Allelopathic effect of Casuarina equisetifolia L. on wheat, associated weeds and nutrient content in the soil

Allelopathy is an ecological phenomenon that recently attracted researchers' attention as a new approach in weed control. Pot and field experiments were conducted to study the allelopathic effect of Casuarina equisetifolia L. leaf litter, one of three most common Casuarina species in Egypt. The influence was studied during two successive seasons (2012-2014) on wheat and associated weeds through foliar application of the aqueous extract and incorporating Casuarina leaf litter in the soil.
