Maize (Zea mays L.) is an important cereal crop that ranks third in the world after wheat and
rice (Mahmoodi and Rahimi 2009), with an annual cultivation area of more than 150 million …

One of the most important stress factors for maize (Zea mays L.) production is the
competition with weeds for growth resources, which reduces crop yields. A field study in …

Weeds and crops compete for the same resources of nutrients, water, space and light for
