G89-954 A Guide For Managing Poultry Insects (Revised April 1996), John B. Campbell
University of Nebraska-Lincoln Extension: Historical Materials
Major insect pests of Nebraska's poultry population are identified and treatment recommendations are given.
For many years poultry production in Nebraska has consisted primarily of large operations of layer hens. In recent years, however, broiler production has increased in southeast Nebraska. There are also some large turkey production units. Extreme competitiveness in the poultry industry has resulted in narrow cost-profit margins. Poultry operations cannot allow ectoparasitic and nuisance insects to interfere with production, nor can they afford high pest control expenses. For production to be profitable, poultry production must be managed to reduce the incidence of insect pests.
Poultry are …

G89-902 Intensive Gardening Techniques, Betty Besal
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes techniques which will allow the gardener to grow more vegetables where space may be limited.
For some people, a small-sized garden is preferable to a larger one. Smaller gardens require less labor and expense than larger gardens. Decreasing garden size provides more yard space for other activities. The gardener can concentrate soil improvement efforts in a smaller area, and, with careful management, small gardens can produce sufficient vegetables for fresh eating during the growing season, and perhaps extra produce for preserving.
