Title A name given to the resource Incidência do míldio em cebola sob adubação mineral e orgânica Incidence of downy mildew in onion growing under mineral and organic fertilization Creator An entity primarily responsible for making the resource Paulo Antônio de S. Gonçalves, Carlos Roberto Sousa e Silva, Pedro Boff Description An account of the resource Analisou-se a relação entre adubação mineral e orgânica sobre a incidência de míldio (Peronospora destructor) em cebola (Allium cepa). O trabalho constituiu-se de dois experimentos localizados em Ituporanga, conduzidos entre agosto e dezembro de 1998. O experimento 1, com fontes orgânicas, constou dos tratamentos: esterco de suínos, esterco de aves, composto, esterco de peru e húmus, na dosagem de 75 kg/ha de N; esterco de suínos, na dosagem de 37,5 kg/ha de N; adubação mineral, 30-120-60 kg/ha de N-P2O5-K2O; 60-240-120 kg/ha de N-P2O5-K2O e testemunha sem adubação. O experimento 2 constou dos tratamentos: fontes minerais, 30-120-60 kg/ha de N-P2O5-K2O; 90-360-180 kg/ha de N-P2O5-K2O; 75 kg/ha de N; 225 kg/ha de N; 80 kg/ha de P2O5; 240 kg/ha de P2O5; 60 kg/ha de K2O; 180 kg/ha de K2O; esterco de suínos + fosfato natural, em três combinações, 7,9+0,1, 15,7+0,2 e 47,2+0,6 t/ha, respectivamente; testemunha sem adubação. Não houve diferença entre as fontes mineral e orgânica sobre a incidência de míldio. A relação entre nutrientes e doença foi variável entre datas de amostragem e distinta para fontes minerais e orgânicas.The incidence of downy mildew, Peronospora destructor Berk. Casp., in onion growing in chemical and organic fertilized plots was evaluated in Ituporanga, Santa Catarina State, Brazil. Two experiments were carried out between August to December 1998. The treatments in the first experiment with organic sources were: 75.0 kg/ha of N (swine manure; poultry manure; compost; turkey manure; humus); 37.5 kg/ha of N (swine manure half dose); control (NPK, 30-120-60 kg/ha of N-P2O5-K2O) and double rate of NPK (60-240-120 kg/ha of N-P2O5-K2O); and unfertilized control. In mineral fertilization experiment, the mineral levels were 1 and 3 times the recommended rates based on soil analysis: 30-120-60 kg/ha of N-P2O5-k2O; 90-360-180 kg/ha of N-P2O5-K2O; 75.0 kg/ha of N; 225.0 kg/ha of N; 80.0 kg/ha of P2O5; 240.0 kg/ha of P2O5; 60.0 kg/ha of K(2)0; 180.0 kg/ha of K(2)0. Control plots with organic fertilization received swine manure + phosphate rock in three treatments (75.0 kg/ha of N + 80.0 kg/ha of P2O5; 225.0 kg/ha of N + 240.0 kg/ha of P2O5; 37.5 kg/ha of N + 40.0 kg/ha of P2O5) and unfertilized check. Downy mildew incidence was similar between treatments with fertilizer and no fertilizer check. Mineral fertilization did not increase downy mildew incidence compared to the organic treatments. The relationship between nutrient and disease varied according to sampling date and differed for mineral and organic sources.
