Abstract: The Present investigation entitled, “Effect of integrated weed management practices on growth, yield and its attributes in okra (Abelmoschus esculentus (L.) Moench) cv. Utkal Gaurav.” was conducted at the field site of AICRP on Vegetable Crops of O.U.A.T, Bhubaneswar, Odisha, India during kharif season 2018-19. The objective of the present investigation was to study the impact of weed management on growth and yield attributing characters of Okra. The experiment was laid out in RBD Design with 7 treatments, replicated thrice. The Seven Treatments Schedules were T₁-weedy check (Control), T₂-weed free check (3 hand weeding), T₃- pre-emergence application of pendimethalin @6 ml L^-1, T₄- Pre-application of pendimethalin @ 6 ml L^-1 + One hand weeding, T₅- Pre application of pendimethalin @ 6 ml L^-1+ quizalofop ethyl 40-50 g ha^-1 at 20 DAS, T6-Post emergence application of metribuzin @ 525g ha^-1 at 20DAS, T₇- Post emerging application paraquate (0.5 kg ha^-1), fluchloralin (1.5 kg ha^-1). Among the different weed management practices, the pre-emergence application of pendimethalin @ 6 ml L^-1 + one hand weeding (T₄) resulted maximum green fruit yield of 113.09 q ha^-1 with maximum B:C ratio of 1.49 excluding fruit yield of 120.49 q ha^-1 under weed free check (T₂). However, these both treatments (T₂ and T₄) were statistically at par in terms of fruit yield per ha. Although, the weed free check (3 hand weeding) (T₂) recorded highest fruit yield but the net return of this treatment is less (B:C ratio 1.19) due to higher cost of cultivation.
