A field experiment was conducted during winter season to find out the effect of herbicides on weed dynamics and yield performance of wheat (Triticum aestivum L.) variety LOK-1 in randomized complete block design with three replications under eucalyptus based agroforestry system. An experiment was conducted at the farmer field village- Majitha, District- Jabalpur during the rabi season of 2016-17 and 2017-18. The field was infested with 5 major weed species Phalaris minor, Rumex dentatus (L.), Melilotus indicus (L.), Chenopodium album (L.) and Launaea nudicaulis (L.) during both the year. The hand weeding showed minimum total weed density and dry weight and proved more effective than all weed control treatments and over weedy check. Among chemical weed control treatment 2, 4-D 0.5 lit ha-1 + hand weeding 30 DAS and 2, 4-D 0.5 lit ha-1 fb metribuzin 0.250 Kg ha-1, Metribuzin 0.250 Kg ha-1 have control both broad leaf and grassy weed and Clodinafop-propargyl 0.140 kg ha-1 control grassy weed over weedy check. The application of 2, 4-D 0.5 lit ha-1 fb metribuzin 0.250 Kg ha-1 (T5: 77.03 and 80.41%), 2, 4-D 0.5 lit ha-1 (T1: 75.15 and 83.00%), and 2, 4-D 0.5 lit ha-1 + hand weeding 30 DAS (T8: 75.18 and 77.60%) was found higher weed control efficiency during both the year under wheat- Eucalyptus tereticornis based agroforestry system. The hand weeding showed maximum weed control efficiency (T9: 86.73 and 95.51%) and proved superior over herbicidal treatments. The higher grain yield and straw yield was found under hand weeding 30 DAS (T9; 19.75, 18.20 and 46.54, 39.72 q ha-1) during both the year.
