G82-602 Predicting The Last Irrigation For Corn, Grain Sorghum And Soybeans (Revised August 1991), Norman L. Klocke, Dean E. Eisenhauer, Terry L. Bockstadter

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide presents criteria and "rules of thumb" for predicting the last irrigation for corn, grain sorghum and soybeans.

Determining when to apply the last irrigation of the season is an important water management decision. One extra irrigation may mean wasting an additional one to three inches of water and two to five gallons of diesel fuel per acre. On the other hand, applying that one extra irrigation could mean several bushels per acre in crop yield.

Ec81-760 How To Adjust Vertical Turbine Pumps For Maximum Efficiency, Thomas W. Dorn, Mark A. Schroeder, Paul E. Fischbach

University of Nebraska-Lincoln Extension: Historical Materials

The Agricultural Engineering Department has tested more than 500 pumping plants in the past 25 years. The average performance indicates that about 30 percent of the energy used for irrigation could be saved if all pumping plants operated at the Nebraska Performance Criteria.

There were many causes for poor pumping plant performance. Major causes were poor power unit performance, and poor pump performance often caused by improper pump adjustment.

This circular discusses proper pump adjustment to attain maximum efficiency.

Ec81-1240 Vegetable Gardening In Nebraska, Dale T. Lindgren, Laurie Hodges, Don Steinegger, Ralph E. Neild

University of Nebraska-Lincoln Extension: Historical Materials

Nebraskans are increasing their consumption of fresh vegetables — as appetizers, salads, side dishes, and snacks. Fresh vegetables are an integral part of a healthy, well-balanced diet. Although Nebraska's climate and soil are well-suited for many vegetables, most are supplied from out of the state, even during summer. Growing fresh vegetables can provide higher nutrition and flavor at less expense than buying fresh produce at the grocery store. A garden also can be a source of personal enjoyment and satisfaction.

This extension circular helps the gardener decide when, where, and how to plant and maintain a vegetable garden.

G79-464 Composting Municipal Sewage Sludge Slurry, Leon Chesnin

University of Nebraska-Lincoln Extension: Historical Materials

Municipalities can save operating expenses, eliminate pollution problems and increase the convenience of their waste management program by recycling their sewage sludge slurry in agricultural soils.

Sewage sludge slurries have from 2 to 10-percent solids depending on the treatment plant design and operation procedures. Sewage slurries with more than 8 percent solids are difficult to pump because of high friction in the pipe lines and pump mechanism. Sewage slurries can be applied to agricultural fields by gravity flow and sprinkler irrigation systems, as well as by tank trucks that either broadcast spray on, or inject the slurry into, the soil. …

G79-445 Soybean Variety Selection, Leroy V. Svec

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide has information on soybean characteristics that should be considered before selecting a variety to plant.

Soybean characteristics that need to be considered in making the selection of a variety to plant include maturity, yield potential, plant type, height, seed size, emergence score, lodging, shattering, and disease and insect resistance. Many years are required to develop a new variety from the time an initial cross of soybeans is made until the time seed is available on a widespread basis. The advance of a potential variety through the early generations may be accomplished with only a few seeds of the …

G79-471 Choosing Corn Hybrids, Lenis Alton Nelson

University of Nebraska-Lincoln Extension: Historical Materials

This publication explains what factors to consider and compare when selecting a corn hybrid and how to obtain recent hybrid test data. One of the most important decisions a corn producer makes is choosing the hybrid seed. Hundreds of hybrid names and numbers are advertised and offered for sale. Selecting the few that offer the greatest yield and profit potential requires time, effort, and study. This should be a continuous process for a corn grower because important information on new or established hybrids may be encountered at any time.

G78-426 Popcorn Production, Nora D'Croz-Mason, Richard P. Waldren

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses seed selection, soil requirements, production management, pest control, marketing and sale of popcorn.

Commercial popcorn production in the United States has always been concentrated in the Corn Belt. Iowa was the largest popcorn producer until the mid 1940s. As hybrids replaced open-pollinated varieties, popcorn production shifted to Illinois then to Indiana. During the mid 1970s popcorn production moved west, and in 1977 Nebraska became the nation's largest producer. During the 1980s popcorn acreage has fluctuated among states, but Nebraska often has had the nation's highest yield because 85 percent of its crop is irrigated.

G77-328 Irrigation Water Quality Criteria, Gary W. Hergert, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is intended to provide guidelines to help understand and interpret chemical water quality test results.

All well and stream waters contain dissolved minerals. The amounts and kinds of minerals vary from one location to another and may vary with time. When irrigation water is applied, the mineral salts are left in the soil after the crop has used the water. Most of these mineral salts are beneficial to crop growth and soil condition, but in some cases they may be harmful. Irrigation water quality problems may be caused by (1) total mineral salts accumulating so that crops no …

G77-340 Scheduling Irrigation By Electrical Resistance Blocks, Paul E. Fischbach

University of Nebraska-Lincoln Extension: Historical Materials

Delay of irrigation for a few days during a critical part of the growing season can be expensive. A week's delay in supplying irrigation water to corn or grain sorghum can reduce potential yield more than 30 bushels per acre.

Several methods are available to help you schedule the right amount of water at the right time. One of these methods uses electrical resistance blocks discussed in this NebGuide.

The information needed is: the number of acres that will be irrigated in one revolution of the center-pivot sprinkler system; the amount of time required to make one revolution of the center-pivot sprinkler system; and the rate at which your porportioning pump can inject a fertilizer solution into …

G73-58 Programmed Soil Moisture Depletion: Top Yields With Least Water (Revised), Paul E. Fischbach, Burt R. Sommerhalder

University of Nebraska-Lincoln Extension: Historical Materials

The development of automated irrigation has introduced a revised concept to irrigation water management that will mean savings of water and energy. By not completely refilling the root zone each irrigation, soil moisture storage capacity is left within the root zone to take advantage of any rainfall that occurs after an irrigation. Conservation of water is important because supplies are being depleted in many areas.

Rb34-6 The Relation Of Drouth To Water-Use In Nebraska, G.E. Condra

University of Nebraska-Lincoln Extension: Historical Materials
