Abstract. The current study was held in the experimental fields of Plant breeding department, Agricultural University – Plovdiv, due 2007 till 2009. The experimental plants of Ocimum were breeded as after-harvest crop. The evaluated leaf fertilizers Hortogrow (content N:P:K – 30:20:10, microelements MgO, B, Cu, Fe, Mn, Mo, Zn; content N: P: K – 20: 20: 20, microelements MgO, B, Cu, Fe, Mn, Mo, Zn; content N: P: K – 5: 50: 20, microelements MgO, B, Cu, Fe, Mn, Mo, Zn) are applied 3 times during the vegetation, between the phases start to of branching to bloom of the 2nd stage branches. The results show a positive influence of the leaf fertilization on the production and the surface of the formed leaf. The applied technology gives the possibilities to realize more than 4 tonesfresh herba from hectare.
