Abstract:To explore effects of regulated deficit irrigation and nitrogen nutrition on growth and water use efficiency of Jatropha curcas L., a set of pot experiments are conducted at four water levels(WLWH, WHWL, WLWL, WHWH)and three nitrogen levels(NZ: 0, NL: 0.2 g/kg, NH: 0.4 g/kg). It is shown that the growth and irrigation water use efficiency at WLWH levels are significantly higher than WHWL. With increasing nitrogen level, the irrigation water use efficiency shows a maximum value at NL level. Compared with NHWHWH, the height, total dry matter and irrigation water use efficiency are decreased by 31%, 35% and 13%, irrigation water is saved by 27%, and nitrogen fertilizer dosage is reduced by 50%, respectively, at NLWLWH levels, but the plant stem diameter, root-shoot ratio are increased by 13% and 20%. In the first stage of growth(40-90 d), less water is demanded, moderate deficit irrigation can improve the irrigation water use efficiency. In the second stage of growth(90-140 d), more water is on demand for vigorously growing, increasing irrigation water can promote plant growth and dry matter accumulation greatly. Even though a deficit irrigation in the whole growth period can improve the ability to adapt to the environment, the plant production decreases. After a comprehensive analysis, NLWLWH is the best irrigation and nitrogen fertilization scheme under arid area conditions for Jatropha curcas L.
