Xanthium strumarium L. impact on corn yield and yield components

Invasion and impacts of Xanthium strumarium in Borena Zone of Oromia Region, Ethiopia

“…Many more previous findings support the results of present study. For instance, Hussain et al [10] reported row crops such as soybeans, cotton, maize, corns and groundnuts are mainly weeded by this invasive plant in many parts of the world. In groundnuts, X. strumarium has been reported to cause yield losses of 31%-39% at a density of 0.5 plants and 88% at 4 plants per m of row in USA.…”

“…strumarium germinates at a wide range of temperature and can invade large areas of wetlands. It is the major troublesome weed of row crops such as soybeans, cotton, maize, corns and groundnuts in many parts of the world [8,9] causing the highest reduction in yield of all annual weeds [10]. It invades pastures and grazing lands causing reduction in forage production and poisoning domestic animals which affect livestock production [11,12].…”

Impact of Invasive Alien Plant, Xanthium Strumarium, On Species Diversity and Composition of Invaded Plant Communities in Borena Zone, Ethiopia

“…In 1995, it was ranked as the fourth, fifth, sixth and seventh most troublesome weed in soyabean, cotton, maize and groundnut, respectively. 8 These rankings were based on distribution, abundance and difficulty of control. It can also invade pastures and grazing lands causing reductions in forage production.…”

Ankara ayçiçeği ekim alanlarında sorun olan domuz pıtrağı (Xanthium strumarium L.)‘nın meydana getirdiği ürün kayıpları ve ekonomik zarar eşiğinin belirlenmesi

“…Mısırda yapılan çalışmalarda domuz pıtrağının ekonomik zarar eşiğinin birçok alanda 1 bitki m -2 'den düşük olduğu hesaplanmıştır (Hussain et al 2014, Vazin et al 2008.…”

“…Domuz pıtrağı bitkilerinin yoğunluğu arttıkça kendi aralarında rekabete girmeye başlamaktadırlar (tür içi rekabet). Hussain et al (2014)'ın mısırda domuz pıtrağının EZE'ni belirlemek için yaptıkları çalışmada bulgularımıza benzer sonuçlar elde edilmiştir.…”
