Abstract:
A field experiment was conducted at the Seed Cell Unit (F Block), Mahatma Phule Krishi Vidyapeeth, Rahuri, during Kharif season of 2021-2022. The experiment was laid out in randomized block design (RBD) with three replications and nine treatments viz. T₁: Pendimethalin 30% EC @ 1000 g ha^-1 (PE), T₂: Pendimethalin 30% EC @ 1000 g ha^-1 ( PE) + 1 hoeing at 20 DAS, T₃: Imazethapyr 10% SL @ 100 g ha^-1 at 20 DAS, T₄: Propaquizafop 2.5% + Imazethapyr 3.75% w/w ME @ 50 + 75 g ha^-1 at 20 DAS, T₅: Diclosulam 84% WDG @ 25 g ha^-1 (PE), T₆: Diclosulam 84% WDG @ 25 g ha^-1 (PE) + 1 hoeing at 20 DAS, T₇: Imazethapyr 35% + Imazamox 35% WG 70 g ha^-1 + MSO Adjuvant @ 2 ml/l of water at 20 DAS, T₈: Weed free and T₉: Weedy Check. The results revealed that, minimum and significantly lower NPK uptake by weeds were observed with treatment T₈ weedy free. The nutrient uptake by soyabean was significantly higher in treatment T₈ weed free. The respective values of uptake of NPK by the weeds was 150.82, 27.66 and 67.82 kg ha^-1, respectively.
