ABSTRACT
A field experiment was conducted to study the effect of inorganic fertilizer of Agro leaf and Magnesium in some vegetative and chemical growth
of Summer Squash ( Cucurbita pepo L . Randomized Complet Block Design was used with three replications . Spraying three concentrations of Agro leaf ( 0, 15 ,30 ) gm L -1 which were ( A1 , A2 , A3 ) respectively , and four concentrations of Magnesium ( 0 ,0.75 ,1.50 and 2.25 )mM which were ( Mg1 , Mg2 , Mg3 , Mg4 ) respectively . Result showed that the suitable Agro leaf – foliar nutrition treated was (30) gm L -1 which caused significant differences in Total chlorophyll 33.84 SPAD , Leaf area 1.16 m 2 , No. of leaves 32.40 leaf plant -1 , K and Mg in leaves 2.91 % and 0.25 respectively , there was no significant differences between (15 and 30 ) gm L -1 in N , P in leaves , % protein and plant yield . The least result in all characteristics in this study was in control treatment . Spraying with magnesium at 2.25 mM significantly increased leaf area 1.32 m2 . Interaction between Agro leaf and Magnesium A3Mg4 was significant in all the chracteristics of this research |
