Abstract

To study 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 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 RCBD arrangement with three replications. The treatments were: two PLANTING PATTERNS (common and two zigzag rows) of corn and the combination of four levels of lambsquarters population (0, 4, 10 and 16 plants per meter of corn row). Weed seeds were planted on the sides and end of corn rows in zigzag between corn plants. Results showed that the competition of weed lambsquarters caused significant decrease grain yield and leaf chlorophyll content. Seed protein content of corn decreased but seed oil content increased. With increasing of weed competitive effects of weed population on studied characteristics of corn was greater than those of different PLANTING PATTERNS. Competition of weed caused a significant decrease in dry matter compared with check treatments. This decrease in the conventional planting pattern was greater than 2 zigzag- row planting pattern.
