Abstract:
A field experiment was conducted during 2020-21 to 2021-22 at CRC, Chirodi, Sardar Vallabhbhai Patel University of Agriculture and Technology Modipuram Meerut (U.P.). The experiment was laid out in split plot design (SPD) to evaluate the effect of four residue management practices in main plots viz. R₁ (Residue Burning), R₂ (Residue Removal), R₃ (Residue treated with PUSA Decomposer) R₄ (Residue treated with Trichoderma) and five weed management option under sub plots; W₁(Weedy) W₂ (Two hand weeding’s @ 30 & 45 DAS) W₃ (Sulfosulfuron @ 25 g a.i. ha^-1) W₄ (Fenoxaprop-p-ethyl + Metsulfuron methyl @ 100 g + 4g a.i. ha^-1) W₅ (Brown manuring fb Chlodinofop @ 60 g a.i. ha^-1) on weed dynamics at 60 and 90 DAS of late sown wheat (Triticum aestivum L.) during rabi season. Out of rice residue management, weed suppress with treatment of residue treated with PUSA Decomposer compare to residue removal during both the year. Among the herbicides, brown manuring fb Chlodinofop @ 60 g a.i. ha^-1 reduces the narrow and broad leaves weeds very effectively and recorded lowest value of population and dry matter of weeds compare to other herbicide treatments at 60 and 90 DAS during both years. Result shows that the application of rice residue treated with PUSA decomposer along with brown manuring fb Chlodinofop @ 60 g a.i. ha^-1 effectively suppresses the total weed flora in wheat crop.
