Abstract

Drought stress is one of the most important problems in crop production in arid and semiarid regions of the world the application of some materials such as SUPERABSORBENT polymers in soil could increase water retention in soil and decrease water use and fertilizer leaching. In order to study the effects of superabsorbant under under droughjt stress condition on yield, yield components and some of physiological traits of CORN (Zea mays L.) an experiment was conducted in the form of split plots in a randomized completely block design with three replications in research farm of Islamic Azad University of Birjand in 2008. Irrigation treatments with three levels (100, 70 and 40 prcents of plant water requirements) were chosen as main factors and SUPERABSORBENT with four levels (0, 35, 70 and 105 kg/ha) were chosen for subplots. Results indicated that there was a positive significant correlation between mean RELATIVE WATER CONTENT of leaf and mean CHLOROPHYLL INDEX of leaf.It was a significant positive correlation between mean CHLOROPHYLL INDEX of leaf and mean area duration of leaf (r=0.705 and r=0.883) as well. On the other hand there was a positive and significant correlation between leaf area duration and seed yield (r=0.851). It seems that DROUGHT STRESS caused a decrease in seed yield through a decrease in RELATIVE WATER CONTENT, CHLOROPHYLL INDEX and leaf area duration, and SUPERABSORBENT caused an increase in leaf area duration and consequently a higher increase in seed yield with a significant and positive effect on CHLOROPHYLL INDEX except 1678 degree growth day.
