Improving Plant Growth, Seed Yield, and Quality of Faba Bean by Integration of Bio-Fertilizers with Biogas Digestate

Exploring environmentally eco-friendly approaches to enhance crop growth and productivity are essential for sustainable agriculture. Therefore, a field trial was conducted during two growing seasons study the effects of synthetic (nitrogen, N; phosphorus, P; potassium, K), biogas digestate (BioD), bio-fertilizer (BioF), their combinations on growth, yield, seed quality faba bean (Vicia L.). The number treatments seven, as follows: control (zero NPK), NPK (30 kg N ha−1; 45 P2O5 ha−1: 48 K2O ha−1) recommended dose, BioD (2 t ha−1), BioF (plant growth-promoting rhizobacteria; 1 50% + BioD, BioF, BioF. results indicated that all fertilizer sources improved bean. However, highest increase in plant height, leaf area, dry weight, stem weight recorded combined application Moreover, +BioF fertilization enhanced branches, seeds, 100 yield Similarly, total chlorophyll N, P, K contents leaves. also increased traits such protein, carbohydrate contents. outcomes parameters suggest concurrent with can reduce fertilizers.
