A split plot design with 6 treatments and 4 replications was performed on a piece of 5600 m2 land to find the most proper sowing depth of the Iranian oak (Quercus persica) seed in the Kamfiruz region in the Fars province of Iran. Different sowing depth of the seeds as minor treatments and divers levels of the manure as major treatments were used. The experiment commenced in autumn, 1994, but the boars destroyed the exprimentaJ site and ruined all of the sowed seeds. In 1995, the exprimental area was fenced and the experiment was Pertormed in autumn of the same year. Next spring, in 1996, when the seed germinated and emerged from the soil and started to grow, the plantlets were counted. Next fall, again. The experiment was repeated and the plantlets were counted in next spring, 1997. During the period of the experiment the condition of root systems and aerial parts were frequentJy visited by sampling. An MSTAT program were used to analyze the data. Results showed 5 and 7.5 centimeter sowing depth were the best treatments. The manure treatments showed no significant differences. The ratio of root length to aerial parts lenght was 6 and the ratios of dry weight to wet weight of aerial parts and dry weight to wet weight of the root were appreximatly 1 /15 and .1 /15 . respectvely.
