Effect of Weed Interference on Growth of Maize (Zea mays L.) in Shambat, Bahri Locality, Khartoum State, Sudan

Abstract

The experiment was conducted in College of Agricultural Studies, Shambat, Sudan University of Science & Technology, Khartoum State during the summer season of 2017 to determine the effect of weed interference on maize growth parameters. Results of this investigation showed that maize growth parameters which includes plant height (cm), number of leaves/plant, shoot fresh weight (g)/plant and shoot dry weight (g)/plant reduced when the duration of weed infested period increased and increased when the duration of weed infested period decreased. From the results of these studies it can be concluded that, keeping the crop long weed-free duration is enough to provide high growth parameters. Although maize growth parameters was increased in all weed free durations, these increases were positively related with prolonged weed free durations. The highest growth parameters was provided from treatments in which weeds were left for the shortest periods from emergence.
