Because tillage promotes the germination of many weed species and freshly killed plant material favours the growth of microbial pathogens, we hypothesised that the incorporation of green crop residue should temporarily reduce weed seedling emergence relative to unamended soil. Soil with field-incorporated green crop residue was compared with non-amended soil in glasshouse experiments by sowing ...

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...
