Effect of fertilizer at planting on survival of grass transplants, planting occurred in 1994. See Table 2 for species codes. The seedlings were planted September 13-16, 1993. Dibble bars were used for the larger containers and a sharpshooter shovel for the 1 inch 3 container. Treatments, seed source and container size, were randomly allocated in each planting block. Two planting sites were used in the study. Both sites were near the base of the slopes. The treatment design was a factorial design of seed source (four), and container size (three) for 12 treatments. The outplanting design was a split plot design with the two main plots being the planting sites. Each main plot consisted of six randomized complete blocks. Each treatment was represented in each block by a 10 tree row plot. The response unit was the average of the 10 tree row plot of each treatment within each block. Because the plots were installed at the base of slopes some areas were lost by covering by overburden material. Survival values were adjusted to be a percentage of the number of living seedlings based on total number of non-covered seedlings. RESULTS Smaller seedlings were more prone to covering than were larger stock types (39% compared to 30%). Survival was greater for the largest two stock types, 10 in 3 and 7 in 3 (Figure 3). Some treatments had 90% survival. The smaller stock type, 1 in 3 , had a survival rate of 5%. The poorest performing seed source was the southern seed source (seed zone 170). The three other seed sources performed comparably, with an average survival of 24% (Figure 4). ��
