G97-1341 Landscapes For Shade (Revised April 2003), Anne Streich, Donald E. Janssen, Roch E. Gaussoin, Steven Rodie

University of Nebraska-Lincoln Extension: Historical Materials

The cooling effect of a shade garden in midsummer can be one of life's great pleasures. The combination of shade and dappled sunlight encourages people to stop and enjoy a cool, quiet respite from a busy day.

This NebGuide includes information on gardening in the shade.

Ec97-275 Effect Of Lactation Length On Sow Reproductive Performance, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

As lactation length decreases there is an increase in the weaning-to-estrus interval, a decrease in farrowing rate, a decrease in subsequent litter size and an increase in pigs weaned per sow per year. Because of herd-to-herd differences in the influence of lactation length on reproductive performance, each farm should conduct a preliminary study to evaluate the effect of the lactation length being considered before implementing the “new” weaning age of piglets.

Ec97-219 1997 Nebraska Swine Report, Duane Reese

University of Nebraska-Lincoln Extension: Historical Materials

The 1997 Nebraska Swine Report was prepared by the staff in Animal Science and cooperating Departments for use in Extension, Teaching and Research programs. This publications deals with research on swine reproduction, breeding, health, nutrition, economics, and housing.

Ec97-276 Management Strategies For Pen-Mating Female Pigs, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

The master control switch of a pork production enterprise is weaning day. Pork production managers have little or no control concerning when a weaned female will cycle or how long she will be in estrus after weaning. When females are pen-mated, the producer needs to use management procedures to prevent an excessive number of estrous females from expressing the standing response at the same time, try to manage estrous females so that they are bred at the proper time, try to manage boars so they maintain an adequate level of fertility, evaluate boars for level of sexual behavior before and …

Ec97-274 Management Of Replacement Gilts For Efficient Reproduction, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

Successfully introducing replacement gilts into the breeding herd is an important aspect of breeding herd efficiency. To attain herd efficiency, females must ovulate adequate numbers of viable ova, express estrus, show willingness to mate and conceive in a regular manner. If these qualities are properly developed, pregnancy rate and litter size will be maximized. A gilt development and management program needs to be designed for gilts from birth to farrowing their first litter.

Nf97-355 House Finch "Eye" Disease, Eva Wallner-Pendleton, Ron J. Johnson, John Dinan

University of Nebraska-Lincoln Extension: Historical Materials

A newly-recognized disease that causes swollen eyelids and weepy eyes in house finches was confirmed in Nebraska in 1996 and has been observed as far west as McCook. Other symptoms of this emerging disease include wet, matted feathers around the eyelids and face, weight loss, fluffed feathers, inactivity, loss of sight, and eventual death in some affected birds. This disease, caused by a strain of the bacteria-like organism Mycoplasma gallisepticum, was first observed in several mid-Atlantic and eastern states in 1994. It has now spread to Canada, all of the eastern and Midwestern United States, and as far west as …

G97-1330 Apple Scab, Diane A. Merrell, Donald Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Apple scab, caused by the fungus Venturia inaequallis, occurs worldwide wherever apples are grown. Scab is one of the most important diseases of apples and crabapples in Nebraska.

This NebGuide discusses the apple scab disease, its symptoms, disease cycle, and cultural and chemical control. Varieties of apples and crabapples are listed according to their degree of resistance.

Nf97-328 A Guide To Grasshopper Control In Cropland (Revised May 2004), Gary L. Hein, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Grasshoppers have been a major concern to farmers and ranchers since Nebraska was first settled. The potential for devastation, while still serious, is not as great as it was 100 years ago because many of the prime grasshopper breeding areas along the eastern slopes of the Rocky Mountains are now under tillage. Statewide, grasshopper populations fluctuate in cycles with large numbers occurring for two to four years, followed by moderate numbers for several years.

This NebFact discusses grasshopper damage to cropland, how to determine when control is required and methods of control.

G97-1340 Firming Irrigation Furrows To Improve Irrigation Performance (Revised November 1999), Dean E. Eisenhauer, C. Dean Yonts

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how using a furrow firming wheel improves furrow irrigation performance.

Nearly half of the irrigated acres in Nebraska are furrow irrigated. Higher pumping costs, water restrictions and water shortages are all factors encouraging efficiency-improving irrigation practices. Generally, reduced efficiency with furrow irrigation occurs in two ways: runoff or deep percolation. Although hard to eliminate, runoff can be controlled by: tailwater reuse systems; changing furrow stream size; or changing irrigation set time. Deep percolation is the loss of water below the root zone. The amount of deep percolation caused by irrigation is difficult to estimate unless irrigation application …

G979-1337 Application Uniformity Of In-Canopy Sprinklers (Revised November 1999), C. Dean Yonts, William L. Kranz, Derrel L. Martin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes water management and system design considerations when using in-canopy sprinklers for center pivot irrigation systems. The goal, when using center pivot irrigation, is to uniformly distribute water on the soil surface. Uniform application of water combined with uniform infiltration of water into the soil gives plants equal access to water. As a method to reduce energy costs, many producers are converting their center pivot systems from high to medium or low pressure sprinkler packages. In response, sprinkler manufacturers have developed new devices for use above and below the center pivot pipeline to uniformly apply water at lower …
