Abstract: In 2022-2023 a field experiment with wheat on Leached Smolnitsa was carried out in the experimental base of ISSAPP "N. Poushkarov", town of Bozhurishte, Sofia region with the purpose of testing the effectiveness of 7 types of liquid organic and mineral fertilizers, which are basically compost extracts (plant biomass) with the addition of various organic and mineral substances. The experiment was carried out in 3 replications with a plot size of 25m2 and 8 variants as follows: 1. “Sila”, 2. “Sila plus”, 3. “Sila max”, 4. “Peptone 1”, 5. “Peptone 3.”, 6.“3 Triple”, 7.“Guriy” and 8.“Control”. The tested foliar fertilizers - Sila, Sila +, Sila max, Peptone, Peptone 3, 3triple and Guriuy have a positive effect on the development of wheat even after the first foliar feeding, carried out on 24.04.2023. It has been found that all variants fed with different foliar fertilizers fall into one homogeneous group in terms of plant height. This means that only the differences between the control and the variants fed with foliar fertilizers are statistically significant and proven. The differences in yields from the variants with different foliar fertilizers are close to each other and range from 265.52 to 308.36 kg/da. The tested foliar fertilizers can successfully complement the palette of similar fertilizers offered on our market. As Bulgarian fertilizers, they could be used with advantage, because they have a positive effect during the growing season of plants and increase wheat yields. Simultaneously with their production, based on the composting of organic fertilizers and plant residues from animal husbandry and plant breeding, some ecological problems with the storage of manure and other organic waste in our country are solved.
