The experiment was conducted to test the effects of ectomycorrhizal inoculation and soil moisture regime on growth and nutrient uptake of Pinus rigida seedlings. Two-year-old seedlings inoculated with either Pisolithus tinctorius or Thelephora terrestris were used for this experiment. There were two moisture treatments and four phosphate treatment levels with three replications. Height and root collar diameter growth and dry weight increase were measured and nitrogen, phosphorous, and potassium in the tissue were analyzed three months after the initiation of phosphate and moisture regime treatment. Results are as follows; 1) Height growth of seedlings was not affected in all treatments. (mycorrhizae, fertility, moisture). 2) High moisture regime increased root collar diameter growth 2.7 .times as large as low moisture regime. 3) In low moisture regime, net production increased 26% in seedlings inoculated with Pisolithus tinctorius and increased 72% control seedlings. 4) In high moisture regime, net production of inoculated seedlings with Pisolithus tinctorius increased four times as much as that of control seedlings but increased P₂O_5 in fertility level did not affect net production. 5) In uptake of nitrogen, phosphate, and potassium, Pisolithus tinctorius - inoculated seedlings increased uptake by 1.9, 1.8, and 1.5 times, respectively, as much as control seedlings. 6) Increase in P₂O_5 fertility level enhanced the uptake of P₂O_5 in Pisolithus tinctorius - inoculated seedlings, but not affected the uptake of P₂O_5 in control seedlings. 7) Increase in P₂O_5 fertility levels enhanced the uptake of K₂O in Pisolirhus rinctorius - inoculated seedlings.
