Abstract
ABSTRACT Scarcity of water is a substantial impediment to the growth and yield of crop species. In this study, free-radical copolymerization was used to tailor novel formulations of superabsorbent nanocomposites (SANCs). The prepared SANCs were characterized using FT-IR spectra, SEM micrograph, TGA and X-Ray diffraction. Following SANC preparation, the swelling behavior was examined. Also, SANC's soil burial degradation and water retention were investigated. A pot trial was performed to examine the growth performance and physio-biochemical traits of Faba bean in the presence and absence of SANC under water-stress (40% FC). Water stress decreased chlorophyl and sugars contents, CAT, APX, SOD, and PPO activities. Nonetheless, water stress raised POD and GR activities, and AsA, DPPH, PMA, H2O2, MDA, and soluble proteins levels. SANC alleviated water stress by boosting Faba bean growth and physiological characteristics. SANC enhanced Chl b, carotenoids, Fv/Fm, CAT, GR and SOD, contributing to better growth of stressed Faba bean.
