INTRODUCTION
Weed invasion is a serious problem in crop plantation leading to the reduction in quality of crop produce and quantity of crop yields. The use of synthesis herbicides is widely considered as a quick and effective way to control weeds. However, their application results in chemical residues in agricultural products, and environmental pollution and contamination (Aktar et al., 2009). Global concern regarding the negative impacts of synthesis herbicides is increasing (Gandhi and Snedeker, 1999). Therefore, researchers are attempting to find alternative ways to minimize these problems and sustain agriculture management based on natural compounds.
Allelopathy is a biological process by which plants release allelochemicals into the surrounding environment in several ways. Allelochemicals interfere with the growth of other organisms by disrupting various physiological processes and also affecting rates of water uptake and plant...
