Abstract: A field experiment was carried out during summer season of 2008 on a loamy sand soil at Regional Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, District: Banaskantha (Gujarat) to study the eight weed management practices i.e., Unweeded control (W₀), Weed free (i.e., Hand Weeding at 20, 40 and 60 DAS) (W₁), Hand weeding at 20 and 40 DAS (W₂), Interculturing at 20 and 40 DAS (W₃), Pre-emergence application of Pendimethalin @ 1.0 kg a.i./ha (Blanket application) (W₄), W₄ + Interculturing at 20 DAS (W₅), W₄ + Interculturing at 40 DAS (W₆) and W₄ + Hand Weeding at 40 DAS (W₇) along with two fertility levels i.e., 75 % recommended dose of NPK (i.e., 112.5 - 37.5 - 37.5 NPK kg/ha) (F₁) and 100 % recommended dose of NPK (i.e., 150 – 50 - 50 NPK kg/ha) (F₂) on okra [Abelmoschus esculentus (L.) Moench.] crop. Results shows that finally weed free treatments W₁ (H.W. at 20, 40 and 60 DAS) recorded the highest number of nodes per main stem and it was at par with treatments W₂ (H.W. at 20 and 40 DAS) and W₇ (W₄ + H.W. at 40 DAS). Numbers of fruits per plant and fruit yield per plant were also significantly highest with weed free treatment. Treatment combination of W₀F₂ recorded the highest dry weight of weeds (252.54 g/m²).
