G89-953 Soybean Chlorosis Management, Edwin J. Penas, Richard A. Wiese

University of Nebraska-Lincoln Extension: Historical Materials

Four management ideas that make it possible to grow soybeans on alkaline soils are covered here.

Chlorosis (yellowing) in soybeans can be a problem wherever soybeans are grown on alkaline soils in Nebraska. Serious chlorosis is likely to occur when the pH of these alkaline soils is 7.5 or higher. Soybean chlorosis problems occur in the Platte and Elkhorn River Valleys and, to a lesser extent, in the Republican and Loup River Valleys, and on high lime soils in central and western Nebraska. Not all high pH soils cause chlorosis of soybeans even though they are alkaline.

G89-924 Fertilizing Proso Millet (Revised December 2002), Jurg M. Blumenthal, David D. Baltensperger

University of Nebraska-Lincoln Extension: Historical Materials

Soil testing and fertilization of proso millet with nitrogen, phosphorus, potassium and other nutrients is discussed. Management practices that provide an adequate, but not excessive, supply of plant nutrients are essential for top yields of proso millet in the High Plains.

G89-932 Minimum Center Pivot Design Capacities In Nebraska, William L. Kranz, Derrel L. Martin, Greg Lackas

University of Nebraska-Lincoln Extension: Historical Materials

Factors to consider in choosing an appropriate center pivot design are covered here. Irrigators investing in a center pivot irrigation system need to consider this important question: How much supplemental water is required by the crop? Irrigation system capacity needed to meet crop requirements is defined in units of gallons per minute (GPM) or gallons per minute per acre (GPM/AC). If the system capacity is too low, crop stress occurs during some portion of the growing season. If the capacity is too high, surface runoff may result, or capital investment for the pumping plant and center pivot may be greater …

G89-906 Barley Yellow Dwarf Disease Of Barley, Oats, And Wheat, John E. Watkins, Leslie C. Lane

University of Nebraska-Lincoln Extension: Historical Materials

The symptoms of barley yellow dwarf are covered here, as are disease occurrence and spread, and control.

Barley yellow dwarf (BYD) is distributed worldwide. It is the most economically important disease of barley and oats in North America. Barley yellow dwarf, wheat streak mosaic (WSM) and soil-borne wheat mosaic (SBWM), are three virus diseases that caused serious cereal grain yield losses in Nebraska during the last decade.

Since the mid-1980s barley yellow dwarf has become increasingly widespread in Nebraska, and now is a serious concern to oat and wheat producers. Outbreaks occasionally reach epidemic proportions as occurred in wheat in …
