Abstract: The production of sorghum seed (Sorghum bicolor [L.] Moench.) faces the scarcity of land due to competition of land use with other food crops that have been cultivated for longer by farmers. Therefore, it were necessary to look for genotypes of sorghum that have the advantage to be planted intercropping with other crops and or able to produce seeds on ratoon crops. The aim of this research was to know the seed yield of various genotypes of sorghum harvested from monoculture, intercropping, and rattan planting systems.   Fifteen genotypes of sorghum were planted in three planting systems arranged factorially in a split plot design and repeated three times as blocks.  A split-plot  experiment was conducted during February 2016 – February 2017 at Village of Tulungagung, Sub District of Gadingrejo, Regency of Pringsewu, Lampung Province, Indonesia.  The experiment showed that planting systems did not affect on seed yield (weight of thousand grains seeds, seed weight per plant, and seed numbers per plant),  and affected significantly (P<0.01) on flowering day of 50% of plant.  There was an interaction effect significantly of planting systems and genotypes (P<0.05) on seed weight per plant and flowering day of 50% of plant.  Also, there was not any different of cassava yield harvested from intercropping with sorghum and from monoculture planting systems. Conclusion: There were several genotypes those yielding seed higher in monoculture or in ratoon, or in monoculture and ratoon, or in monoculture, intercropping, and ratoon systems and vice versa. The cassava yield did not differ between the inter-cropping of sorghum-cassava and the cassava monoculture systems.
