Effect of Different levels of Super Absorbent Polymer and Water Stress on Yield Components of of Forage Corn

Super absorbent polymers because of Water absorption and hold water can increase the water-holding capacity of the soil and decreases tension caused by dehydration effect. This study evaluated the effects of different levels of superabsorbent polymer and water stress on yield components in maize In Agriculture Research Center of Varamin city in July 2012 Was carried out as a pot factorial complete block randomized design with 3 iteration. Treatments consisted of four levels of water stress، w1، w2، w3 and w4 (50، 75، 100 and 125% of crop water requirement) and 4 superabsorbent Hybrozom s1، s2، s3 and s4 (control، 3، 5، 7 grams per kilogram potting soil). Traits Review was Included: Length of Bush، Fresh weight of leaves and Dry weight of leaves. The Results indicated that، with increase rate of superabsorbent polymer was increased leaf dry weight، total dry weight and plant height so that this parameters in the treatment s4 (7 grams per kilogram of soil) than controls، respectively 63. 72، 90. 14، 36. 42 percent has increased.
