A field experiment was conducted to evaluate the effect of preceding rice crop herbicide residue on growth and yield of succeeding bhendi crop at the Agricultural College and Research Institute, Madurai during Rabi, 2017. The experiment was laid out for the preceding transplanted rice crop in kharif 2017, which consists of eight treatments with three replications. The residual effect of herbicide applied to rice on the bhendi crop recorded lower weed density throughout the crop growth period lead thicker stem compared to weedy check. There was an appreciable difference in total density and dry weight of weeds in bhendi at 20 and 40 days after sowing among the weed control practices. Rooting depth of the bhendi crop is positively correlated with plant height, root dry weight and root thickness. Significantly higher fresh fruit yield of 3.70, 1.57 and 1.32 times were recorded in plots applied with butachlor at 1.25 kg ha-1 on 3 DAT fb hand weeding on 40 DAT, oxadiargyl loaded in zeolite on 3 DAT (T2), oxadiargyl encapsulated with water soluble polymer on 3 DAT (T4) to previous rice crop, respectively.
