Abstract: 

This research was carried out during the agricultural season 2019-2020 at the Agricultural Scientific Research Center in Homs at the Irrigation Research Station in Mokhtaria, in order to study the effect of Foliar application with elements of zinc(as sulphate of Zink 13%)  and boron(as borax fertilizer17%) separately or together in some growth indicators(length of plant, leaf’s area, number of pods on plant, weight of 100 seed, weight of seeds on plant and in the productivity of two varieties of soybeans(secondary factor), the promising variety Sb239 And the variety Ascrewe3803, spilt plot design with four treatments(main factor) was used as fallowing, spraying, zink and boron togther(B₂Zn₂), boron without Zink(B₂Zn₀), zink without boron(Zn₂B₀), and blank without boron and zink(B₀Zn₀), the treatments were added as concentration of 2g/liter, and the results showed, an increase in, the length of the plant, area of leaf, the number of pods, and significant increasing on some seed indicators, as a weight of 100 Seeds and weight of seeds on plant, at the two studied varieties in general and the highest percentage was when spraying the elements boron and zinc together, and the value of  increasing in all studied indicators at the variety Sb239 was bigger than it’s value at the variety Ascrewe3803, On the other hand, Soybean yield increased in the studied varieties Sb239 and Ascrewe3803 when spraying boron, zinc by all studied levels (Zn₂B₂, Zn₀B₂, Zn₂B₀), which significantly outperformed the blank (without spraying), Where the highest increase in productivity was when spraying the elements zinc and boron together which reached to (61%) at the variety Sb239 and (57%) at the variety Ascrewe3803, also the results showed, the response of the soybean variety Sb239 when spraying the elements boron and zinc at all studied levels (Zn₂B₂, Zn₀B₂, Zn₂B₀)greater than the Ascrewe3803 variety response at all studied growth indicators as well as in productivity estimated in kg / ha.

Keywords: Soybean, variety Sb239, variety Ascrewe3803, Borax, Sulphate of Zinc, Growth Indicators, Productivit.
