Abstract: A field experiment was conducted during rabi season of 2014-15 and 2015-16 with an objective to assess the economic feasibility of various treatment combinations. The experiment was laid out in Split plot design with 16 treatment combinations viz. F₁:RDN (120 Kgha^-1), F₂:25% N FYM+75% N through chemical fertilizer, F₃:50% N FYM+50% N through chemical fertilizer, F₄:75% N FYM+25% N through chemical fertilizer under nitrogen management practices in main plot and W₀:Weedy check, W₁:Weed free, W₂:VESTA (Clodinafop 15% + metsulfuron methyl 1%), W₃:TOTAL (Sulfosulfuron 75% + metsulfuron methyl 5%) under weed management treatments in sub plot with three replications. Results revealed that the treatment F₁:100% RDF was found significantly superior over rest of the treatments in all aspects of yield and yield attributes. The length of spike and test weight (1000-grain weight) was found non-significant. No. of grains spike^-1, maximum grain & straw yield was recorded with F₁ 100% RDF which was significantly superior over rest of the treatments and remained at par with F₂ 25% N-FYM + 75% N through chemical fertilizer under nitrogen management practices while the application of herbicide VESTA 400 g (Clodinafop 15% + metsulfuron methyl 1%) given maximum yield and yield attributing characters remained at par with TOTAL 32 g (Sulfosulfuron 75% + metsulfuron methyl 5%) and found significantly superior over rest of the treatments. The treatment combination F₁W₂:100% RDF along with VESTA 400 g (clodianfop 15% + metsulfuron methyl 1%) was found maximum with respect to net income and B-C ratio over rest of the treatment combinations.
