An experiment was conducted to study the effect of tillage intensity and herbicide application on spring planted maize (Zea mays L.) and its weeds. The experiment comprised three tillage treatments i.e. no tillage, minimum tillage and conventional tillage and three treatments of herbicides viz. weedy check, Pendimethalin @ 990 g a.i. per ha as a pre-emergence herbicide and Atrazine @ 475 g a.i. per ha as a postemergence herbicide along with weedy check. The herbicides and tillage significantly decreased weed density, fresh and dry weight of weed, 1000-grain weight and grain yield. All treatments decreased weed density by 51.15-86.84 % and increase the grain yield by 6 to 71% compared with control. The study concluded that mould board ploughing + Pendimethalin @ 990 g a.i. per ha was more effective for controlling weeds and obtaining higher grain yield under the Faisalabad condition, Pakistan.
