Abstract

Reducing the losses of consumed water has always been desired by agricultural experts, one of the new methods of saving water and reducing irrigation costs is the use of superabsorbents. Since the zeolite nanoparticle has a larger specific surface area, it can absorb water and nutrients and release them when the plant needs them. A two-year greenhouse experiment was conducted to investigate the effect of different levels of irrigation and nanozeolite on growth indicators, relative water content and ion leakage in basil plants. The experiment was conducted as chopped plots in the form of randomized complete blocks with three replications, which included two treatments of irrigation and superabsorbent. Irrigation treatment includes three levels; (FC 0.75 or low irrigation), (FC or normal irrigation) and (FC 1.25 or over irrigation) and nanozeolite treatment as a superabsorbent in four levels; Z0 (no superabsorbent), Z5 (5 grams of superabsorbent per kilogram of soil), Z10 (10 grams per kilogram of soil) and Z15 (15 grams of superabsorbent per kilogram of soil) were used. The results showed that with the increase in drought severity, diameter and height growth and other traits such as the number of leaves, leaf area, weight of dry matter (biomass) of basil decreased significantly, the use of treatments Z5 and Z10 led to a significant improvement in water storage. The soil in all irrigation treatments was I1), I2, and (I3). This improvement in soil water storage subsequently led to an increase in the growth of aerial organs, growth indices of basil and its yield compared to the control treatment (Z0, Z15). This study showed It showed that there is no statistically significant difference (P>05) in product performance between Z5 and Z10 treatments.
