Abstract

Weed management is a sustainable approach which promotes the majority of crop production. To control weeds in various cropping systems, farmers employ a variety of techniques, although nowadays, the most popular method is the application of herbicides, which can be attributed to labour shortage. Application and effects of different herbicides against weed flora in wheat crop for sustainable agriculture," was conducted in 2020 and 2021. The experiment's goal was to assess how many herbicides performed against complex weed flora in wheat crop. The experiment was planned and laid out with nine treatments which are pre-emergance application of pendinethalin 1.0 kg a.i. ha-1 at (3 DAS) (T2) and post emergence application of metribuzin 0.3 kg a.i. ha-1 (T1), sulfosulfuron 0.03 kg a.i. ha-1 (T3), metsulfuron-methyl 0.005 kg a.i. ha-1 (T4), clodinafop-propargyl 0.04 kg a.i. ha-1 kg (T5), 2,4-D 0.6 kg a.i. ha-1 (T6), carfentrazone-ethyl 0.025 kg a.i. ha-1 (T7), weed free (T8) and weedy check (T9) and four replications under randomized block design. The major weeds infesting the wheat crop field were Anagallis arvensis, Chenopodium album, Phalaris minor, Parthenium hysterophorus and Cyperus rotundus. The post-emergence application of carfentrazone-ethyl 0.025 kg a i/ha at 33 days after sowing was most efficient in controlling the weeds (both grassy and non-grassy) among the various applied herbicides. Weed growth suppression effect of carfentrazone-ethyl 0.025 resulted significant increase the growth parameters, yield attributes and higher economic yield of wheat over check control in order to promote the sustainability.
