Abstract
In order to study the effects of different nitrogen and irrigation water patterns on water and nitrogen use efficiency of Jatropha curcas L., three water levels (W1:100% ET (ET as evapotranspiration), W2:80% ET, W3:60% ET), and three nitrogen application levels (N1:0g.kg-1, N2:0.4g.kg-1, N3:0.8g.kg-1) were designed. The results showed that compared with T1, each organ and total dry matter of Jatropha curcas L. decreased in T2 and T3. Besides, nitrogen application significantly increased each organ and total dry matter of Jatropha curcas L. Compared with W1N3(high water and nitrogen content), W2N2 treatment saved 20% water and 50% nitrogen fertilizer. Its irrigation water uses efficiency and total amount of nitrogen uptake in per plant increased by 26% and 64.88%. Therefore, W2N2 treatment is the best irrigation and nitrogen application pattern for the growth, the use efficiency of water and nitrogen of Jatropha curcas L.
