Abstract: 

The research was carried at Baksa village in Sitmarkho-Lattakia governorate on the Syrian coast, during the agriculture season 2021 by the cultivation of soybean (Glycine max L.) seeds (Sb44) in experimental plots, according to the randomized complete block design (RCBD) and with three replicates. The objective of this research was to study of effect of foliar spraying treatments with organic fertilizer Magic Grow^® (MG) (0, 1, 5 and 10 g/L), and with organic fertilizer MELBOPHOS^® (MB) (Molybdenum, boron and phosphorus) (0, 0.5, 1 and 1.5 ml/L), and the combined effect of spraying with the organic fertilizers MG and MB together on some growth, productive and qualitative characteristics of the studied variety. So, the plant height (cm) and a number of indicators were measured: plant leaf area (cm²), leaf area index (LAI), crop growth rate (g/m²/day), leaf chlorophyll and carotenoids content (µg/g FW), number of pods (pod/plant), seeds weight (g/plant), 100 seeds weight (g/plant), productivity (kg/1000 m²), clearance ratio (%) and total seeds content of protein and soluble sugars (%). The MG spray treatments, especially at concentrations 5 and 10 g/L, and spraying with MB at concentrations 0.5 and 1 ml/L led to a significant increase (P<0.05) in most of growth and productive characteristics. Also, the combined effect of spraying treatments with both organic fertilizers (5 and 10 g/L) MG and (0.5 and 1 ml/L) MB showed a significant increase (P<0.05) in the growth and productivity of plant. Thus, it can be suggested to spray soybean (Sb44) with MG at 5-10 g/L and MB at 0.5-1 ml/L due to their observed role in improving the vegetative growth parameters and seed yield, hence the possibility of growing soybeans (Glycine max L.) in the coastal zone conditions.
