Abstract: With increasingly obvious effects of global warming, nations across the world, including the UAE newlineare looking for green energy sources to supplement or replace their fuel needs. In this thesis we newlinecompared three candidate bio-diesel feedstock crops, Ricinus communis, Citrullus colocynthis and newlineBrassica juncea in terms of their salinity tolerance, oil yield and oil quality when cultivated in the newlinearid and saline conditions of the UAE. Eleven accessions of Ricinus communis, thirty-seven newlineaccessions of Citrullus colocynthis and five accessions of Brassica juncea were studied in field newlinetrials with triplicates conducted at the International Center for Biosaline Agriculture (ICBA) newlineresearch station in Dubai over a single season each. Three salinity treatments, at 5, 10 and 15 dS newlinem-1 were applied and response to salinity was observed by analyzing K+/Na+ ratios in leaf tissue newlineusing ICP-OES. Seed and oil yield was recorded and solvent (n-hexane) extracted oil was analyzed newlinefor free fatty acid content, saponification value and kinematic viscosity in order to determine newlinesuitability of oil for bio-diesel production. The data obtained was statistically analyzed using newlinemethods such as ANOVA, Pearson correlation matrices, Principal Components Analysis and newlineHeirarchical Clustering. Among the crops studied, no significantly salt tolerant accession was newlinefound. Extrapolated seed yield of Ricinus communis was between 1.5 and 3 tonnes/ha in the newlinecontrol treatment, and between 1.8 and 2.3 tonnes/ha in the 5 dS m-1 treatment, which was not newlinedifferent to a statistically significant degree. The lack of significant effect on inflorescence newlinecharacteristics and seed yield at 5 dS m-1 in spite of sodium ion accumulation was an interesting newlineobservation.
