SUMMARY
A field experiment was conducted during winter (rabi) season of 2013-14 at Research Farm of Department of Agronomy, CCS Haryana Agricultural University, Hisar to study the effect of butachlor, pendimethalin, imazethapyr and oxadiargyl on yield, quality and economics of berseem fodder (Trifolium alexandrinum L.). The experiment was laid out in randomized block design using three replications with 15 herbicidal treatments with a weedy check, comprising four herbicides at different rates and time of application viz., butachlor at 1000 and 1500 g/ha, pendimethalin at 750 and 1000 g/ha as PRE, imazethapyr at 50, 75 and 100 g/ha as PPI, PRE and 3 WAS and oxadiargyl at 75 and 100 g/ha as PRE along with unweeded control (weedy check). The treatment where imazethapyr was applied at 100 g/ha as post-emergence (3 WAS) was found significantly superior from other treatments and recorded higher plant height (41.6 cm), number of tillers (161/m2), green fodder and dry matter yield (859.8 and 117.0 q/ha), crude protein content (20.8%), crude protein yield (24.3 q/ha), IVDMD (57.3%), DDM (68.4 q/ha) and
benefit :cost ratio (1.77).
Key words: Berseem, Trifolium alexandrinum L., herbicides, fodder yield, quality
