|Abstract: ||A b s t r a c t : A field experiment wa s conducte d in three locations on the island of Santiago ( São Domingos , Serrado and Tarrafal) to estimate the influence of different doses of Nitrogen (O, 2 1 , 4 2 , 63 Kg N/ha) applied as
a m m o n i u m sulfate (NH^SO^) on the yield of t w o sweet potato varieties: 'fiegisto' (V2) and ' D j u d a m ' ( V I ) .
The experimental design was a randomized complete block with 4 replications. In São Domingos the treatments average yield of Resisto was almost three times as much the treatments average yield of Djudam and
in Serrado. The yield was aproximately twice as much for NO and N I and over three times as much for N2
and N3. On the other hand, Djudam produced relatively well in Tarrafal, being outperformed by Resisto only
with maximum N application. There was no significant difference in yield between the t w o varieties in Tarrafal
as indicated by the ANOVA test ( 9 5 % ) . However, both varieties responded positively to leveis of N in the same
