Abstract

Background and Objective: Due to scarcity of water in most regions of Iran, the use of superabsorbent polymers is known as a helpful approach in improving soil physical and chemical properties, soil fertility and water resources storage. The purpose of this study was to examine the effect of Pumice on Water Availability, chemical and nutritional properties in a course and fine textured soils under Onion cultivation. Method: This research, was conducted in spring of 2017 in greenhouse as factorial in form of CRD design with three factors including Soil Texture (with two levels: sandy loam and clay loam), irrigation schedule (with two levels: every 4 and every 7 days) and Pumice (with four levels: 0 (C1), 2. 5 (C2), 5 (C3) and 7. 5 (C4) percentage w/w) which were carried out in three replications. Findings: Results, showed that increasing Pumice rate, could increase P, K, S, Fe, Mn and Zn concentration in Onion. In most cases, there was no significant difference between 5 and 7. 5 percentages of Pumice rates. Positive effect of Pumice in sandy loam soil was more than clay loam. In Pumice treatments, there was no significant difference between two irrigation rates, for none of parameters except for Cu concentration in plant. Discussion and Conclusion: By Application of 5 percentage w/w Pumice in soil, irrigation schedule of Onion could be increased from 4 days to 7 days. Noting that the irrigation schedule is one of the most important factors in Onion cultivation, Pumice application, can cause a good economic efficiency in water use.
