dc.description	The influence of K2O (0, 40, 80, 120 kg/ha-1) at varying rates of N application (0, 30, 60 kg/ha-1) at planting, on panicle blast (Pyricularia grisea (Cooke) Sacc.) was studied in a field experiment conducted during three consecutive years with the upland rice cultivar Douradao. Panicle blast severity decresed with increasing rates of potassium in the absence of nitrogen (N0). The relationship between panicle blast and K rats was quadratic at 30 kg ha-1 of nitrogen. Significant response to K fertilization was not obtained at 60 kg ha-1 of nitrogen in relation to panicle blast severity.
