Three types of pitchers made of different materials were used with saline waters of varied concentrations (5, 10, 15 and 20 dS m-1)
separately to study the effect on flow rate, wetting front advance, moisture and salt distribution in the wetted zone of soil around
pitchers. It was found that the pitcher made of clay and sand yielded the lowest flow rate, ranging from 0.42 to 0.62%, followed
by the pitcher made of clay, sand and resin, 0.51–0.69% and the pitcher made of clay, sand and sawdust, 0.91–1.02% .The wetting
front advance was highest for the pitcher made of clay, sand and sawdust, followed by the pitcher made of clay, sand and
resin, and the pitcher made of clay and sand. The mean soil moisture content around the pitcher made of clay and sand was found
to be the minimum and varied from 8.53 to 13.3%, followed by the pitcher made of clay, sand and resin, and the pitcher made of
clay, sand and sawdust with 9.56–13.7% and 14.5–20.8%, respectively. In the case of the pitcher made of clay and sand, and the
pitcher made of clay, sand and resin, the maximum salt concentration in the soil profile ranged between 1.09 and 3.88 dS m-1 and
in the pitcher made of clay, sand and sawdust, it ranged from 2.30 to 6.07 dS m-1. The initial salinity of water was found to be
substantially reduced around the pitcher made of clay and sand, and the pitcher made of clay, sand and resin in comparison to the
pitcher made of clay, sand and sawdust. In all cases, salinity levels around the pitchers were well within the safe limit of growing
crops. The study reveals that pitcher irrigation may be a promising option for growing plants using highly saline waters, sustaining
hardly any salinity hazard or moisture stress. Copyright © 2013 John Wiley & Sons, Ltd.
