Effects Of Row Width And Seeding Rate On Yield And Other Agronomic Characteristics Of Three Soybean Cultivars, Russell Kithcart
Effects Of Row Width And Seeding Rate On Yield And Other Agronomic Characteristics Of Three Soybean Cultivars, Russell Kithcart
Masters Theses & Specialist Projects
Soybeans have traditionally been grown in rows wide enough to allow mechanical cultivation and to increase lodging resistance. Improved cultivars and herbicides have permitted farmers to obtain yield advantages from narrower rows. The growth response of soybeans to variations in row width and seeding rates depends upon the cultivar and geographic location.
“Williams,” “Mitchell,” and “Essex” cultivars were planted at row widths of 18, 36, 54, and 72cm. at seeding rates of 33, 67, 100 and 134 kg/ha in multi-row plots. Data were collected from each plot for seed yield, lodging, plant height, height of lowest pod, seed and population …

University of Nebraska-Lincoln Extension: Historical Materials
If you are using herbicides on alfalfa, sugarbeets, soybeans, or fieldbeans, information in this Guide will help you apply them at the proper time for best weed control with a minimum of crop injury. Proper timing of postemergence herbicides is essential to achieve maximum weed control with minimum crop injury. As field crops grow and mature, their tolerance to herbicides changes. As a general rule, annual and biennial weeds are more susceptible to postemergence herbicides when they are in the seedling stage, becoming increasingly difficult to control as they mature. The grower is thus faced with the problem of when …

Agronomy Notes
Field investigations on the effect of foliar fertilization were continued on soybeans during 1977. Results from our 1976 studies have previously been published.
In 1976 we tested a material produced by TVA. We used the same TVA-material in 1977 and in addition, included a commercially available product (Foliantm, manufactured by Allied Chemical Corporation).
