Three-year average values for the economical level of nitrogen, yield, net return and corresponding economic rankings by variety for large round and small square bale enterprises are reported in Table 1. For the large round bale enterprise, the most economical variety (rank = 1) was Tifton 85, one of the three sprigged varieties of bermudagrass, which generated 5.1 tons per acre (8.5 large round bales per acre) and $160 net return per acre. The next best grass variety (rank = 2) for production of large round bales was the old world bluestem variety B Dahl, which generated 4.3 tons per acre (7.2 bales per acre) and $107 per acre in net return. In the case of large round bales, the remaining seven varieties were substantially less profitable than both Tifton 85 and B Dahl.
For the small square bale enterprise, Tifton 85 was the most profitable variety (rank = 1). However, it is important to emphasize that many equine enthusiasts do not prefer Tifton 85 due to its appearance. With this in mind, the next best variety (rank = 2) was Coastal, which is also a sprigged variety of bermudagrass. Coastal generated 3.8 tons per acre (138 small square bales) with the economical rate of 100 pounds of
N per acre providing for $184 per acre of net return. The Midland 99 sprigged variety of bermudagrass (rank = 3) generated a slightly lower net return of $167 per acre. The old world bluestem variety B Dahl also provided a respectable net return of $137 per acre (rank = 4). However, B Dahl is generally not preferred by equine enthusiasts.
In summary, our results showed that sprigged varieties of bermudagrass, especially Tifton 85 and Coastal, were economically superior to the seeded varieties. Net returns for all varieties were sensitive to the price of large round and small square bales, but the individual economic rankings were not. For lower hay prices, net returns for all varieties were lower, but the economic rankings remained unchanged and vice versa for higher hay prices. Similar results were found for both higher and lower nitrogen prices.
