The objectives of the study was to determine the effect of cutting height of main crop on the yield of rice ratoon, and to select genotypes with high productivity on tidal swamp land. The method used was a factorial randomized block design with three replications. The first factor was cutting height of 10 cm, 20 cm and 30 cm from soil surface. The second factor was five genotypes selected from previous study, namely Cimelati, Hipa-5, Rokan, IPB106-7-47-DJ-1 and IPB106-F-8-1. The results showed that combination of genotypes and cutting height affected ratoon yield. Cutting height of 20 cm increased the number of filled grain in almost all genotypes, increased growth rate of ratoon to 1.5 cm day-1 and increased growth uniformity of ratoon of Cimelati, Hipa-5 and Rokan geontypes, with production 3.0 ton ha-1, 2.8 ton ha-1 and 2.2 ton ha-1, equal with 57.2%, 60.1%, 52.7%, of the main crop respectively. Cutting height of 10 cm above soil surface showed the best results for IPB106-7-47-DJ-1 and IPB106-F-8-1 genotypes, with the highest yield of ratoon 2.1 ton ha-1 and 1.5 ton ha-1, equal with 45.8% and 35.4% of the main crop respectively. Keywords: cutting height, ratoon, yield
