Weed cover and height, species</p><p>present and herbicide damage were among the variables</p><p>recorded. Soil tillage prior to the crop establishment</p><p>promoted weed germination from the seed bank. A total of</p><p>31 weed species were recorded from a 3452 m<span>2 </span>experimental</p><p>area during the first 14 months after sowing. An interaction</p><p>between sowing distance and weed management strategies</p><p>was determined for gramineus and broadleaf species.</p><p>Paspalum fasciculatum was the dominant species in plots</p><p>under hand weeding while Ageratum conyzoides prevailed in</p><p>glyphosate treated plots. Nine months after sowing, weed</p><p>height and cover along crop rows or between them were</p><p>different depending on the sowing density. In general,</p><p>chemical weed control was efficient, although care should be</p><p>taken during the first spraying when crop and weed height are</p><p>similar, to avoid crop damage.</p>}, number={1}, journal={Agronomía Mesoamericana}, author={Bogantes-Arias, Antonio and Agüero-Alvarado, Renán}, year={2003}, month={Apr.}, pages={41–49} }
