Abstract

Plant DENSITY and PLANTING PATTERN are two essential factors for changing aerial arrangement and decreasing the weed interference potential. Effects of plant DENSITY and PLANTING PATTERN on growth and physiological indices of corn (Zea mays L.) under the COMPETITION condition with lambesquarters were studied in a randomized complete block design with three replication and factorial treatment arrangement at Aborayhan campus in 2003. Plant DENSITY treatment was at two levels: Recommended plant DENSITY (70000 plant ha-1) and 1/5 times recommended plant DENSITY (105000 plant ha-1). PLANTING PATTERN treatment was at two levels: One and two rows planting (planting on both of ridge sides) and four lambesquarters DENSITY levels: 0, 5, 10 and 15 plant m-1. The results showed that corn LEAF AREA INDEX (LAI), total DRY MATTER (TDM), CROP GROWTH RATE (CGR) and yield in different plant densities and PLANTING PATTERNs were decreased by present of lambesquarters. In higher corn DENSITY corn leaf area, DRY MATTER, CROP GROWTH RATE and yield increased than less corn DENSITY in through of growth season. Two row PLANTING PATTERN also increased LEAF AREA INDEX, DRY MATTER and CROP GROWTH RATE compare to one rows PLANTING PATTERN, although it had not the same effect as plant DENSITY.
