Field experiments were carried out during summer seasons of 2017 and 2018 to study the effect of preceding (Rice-Okra) crops herbicide residue on weed, growth, yield and economics of succeeding blackgram. Residual effect of butachlor at 1.25 kg/ha on 3 days after transplanting (DAT) fb hand weeding (HW) on 40 DAT imposed in the first season rice crop and followed by hand weeding (HW) twice at 20 and 40 days after sowing (DAS) (T6) in okra and blackgram significantly influenced the reduction of weed dry weight accumulation by 8.75 and 7.44 times in mainland and island ecosystem, respectively at 20 DAS. The same treatment recorded the highest weed control efficiency (WCE) of 88.6, 86.5 and 86.2, 80.7 % observed at 20 and 40 DAS under mainland and island ecosystem, respectively. Among, the weed control treatments, residual effect of butachlor at 1.25 kg/ha on 3 DAT fb HW on 40 DAT to rice and HW twice at 20 and 40 DAS (T6) to okra and blackgram has recorded 64.8 and 65.0% higher seed yield of blackgram under main and island ecosystem, respectively.

“…It might be due to weeds were adapted to wide range of environmental condition and also deplete natural resources for their growth. Similar species of weeds were also reported by Bommayasamy et al (2018). Herbicide residual effect of weeds Herbicide residual effect of preceding rice crops weed control treatments exerted significant influence on grasses, sedges and broad leaf weed population and dry biomass production on 20 DAS (Table 2).…”

Field experiment was conducted at Field Crops Research unit, ICAR- Central Island Research Institute, Bloomsdale, Port Blair during summer season, 2018. To study the preceding rice herbicide residual effect in control of weeds, growth and yield of urdbean in rice-bhendi-urdbean sequence under high rainfall area. At 20 DAS, grassy weeds (48.00 weeds/m2) were predominant species of weeds followed by sedges and broad leaf weeds of 29.67 and 22.67 nos./m2 respectively. Among the irrespective of weed control treatments, at 20 DAS, residual effect of 1.25 kg/ha butachlor at 3 DAP + manual weeding at 40 DAP in rice + two manual weeding on 20 and 40 DAS in both bhendi and urdbean recorded significantly lower grass, sedges, broad leaf weeds population and weed biomass of 11.67, 8.67, 6.67 weeds/m2 and 2.93, 2.02, 1.84 g/m2 respectively. Residual effect of 1.25 kg/ha butachlor applied at 3 DAP along with manual weeding at 40 DAP in rice + two manual weeding on 20 and 40 DAS in both bhendi and urdbean obtained 299 kg/ha higher seed yield as compared to weedy control.
