseto e os danos causados pelo patógeno não foram influenciados pelos nutrientes,exceto o fósforo, que apresentou correlação linear e positiva com a incidência de tripes. A produtividade foi incrementada pela aplicação de fósforo.
