Title
Effect of two kinds of superabsorbent on relative water content, gas exchange and yield of pishtaz cultivar in greenhouse condition
Authors
Abstract
Abstract
A greenhouse experiment was conducted as a two-factor factorial experiment based on random complete blocks design with four replications on Pishtaz cultivar in research farm of agriculture Faculty of Zanjan University in 2010-2011. The first factor was a superabsorbent including 5 levels (control, 4 grams of Stockosorb superabsorbent, 4 grams of Clophony superabsorbent, 8 grams of Stockosorb superabsorbent and 8 grams of Clophony superabsorbent in each kilograms of soil) and the second factor was stress in three levels (control, mild and severe stress). Group comparison results of two types of superabsorbent showed that Clophony superabsorbent was superior to Stockosorb superabsorbent and its effect on yield enhancement was significantly more. Also result of mean comparison showed that highest single-plant grain yield with supplying clophony superabsorbent was 8 g/kg in control condition using superabsorbent can increase rate of photosynthesis by increasing RWC, indirectly, and by enhancement of source strength cause to affecting yield.
