Abstract:
A research experiment was conducted during Rabi 2017-18 and 2018-19 at Kanpur to study the effect of irrigation, pre and post-emergence herbicides on Chenopodium album in wheat under split-plot design with four replication having four irrigation schedule and eight factors of weed management. Results revealed that application of two irrigations at CRI and active tillering stage (I1) significantly reduces the density of C. album and their fresh and dry weight with highest weed control efficiency (WCE) irrigation at CRI+ jointing+ booting+ flowering+ milking stage (I4) and irrigation at CRI + active tillering + booting + flowering stage (I3) and it was statistically at par with irrigation at CRI + jointing + booting (I2). Among weed management practices, significantly the lowest density, fresh and dry weight of C. album and the highest WCE was recorded with the post-emergence application of broadway (carfentrazone ethyl 20% + sulfosulfuron 25%WG) @ 100 g a.i. ha-1 at 35 DAS as compared to other treatments. None of the weed management treatments as effective as hand at 20 and 40 DAS.
