Vermicompost or earthworm humus is a new generation, organic fertilizer, produced with the help of earthworms. It is a concentrated, mineral-organic fertilizer. Earthworm humus obtained from vermicompost is the best fertilizer, as it contains high concentrations of beneficial bacteria and other microorganisms, many biologically-active stimulants for plants, vitamins, amino acids, fulvic and humic acids, added during the digestive process of the earthworm. Vermicompost is one of the fertilizers accepted in the EU for organic farming. The research has been carried out since 2020 in Matca commune, Galați County and focused on the production of vermicompost and its testing on different crops. The experimental variants scheme contains 7 variants with 3 repetitions: Control, Control treated with Cropmax, solid vermicompost - 2 t/ha applied before transplantation, solid vermicompost - 3 t/ha applied before transplantation, liquid vermicompost applied at foliar level in 3 l/ha dose at 14 days, liquid vermicompost applied at foliar level in 5 l/ha dose at 14 days, solid vermicompost - 3 t/ha applied before transplantation and liquid vermicompost applied at foliar level in a 5 l/ha dose at 14 days. For this experiment, the test plant was tomato. From the estimated results, at a density of 30,000 plants/hectare, it was shown that the highest quantity of tomatoes per hectare was obtained in variant V7 (118.33 t/ha; 116.94 t/ha; 123 t/ha), followed, in second, place by variant V3 (112.71 t/ha; 112.5 t/ha; 113.61 t/ha).
