Description

The fate of nitrogen fertilizers in rice cultivars (Cica-8) is studied. Urea (1.973% at of 15N) and ammonium sulfate (1.826% at of 15N) are used. The fertilizers are applied in four levels (0,100,200 and 300 Kg N/ha) in shadow coditions and after 30 days of germination. (M.A.C.)

Abstract (Portuguese)

Estuda-se o destino dos fertilizantes nitrogenados quando aplicados a um cultivo de arroz (Cica-8). Utiliza-se urea (1,973% de atomos de 15N e sulfato de amonio (1,826% de atomo de 15N). Aplicam-se os fertilizantes em quatro niveis (0,100, 200 e 300 Kg N/ha), a sombra e apos 30 dias de germinacao. (M.A.C.)
