Abstract

In order to study of eco-physiological aspects of INTERFERENCEs of different lambsquarters, CHENOPODIUM ALBUM L. densities in two PLANTING PATTERNS of single cross CORN 704 and competitive effects of the weed on yield quality and quantity of CORN, an experiment was conducted at Miyandoab agricultural research station from 2004 to 2005. The experimental design was factorial in a rondomized complete block design with three replications. The treatments were: a combination of three levels of lambsquarters population (4, 10, 16 plants per meter of CORN row) and two PLANTING PATTERNS (common and two zigzag row) of CORN. The treatments lacking CORN weed in two PLANTING PATTERNS were considered as control. Seeds were planted on the sides and end of CORN rows in zigzag between CORN plants. Results showed that the COMPETITION of lambsquarters caused significant decrease in grain yield, biological yield and harvest index. Seed protein content of CORN was decreased but seed oil content increased. The effects of WEED DENSITY on studied characteristics of CORN was greater than those of different PLANTING PATTERNS. Competitition of weed significantly decreased LAI in comparison to the control. This decrease was considerable in higher weed densities. It was also greater in conventional planting pattern than two zigzag row planting pattern.
