Abstract<\/p>\n
\u00a0 A field experiment was conducted to study the effect of inorganic fertilizer of Agro leaf and Magnesium in some vegetative growth and chemical contents of Summer Squash (Cucurbita\u00a0 pepo<\/em> L.)\u00a0 Randomized Complet Block Design was used with three replications. Three concentrations of Agro leaf ( 0, 15\u00a0\u00a0 ,30 ) gm L -1<\/sup> were sprayed on plants. Four concentrations of Magnesium ( 0 ,0.75\u00a0 ,1.50 and 2.25 mM) were also sprayed. The most effective Agro leaf \u2013 foliar nutrition treatment was\u00a0 (30)\u00a0 gm l -1<\/sup>),\u00a0 which caused significant differences in total chlorophyll 33.84 SPAD, Leaf area 1.16 m 2<\/sup>, leaf plant -1<\/sup> 32.40, \u00a0K and\u00a0 Mg in leaves 2.91 and 0.25 {8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}, respectively. The lowest values of detected parameters were confined to control. Spraying with magnesium at 2.25 mM significantly increased leaf area 1.32 m2<\/sup>. Interaction between Agro leaf and Magnesium A3Mg4 significantly increased all investigated traits.<\/p>\n Baqer Challab Hadi AL-Rubaye*<\/p>\n College of Science AlMuthanna Univ<\/p>\n
