Abstract: Dry land utilization for agriculture is often overlooked by policy makers who are more interested in increasing rice production in paddy fields. This is probably due to assumption that increasing rice production in paddy field is easier and more promising than upland rice field which has a higher risk of failure. In fact, dry land is widely available and potential to be developed for upland rice. The research was conducted on rain fed, located at Suka Makmur Village, District of Binjai, Langkat Regency. The material is 9 local gogo rice cultivars of exploration results from Province of Aceh and North Sumatra, Indonesia and one local rice varieties of Sumatra namely Sigambiri Merah. The parameters observed were plant height (cm), number of tillers (stem), number of productive tillers (stem), flowering age (day), harvest age (day), number of grains per panicle, yield per sample (g) and production per plot (kg). The results showed that there were significant differences between cultivars observed for some parameter namely plant height, number of productive tillers, flowering age, harvest age, number of grains per panicle, production per sample, production per plot, but the number of tillers show no significant difference.
