A field experiment was carried out for two consecutive years in rabi seasons of 2017-18 and 2018-19 at Research Cum Instructional Farm, IGKV, Lt. Dr. Ramchanra Singh Dev College of Agriculture and Research Station, Baikunthpur, Korea, Chhattisgarh. The soil of experimental field was (Vertisols), neutral in reaction, low in available nitrogen, medium in available phosphorus and high in available potassium. The experiment was laid out in Split Plot Design with three replications. The main plot treatment consisted of 03 Irrigation levels I₁: 0.8 IW/ CPE, I₂: 1.0 IW/ CPE, I₃: 1.2 IW/ CPE and Sub-plot treatment consisted of 06 Weed management i.e. W₁: Sulfosulfuran (20 g ha^-1), W₂: Clodinofop (60 g ha^-1), W₃: Metsufuron (4 g ha^-1), W₄: Clodinofop + Metsulfuran (60 g + 4 g ha^-1), W₅: Sulfosulfuran + Metsulfuran (20 g + 4 g ha^-1), W₆: Unweeded Control. The finding revealed that the irrigation in wheat at I₃: 1.2 IW/CPE recorded significantly highest yield attributes and grain and straw yields and harvest index were also found significantly highest under this treatment. As regards to weed management practices in wheat, treatment W₄: Clodinofop + metsulfuron (60 g+4 g ha^-1) registered significantly highest yield attributes and grain and straw yields and harvest index as compared to others. Interaction between I₃: 1.2 IW/CPE ratio and W₄: Clodinofop + Metsulfuran (60 g + 4 g ha^-1) registered significantly highest number of tillers m^-2, dry matter accumulation plant^-1 grain and straw yields and harvest index.
