Abstract

The objective of this study was to find out the most suitable date of seed sowing in view point of seed germination and quantitative and qualitative growth of (Cedrus deodara) seedlings in forest nursery. The experiment was conducted, using randomized complete blocks design with six replicates and six treatments and repeated for four years. The results were as follows:
1- Sowing date, year of experiment and their interaction had significant effects (P<0/01) on number of germinated seeds, 50 days and seven months after sowing date.
2- Sowing date, year of experiment and their interaction had significant effects (P<0/01) on average height of seedlings, seven months after sowing date.
3- The best moderate and worst dates of seed sowing, in view points of seed germinated numbers and seedling quality were as follows:
Best: 5 th March - 24 th february.
Moderate: 15 th - 25 th March.
Worst: 04 th - 14 th April.
