1986 and 1y87 Plots--For data analysis, for each plot, the vigor <br />ratiny was multiplied by tiie number of plants of each plot. Ttiis <br />composite plant value was then used for comparisons between <br />treatments. <br />The composite plant values were then transformed to normalize the <br />data so that "analysis of variance" could be applied to the data. <br />This was accomplished by taking the logs of the composite plant <br />values. All results presented are in the original units of composite <br />plant values. Retransformations of tire data (using the antilog) were <br />used to accomplish this. Tne log transformation pulls in extreme <br />values towards the center of the distribution. <br />The Daubenmire cover class midpoints for cheatgrass and blue mustard <br />were summed to estimate the percent weeds for each plot. <br />Although the same information was collected in 1985 through 1987, the <br />actual data collected in 1985 was different than the data collected <br />in 1986 and 1987. Thus, comparisons cannot be done for differences <br />between 1985 and 1980 or 1987, though, the same comparisons can be <br />made within years for 1985 as are none for 198b and 1987. <br />Statistical Plethods Used <br />Analysis of variance was used for all anaiyses for all years. Two <br />separate analyses were done for each year. The more powerful <br />analysis assessed the effect of each factor; seed mix, imprint, much, <br />phosphorus, and herbicide. This analysis showed little interaction <br />between the factors. The lack of interation implies additive <br />treatments which in turn implies that the very best treatment should <br />be the one which combines the factors determined by by the ANOVA. A <br />further analysis was done to determine which, if any, treatment was <br />best. This was a one way analysis of variance with the 12 treatments <br />specified by the two levels of much, two levels of phosphorus, and <br />three levels of herbicide was better than others. This analysis is <br />not nearly as sensitive as the previous analysis, as the variability <br />is not partitioned into components due to seed mix, imprint, mulch, <br />phosphorus, and herbicide as it was for the more sensitive analysis. <br />In tt~e main analysis, the average of early and late Glean application <br />was used as one treatment category. A second analysis was then done <br />to determine if differences existed between the ear]y and late <br />application of Glean. This method did not give double weight to the <br />Glean plots, as using early and late Glean as separate categories <br />would have. <br />The qualitative information collected in 1984, was used to make <br />several comparisons. These comparisons pointed out that by October <br />the herbicides were beneficial for establishment of seeded species. <br />Seed mixtures a and B had the best emergence and all seed mixtures <br />had more seedlings present in October than in play due to continuing <br />germination. Replication I had tiie best emergence of seeded species <br />and also more weeds. A difference in species of broad leaved weeds <br />was also noticed with blue mustard abundant in Iiay and Russian <br />5 <br />
