Effect of Spraying with Nano Potassium on the Growth and Yield of Two Cultivars of Bean (Vicia faba L.)

Abstract The research was carried out during the growing season 2021-2022 to find response of two cultivars (Vicia faba L.): Luz De Otono (C1) and symbolized for them by symbols (C2,C1) spraying potassium nano fertilizer (0, 1.2 g/L) symbolizing with (T3.T2,T1), respectively. experiment according a randomized complete block design (R.C.B.D.), studied characteristics leaf area, plant height, chlorophyll pigment content as well dry weight bio yield seeds their protein content., characters reached in area (52.94 dcm 2 ), (23.99 SPAD) (4.089 tan h -1 results showed that interaction C2T3 significantly superior height (68.57 cm), per (56.57 dm ).
