Aiming to investigate the effect of Rhizobium Leguminosarum inoculum, rice hulls, and urea fertilizer on the availability of phosphorous and potassium regarding the growth and yield traits of broad bean plant (Vicia faba L.), a field trial was carried out during the autumn agricultural season 2021 in Al-Daghara district, 17 km north of the center of Al-Diwaniyah Governorate-Iraq. Two levels of Rhizobium Leguminosarum (R0) the control, and (R1) bacterial inoculation, three levels of organic fertilizer (rice hulls) S0, S3, and S5 t/ha-1, and three levels of urea fertilizer (U0, U50, and U75) kg/ha-1 and their overlap, were used and studied. The results of the interaction treatment (bacterial inoculum + rice hulls (5 t/ha-1) + urea fertilizer (75 t/ha-1)) yielded the highest significant increase in the traits of root-knot number, root-knot weight, potassium concentration, phosphorous concentration) compared to the control, 23,851 knots/ plant, 0.550 / 122.6 kg.soil-1 and 23.812 kg/soil-1, respectively.
