Introduction
This bulletin summarizes the results of 1994 - 1995 yield performance tests of orchardgrass and tall fescue in Indiana.

The 1994 - 1995 Growing Season
Precipitation and temperature were favorable for the production of cool-season grasses in 1994. Three harvests of both grasses were taken. The studies were in excellent condition going into the fall.
The 1995 growing season was variable. Early season rain in 1995 resulted in higher yields for the first harvest across the state. Lack of mid-summer moisture and excessive heat limited growth on the grass stands at West Lafayette. Orchardgrass regrowth following the second harvest was infected with anthracnose and flea beetle feeding was also diagnosed; these stresses led to a third harvest not being taken. Tall fescue withstood the drought and no anthracnose or flea beetle feeding was evident; therefore, a third harvest of tall fescue was taken. Both studies are entering the winter in good condition.
Experimental Methods
Participating seed companies selected entries to be tested. Seed was sent to Purdue University for planting and evaluation.
Best management practices were administered to all studies. Optimum pH and fertility were provided and maintained. Hand weeding and herbicides were used as necessary to accomplish weed control. A flail-type forage harvester was used to harvest the plots. Hand samples were utilized for dry matter determination.
No yield data was taken in the establishment year of 1993; three harvests were removed in 1994.
Presentation and Interpretation of Results
Yields are reported as dry matter yield in tons per acre (T/A). Tables 1 and 2 summarize results of 1994 - 1995 yield trials conducted at West Lafayette. Table 3 describes primary growth stages referenced in Table 1 and 2.
In each table, varieties are listed in order of total yield to date. Within a column, varieties differing from each other by less than the respective LSD (least significant difference) were not significantly (probability > 0.05) different. Yields followed by an asterisk (*) are not significantly different from the highest value in the column.
The CV (coefficient of variability) is the ratio of the standard deviation to the grand mean. It is used as a measure of the precision of the experiment. Lower CV indicates lower experimental error in the trial.
Number of harvests within a year is listed at the bottom of each yield column.
Table 4 contains a listing of commercially available entries, along with marketer, address, phone number, and contact person as provided by the entrant company.
