Considerations For Crop Rotation From Alfalfa To Corn, Earl Creech, Matt Yost, Grant Cardon, Corey Ransom, Jason Clark

All Current Publications

The importance of rotating out of a declining alfalfa stand is well established. As the alfalfa stand ages, forage yield and quality decline, while weed, insect, and disease pressures increase. Terminating the stand and growing one or more other crops for several (2–3) years allows a grower to press the reset button on a piece of ground. These years of growing another crop will result in more productive alfalfa when a new stand is planted again.

Department of Agronomy and Horticulture: Faculty Publications

Farmers' participatory field trials were conducted at Madhuban, and Taraori, the two participatory experimental sites/locations of the Cereal Systems Initiative for South Asia (CSISA), a collaborative project of IRRI and CIMMYT in Karnal district of Haryana, India, during Kharif (wet season) 2010 and 2011. This research aimed to evaluate preemergence (PRE) and postemergence (POST) herbicides for providing feasible and economically viable weed management options to farmers for predominant scented rice varieties. Treatments with pendimethalin PRE fb bispyribac-sodium þ azimsulfuron POST had lower weed biomass at 45 days after sowing (DAS). At Madhuban, highest grain yield of scented basmati rice (3.43 …

Cattle Grazing Effects On Phragmites Australis In Nebraska, Jerry D. Volesky, Stephen L. Young, Karla H. Jenkins Pas

West Central Research and Extension Center, North Platte

Phragmites australis (common reed) is one of the most widely distributed flowering plants in North America. The introduced lineage occurs in wetland and riparian areas covering a range of climatic types. In Nebraska, an abundance of livestock could help to reduce P. australis with proper timing and grazing intensities. In 2011, a 3-yr study was initiated to evaluate targeted cattle grazing and herbicide effects and the nutritive value of this species. Treatments included a single application of imazapyr (Habitatt, BASF Corporation, Research Triangle Park, NC) herbicide applied in the first year, grazing, and a control. Grazing was applied for up …

Changes In Poa Annua Populations In Response To Herbicides And Plant Growth Regulators, Jesse Brown

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Poa annua (annual bluegrass; ABG) is an invasive weedy species in turfgrass. Herbicides and plant growth regulators (PGRs) are often used for ABG control, providing limited or inconsistent results. Identifying shifts in ABG populations in response to these treatments would be beneficial for understanding inconsistent control. Our research employed amplified fragment length polymorphic (AFLP) markers with the objective to determine if there are changes in genetic structure of ABG populations after multiple-year season-long control programs in three states. Annual bluegrass was sampled after the second or third year of seven different season-long ABG treatments consisting of herbicide or PGR applications. …

Each year new herbicide active ingredients and trade names are introduced and figuring out what a herbicide …

G03-1522 Damping Off Of Seedlings And Transplants, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

The shift toward more ecological means of pest control is a driving force in research and in growers' fields. Growers need to understand how the various pathogens causing plant disease respond to environmental conditions and cultural practices — what keeps the level of disease below an economic threshold and how these conditions can be developed and maintained for more sustainable production.

This NebGuide provides information on two common pathogens that cause seedling disease (damping off) in many crops. Although vegetable production is used in the examples, the principles apply to many cropping systems.

Ec02-178 Precision Agriculture: On-The-Go Vehicle-Based Soil Sensors, Viacheslav I. Adamchuk, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

Imagine that you are entering an unknown field and would like to estimate the productivity of the unfamiliar soil. You may pick up a handful of soil to evaluate its color and texture. You also can feel how difficult it is to break a clod apart, roll it into a ball or press out a ribbon. After repeating this procedure at different field locations, soil depths and times, you get a feeling of both spatial and temporal soil variability. Some of this variability can explain the non-uniformity of crop yield. If you collect soil samples and send them to a …

G97-1319 Management Of Smooth Sumac On Grasslands, John Ortmann, Katherine L. Miles, James L. Stubbendieck, Walter H. Schacht

University of Nebraska-Lincoln Extension: Historical Materials

The herbicide 2,4-D LV4 ester provides excellent low-cost smooth sumac control. Prescribed burning before herbicide application does not substantially improve sumac control, but may ease herbicide application and provide other benefits.

Smooth sumac (Rhus glabra L.) is a native deciduous shrub that forms dense thickets from widely spreading roots. It is found in the Sandhills, mixed-grass, and tallgrass areas throughout Nebraska. Introduced cool-season grasses, such as Kentucky bluegrass (Poa pratensis L.), invade the thickets, and production of desirable forage species is reduced below the dense canopies. Trees and other shrubs readily establish in aging sumac thickets, accelerating the …

G97-1323 Best Management Practices To Reduce Atrazine Runoff From Corn Fields In Nebraska, Thomas G. Franti, Fred W. Roeth, Gary L. Zoubek

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide presents best management practices (BMPs) which can be used to reduce atrazine runoff from dryland and irrigationd corn fields in Nebraska. Atrazine is one of the most widely used herbicides in Nebraska. It is used alone or combination with other herbicides for weed control in both dryland and irrigationd corn. Atrazine is popular because of its effectiveness and economy. However, environmental concerns are an increasingly important part of producer decisions regarding weed control, fertility and irrigation management practices. A public concern is reducing atrazine runoff to surface waters. Best management practices (BMPs) reduce the amount of atrazine at …

G96-1308 Management Of Eastern Redcedar On Grasslands, John Ortmann, James L. Stubbendieck, George Pfeiffer, Robert A. Masters, Walter H. Schacht

University of Nebraska-Lincoln Extension: Historical Materials

Developing an integrated control program including prescribed burning, herbicides, and cutting may be the best way to control eastern redcedar in Nebraska, according to recent research. Eastern redcedar is a serious threat to grassland productivity. Some control methods may be too expensive to use on grasslands, but in many cases, an integrated approach combining fire with more intensive follow-up methods will provide reasonable control at an acceptable cost.

Ec96-1768 Windbreak Management, James R. Brandle, Craig Stange

University of Nebraska-Lincoln Extension: Historical Materials

The windbreaks on your farm are an important part of the agricultural landscape. They provide protection for the farmstead, livestock, and crops; provide habitat for wildlife; and contribute to an overall healthy environment for you and your family. They are living systems with youth, maturity, and old age. Like any other living thing they need proper care and management in order to continue to function at their best.

Windbreak management requires an understanding of how your windbreak works. Your goal is to maintain the health and vigor of individual trees and shrubs while maintaining the overall structure of the windbreak …

Potential For Crop Residue To Restrict Herbicide Movement In Surface From Water Corn And Soybean Fields, William W. Witt

KWRRI Research Reports

As no-tillage and other conservation tillage practices continue to increase, it is important to have knowledge of herbicide adsorption on crop residue with regard to the potential for the herbicide to be removed from the residue and move with runoff water from the field into nearby surface waters. Previous research had compared herbicide adsorption to various residues, but it was difficult to make comparisons among these studies because the residues were from different crops or the amount of residue decomposition was different. The amount of "weathering" or "aging" of the residue at the time of herbicide treatment could alter the …

G95-1254 Weed Control In Alfalfa, Robert Wilson, Gail Wicks, Alex Martin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how weeds can be controlled in alfalfa. Weeds can interfere with alfalfa from the time of seeding through the life of the crop. Increased weed density in new seedings of alfalfa can decrease alfalfa stand. Weeds can also substantially reduce yield and quality of established alfalfa. In severe situations alfalfa yield can be reduced over 50 percent from weed competition (Figure 1). As weed content increases, the percentage of alfalfa in forage declines. Normally the quality of forage declines as the percentage of weeds increases.

G95-1241 Annual Broadleaf Weed Control In Winter Wheat (Revised January 1999), Gail` A. Wicks, Robert N. Klein, Alex Martin, Drew J. Lyon

University of Nebraska-Lincoln Extension: Historical Materials

This guide discusses preventive, cultural, and chemical weed control in winter wheat. The best weed control is obtained by using a combination of these methods. Winter and summer annual broadleaf weeds have an important economic impact on Nebraska winter wheat. They compete with winter wheat for water, light, space, and nutrients, reducing Nebraska winter wheat yields by an estimated 10 percent each year. The dollar loss, with wheat at $2.50 per bushel, is over $2.1 million per year. Weeds also slow harvest and increase combine repair costs. Producers may be docked at the elevator for excessive grain moisture and/or weed …

Ec94-138 Pigweed Identification: A Pictorial Guide To The Common Pigweeds Of The Great Plains, M.J. Horak, D.E. Peterson, D.J. Chessman, L.M. Wax

University of Nebraska-Lincoln Extension: Historical Materials

Several pigweed species are found in the Great Plains. Pigweeds commonly reduce crop yields and interfere with harvest. One means of controlling these weeds is through the use of herbicides. Recent research indicates that some pigweed species respond differently to various herbicides; therefore, proper identification is needed for good control.

This extension contains a generalized distribution map; photographs of seeds, seedling, and mature plants; and text describing other identifying features for each pigweed species. The species are grouped with others that have similar shape and form. The pigweed species listed in this publication are: redroot pigweed, smooth pigweed, Powell amaranth, …

G92-1071 Ridge Plant Systems: Weed Control, Robert N. Klein, Gail A. Wicks, Alex Martin, Russell S. Moomaw, Fred Roeth, Robert G. Wilson, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

Advantages and disadvantages of the ridge plant system, weed control before and at planting and economics of the system are discussed. Ridge planting combines tillage and herbicides to achieve improved weed control in row crops. Crop seed is planted into ridges formed during cultivation and/or ditching of the previous crop. In ridge planting, the planter follows the old row and ridge clearing sweeps or disks move the surface soil, residue and much of the weed seed out of the row. Weed seeds are deposited between the rows where, upon germination, they can be controlled with cultivation. Two cultivations are generally …
