“…The decrease in the swelling capacity might be due to the increase of sodium ions outside the SAP gel which leads to lowering in osmotic pressure. The observations made in this research are in accordance with the findings of the other researchers [32][33][34].…”

The assigned study is dedicated to the synthesis, improvement and characterization of acrylic-based superabsorbent polymers (SAPs) which can be used in versatile applications notably in disposable diapers and pharmaceutics. The industrially preferred solution polymerization route and low cost monomers were used to synthesize SAPs. Homopolymer and copolymer based SAPs were prepared with varying amount of cross-linker and initiator concentrations and compared for swelling rate with a commercially available SAP sample. Swelling capacity linearly decreases with increase in cross-linker content for both the synthesized SAPs samples whereas it first increases and then decreases with initiator content for the synthesized copolymer SAP. Swelling kinetics of the synthesized and commercial SAPs were modelled using model equation proposed by Omidian et al. Both the synthesized SAPs showed substantial increase in swelling capacity whereas copolymer SAP exhibited the highest swelling rate (rate parameter 2.78 min) when compared to homopolymer SAP and the commercially available SAP samples. Accordingly, the copolymer SAP may find its application in disposable diapers or pharmaceutics where the higher swelling rate is of prime importance. Copolymer and commercially available SAPs depicted significant decrease in swelling capacity even at very low saline solution concentration (0.01 %).

Superabsorbent polymers (SAPs) have been used as water-saving materials for limited irrigation water resources in arid and semi-arid areas. The purpose of this study was to optimize SAP application dosage and irrigation intervals on the growth of African leafy vegetables (ALVs) under greenhouse conditions. A factorial experiment was conducted under greenhouse conditions to determine the optimal SAP application, dosage, and irrigation intervals for the growth and production of African leafy vegetables. Two species of African leafy vegetables were studied: cowpea (Vigna unguiculata) and African nightshade (Solanum scabrum). The experiment was performed in a randomized complete block design comprising 25 treatments: a factorial combination of five superabsorbent polymer application doses (0 g, 0.5 g, 1 g, 1.5 g, and 2 g) SAP/Kg of soil substrate and five irrigation intervals (3 days, 4 days, 5 days, 6 days, and 7 days) with three replications. Statistical analysis of the results showed that the use of SAP in irrigation can significantly promote the growth and yield of African leafy vegetables. SAP, irrigation, and their interactions significantly affected ( P < 0.005 ) the plant height, stem diameter, leaf area, number of mature leaves/plant, and dry weight of leafy vegetables. Treatment with SAP showed higher growth parameters and yield of vegetables compared to the treatments. Treatment with 1 g SAP/kg of soil substrate and 5-day irrigation interval recorded the highest plant growth and yield, with 24%, 11.7%, 11.1%, and 85.9% increase in cowpea plant height, leaf area, number of mature leaves, and dry weight/plant, respectively. The treatment with 1 g SAP/kg of soil substrate and 5-day irrigation interval was observed as the best for the optimal production of African leafy vegetables under greenhouse conditions. Hence, SAP could be a good strategy for food production within arid and semi-arid lands where water resources are scarce.

“…Yield production and genetic parameters could be affected by drought stress (Huang et al 2021;Qin et al 2021;Yin et al 2021;Gholamin and Khayatnezhad 2021;Bi et al 2021). Superabsorbent polymers were considered as water retaining materials in agricultural fields to release stored water as required by the plants (Fallahi et al 2015;Al-Obaidy et al 2019). Several studies have been carried out on superabsorbent application to improve soil water capacity for different crops (Moslemi et al 2012;Fernando et al 2013;Fallahi et al 2015;Ghanbari and Javan 2018;Al-Obaidy et al 2019).…”

Soil moisture capacity improvement could be a solution to increase the water productivity under drought condition. In this study, a try has been made to evaluate the influence of the superabsorbent polymer as a soil humidifier to increase root zone moisture content for maize cultivation. Field experiments were established in the Gotvand region of Khuzestan province, Iran. Three treatments of Aquasorb 3005 application (0, 300, and 600 kg/ha) and four irrigation strategies were considered in three replications for two growing seasons of 2019 and 2020 (from March to July). Irrigation planning, cultivation costs, biomass, harvest index and canopy cover were measured at different time steps of the growing seasons to provide growth simulation models using AquaCrop software. Minimum error test showed that the use of Aquasorb 3005 increased the yield of the product at 1% confidence level. Moreover, the depth and timing of irrigation were optimized by whale optimization algorithm with the objective of maximization of biomass under the water resources and economic constraints. Results illustrated the influence of superabsorbent application and irrigation planning on the improvement of water productivity.
