“…4 F, there was a significant negative correlation between zinc content and malondialdehyde (MDA) content in rice leaves in saline-sodic land. In recent years, the green synthesis of nanoparticles has attracted much attention because of its advantages of low cost, simplicity and environmental protection 37 . This study found that ZnO NPs was more conducive to the absorption of zinc in rice and had a better alleviation effect on saline-sodic stress.…”

Saline-sodic stress restricts the absorption of zinc by rice, consequently impacting the photosynthesis process of rice plants. In this experiment, Landrace 9 was selected as the test material and the potting method was employed to investigate the influence of ZnO nanoparticles (ZnO NPs) on zinc absorption and chlorophyll fluorescence in rice grown in saline-sodic land. The research findings demonstrate that the application of ZnO NPs proves to be more advantageous for the growth of rice in saline-sodic soil. Notably, the application of ZnO NPs significantly decreases the levels of Na+ and MDA in rice leaves in saline-sodic soil, while increasing the levels of K+ and Zn2+. Additionally, ZnO NPs enhances the content of chloroplast pigments, specific energy flux, quantum yield, and the performance of active PSII reaction center (PIABS) in rice leaves under saline-sodic stress. Furthermore, the relative variable fluorescence (WK and VJ) and quantum energy dissipation rate (φDo) of rice are also reduced. Therefore, the addition of ZnO NPs enhances the transfer of electrons and energy within the rice photosystem when subjected to saline-sodic stress. This promotes photosynthesis in rice plants growing in saline-sodic land, increasing their resistance to saline-sodic stress and ultimately facilitating their growth and development.

HE DEGRADATION of soil characteristics caused by salinity and sodicity gives rise to severe limitations on crop production. Therefore, the current study was conducted in a split block design with three replicates during the winter (2019/2020) and summer (2020) seasons at Sakha Agriculture Research Station Farm, Kafr El-Sheikh Gov., Egypt to study the integrated effect of gypsum with mycorrhizae fungi inoculation to improve saline-sodic soil properties and bacterial communities, physiological and productivity of wheat and maize plants. The treatments included different soil gypsum levels (G 0 : none, G 1 : 7.5 Mg ha -1 , and G 2 : 10 Mg ha -1 ) of the requirements and mycorrhizal fungi inoculation (without inoculation AMF 0 and inoculated AMF 1 ). The results showed that the combination of G 2 + AMF 1 caused significant changes in the photosynthetic activity, antioxidant enzyme activities (catalase, peroxidase and superoxide dismutase), mycorrhizal root colonization, total bacterial counts, P solubilizer bacteria, and respiration of microbial soil in the Rhizosphere of wheat and maize. In addition, after two growing seasons, electrical conductivity (EC) decreased from 7.09 to 4.57 dS m -1 , exchangeable sodium percentage (ESP) from 19.35 to 15.47 and soil bulk density (BD) from 1.38 to 1.31 Mg m -3 . While the exchangeable calcium percentage (ECaP) increased from 11.51 to 15.47, available phosphorus (Av. P) from 8.19 to 11.17 mg kg -1 , infiltration rate (IR) from 0.7 to 0.97 cm hr -1 , and total porosity (TP) from 47.92 to 50.44 % and G 2 + AMF 1 treatment gave the highest grain yield of wheat and maize were 7.72 and 8.52 Mg ha -1 , respectively. Current findings concluded that the incorporation of gypsum application with AMF inoculation could be applied as an effective way of ameliorating saline-sodic soil characteristics and alleviating the hazardous effects of soil salinity and sodicity on wheat and maize plants.

“…Several studies have examined the combined effect of gypsum and sulfur addition on plant growth and reported similar findings. El- Mogy et al (2018) found that the combined application of gypsum and sulfur significantly improved the plant height, leaf area, and grain yield of maize. El-Ghandour et al (2020) reported that the combined application of gypsum and sulfur to a saline soil significantly improved the growth and yield of wheat.…”

The study was carried out using salt-affected soils were taken from different five locations of Sakha, Kafr El-Sheikh Governorate, north Nile Delta, Egypt to study the effect of gypsum or sulfur, each individually or in combination, on the growth and N, P, K contents of barley plants (Hordeum vulgare L.). The results demonstrated that the addition of both gypsum and sulfur, individually or in combination, had a significant effect on the barely dry weight (BDW), with higher levels of gypsum and sulfur resulting in higher BDW values. There are some variations among the soil types for N, P K and S contents (%). The mean concentrations of N, P, K, and S across all studied soils are 0.147%, 0.289%, 1.450%, and 0.465%, respectively. The highest N and P concentration (0.155%) and (0.319%) are found in Soil 2 and soil 4, respectively. The mean uptake of N, P, K, and S across all studied soils are 4.24, 7.70, 41.84, and 13.22 mg/pot, respectively. The application of elemental sulfur and gypsum increased both the concentration and uptake of N, P, K and S for barley plants compared to the control.
