G88-876 Ridge Plant Systems: Equipment, Elbert C. Dickey, Paul J. Jasa, Robert N. Klein, Dean E. Eisenhauer, David P. Shelton, Bryn J. Dolesh, John A. Smith

University of Nebraska-Lincoln Extension: Historical Materials

Ridge plant systems, ridge cleaning equipment, planter stabilizing attachments, cultivation and ridge management are discussed here. Ridge plant systems are methods of planting crops into a ridge formed during cultivation of the previous crop. Such systems combine tillage and herbicides to control weeds. Weed seed and residue lying on the soil surface are pushed from the ridge to the area between the rows by row-cleaning devices on the planter. Crop seed is planted into the old row in a cleanly tilled strip at an elevation slightly higher than the row middles. A band application of herbicide behind the planter typically …

G88-884 Ecofarming: Selecting Corn And Grain Sorghum Hybrids, Planting Dates, And Planting Rates In A Winter Wheat--Row Crop--Fallow Rotation, Robert N. Klein, Gail A. Wicks, P. T. Nordquist

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses selecting corn and sorghum hybrids, factors that affect yield, plant populations, and more. Treating winter wheat stubble with herbicides after harvest, and then planting corn or grain sorghum in the untilled stubble the next spring, is a practice used for over 15 years in many parts of the Central Great Plains. The residue protects the soil from wind and water erosion. This method of farming is one of the most effective soil and water conservation practices adapted in this century.

G88-875 Weed Control In Soybeans, Russell S. Moomaw, Robert N. Stougaard, Alex Martin, Fred Roeth, David Mortensen

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides information on mechanical and chemical weed control methods, including herbicides to use for preplant incorporated, preemergence and postemergence. Soybeans are a relatively easy crop to grow. Limited insect and disease problems presently are associated with their production in Nebraska. Weeds, however, are a major production problem. Each 100 pounds of weed growth results in a one bushel loss in soybean yield. Weeds that emerge with the crop and remain in the row are the strongest competitors. Those that emerge later than six weeks after planting have little effect on yield, so it is important to focus on …

G88-888 Flow Control Devices For Center Pivot Irrigation Systems, William L. Kranz

University of Nebraska-Lincoln Extension: Historical Materials

Several factors contribute to the need for sprinkler flow rate regulators. This NebGuide discusses them.

Many center pivot irrigation systems operate on undulating terrain. Systems operated on undulating terrain experience large pressure differences in the pivot pipeline. Since water distributed by each sprinkler is determined by the pressure in the pipeline, water applied by these systems can be non-uniform.

Pressure regulating devices that equalize the flow of water from individual sprinklers have become more common since uniform water application may save water and increase overall crop production. When installing a sprinkler package on a new system or replacing sprinklers on …
