e0“The greatest shoot dry weight of purple nutsedge during the growing season was observed in direct seeding method and high levels of nitrogen. The maximum amount of this trait at eight and ten weeks after planting was achieved in the level of 100 kg N ha-1 which was about 3.797 and 7.306 gr plant-1, respectively.”
e1“In order to evaluate the growth characteristics of purple nutsedge under the conditions of interference with onion, a factorial experiment”

- Intervention effect At eight weeks, onion set planting gave minimum weed underground dry weight of 0.888 gr plant-1.
- Intervention effect At ten weeks, onion set planting gave minimum weed underground dry weight of 1.873 gr plant-1.
- Association Higher nitrogen levels stimulated purple nutsedge growth.
- Recommendation The authors recommend onion set planting with 100 kg N ha-1 to manage nutsedge.
