This study was conducted in Pokhara, Kaski, Nepal 2023 to investigate the effects of different pinching types and okra varieties on various growth yield parameters. Treatments were arranged under a two-factor Randomized Complete Block Design (RCBD) with three replications. The treatments includes two (Arka Anamika Parbati) 4 (apical bud (P1), ABP along 1 leaf (P2), 2 (P3) control (P4)). Parbati has exhibited higher plant height (80.78 cm) than Arka (72.35 cm). Similarly, P4 type resulted...
