Abstract

The present investigation was carried at Research Farm of R.A.K. College of Agriculture, Sehore (Madhya Pradesh), during kharif 2016. Major objective of the investigation was to evaluate effect of weed management practices on associated weed flora in soybean + pigeonpea intercropping system. A very limited work on weed management in soybean + pigeon pea intercropping has been done as an application of herbicide. Six weed control practices were evaluated in randomized block design with three replications. The results of present study revealed that hand weeding twice at 30 and 45 DAS recorded least weed index and highest weed control efficiency followed by application of imazethapyr 35% + imazemox 35% 70 WG 70 g/ha at 20 DAS (PoE) and pendimethalin 30 EC 1 kg/ha (PE) fb imazethapyr 10 SL 100 g/ha (PoE). Present study helped in finding suitable weed control practices in soybean + pigeonpea intercropping system.

Conclusion

Based on the foregoing discussion, it can be concluded that among weed management practices hand weeding twice at 30 and 45 DAS recorded least weed index and highest weed control efficiency followed by application of imazethapyr 35% + imazemox 35% 70 WG 70 g/ha at 20 DAS (PoE) and pendimethalin 30 EC 1 kg/ha (PE) fb imazethapyr 10 SL 100 g/ha (PoE).
