Economic And Input-Use Efficiency Of Nitrogen Management Techniques In Non-Irrigated Maize Production, Katie J. Bathke Jan 2023

Economic And Input-Use Efficiency Of Nitrogen Management Techniques In Non-Irrigated Maize Production, Katie J. Bathke

Honors Theses

The efficiency of nitrogen (N) management has become a main concern in agricultural cropping systems for understanding the optimal N rate to help producers improve economically and reduce the exhaustion of natural resources environmentally. Nitrogen rates vary both temporally and spatially by the interactions of the soil environment and rainfall through a growing season. Thus, a site-specific approach can further optimize this variability with the understanding of the role soil variability plays in the N rate applied to a non-irrigated field. The objective of this study was to evaluate the various nitrogen treatments for their nutrient use efficiency and economic …

Nf02-520 Fungicide Spray Schedule For Home Garden Small Fruits, John E. Watkins, Jernnifer L. Chaky

University of Nebraska-Lincoln Extension: Historical Materials

Home grown strawberries, raspberries and grapes are a rewarding experience for the gardener as well as the consumer of the fresh fruits and jellies. If properly managed, these crops can be a source of enjoyment for years. To be successful, however, the home gardener must develop a sound integrated pest management (IPM) approach to controlling diseases and insect pests. A good IPM program makes use of cultural, varietal and chemical means of preventing or reducing disease losses.

This NebFact discusses which fungicides to use for which disease of small garden fruits and provides recommendations for a fungicide treatment schedule.

G92-1112 Lice Control On Cattle, John B. Campbell Jan 1992

G92-1112 Lice Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Identifying and controlling lice on cattle both are covered here.

Cattle lice may be the most underestimated livestock insect in terms of economic losses. The USDA estimates that U.S. livestock producers lose $125 million a year to cattle lice.

Heavy louse populations cause lowered milk production, loss of flesh, stunted growth, general unthriftiness and anemia. "Chronic" or "carrier" cows may abort due to louse-induced anemia. During severe winters, louse-infested animals are more susceptible to respiratory diseases.
