Abstract

Jordan as a Mediterranean country is facing climatic change which results in increasing temperatures and a reduction in precipitation. So, there is a need to find sorghum genotypes that can resist such variations in environmental conditions. Field experiments were conducted under semi-arid conditions at the Dir-Alla agriculture research station in Jordan Valley to evaluate eight sorghum genotypes (ICSV_745, CSV_93046_9, CSV_15, JJ_1041, ICSV_112, S_35, ICSR_93034, EZRA' 7) for their stability, above-ground biomass, seed yield, and number of cuts under drought-prone environment. Results showed genotypic differences in WUE, above-ground biomass, seed yield, and HI. WUE increased with an improved HI leading to higher above-ground biomass. Linear relationships were observed between aboveground biomass, HI, and WUE. The results showed differences between the first cut compared to the following cuts. We recommend using VSV-15 with the highest value for both above-ground biomass and seed yield, followed by S_35. The S-35 showed optimistic potential to be used as fresh green forage when the whole plant is used at maturity, or can simply utilize the highest fresh weight achieved from its first cut.
