Statistical analyses using the F-test were carried out. LSD at .01 and .05 levels was also determined. As shown in Table 3, the results surely showed significant differences in yield and WUE between treatments at .01 level, whereas transparent mulch with drip irrigation exceeded all the treatments of the study in the order DI + TM > DI + BM > DI > SI. Similar data were reported by Diaz-Perez and Batal (2002), Simms et al. (2005) and Waterer et al. (2008).
