Nf04-616 Managing Foliar Diseases Of Winter Wheat With Fungicides Treatment Criteria, Profitability And Products, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

The leaf rust, stripe rust, powdery mildew, tan spot, Septoria leaf blotch and occasionally stem rust comprise the primary foliar disease of wheat in the central Great Plains. In southeast and south central Nebraska, leaf and stripe rusts, powdery mildew and Septoria leaf blotch are the most common and important foliar diseases. Tan spot predominates in the dryland wheat-fallow-wheat or ecofallow cropping systems found in the west central, southwest and Panhandle areas of Nebraska.

This NebFact discusses the treatment criteria, profitability of treatment, and the treatment products and timing of managing foliar diseases of winter wheat with fungicides.

G03-1511 Calibration Of Sprayers (Also Seeders), Robert N. Klein

University of Nebraska-Lincoln Extension: Historical Materials

Applying the correct rate of a product is an important part of obtaining good results with both seeders and pesticide sprayers. With seeders too little seed reduces crop yields and increases weeds while too much seed increases cost and may reduce yields. With a pesticide application, too little product can mean poor control, while too much can mean crop injury, extra costs, and possible residue on the crop and/or carryover. This NebGuide discusses the various methods for calibrating sprayers and seeders and related application information.

G03-1521 Using Corn Hybrid Yield Data To Improve Selection Of Rapidly Changing Hybrids, Robert N. Klein, Lenis Alton Nelson, Roger Wesley Elmore

University of Nebraska-Lincoln Extension: Historical Materials

How often should you change hybrids? One might conclude that to maximize corn yield, hybrids must be constantly replaced. Choosing the proper hybrid can greatly enhance crop production profitability. This NebGuide illustrates how to use corn hybrid test data and adjust it to your farm when selecting seed.

G03-1528 Recommended Seeding Rates And Hybrid Selection For Rainfed (Dryland) Corn In Nebraska, Robert N. Klein, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

Differences in climate between Lincoln and Scottsbluff are as great as from Lincoln to the east coast of the United States. These climatic differences across the state greatly affect recommended seeding rates for rainfed corn in Nebraska. This NebGuide provides information useful in assessing accumulated growing degree days, soil type and field conditions, average precipitation, and the field's microclimate when determining seeding rate for dryland corn.

G03-1527 Annual Forages For The Nebraska Panhandle, Burt A. Weichenthal, David D. Baltensperger, K. P. Vogel, S. D. Masterson, J.M. Blumenthal, J.M. Krall

University of Nebraska-Lincoln Extension: Historical Materials

Annual forages have value as pasture, green chop, silage, and hay. With adequate soil moisture, these forages grow very rapidly during their appropriate growing seasons. Advantages and disadvantages of various annual forages, results of dryland and irrigated forage trials, tips for achieving quality forage, and issues related to animal health and feeding forages are discussed in this NebGuide.

Ec01-872 Nebraska Crop Budgets 2001, Roger Selley, Tina N. Barrett, Richard T. Clark, Robert N. Klein, Steve Melvin

University of Nebraska-Lincoln Extension: Historical Materials

The 2001 Crop Budgets contains a list of representative field operations and materials that provides a reminder of items typically invovled in producing the crop. The budgets are presented in a worksheet format with a "Your Estimate" column for recording modifications in costs.

This publication covers the following crops: Forages -- alfalfa, annual hay, corn silage, grass, grass hay, and pasture. Grain -- corn, dry beans, grain sorghum, proso millet, oats, soybeans, sugar beets, sunflower, wheat.

Ec95-1873 Cultural Practices That Influence Wheat Diseases, John E. Watkins, Robert N. Klein, Paul C. Hay, Lenis Alton Nelson

University of Nebraska-Lincoln Extension: Historical Materials

The health of a wheatcrop is determined well before the crop is planted. It is often the result of subtle factors in the management history of the field, including varieties, seed quality, seedbed, planting date, residue management and post harvest weed control. Wheat health management practices before the crop is planted must limit, as much as possible, the number of production hazards that must be dealt with after planting. Important diseases influenced by cultural practices include crown and root rot, wheat streak mosaic, soil-borne wheat mosaic, barley yellow dwarf, leaf rust, smut diseases, scab, Cephalosporium stripe and tan spot.

Ec94-132 Freeze Injury To Nebraska Wheat, Robert N. Klein, Drew J. Lyon, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska’s adverse weather conditions affect winter wheat during much of its growth. The newer varieties of wheat have increased winter hardiness, and better management practices have reduced winter injury of winter wheat, yet low temperature injury during winter and spring can be destructive. Wheat has little resistance to low temperatures after it begins growing in the spring; therefore, injury from freezes at this time can occur in any part of the state. This publication describes temperature conditions that cause winter injury, symptoms of injury at different spring growth stages, and management practices to use when wheat is injured.

G89-955 Nozzles — Selection And Sizing (Revised February 2003), Robert N. Klein, William P. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

The proper selection of a nozzle type and size is essential for proper pesticide application. The nozzle is a major factor in determining the amount of spray applied to an area, the uniformity of application, the coverage obtained on the target surface, and the amount of potential drift. This NebGuide covers nozzle description, recommended uses and orifice sizing for sprayers.

Ec88-116 Universal Soil Loss Equation: A Handbook For Nebraska Producers, A. J. Jones, D. Walters, W. G. Hance, Elbert C. Dickey, J.R. Culver

University of Nebraska-Lincoln Extension: Historical Materials

Tons of soil are lost from agricultural fields in Nebraska each year as a result of water erosion. The accelerated loss of topsoil reduces the availability of plant nutrients and water needed for optimum crop production. In addition, the eroded soil frequently moves into surface waters causing sediment to be deposited in streams and reservoirs and nutrients to be released into other biological systems. The purposes of this workbook are to provide an understandng of how soil erosion estimates are determined, to estimate erosion control resulting from numerous cropping systems, and to inform the producer of alternative practices which may …
