A field experiment was carried out during kharif season of 2001 to 2002 to study the effect of different weed management techniques on weed dynamics and green fodder yield of sorghum. The sorghum crop was infested with Cyperus spp. (38.9%) and Echinochloa colona (28.0%) as major weeds and others (33.1%), which reduced 75.0 and 22.8% of green forage yields during both the years, respectively. Application of atrazine at 0.5 kg/ha PE + 0.5 kg/ha at 10 days after sowing significantly reduced total population and dry weight of weeds being at par to atrazine 1.0 kg/ha PE, one hand weeding at 20 days after sowing and atrazine at 0.5 kg/ha PE+ one hand weeding at 30 days after sowing. These treatments had higher weed control efficiency (WCE) than that of alachlor, pendimethalin, cowpea as intercrop, one and half time seed rate and weedy check during both the years. Application of atrazine at 0.5 kg/ha PE + 0.5 kg/ha at 10 DAS produced more plant height, dry matter accumulation/shoot, leaf area/plant and also green fodder yield of the sorghum, being at par with that of atrazine at 1.0 kg/ha PE, one hand weeding at 20 DAS and atrazine 0.5 kg/ha PE + one hand weeding at 30 DAS but significantly higher than that of other treatments in both the years.
