Abstract

Enhancing the efficacy of biofertilizers and biopesticides for horticultural applications presents numerous challenges, given the need to balance effectiveness with environmental and economic factors. Achieving these goals requires rigorous research into advanced technologies and formulations capable of effectively replacing or complementing traditional chemical inputs, without compromising crop yield or quality. The present study aimed to develop a versatile and yet accessible hybrid percolation–sonication system and method, designed to optimize polyphenol extraction from nettle and sage plants. The resulting extracts were combined and applied on organic tomato crops, to evaluate their biofertilizer and biopesticide effectiveness, in comparison to conventional chemical inputs. Operating the equipment in a hybrid percolation–sonication system led to a 36% increase in polyphenols extraction for nettle and a 29% increase from sage. Regarding the effect on tomatoes, data showed that plants treated with biofertilizer extracts were over 42.88% more productive than control samples and 17.67% more productive than tomatoes treated with chemical fertilizers. Tomato plants treated with biofertilizers grew approximately 10% taller and developed stems that were 5% thicker compared to those treated with chemical fertilizers.
