Table 2 and Fig. 2 can help us to derive that applied drip irrigation effectiveness for DI + TM, DI + BM and DI was 92% while it decreases to 57% for SI. The percent of water use reduction was 64%, 65% and 57% for DI + TM, DI + BM and DI, respectively, compared with SI. These results are also in agreement with those of Louise et al. (1999), Patel and Patel (2001) and Ghorbani (2003).
