The experiment was carried out at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during September 2016 to December 2016 to find out the growth, yield and economic benefit of cabbage as influenced by nutrients and leaf plucking. The research comprises of two factors: Factor A: NPK nutrients (four levels) as- N₀ = control, N₁ = N₁₂₀P₃₀ K₁₀₀kg ha^-1, N₂ = N₁₄₀P ₄₀ K₁₂₀kg ha^-1, N₃ = N₁₆₀P₅₀ K₁₄₀kg ha^-1and Factor B: leaf plucking (three levels) as- L₀ = No leaf plucked, L₁ = 4-leaves plucked and L₂ = 6-leaves plucked. The experiment was set up in randomized complete block design (RCBD) with three replications. In case of nutrients, the highest gross yield (90.53 t ha^-1) and marketable yield (68.95 t ha^-1) were obtained from N₃, while the lowest gross yield (60.26 t ha^-1) and marketable yield (44.24 t ha^-1) from N₀. For dissimilar levels of leaf plucking, the highest gross yield (80.64 t ha^-1) and marketable yield (62.08 t ha^-1) were recorded from L₁, whereas the lowest gross yield (74.13 t ha^-1) and marketable yield (56.96 t ha^-1) from L₀. Due to combined effect, the highest gross yield (94.38 t ha^-1) and marketable yield (71.91 t ha^-1) were recorded from N₃L₁, whereas the lowest gross yield (58.75 t ha^-1) and marketable yield (41.15 t ha­^-1) from N₀L₀. From the economic point of view, the highest benefit cost ratio (BCR) was2.35 noted from N₃L₁ and the lowest (1.63) from N₀L₀. It is evident that the N₃L₁ gave the best performance for the growth, yield and economic benefit of cabbage. So, N₁₄₀ P ₅₀ K₁₂₀kg ha^-1 with 4-leaves plucked may be considered as an optimum dose for cabbage production.
