Influence of integrated weed management on growth, productivity and economics of wheat (Triticum aestivum L.)

A field experiment was conducted at College of Agriculture, Loni Farm during 2015 and 2016 on silty clay loam soil with 7.4 pH. The climatic conditions during experimental period were favourable. The experiment was laid out in randomized block design with three replications. The treatments consisted of combination of cultural treatments, pre-and postemergence herbicides as well as unweed check. The results showed that the growth parameters, yield attributes, seed yield and straw yield were increased significantly by treatment 3 HW at 20, 40 and 60 DAS which was at par with treatments pendimethalin @ 750 g a. i./ha as preemergence fb hoeing at 30 DAS, metsulfuron methyl @ 5 g a. i./ha POE at 20 DAS fb hoeing at 30 DAS, metribuzin @ 200 g a. i./ha POE at 20 DAS fb hoeing at 30 DAS and 2, 4-D @ 500 g a. e./ha POE at 20 DAS fb hoeing at 30 DAS which was followed by treatment metsulfuron methyl @ 5 g a. i./ha POE at 20 DAS and metribuzin @ 200 g a. i./ha POE at 20 DAS. The B: C ratio and net returns were found significantly higher in treatment pendimethalin @ 750 g a. i./ha as pre-emergence fb hoeing at 30 DAS. Minimum growth parameters, yield attributes, yield and economics were noticed in treatment unweeded control.
