Online published on 15 October, 2015. Summary A field experiment was conducted at Kota during kharif 2005 to findout an effective integrated weed management practice in soybean (Glycine max L.). Two hand weeding at 20 and 40 DAS significantly reduced weed density and its dry weight at 30 and 60 DAS and also maximized number of branches plant−1 (9.33), seeds pod−1 (3.33), seeds index (11.03 g), seed yield (2278 kg ha−1) and straw yield (2975 kg ha−1) over sole application of clomazone ethyle (1.0 kg ha−1) and quizalofop ethyle (50 g ha−1). However, quizalofop ethyl (50 g ha−1) + chlorimuron ethyl (9 g ha−1) as post-emergent significantly reduced weed density, dry weight and recorded higher branches plant−1, seeds pod−1, seed index, grain yield and straw yield compared to sole application of clomazone ethyl and quizalofop ethyl.
