Abstract

In order to evaluate the effects of plant DENSITY and nitrogen levels on grain YIELD and DRY MATTER REMOBILIZATION in CORN, an experiment was conducted in Ardabil Agricultural Research Station in 2005, using a randomized complete block design as split plot with three replications. Three nitrogen levels (0, 75, and 150 kg.ha-1) were in the main plot, and the three plant densities (7, 9, and 11 plants.m-2) in sub plots. The result showed that DRY MATTER REMOBILIZATION increased with increasing plant DENSITY and decreased with increasing nitrogen levels. This conclusion was obtained also in DRY MATTER REMOBILIZATION from stem. The rate of remobilization contribution in grain YIELD was significantly affected by plant DENSITY and nitrogen levels interaction at 1% level probability. Means comparisons showed that the rate of remobilization contribution in grain YIELD increased with increasing plant DENSITY and decreasing nitrogen levels. Maximum the rate of remobilization contribution in grain YIELD occurred at the highest plant DENSITY with nitrogen at zero level. This conclusion was obtained also in DRY MATTER REMOBILIZATION from stem.
