Abstract: An experimentrnwas conducted during the rabi seasons of 2010-2011 at BHU, Varanasi, tornevaluate the influence of herbicides on weeds and yield of field pea. Resultrnindicated that application of pendimethalin 1kg ha 1rn(PE) fb imazethapyr 50 g ha 1 (rnat 20 DAS as PoE) recorded significantly the lowest density and dry weight of weed, weedrnindex, and the highest weed control efficiency, growth and yield attributes,rngrain and straw yield over imazethapyr rn50 g ha 1as (PoE), chlorimuron-rnethyl 4 g ha 1 (PPI) and pendimethalin 1.0rnkg ha 1 (PE); and it were at parrnwith pendimethalin 1 kg ha-1 (PE) fb imazethapyr 75 g ha-1 (PoE),rnquizalofop- ethyl 50 g ha-1 (PoE), quizalofop- ethyl 60 g ha-1rn(PoE) and imazethapyr 75 g ha-1 (rnPoE). However, weed free situation showed superiority over herbicidalrntreatments with respect to density and dry weight of weeds; and growth andrnyield of field pea.
