Economics, Fenoxaprop-p-ethyl, Late sown wheat, Nitrogen uptake, Weeds, Yield

An experiment was conducted during Rabi season of 2010-11 at Agronomy Research Farm of NDUAT, Faizabad to assess the influence of   fenoxaprop-p-ethyl at various doses with its standard check and clodinofop on weeds, plant growth, nitrogen uptake and production of late sown wheat. All weed control treatments at different doses effectively reduced nitrogen removal by weeds and its ranges in between 2.01 to 4.62 kg/ha. Post- emergence application of fenoxaprop (Whipsuper) standard check 120 g,  fenoxaprop-p-ethyl at 100 and 120 g and Topic (clodinofop) 60 g/ha (standard check) produced significantly higher yield under delayed sown wheat.
