Influence of fall fertilization and moisture stress on growth

Five fertilizer treatments (+NPK, minus N, minus P, minus K, and tap water) and two wilt treatments (wilt, and non-wilt) were applied to container-grown Douglas-fir seedlings during the fall in the greenhouse. Seedling growth in the nursery was measured. Seedlings were outplanted in mid-winter and growth and performance after planting were evaluated near the beginning and at the end of the growing season. Seedling growth in the nursery and growth and survival after planting were substantially reduced in treatments not receiving nitrogen. Removal of phosphorus or potassium had no discernable effect on growth. The wilting practice was detrimental to seedling growth, both in the nursery and after planting.
