Summary : The growth and yield of corn varieties were better in Lospalos than Baucau, this was due to pronounced water limitation during 2009 dry season in Baucau. Application of N fertilizer at 30-60 kg N ha-1 did not improve the growth and yield of the corn plants due to water limitation in both sites. The N recovery efficiency of corn plants were not also affected by N fertilizer application, although Sele and Suwan 5 had relatively higher N recovery efficiency. On the other hand, the internal efficiency of N increased with increasing fertilizer N application (0-60 kg N ha-1) in 100% organic fertilizer application. This was also observed on Local variety and Sele in Baucau (severe water limitation), and on Suwan 5 in Lospalos (unstressed during early vegetative stage). Generally, Suwan 5 and the Local variety had better overall performance in Lospalos and in Baucau, respectively. Further evaluation is needed using varying sources of N fertilizer at 0-30 kg N ha-1 for possible improvement of yield and NUE of these genotypes during west season where water is not limiting in East Timor.
