The effect of soil type, moisture content and the amount of superabsorbent material on the corn plant height and leaf area

Kerman province with mean annual precipitation about 130 mm is categorized among dry provinces.Then producing the maximum agricultural products using minimum water consumption is highly important increasing soil water content and preventing of water deep.Percolation is one of the best ways to use water more efficiently in agricultural practices. In this regard using super absorbent gel is one of the newest methods that. Some studies have been carried on it.In a greenhouse test the effect of soil type , percent of soil moisture content and the amount of super absorbent in a purely random test of factorial with three factors : soil type ( heavy or light ) , percent soil moisture and the amount of super absorbent ( 0 , 100 , 200 , 400 , 800 , kg/ha ) , the effect of them evaluated on the height of maize , and surface of plant . The effect of soil type.  Percent of soil moisture and the amount of super absorbent showed significant difference on plant height and inflammation of leaf.The best results on growing factor of the plant achieved by using 400 kg of s.j in light soil with 60 % of soil water content.
