Abstract: Experiment was conducted under All India Coordinated Research Project on Forage Crops to study the Herbicidal response on economical effectiveness of Berseem (Trifolium alexandrinum L) under slight acidic medium land condition of Jharkhand. The field experiment was conducted during three consecutive years from Rabi 2011 -12. The soil of experimental plot slightly acidic with pH 6.4 crop faced narrow leaf, Broad leaf weeds and sedges problem. The different treatment combinations were made with pre-emergence herbicides viz. pendimethalin and oxyflourfen and post-emergence herbicide, viz. imazethapyr in different proportion along with weedy check (control). Results revealed that the pre - emergence application of Pendimethalin @ 0.4 kg a.i/ ha resulted into less weed population (54.66), weed dry weight/m2 (8.89), Green fodder yield (478.97 q/ha), Dry fodder yield (74.96 q/ha), Seed yield (2.48 q/ha), Gross return (1,92,903 Rs/ha), Net return (1,69,191 Rs/ha) with B:C ratio (7.12) over other herbicidal combinations. Further, interms of economics Pendimethalin @ 0.4 kg a.i/ ha produced about 47.36% economicaly more over lowest under Oxyflourfen @ 0.100 kg a.i/ ha + Imazethapyr @ 0.100 kg a.i/ ha (after first cut). The pre emergence application of Pendimethalin @ 0.4 kg a.i/ ha and Pendimethalin @ 0.300 kg a.i/ ha + Imazethapyr @ 0.100 kg a.i/ ha (after first cut) were comparable in terms of efficacy of the herbicides.
