A field experiment was conducted at the Research Farm, ITM University, Gwalior; Madhya Pradesh during the kharif seasons of 2017 under the edaphic and climatic conditions of Gwalior (M.P.). The experiment consisted 8 weed management treatments (Imazethapyr @ 70 g a.i./ha (PoE) at 20 DAS + 1 HW at 40 DAS, Quizalofop @ 50 g a.i./ha (PoE) at 20 DAS + 1 HW at 40 DAS, Fenoxaprop-p-ethyl @ 70 g a.i./ha (PoE) at 20 DAS + 1 HW at 40 DAS, Imazethapyr + Imazamox @ 50 g a.i./ha (PoE) at 20 DAS + 1 HW at 40 DAS, Pendimethalin @ 750 g a.i./ha (PE) + 1 HW at 20 DAS, Hand weeding at 20 DAS + Hoeing at 40 DAS, Weed free and Weedy check). It was laid out in randomized block design with 3 replications. Herbicides were applied by knap sack sprayer fi tted with fl at pan nozzle using 500 litre/ha water. In the plots involving hand weeding treatment, weeds were removed manually at 20, 40, 60 DAS and as necessity as per treatment. All other agronomic practices were adopted as per recommended package of practices. The studied for selected attributes by using 3 plants in randomized manner in the seeding depth. Weed free treatment recorded significantly effective values of weed parameters viz. total dry weight (g/m2) & weed control efficiency (%) and crop parameters viz. growth parameters [plant height (cm), number of branches/plant & dry weight/plant (g)], yield attributes [number of pods/plant, number of seeds/pod & test weight (g], computed parameters [seed yield (kg/ha), stover yield (kg/ha) & harvest index (%)], quality parameters [protein content (%), protein yield (kg/ha), gum content (%) & gum yield (kg/ha)] & economics [gross monetary return (₹/ha), net monetary return (₹/ha) & B:C ratio (₹/ha)] over rest of the treatments. The next effective was Hand weeding at 20 DAS + Hoeing at 40 DAS; which was at par with Imazethapyr + Imazamox @ 50 ga.i./ha at 20 DAS + 1 HW at 40 DAS and Pendimethalin @ 750 g a.i./ha + 1 HW at 20 DAS.
