Abstract:
The field experiment was carried out during kharif 2021 at Experimental Farm of Agronomy Section, College of Agriculture, Latur to study “Integrated weed management in soybean (Glycine max L. Merrill)”. The soil was clayey in texture and slightly alkaline in (pH 7.8) nature. The experiment was laid out in randomized block design with three replications and nine treatments. The treatments are T1– Weedy check, T2 –Weed free, T3– Soybean + Green gram (2:1) intercropping, T4 – Diclosulam 84% WDG PE 26g/ha +1 Hoeing + Straw mulching, T5– Diclosulam 84% WDG PE 26g/ha + POE Imazethapyr 10% SL @ 0.10 kg/ha at 20-25 DAS, T6 –Imazethapyr 10% SL @ 0.10 kg/ha POE at 20-25 DAS +1 Hoeing at 25 DAS + Straw mulching, T7 – Imazethapyr 10% SL @ 0.10 kg/ha POE + Quizalofop ethyl 5%EC @ 0.075 kg a.i/ha POE at 20-25 DAS (Tank Mix), T8 – Pendimethalin 38.7% CS @ 0.75 kg a.i/ha + Imazethapyr 10% SL @ 0.10 kg/ha POE at 20-25 DAS, T9– Pendimethalin 38.7% CS @ 1.0 kg a.i/ha + 1 Hoeing +Straw mulching. The experimental unit was gross and net plot size divided into 5.4 m x 4.5 m and 4.5 m x 3.9 m respectively. The result showed that weed free (T2) recorded significantly higher growth yield contributing characters followed by application of Pendimethalin 38.7% CS @ 0.75 kg a.i/ha + Imazethapyr 10% SL @ 0.10 kg/ha POE at 20-25 DAS (T8) and Diclosulam 84% WDG PE 26g/ha + POE Imazethapyr 10% SL @ 0.10 kg/ha at 20-25 DAS (T5) respectively were found beneficial in comparisons with the other treatments.
