Abstract

A field experiment was conducted to response of chickpea cultivars (GG-2, BGD-72, Dahod yellow) to weed management practices under south Gujarat conditions during Rabi season of 2011-2012 at Navsari Agricultural University, Navsari, revealed that lowest weed population, lowest dry weight of weed (10.14 kg/ha -1 ), higher seed (1804 kg ha -1 ) and stover (2782 kg ha -1 ) yields were secured under treatment of weed free upto harvest (H.W. at 20, 40 and 60 DAS ) followed by treatment of pendimethalin @ 0.75 kg ha -1 with one hand weeding at 45 days after sowing. All the varieties found equally suitable with similar yield potential and competitive with weeds for cultivation under South Gujarat conditions.
