A field experiment on “Effect of integrated weed management on growth, yield and quality of soybean (Glycine max L Merrill)” was undertaken during kharif, 2013-14 at Post Graduate Institute Instructional Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra). The various growth contributing characters viz., plant height, plant spread, number of leaves, leaf area, number of root nodules and dry matter production were significantly higher with treatment weed free i.e., one hoeing at 15 DAS and 2 HW at 25 and 45 DAS, which was at par with PE application of pendimethalin 38.7 per cent cs @ 677.25 g a.i. ha-1fb 1 HW at 30 DAS, PE application of metribuzin @ 525 g a.i. ha-1fb 1 HW at 30 DAS and metribuzin @ 525 g a.i. ha-1fb imazethapyr + propaquizafop-ethyl @ (80+60) g a.i. ha-1 The yield contributing characters like number of pods plant-1,number of seed plant-1,weight of,pod weight plant-1, weight of seeds plant-1 were recorded significantly higher with treatment weed free i.e., one hoeing at 15 DAS and 2 HW at 25 and 45 DAS, which was at par with PE application of pendimethalin 38.7 per cent cs @ 677.25 g a.i. ha-1 fb 1 HW at 30 DAS, PE application of metribuzin @ 525 g a.i. ha-1 fb 1 HW at 30 DAS, and metribuzin @ 525 g a.i. ha-1fb (imazethapyr + propaquizafop-ethyl) @ (80+60) g a.i. ha-1 and same pattern also observed in seed and stover yield. All the weed control treatments controlled weeds effectively as compared to unweeded check. Among the weed management treatments One hoeing at 15 days after sowing followed by hand weeding at 25 and 45 days after sowing, metribuzin @ 525 g a.i. ha-1 combined with one hand weeding at 30 days and metribuzin @ 525 g a.i. ha-1fb imazethapyr + propaquizafop-ethyl @ (80+60) g a.i. ha-1 after sowing recorded significantly higher values of weed control efficiency, herbicide efficiency index and minimum values of weed index indicating better bio-efficacy of treatments.
