Guar was introduced in the Gash Delta for evaluation under the flood irrigation system as a new cash crop and/or fodder legume, but non-competitive with the main crops. As a drought tolerant crop, it was suggested to be planted in poorly-flooded areas or in the peripheries of the basins (misgas). The only variety available Texcel was planted in an intrarow spacing experiment for three seasons. Seed yield of guar was evaluated from broadcasting along 80 cm furrows or from 20 and 40 cm intra-row spacings. Differences in seed yields were not significant. The spacing 20x80 cm produced the highest seed yield of 1806 kg/ha, which was only 4% more than broadcasting. Although the widely spaced plants at 40 cm produced the highest number of pods/plant, yield did not increase due to low number of plants/unit area. Yields recorded at the Gash Delta were more than twice as much as the rainfed guar at Samsam Scheme, and similar to the irrigated guar in the Gezira. Guar is recommended as a new crop in the Gash Delta in the less-flooded areas or in the peripheries of the basins where other crops may not succeed
