Abstract
Field trials for two seasons (2020-2021 and 2021-2022) were conducted to investigate the influence of canal water, agricultural drainage water, and different concentrations of silver nanoparticles (AgNO3NPs) (0, 60 and 75 ppm), humic acid (0,6 and 8 kg/fed) and sulphur (0, 200 and 400 kg/fed) on yield, quality characteristics, and production of sugar beet under the conditions of the salt-affected soil. Each field experiment included two factors in a split-plot design with three replications. The main plots were assigned to water irrigation treatments; whereas the rates of soil amendment (silver nanoparticles, sulfur, and humic acid) were arranged randomly within the sub-plots. Each subplot included six ridges which were 0.50 m apart and 3.50 m in length; so, the area of each subplot was 10.50 m2 (1/400 fed.). The most important results revealed that the canal water led to significant improvements in all traits of root yield, top yield, quality, gross yield, and pure sugar. In addition, increasing soil amendment (sulfur, humic acid, and silver nanoparticle) fertilization decreased significantly potassium (%), -α amino nitrogen (%), and sodium (%) in sugar beet root; however, the highest mean values of the sugar yield, and white sugar yield were recorded under the irrigation with canal water or drainage water with the application of 75ppm silver nanoparticles Meanwhile the lowest previous mentioned characters were obtained under irrigation with drainage water and control treatment (without any addition of soil amendments), during the two seasons. This showed that soil amendments (sulphur, humic acid, and silver nanoparticles) fertilization and irrigation treatment acts dependently on the sugar yield of the sugar beet plant under this study.
