Резюме: In a field experiment with corn on Leached Smolnitsa in an experimental base of ISSAPP "N. Pushkarov", Bozhurishte, Sofia region, brought out for the purpose of testing the action of 3 types of liquid complex fertilizers, their positive influence on the development of corn has been established. Fertilizers are obtained by extracting compost from plant biomass with the addition of various mineral substances. The size of the plots is 25m2 in 3 repetitions and 4 variants, as follows: 1."Strength Plus", 2."Strength Max", 3."Matthew", and 4." Control". The tested foliar fertilizers – Strength Plus, Strength Max, and Matthew positively affect the development of corn only after the second and especially after the third foliar feeding, carried out on 24.07.2023. This is evidenced by the measured plant heights, which show that all variants fall into one homogeneous group and the differences between the individual variants are not proven statistically. The third feeding with the tested foliar fertilizers (08.08.2023) significantly contributes to obtaining higher yields of corn in these variants when harvesting the experience (12.10.2023). The effect of liquid fertilizers through the resulting corn yields has been statistically proven. It has been found that all variants fed with different foliar fertilizers fall into 2 different homogeneous groups - B and C. This means that the differences in yields between the control and the variants are statistically significant and proven. The differences in yields from the variants with foliar fertilizers strength plus and strength max are close to each other, vary in the range from 5336 to 5337.4 kg/ha and fall into homogeneous group B. The most favourable effect is exerted by foliar fertilizer Matthew, in which, after its three applications, the highest yield of corn was obtained - 6054.13 kg/ha.
