Abstract

It is important to understand that weeds are unwanted, undesirable plants that absorb nutrients faster and in greater quantities than crops, resulting in the reduction of plant yields even at higher rates of fertilization. As a consequence, it is important that promising weed management approaches are developed to determine how to enhance rice productivity. Keeping in this view the present investigation, the experiment was conducted at Agronomy Research Farm of ANDUA&T, Kumarganj, Ayodhya (U.P.) during Kharif 2021. The experiment was laid out in Randomized Block design with three replications, viz., (Pretilachlor @1000 g ai ha-1 (PE), Pretilachlor @1000 g ai ha-1 (PE) + Bispyribac sodium @ 25g ai ha-1 (PoE), Pretilachlor @1000 g ai ha-1 (PE) + One hand weeding at 35 DAT, Bispyribac sodium @ 25g ai ha-1 (PoE), Bispyribac sodium @ 25g ai ha-1 (early PoE at 25 days) + One hand weeding at 45 DAT, Two Hand Weeding at 20 and 40 DAT, Weed free up to 60 days, Weedy check. Based on the results of the experiment, it was concluded that all the growth parameters and yield attributes were significantly affected by the different treatments used. It is clear from the scrutiny of the yield attribute data revealed that the weed free up to 60 days resulted significantly maximum value of growth, yield attributes and yields followed by two hand weeding at twenty and forty DAT. Among herbicides the Pretilachlor @1000 gram ai ha-1 (PE) + One hand weeding at 35DAT having higher growth, yield attributes and yield with other rest herbicides.

Conclusion

Weed free up to 60 days was most effective to control of all sorts of weeds, growth and yield of transplanted rice followed by Pretilachlor @1000 g ai ha-1 (PE) + One hand weeding at 35 DAT.
