Berseem, Integrated weed managment, Seed yield, Weed dry weight, Weed intensity

Weed-free check treatment recorded significantly lowest total weed count/m2 and its dry weight at harvest      followed by oxyflourfen pre-emergence 0.10 kg/ha  fb imazethapyr post-emergence 0.10 kg/ha (immediate after harvest of Ist cut) and one hoeing at 3 week after sowing and one hand weeding at 5 week after sowing which were at par with each other. The weed control efficiency was highest in weed free check and significantly superior to all the treatments. Significantly minimum weed index of berseem, green forage yield and seed yield were  observed in treatment oxyflourfen  pre-emergence 0.10 kg/ha  fb imazethapyr post-emergence 0.10 kg/ha and it was at par with treatment one hoeing at 3 week after sowing and one hand weeding at 5 week after sowing and imazethapyr post-emergence 0.10 kg/ha. The economic studies indicatesed that oxyflourfen pre- emergence 0.10 kg/ha fb as post-emergence imazethapyr 0.10 kg/ha immediate after harvest of Ist cut was most cost effective and remunerative. The maximum net monitory returns of  Rs. 64,658/- with B:C ratio of 2.01 was fetched by the treatment oxyflourfen pre-emergence 0.10 kg/ha followed by imazethapyr as a post- emergence application 0.10 kg/ha immediate after harvest of Ist cut was found effective and remunerative followed by treatment  one hoeing at 3 week after sowing and one hand weeding at 5 week after sowing.
