Effect of weed management practices on growth and yield of maize (Zea mays L.)


E Balaji, R Raman, R Krishnamoorthy, K Dhanasekaran

During the Kharif season of 2021, a field experiment was undertaken at a farmer's field in Kurmalur village (Perambalur) to assess the effects of various weed control strategies on maize (Zea mays L.) growth and productivity. The study was carried out in randomised block design with ten treatments and three replications. Among the treatments tested, hand weeding on 15 and 30 DAS recorded the highest weed control efficiency on 30 and 45 DAS (86.7 and 93.7) with low weed density (21.7 and 12.1) on 30 and 45 DAS. Pre-emergence treatment of atrazine followed by post-emergence application of tembotrine had the greatest weed control effectiveness (85.5 and 93.2) on 30 and 45 DAS with low weed density values among the herbicides studied (23.6 and 13.0). Hand weeding twice on 15 and 30 DAS produced the maximum dry matter production at harvest (8934 kg ha-1), number of grains cob-1 (239) and grain yield (4482 kg ha-1) which was comparable to pre-emergence atrazine followed by post-emergence tembotrine treatment.
