Abstract:
This study was carried out to determine nutrient competition between wheat and three most commonly found weed species in wheat fields of Kahramanmaras City, Turkey. The weeds studies were animated oat (Avena sterilis L.), darnel ryegrass (Lolium temulentum L.) and wild mustard (Sinapis arvensis L.). The measured nutrients were P, K, Ca, Mg, Na, Fe, Mn, Zn and Cu. The results of paired t-test statistics showed that animated oat plant leaves removed significantly higher concentrations of Ca and Na and lower concentrations of P and Fe compared with accompanying wheat plant leaves. Wild mustard was better competitor for Ca, Mg, Na, Fe and Zn compared to wheat plants. Manganese was the only nutrient for which wheat was more successful for the uptake. Darnel ryegrass removed significantly higher levels of Ca, Na and Fe compared with the accompanying wheat plants.
