In the Gash Delta the traditional farmer method of very wide plant spacing is unappropriate under average or good flood irrigation level. Different intra-row spacings of 30, 50 and 70 cms along 80 cm row spacing were compared with the farmers practice (80-100x80 cm). The local tall and late cultivar (Aklamoi) and the improved cultivar Gadam El Hamam were used in the experiment in a randomized complete blocks design with four replications. Across two seasons the highest mean grain yield was recorded at the spacing 50x80 cm. The short and earlier variety Gadam El Hamam tended to give its highest yield at 30x80 cm, while the tall and late Aklamoi gave the best yield at 50x80 cm. Plant height and head length were not affected by plant spacing. It was recommended that the short, early maturing sorghum Gadam El Hamam to be planted at the spacing of 30-50x80 cm, while Aklamoi to be planted at 50x80 cm using ridger plough under good flood irrigation levels in the Gash Delta
