This study investigates the impact of various soil management practices and fertilization treatments on the growth, yield and quality of 'DarianaBac'sweet pepper (Capsicum annuum L.) cultivated in polyethylene greenhouses. Experimental variants were defined by two distinct soil preparation methods: plowed soil and rotary-tilled soil, coupled with five different fertilization treatments, including Albit + Turboroot, Biochar + Woodvinegar + Cropmax, Nutriplant + Resid, Orgevit + Kerafol and untreated controls. Comprehensive assessments were conducted across several key parameters: plant biometrics (plant height, number of branches, stem collar diameter, flower count per plant), physiological and stress-related responses (anthocyanin and chlorophyll content), productive parameters (fruit count per plant, average fruit weight, yield per plant), fruit morphology (fruit width, length, and form index) and yield quality indicators (carotenoid and lycopene content, total soluble solids, and dry matter content of fruits). Statistical analysis revealed significant differences in plant development and yield outcomes influenced by both soil treatment and fertilization regime.
