چکیده مقاله :
Water sources optimizing required a suitable irrigation program. Different material can use to increase water use efficiency. Superabsorbent is one of the materials where used in around the world. These materials put in the soil and absorb water so that reserved water is usable by plant in the time of drought stress and they can reduce stress and lead to prevent yield loss. Therefore, the experiment was conducted to evaluate effects of different superabsorbent and irrigation cycles on lawn. A split plot experiment based on randomized block design with three replications was used. Irrigation cycles and superabsorbent amounts used as main-plot and sub-plots respectively. Four irrigation periods (1, 2, 4 and 6 days) and four superabsorbent amounts (0, 20, 25 and 30 g/m2) were used as experimental treatments. One-day irrigation interval and zero superabsorbent amounts were used as control. Lawn water requirement was calculate by evaporation from a pan class. Results showed that superabsorbent amount had significant effect on shoot height, total chlorophyll and plant density. Results showed that lawn performance was higher in 30 g/m2 of superabsorbent amount at two-day irrigation cycle.
