This study aims to determine the allelopathic activities of six plants that belong Asteraceae family such as China wedelia (Wedelia chinensis), sunflower (Helianthus annuus), cosmos (Cosmos bipinnatus), marigolds (Tagetes erecta), Mexico (Tithonia diversifolia), and zinnia (Zinnia elegans) by applying their methanolic extracts on barnyardgrass (Echinochloa crus-galli L.) mustard green (Brassica...

The variability in the emergence process of different populations was confirmed for two Echinochloa crus-galli populations, one from Italy (IT) and second Norway (NO). Seeds were sown 12 localities over Europe Middle East, patterns IT NO compared with those several local at each location. population pots buried to ground level. base temperature (Tb) estimated by (1) analysing logistic models ap...

Bu çalışma, dış mekân süs bitkisi saksılarındaki yabancı ot türlerini, bu türlerin yaygınlık ve yoğunluk değerlerini baskın türleri tespit etmek amacıyla, 2017 2018 yıllarında Sakarya ilinde yürütülmüştür. Tespit edilen türleri, (%) (adet/m2) değerlerine göre sınıflandırılmıştır. Çalışma sonucunda, üretim alanlarında kaydedilen 122 adet türünün 18 tanesi tek çenekli, 103 çift çenekli bir tohums...

In anaerobic soil disinfestation (ASD), amended with a carbon source undergoes conditions accompanied by changes in microbial community composition and an increase the concentration of organic acids, primarily acetic butyric gases that are deleterious to plant pathogens, insects, potentially weeds. The purpose this study was explore efficacy ASD different sources on inactivation propagules vari...

Understanding the effects of nitrogen (N) fertilizer on soybean-weed competition is essential for establishing a practical tool N application and weed management. A two-year field experiment was conducted in soybean located Bogatyrka (43.82° N, 131.6° E), Primorsky krai, Russia, to investigate multiple-weed interference (Glycine max) yield model these effects. Soybean loss caused by multiple we...
