A field experiment was conducted during rabi of 2020-21 at Experimental Farm, Agronomy section, Oilseeds Research Station, Latur to study the “Integrated weed management in rabi sunflower (Helianthus annuus L.)”. The soil was clavey in texture, neutral in nature (7.02 pH), low in organic carbon (0.30 %), very low in available nitrogen (231 kg ha-1), low in phosphorus (8.57 kg ha-1) and very high in potassium (580 kg ha-1). The highest net monetary returns (₹ 47612 ha-1) and benefit: cost ratio (2.29) was recorded with the application of Quizalofop-ethyl 10 % EC @ 40 g a.i. ha-1at 20 DAS (POE) + one hand weeding at 35 DAS (T7). Among different chemical weed control methods lowest weed index, dry weed weight and higher weed control efficiency were observed with the application of Quizalofop-ethyl 10 % EC @ 40 g a.i. ha-1 at 20 DAS (POE) + one hand weeding at 35 DAS (T7).
