Competition between maize and Xanthium strumarium L.
Year: 2004
Type: article
Abstract: Interference between maize (Zea mays L. cv. Kneja 605) and Xanthium strumarium L. was studied in the experimental field of the Plant Protection Institute, Kostinbrod, in 2002 and 2003. Experimental design was a randomized block with four replicates. Infestation was artificially created and the weed density range was 0,5,15 and 25 plants/ m in maize rows during the crop cycle. Maize height, fresh weight, dry weight and leaf area were determined at the 4-5 leaf growth stage. Influence on maize grain yield was also established. The results showed a high competitiveness of X. strumarium with maize. Xanthium strumarium density has an economically and statistically significant impact on the maize characteristics studied. The impact goes in the following direction-an increase in X. strumarium density causes a highly significant decrease in maize height, fresh weight, dry weight and leaf area at the 4-5 leaf growth stage, as well as maize yield. The highest decrease in these morphological and productive properties of maize was in the variant of X. strumarium 25 plants/m. Weed density is a key factor in determining the relationship between maize and X strumarium. Statistical regression models may prove applicable in predicting a damage caused to maize grain yield through competition with X. strumarium.
