G84-723 Maximizing The Use Of Farm Strip Plots, John Havlin, Roger Wesley Elmore

University of Nebraska-Lincoln Extension: Historical Materials

Strip plots are an effective means of comparing soil and crop management practices. Guidelines are given for establishing strip plots and evaluating the results. Farmers, extension and industry personnel, and researchers have a common interest in strip plots set out on farm fields to study various soil and crop management practices. Strip plots or tests are usually designed to compare differences between tillage methods, herbicide treatments, varieties, fertilizer sources or rates, methods of chemical application, and many other crop production inputs. Strip tests established in farmer fields could satisfy wider interests, and conceivably yield more useful information, if the planners …

G84-686 Irrigating Dry Beans (Revised September 1984), C. Dean Yonts, David S. Nuland

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes furrow and center pivot irrigation techniques and practices that will be helpful to both new and experienced dry bean growers.

Traditionally, dry bean production in Nebraska has been on irrigationd lands in the North Platte River Valley of the Panhandle. However, production acreage is expanding into new areas, north, south, and east from the North Platte Valley.

G84-702 Root And Soil Analayses For Nematodes In Corn, David S. Wysong, Eric D. Kerr

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to interpret laboratory results of samples submitted for nematode analysis and discusses ten species that are potentially damaging to corn.

Several kinds of plant parasitic nematodes (small, soil-inhabiting roundworms) are associated with root injury, poor plant color, stunted growth, and reduced grain yields in field corn. Symptoms caused by these pests are often confused with root rot diseases, nutritional deficiencies or climatic stresses. Special laboratory analyses are, therefore, necessary to determine if nematodes are the primary cause of reduced corn performance. Since corn growers may be unfamiliar with nematode diseases, the following discussion of laboratory reports …

G84-687 Soybean Planting Date: When And Why, Roger Wesley Elmore, A. Dale Flowerday

University of Nebraska-Lincoln Extension: Historical Materials

Soybeans differ from corn and sorghum in their response to planting date. This NebGuide provides guidelines that are helpful in making planting decisions for soybeans. Soybean response to planting date is important not only in years when planting is delayed by inclement weather, but also when weather does not disrupt the normal planting season. When planting is delayed, and in doublecrop situations, correct crop and variety planting decisions are necessary to obtain maximum yields. Early season freezes, hail storms, flooding, and other situations can reduce crop stands to a point where late planting is necessary. When planting is not delayed …

G84-737 Soybean Inoculation -- When Is It Necessary?, Roger Wesley Elmore

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses when soybean seed should be inoculated and why, and provides recommendations on inoculant types to use. Soybeans can obtain up to half of their nitrogen needs from the air when nitrogen-fixing rhizobia bacteria are present in the soil. Nitrogen fixation is a result of the symbiotic (beneficial to both) relationship of rhizobia and plants. Establishing rhizobia (inoculation) in a field that has never grown soybeans is needed to insure nitrogen fixation. Reinoculation may be necessary in fields with a past history of soybeans.

G84-725 Measuring Harvest Loss Of Dry Edible Beans, John A. Smith

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to measure losses before, during and after harvest operations, so that problems can be corrected and losses reduced. Harvesting dry edible beans in Nebraska normally includes three separate field operations--cutting, rodding or windrowing, and combining--over a period of three to seven days. The success of these operations is very dependent on equipment selection and adjustment, weather and field conditions, and operator skill.
