Abstract: 

The research was carried out in Hama countryside during the agricultural season of 2021 to study the effect of bio-fertilizer treatment (EM1) on the growth and productivity of pepper (Capsicum annum L.). Five concentrations (0 5, 7.5, 10, 15 ml/L) of bio-fertilizer (EM1) were used as foliar spray, according to the randomized complete block design, with four replications. The results of this research showed a significant increase effect of the bio-fertilizer (EM1) on vegetative growth traits (plant height, number of secondary branches and number of leaves per plant), and on production traits (fruit-set%, number of fruits per plant, average fruit weight, production per plant, and productivity of a unit area), as well as on the components of the fruits (percentage of dry matter, and the content of vitamin C) compared to the control. The T3 treatment (7.5 ml/L) was significantly superior to all treatments in all studied traits, It’s  productivity recorded 58.03 tons/ha; Therefore, it can be recommended to spray the bio-fertilizer EM1(7.5 ml/L) on the shoots to improve the growth and productivity of the pepper (Qarn Alghazal) cultivar under field cultivation conditions.

Keywords: pepper, bio-fertilizer EM1, growth traits, production traits, Capsicum annum L.
