Environmental pollution and high costs of mineral fertilization have impelled scientists and farmers to use environmentally friendly fertilizers. An experiment was conducted to evaluate the effect of different combinations of rabbit manure (RM), rock phosphate (RH), feldspar (F), and bio-fertilizers [Microbine (Bio-N), Phosphorin (Bio-P) and Potassiumag (Bio-K)] on the growth, yield, and quality of tomato (Lycopersicon esculentum Mill.) plants. The mixture of RM, RH, and F + Bio-N-P-K increased the tomato fruit yield by 30% compared to inorganic fertilization. The application of RM, RH, and F with the bio-fertilizer (Bio-N-P-K) inoculation increased the concentration of N, P, and K in the leaves of tomato by 34%, 35%, and 50% in comparison to the same treatment without the bio-fertilizer. The current study clearly depicted that natural minerals (RH and F) and nitrogen, phosphorus, and potassium bio-fertilization lead to higher yields and better fruit quality than conventional fertilization.
