Hybrid seeds influence seedling vigor in forage sorghum and corn. Few investigations were reported on the hybrid effect on vigor for irrigation conditions in Jordan. A new investigation conducted under the Norman Borlaug fellowship during 2017 demonstrated a suitable simulation for growers. The first step required the identification of drought-tolerant seeds. Five commercial seed lots (three of corn and two of sorghum) were used. The second involved planting seeds under controlled and field conditions in the Florida A&M University and then evaluating the vigor by measuring emergence, fresh weight, and water use efficiency. Corn (6640VT3P) had significantly higher fresh weight and vigor. However, it was significantly the highest with water use efficiency in the greenhouse. The superiority of corn (6640VT3P) may be attributed to increased seed weight. Thus, results reported suggest that corn (6640VT3P) had a high impact on the seedling establishment that could be grown under extreme drought conditions.
