Abstract
The excessive use of chemical fertilizers poses hazardous environmental effects and compromises food safety. In contrast, organic fertilizer usage has an advantage of being cheap, improving soil properties, and stimulating root development. The effect of filter mud cake (FMC) as an organic fertilizer and Trichoderma viride (TRI) as a biofertilizer, either individually or combined with NPK as a chemical fertilizer (CF) on pea growth, yield, and chemical constituents were evaluated. Field treatments were assigned in a randomized complete block design (RCBD) for two consecutive seasons with three replicates. Our results showed that all treatments resulted in an increase in pea plant growth, yield, and chemical constituents compared to the control. However, the highest improvements were observed with the FMC + TRI + CF75% (reduced chemical fertilizer doses) treatment, in most of the studied parameters, including fresh pod weight, nutrient content (N, P, K), and protein percentage. Additionally, the FMC + CF75% treatment also demonstrated notable increases, particularly in fresh pod weight and phosphorus content. While CF100% (full chemical fertilizer doses) showed good performance in certain parameters, it was less effective overall compared to the combined treatments. Therefore, the combination of FMC, TRI, and CF75% is recommended as the most effective treatment for enhancing pea plant productivity and nutritional value, with the highest economic feasibility.
