Abstract

In order to study effect yield and yield components of com (Zea Mays L.) in COMPETITION with COMMON COCKLEBUR (Xanthium strumarium), an experiment was conducted in agriculture research station of Islamic Azad University branch of Gonabad in 2005.The experiments were carried out as factorial in a Randomized complete block design with three replications. In the experiments, the factors included com densities at 3 levels (7.5, 8.5 & 9.5 p/m2) and Velvetleaf densities at 5 levels (0, 2, 4, 6 & 8 p/m2). The com variety in experiments was 714. The results indicated that with an increase in velvetleaf density, the ear length, ear diameter, grain number in row, row number, grain number in ear, grain yield and biological yield of com decrease. Also with an increase com density, the grain number in row, row number, grain yield and biological yield of com increase. The economic thresholds density of velvetleaf was 0.1 to 0.15 plants in meter of square in com different densities, and increase with com density increase.
