ALLAHYARI, S., GOLCHIN, A., VAEZI, A., 2013. STUDY ON EFFECT OF SUPER ABSORBENT POLYMER APPLICATION ON YIELD AND YIELD COMPONENTS OF TWO CHICKPEA CULTIVARS UNDER RAINFED CONDITIONS. Thirty-six undisturbed soil lysimeters were installed in a field lysimeter facility in drought-affected northern China to study the growth and yield characteristics of summer corn (Zea mays L.) as well as the amount of NO3-leaching losses under different fertiliser (standard, medium or 75% and low, or 50% of conventional fertilisation rate) and SAP (control, 0; level-1, 15 kg ha−1 and level-2, 30 kg ha−1) treatments. BACKGROUND: The objective was to study soil water conservation and physiological growth of corn (Zea mays L.) using water-saving super-absorbent polymer (SAP) at 30 kg ha−1. CONCLUSIONS: Our results suggested that plant growth and different physiological activities are restricted by drought stress and the application of super-absorbent polymer could conserve soil water, making same available to plants for increased growth and biomass accumulation especially under severe water stress. Super-absorbent polymer refers to a plastic that can absorb large amounts of liquid - up to 1,000 times its own weight.

It was possible to conclude that, under drought stress conditions, the super absorbent polymer application, for reserving higher amounts of water in itself, increased the soil ability to store water, what increased the plant vegetative period and consequently the oil quality by decreasing saturate fatty acids and increasing unsaturated fatty acids. potassium acrylate was conducted to evaluate the effect of six oilseed rape (Brassica napus L.) genotypes (Rgs003, Sarigol, Option500, Hyola401, Hyola330, and Hyola420), with and without drought stress, and with and without the use of super absorbent polymer, on oil quality and content. Results showed a significant difference for drought stress levels, presence of super absorbent and genotypes on oil content and composition, as well as on glucosinolate content in the oil. Similarly, plant height, leaf area, number of grains as well as protein, soluble sugar and starch contents in the grain also increased with SAP treatment. Other materials are also used to make a superabsorbent polymer, such as polyacrylamide copolymer, ethylene maleic anhydride copolymer, cross-linked carboxymethylcellulose, polyvinyl alcohol copolymers, cross-linked polyethylene oxide, and starch grafted copolymer of polyacrylonitrile to name a few. On ASU’s 12-acre field, the gel may be able to save a few million gallons of water a year.

The baby is not left wet even for few minutes if you are using disposable product for him. Photocatalytic regeneration of spent JS using UV/TiO2 is more effective compared to conventional methods. Today superabsorbent polymers are made using one of three primary methods: gel polymerization, suspension polymerization, or solution polymerization. Thus sodium acrylate segment dominated the global superabsorbent polymers market with USD 3.98 billion revenue in 2017. Polyacrylamide copolymer segment is anticipated to grow at a CAGR of 8.35% over the forecast period. The major players in global Superabsorbent Polymers market include BASF SE, Nippon Shokubai Co. Ltd., Formosa Plastics Corporation, LG Chemical Ltd., Sumitomo Seika Chemicals Co. Ltd., SDP Global Co. Ltd., Songwon Industrial Co. Ltd., KAO Corporation, Evonik Industries AG, Yixing Danson, Archer Daniels Midland Company, Acuro Organics Ltd, Chemtex Specialty Ltd., Emerging Technologies Inc, Quanzhou Banglida Technology Industry Co. Ltd., Shandong Nuoer Bio-Tech Co. Ltd., Shanghai Huayi Acrylic Acid Co. Ltd., Sikko Industries, Tangshan Boya Resin Co. Ltd., Y&X Beijing International Trade Co. Ltd., Zhejiang Satellite Petro-Chemical Co. Ltd. An alternative management method could be the valorisation of the biodegradable material through anaerobic digestion, and the recycling of plastics and SAP. Super absorbent polymer (SAP) is a new type of multifunctional material in drought resistant and pollution control.

Their superior swelling abilities originate from the electrostatic repulsion between the charges on the polymer chains and the osmotic imbalance between the interior and exterior of the gels3. Odor reducing agent for superior odor control. The results for plant height, plant dry weight, boll number per plant and fiber yield in this treatment were 16, 28, 42 and 10% higher than control treatment, respectively. STUDY ON EFFECT OF SUPER ABSORBENT POLYMER APPLICATION ON YIELD AND YIELD COMPONENTS OF TWO CHICKPEA CULTIVARS UNDER RAINFED CONDITIONS. The SAP had little effect on shoot dry mass under adequate and moderate irrigation but increased it significantly by 133.5% under deficit irrigation. In order to investigate the effect of water deficit, irrigation after 120 (control), 155 (moderate water stress) and 190 mm (sever water stress) pan evaporation and super absorbent polymer rates (SAP) (0, 30, 60 and 90 kg ha-1) on growth, yield and water use efficiency of cotton, an experiment was conducted as split plot based on a randomized complete block design with three replications.
