The effect of sandy soil treatment with superabsorbent polymer(0.1,0.2g/kg)on
infiltration rate and shoot and root growth of green pepper at two soil levels (80and
100%)of field capacity was studied.
The results indicate that sandy soil treatment
with polymer (0.1 and 0.2
g/kg)decreased infiltration rate by 41.1 and 50.9% alternatively compared to the control.
Germination rate, plant height ,leaf area, shoot and root dry weight were increased
significantly with polymer treatment compared to the control and mineral fertilization
treatment ,but that difference was not significant among field capacity levels (80and 100%)
Treatments with hydrogel (0.1,0.2g/kg)decreased water need to produce a unity of
shoot dry matter and economized water by 50 and 65%compared to the control.
