This study was carried out in order to determine the effect of various manganese fertilizers [manganese sulfate (MnSO ₄.3H ₂O) (MS), 27% manganese (Mn) and manganese ethylenediaminetetraacetic acid (Mn-EDTA) (ME), 12% Mn], their doses (0, 6, 9, 12 mg Mn kg ⁻¹ for the soil and 0, 0.2, 0.3, 0.4% for the leaf) on yield and net return of dwarf bean. Field experiments were conducted in the randomized blocks split plot design with four replications under Konya ecological conditions in Turkey. Soil applications were made on bands as a single application at sowing whereas foliar applications (FA) were made at two times. Results of the field experiments showed the highest bean yields were significantly obtained by the fertilizer of ME-FA sprayed (243.80 and 257.74 kg da ⁻¹). For both years, the lowest yields were obtained by the MS-SA applications (166.97 and 180.60 kg da ⁻¹). The maximum net income was US $104.16 da ⁻¹ and US $156.06 da ⁻¹ by years.
