Abstract

In order to investigate the effect of PLANT DENSITY and PLANTING PATTERN on Leaf Area Index, Crop Growth Rate, Relative Growth Rate, Rate and Duration of Grain Filling in com, an experiment was conducted on Safi Abad, Khouzestan Province, in 2002. The experimental design was a split-factorial in randomized complete block design with tree factors, including PLANTING PATTERN, PLANT DENSITY and varieties, that replicated four times. Two promising hybrids of com, TWC600 and KSC720, were assigned to main plots, and factorial combination of plant densities (including.3 levels of 7, 8 and 9 plant per m2) and PLANTING PATTERNs (single and double row spacing) to subplots.Results indicated that early in the growing season before the appearance of reproductive organs, growth indices of both hybrids are similar. When the reproductive organs appeared (60 days after sowing), growth indices of KSC720 were greater than TWC600. These growth indices increased as PLANT DENSITY was increased. Further, increase of PLANT DENSITY caused grain filling duration decrease and grain filling rate increase. PLANTING PATTERN didn' t affect on grain filling rate and duration.
