Effect of seed density and planting depth on quantitative characteristics of Cedrus deodara seedling
This investigation was carried out in spilt plot design with three replication and two treatments (depth of planting and seed density) in Pasand research station in North of Iran, Mazandaran province. Depth of planting performed in 4 levels including 1, 1.5, 2.5 and 3.5 cm and seed density including...

| Summary: | This investigation was carried out in spilt plot design with three replication and two treatments (depth of planting and seed density) in Pasand research station in North of Iran, Mazandaran province. Depth of planting performed in 4 levels including 1, 1.5, 2.5 and 3.5 cm and seed density including 40, 60, 80, 100 and 120 gr/m2. Germination duration, seedling collar diameter and height were recorded in year 3 after seed planting. Results showed that depth of planting has significant effect on germination duration and seedling survival. Seed density has significant effect only on seedling height growth. Seedling survival decreased with increseang of the depth of planting. Height growth of seedlings increased with increasing of the seed density. One can conclude that the best result could be obtained by planting of Cedrus seed in 1.5 cm depth with 80 to 100 gr/m2 seed density. |
