Response of Jatropha curcas L. to water deficit: Yield, water use efficiency and oilseed characteristics
Abstract: Field experiment was carried out at Enshas Experiment station. Jatropha was transplanted and treated after the second year of the transplanting by different amounts of water stress, vis. 125%, 100%, 75% and 50% of potential evapotranspiration (ETP). The study aims to ensure the multiple benefits of Jatropha and its suitability under Egypt's climate in unused lands under scarce water conditions. The results revealed that average water consumption rate of Jatropha is 6 L week-1 throughout the growing season, which means that Jatropha can surviv and produce full yield with high quality seeds under minimum water requirements compared to other crops. The yield extracted oil was 85.5, 175.2, 90.5 and 66.5kg ha-1 125%, 75% and 50% of ETp, respectively. The lowest values of total lipid (oil) (25% and 24.5% of Jatropha seeds) were recorder with Jatropha trees that were irrigated by 125% and 50% of ETp, respectively. On the other hand, the treatment that was imigated by 100% of ETp, (control) recorded the highest value of total oil in the seeds (29.93%). The results also revealed that are no significant differences among the values of the determined oil characteristics due to different water stress ration. From the results, it could be concluded that the highest characteristics of Jatropha seed oil were recorder with 100% of ETp, In addition water stress had significant effect on fatty acid composition of Jatropha seed oil.
