Abstract: A field experiment was conducted at Udaipur during kharif 2016 to study the effect of weed management practices on weed dynamics and yield of maize (Zea mays L.). The experiment was consisted of ten treatments viz., control, weed free, and alone or sequential application of different herbicides which were replicated thrice in randomized block design (RBD).All the weed control treatments resulted significant reduction in density and dry matter of both grassy as well as broad leaf weeds and total weeds at different growth stages in maize crop. The maximum weed control efficiency were found at 30 (90.97 %)and 60 DAS (81.04 %) by applying atrazine 0.75 kg ha-1 +pendimethalin 0.75 kg ha-1 PE mixture. Similarly, minimum weed dry matter accumulation was found with pre- emergence application of atrazine 0.75 kg ha-1 + pendimethalin 0.75 kg ha-1 at all growth stages of crop. The yield (grain and stover) of maize were increased significantly under weed free over weedy check while among herbicidal weed control treatments, yield (grain and stover) were maximized under the effect of atrazine 0.75 kg ha-1 + pendimethalin0.75 kg ha-1 PE mixture.
