Abstract

Lambsquarter (Chenopodium album) is one of the important weeds in CORN (Zea mays) fields. Field study was conducted at the Research Farm of Agricultural Faculty of Tehran University in 2002 to evaluate the effects of LAMBSQUARTER densities on grain yield of CORN and yield component. The experiment was conducted in factorial arrangement based on Randomized Completed Block Design (RCBD) with three replications to determinate, yield and component yield of CORN. Treatments include seven levels of LAMBSQUARTER densities (0, 5, 10,15,20,25 and 30 plant/m2) and two level of PLANTING PATTERN (conventional row and double row). Results showed that CORN grain yield and biomass, Harvest Index, number of seed in row, cob diameter and CORN height influenced by lamb's quarter densities but didn’t affect by PLANTING PATTERN. Thousand seed weight of CORN didn't affected by any treatments. Effect of PLANTING PATTERN on grain yield and number of seed row in ear was significant (a =0.95). Grain yield in double row pattern (8.87 ton/ha) was more than conventional pattern (8 ton/ha). Also, number of seed row in ear in double row pattern (14.03) was more than conventional pattern (13.42). Interaction between PLANTING PATTERN and lambs quarter DENSITY was significant in number of row in ear and cob diameter. The correlation between YIELD AND YIELD COMPONENT was significant. The highest correlation with CORN yield was biological yield(r=0.93**) and lowest correlation with CORN yield was 1000 seeds(r=0.2).
