Growth of Some Sugar Beet Varieties Under Different Locations as Affected by Foliar Application with Salicylic Acid on Yield and Quality

Two field experiments were conducted to evaluate the effect of foliar application salicylic acid (SA) on growth, yield and quality characters five sugar beet varieties (MARWA KWS, SUGAR KING, MiRAGE, DREEMAN ESTORA KWS) under two types soil in different locations Nubaria Sakha regions during 2018/2019 2019/2020 seasons. The split-split plot design three replications, where main plots assigned by (sandy clay Sakha), while subplots occupied concentrations SA (control, 1000 2000 ppm) (Marwa kws, Sugar king, Mirage, Dreeman Estora kws) allocated randomly sub- subplots. results revealed that ppm significantly influenced top fresh mass root biomass plants. Conversely, increasing concentration led significant differences mass, yield, sucrose % as well purity both  The kws exhibited better performance terms length conditions. interaction between factors gave maximum levels increment for most studied characters, particularly cultivar KWS.
