A field experiment was conducted during kharif season of 2010 to study the comparative performance of different weed management practices in rice under system of rice intensification (SRI) at Anand Agricultural University, Nawagam (Gujarat). Maximum grain yield, straw yield, yield attributing characters, higher net realization and the lowest weed population under SRI were recorded with weed free treatment (three hand weeding at 15, 30 and 45 days after transplanting-DAT). While, under labour crises situations, post-emergence application of pyrazosulfuron @ 25 g ha−1 in 500 litre water at 10–12 DAT or pre-emergence application of butachlor @ 1.5 kg ha−1 in 500 litre water at 5 DAT integrated with one hand weeding at 30 DAT was found productive and economic under middle Gujarat condition.
