Abstract:

Toothed dock (Rumex denticulate L) is a problematic weed found in wheat crop. The study was conducted to investigate the competitive effects of Rumex dentatus sown at varying densities in association with wheat (Triticum aestivum L.) under field conditions. The experiment was conducted at Kanpur during Rabi 2017-18 and 2018-19 to study the effect of irrigation regimes and weed management on R. denticulate in wheat under split-plot design with four replication having four irrigation regimes and eight factors of weed management. Application of two irrigations at CRI and active tillering stage (I1) significantly reduces the density of R. denticulate and their fresh and dry weight with highest weed control efficiency (WCE) over irrigation at CRI+ jointing+ booting+ flowering+ milking stage (I4), irrigation at CRI + active tillering + booting + flowering stage (I3) and irrigation at CRI + jointing + booting (I2), respectively. Among herbicidal treatments, lowest density, fresh and dry weight of R. denticulate and the highest WCE was recorded with the post-emergence application of broadway (carfentrazone ethyl 20% + sulfosulfuron 25%WG) @ 100 g/ha at 35 DAS as compared to other treatments. However, none of the herbicidal treatments as effective as hand at 20 and 40 DAS.
