Two field experiments were carried out during two successive winter seasons of 2010 and 2011, and two successive summer seasons of 2011 and 2012 at the agricultural research and experiment station, of Faculty of agriculture, Cairo oniversity, Giza, Egypt. Aims of this study were to: evaluate effects of weed control methods on canola conventional (CT) and zero tillage (ZT) practices and weed control methods on summer crops (maize and soybean) weed parameters and yield components for studied crops. Laboratory experiments were carried during 2013 in poland, Faculty of chemistry and second part between weed research lab in Faculty of agriculture, Cairo university and central agricultural of pesticides Lab., Ministry of agriculture, Egypt. canola yield and its components, chemical and mechanical weed control increased seed yield / feddan and reduction fresh weight of weeds / m² at 55 days after sowing (DAS) in canola plots during both successive winter seasons. Soybean seed yield per feddan increased by hoeing and its interaction with ZT and hoeing weed control on preceding crop increased soybean seed yield per feddan during both seasons and decreased number of weeds/m² at 55 DAS
