Abstract:

In order to evaluate the effect of switching the furrow to drip irrigation methods on stem length, water used efficiency (WUE) and depth of root zone of Sultana grapevines, an experiment was conducted based on a randomized complete block design with four replicates in 2015-2016 growing season in Malayer, Iran. Treatments were: furrow irrigation (I1), combination of drip and furrow irrigation system (drip-furrow) (I2), bubbler irrigation (I3), drip 1: three dripper/plant (I4), surface-subsurface drip irrigation (I5), drip 2: five dripper/plant (I6) and drip 3: -eight dripper/plant (I7). The results showed that the drip irrigation caused significant decrease in the shoot length, leaf area and water consumption compared to the furrow irrigation. In the same order, the average of the mentioned parameters for furrow irrigation were 133 cm, 11.1 m2/vine and 5337m3/ha respectively, and for the drip irrigation, 121 cm, 6.5 m2/vine and 3625 m3/ha. These results indicated that there was positive correlations (R2) between the mentioned parameters. The treatments I6 and I7 had a yield of 31 and 29 ton/ha respectively, exceeding the furrow irrigation with yield 24 ton/ha. However, the other drip irrigation treatments showed less yield than furrow irrigation. The maximum WUE was evidenced by I6 treatment (10.3 kg/m3) and the minimum by furrow irrigation (4.9 kg/m3). The results showed that I6 with five dripper/plant, was the most efficient treatment, so it was considered an appropriate irrigation method to change from furrow to drip irrigation. At the end of the experiment, samples were taken from the vine roots revealing that the drip irrigation systems caused shallow roots.
