Abstract: The improvement of agriculture productivity is depending on many factors including high-quality seeds and fertilizers. Soil fertility and water holding capacity may affect plant growth which decreases production. This research aims to provide information on three different fertilizers used in the agriculture production system such as Yard Manure (Organic), Urea, DAP, and their combination on vegetative growth and productivity of bush beans RWR2245. Fertilizers were applied in each plot equally through Randomised Complete Block Design (RCBD). The plot without fertilizer had shown the highest germination percentage (T0) of 88.5%, while the plot T5(Urea + FYM) had shown the lowest germination percentage of 43.5%. Plant vigor parameters were evaluated at 20, 30, and 40 days after sowing. T4(FYD + DAP) showed the highest growth rate and T0 (without fertilizer) had the lowest growth rate. By considering the diameter, T4 (4.875mm) had the highest stem diameter, whereas T0 (3.025mm) had a lower stem diameter. The maximum number of leaves obtained in T4 was 18.00, while the minimum number was 11.75 observed in treatment without fertilizer To (control). The productivity parameters such as the day at 50% flowering after planting, the plant pod number, seeds number in pod per plant, the weight of 1000 bean grains for each treatment, and the total yield in tons per hectare (t/Ha) were observed, and results show that the combination of T4 (FYM + DAP) and T1 (FYM+UREA) applied alone resulted in the highest yield (2.41t/ha) and 2.06 t/ha in average, respectively, while the treatment without fertilizer T0 showed the lowest result of 1.7t/ha. Different fertilizer levels had a significant effect (p
