A field experiment was conducted at Agriculture Research Station, Annigeri, University of Agricultural Sciences, Dharwad during Rabi season of 2015-16 to find out the effects of integrated weed management practices on nutrient uptake by weeds and chickpea under rainfed condition. All integrated treatments effectively maximized nutrient uptake by crop and reduced uptake of nutrients by weeds. Results revealed that as expected weed check (T11) recorded significantly the highest uptake of nutrients (NPK) by weeds, but treatments T10 (application of pendimethalin @ 1.0 kg a.i ha-1 (PE) fb imazethapyr @ 75 g a.i ha-1 at 20 DAS (POE) fb hoeing at 40 DAS), T9 (pendimethalin @ 1.0 kg a.i ha-1 (PE) fb quizalofop-p-ethyl @ 40 g a.i ha-1 at 20 DAS (POE) fb hoeing at 40 DAS) and T2 (pendimethalin @ 1.0 kg a.i ha-1 (PE) + hoeing twice at 20 and 40 DAS) recorded the lower uptake of nutrients by weeds, at 40 DAS and at harvest. Weed free check (T12) recorded significantly highest uptake of nutrients (NPK) by chickpea but was on par with treatments, T10, T9 and T2.
