Treatments included four crop establishment techniques (transplanting, puddling and broadcasting sprouted rice seeds, i.e wet-seeding and dry seeding under conventional and zero tillage systems) in rice and two tillage (zero and conventional) and two weed control methods (weedy check and pendimethalin 1.0 kg/ha as pre-emergence+one hand weeding at 30 days after sowing) in succeeding chickpea. Rice field was infested with jungle rice [<i>Echinochloa colona</i> (L.) Link], <i>Caesulia</i> (<i>Caesulia axillaris</i> Roxb.), sessile joyweed [<i>Alternanthera sessilis</i> (L.) DC], and rice flat sedge (<i>Cyperus iria</i> L.) and chickpea with wild oats (<i>Avena ludoviciana</i> Dur.) and toothed burclover (<i>Medicago hispida</i> Gaertn.). Results revealed that methods of rice establishment did influence the weed dynamics in rice-chickpea system. Mean yield of zero-till direct-seeded rice (3 262 kg/ha) was as good as that of puddle broadcast rice (3 343 kg/ha) and better than the transplanted rice (3 038 kg/ha). Effective weed control in preceding chickpea benefitted the succeeding rice crop. Methods of rice establishment and tillage did not influence the chickpea yield. Infestation of weeds caused 78.45% reduction in yield of chickpea. Maximum seed yield of chickpea (2 813 kg/ha) was noticed in pendimethalin followed by one HW under conventional tillage. Zero till direct-seeded rice followed by zero-till chickpea system was the best combination for maximizing system productivity, profitability and energy efficiency. 收起
