ABSTRACT
A field experiment was conducted during kharif, 2013-14 at Student Farm, College of Agriculture, Rajendranagar, Hyderabad, Acharya N. G. Ranga Agricultural University to find out the effect of different weed management practices in sunflower. Weed spectrum of the experimental field consisted of three groups of weeds like grasses, sedges and broad leaved weeds. The highest seed yield and stalk yields were recorded with weed free conditions and it was on par with practicing hand weeding twice at 20 and 40 DAS, application of oxyfluorfen @ 150 g a.i ha-1 as PE with one hand weeding at 25 DAS. Higher net returns (₹ 35826 ha-1) were realized due to application of oxyfluorfen @ 150 g a.i ha-1 as PE with hand weeding at 25 DAS followed by hand weeding at 20 and 40 DAS (₹ 34434 ha-1). The B: C ratio was higher (2.3) with application of oxyfluorfen @ 150 g a.i ha-1 as PE fb hand weeding at 25 DAS and oxyfluorfen @ 150 g a.i ha-1 as PE fb paraquat @ 600 g a.i ha-1 as PoE at 20 DAS as directed spray over rest of the treatments.
Key words: Sunflower, Oxyfloufen, Pendimethalin, Quizalofop-p-ethyl, Fenoxaprop-p-ethyl, Paraquat, Hand weeding, Net returns.
