PREPARATION AND USE OF A NATURAL BIO-PREPARATION THAT INCREASES THE YIELD OF APRICOT (PRUNUS ARMENIACA) AND FIGHTS PESTS (BASED ON BEAN HUSK + CALIFORNIA EARTHWORM HUMUS)

The excessive use of chemical fertilizers and pesticides in modern horticulture has led to environmental degradation, soil fertility decline, and reduced biodiversity. This study investigates the development and application of an eco-friendly bio-preparation derived from bean pods (Phaseolus vulgaris residues) and vermicompost produced by Californian earthworms (Eisenia fetida) to enhance yield and pest resistance in apricot (Prunus armeniaca). The research evaluates the physicochemical properties of the bio-preparation, its impact on plant growth, yield parameters, and resistance against common pests. Results indicate that the combined application significantly improves soil fertility, increases fruit yield, and enhances plant immunity. The proposed bio-preparation demonstrates strong potential as a sustainable alternative to synthetic agrochemicals.
