Abstract
Abstract Two open-field experiments were conducted during 2021 and 2022 to study the impacts of the foliar supplementation of different sources of magnesium fertilizer on green onion vegetative growth, spectral reflectance indices (SRIs) such as atmospherically resistant vegetation index (ARVI), normalized difference vegetation index (NDVI), soil-adjusted vegetation index (SAVI), disease water stress index (DSWI), and modified chlorophyll absorption ratio index (MCARI), and yield quality. Treatments included: (1) magnesium sulfate (as control is CT, at a rate of 300 cm3/fed), (2) magnesium nitrate at a rate of 300 cm3/fed), (3) magnesium phosphates at a rate of 300 cm3/fed, and magnesium oxide nanoparticles (MgO-NPs) at a rate of (100 ppm/fed). The results obtained showed that the spraying of MgO-NPs and magnesium phosphates significantly increased the plant height, chlorophyll a and b, number of leaves and fresh weight compared to the control treatment (CT) in both seasons. Furthermore, the foliar application of MgO-NPs improved the accumulation of N, P, K and Mg content in onion plant compared to the control treatment. Foliar application of MgO-NPs significantly increased the yield of green onion by 45.97% in the first season and 45.7% in the second season, respectively. Also, maximum concentration of protein content, free amino acids (FAA), total flavonoid content (TFC), total phenolic content (TPC) and total soluble solids (TSS) were observed in plants treated with MgO-NPs followed by magnesium phosphates compared to the control treatment. Magnesium oxide nanoparticle treatments significantly improved the values of vegetation indices development, leaf area index (LAI), and absorbed photosynthetically active radiation (FAPAR). Convincingly, the foliar application of MgO-NPs fertilizer is a favorable technique to enhance morphological parameters, production and onion quality in sand soil.
