Abstract: 

This research was carried out at the Agricultural Scientific Research Center in Homs during the year 2022-2023, in order to study the effect of foliar spraying by biological maturate( biobacter) by concentration (0 blank, 1, 2, 3) g/lit which equal the levels ( 0 blank, 50, 100, 150)% in growth and productivity Tomato plant and in the quality properties of fruits, For that completely Randomized blocks was used, and the treatments distributed by three replications,  the results gave the following: Increase the plant height  by the increasing of levels spraying comparing with the control,  the foliar  spraying by concentration 2 g/lit (treatment 100% level) outperformed the two treatments  (50, 150)% according to the number of fruits/  bunch (3 fruit /bunch), the number of fruits/ shrub (38.33 fruit/shrub), and productivity estimated with (kg/ dunum) which reached to 500kg/dunum with increasing about 50% comparing with the control. On the other hand, the result showed a decrease in the acidity of fruits, an increase in their hardness, and a decrease in the percentage of soluble soils in them when foliar spraying with biological maturate at concentration of 2 g/l (100%).

Keywords: biological maturate (biobacter), foliar spray, tomatoes, growth, productivity, quality specification.
