Abstract:

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 find out suitable herbicides for productivity enhancement by suppression of associated weeds in berseem (Trifolium alexandrinum L.). Fifteen herbicide combinations namely 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 were evaluated and compared along with unweeded control (weedy check) and these herbicide combinations along with weedy check were tested in Randomized Block Design with three replications. The observations were recorded on weed density (No./m2), total weed density (No./m2), dry matter accumulation by weeds (g/m2), weed control efficiency (%), visual phyto-toxicity (%) and total green fodder yield (t/ha). Among herbicides, imazethapyr at 100 g/ha at 3 WAS (also imazethapyr at 75 g/ha at 3 WAS found second best treatment for yield (85 t/ha) and weed control efficiency (67.7-75.8)) and butachlor 1500 g/ha as pre-emergence were significantly superior in controlling weed flora (weed control efficiency 69.7-77.3 and 68.7-75.8%) and recorded higher green fodder yield (86.0 and 82.1 t/ha) in berseem  than other treatments.
