Optimal Plant Population And Nitrogen Fertility For Dryland Corn In Western Nebraska, Jurg M. Blumenthal, Drew J. Lyon, Walter Stroup

Panhandle Research and Extension Center

Dryland corn (Zea mays L.) production increased more than 10-fold from 1995 through 2000 in semiarid western Nebraska. Corn population and N fertilizer management recommendations are needed for this area. The objectives of this study were to determine the influence of plant population and N fertility on corn yields in semiarid western Nebraska. In 1999 and 2000, experiments were conducted each year at four sites. Factorial experimental treatments were five plant populations (17 300, 27 200, 37 100, 46 900, and 56 800 plants ha^-1) and five N fertilizer rates (0, 34, 67, 101, and 134 kg …

Pearl Millet And Grain Sorghum Yield Response To Water Supply In Nebraska, Nouri Maman, Drew J. Lyon, Stephen Mason, Tom D. Galusha, Robert Higgins

Panhandle Research and Extension Center

Pearl millet [Pennisetum glaucum (L.) R. Br.] is a drought-tolerant crop that may serve as an alternative summer crop in Nebraska. Field experiments were conducted in 2000 and 2001 near Sidney and Mead, NE, to determine the water use efficiency (WUE) and yield response to water supply at critical developmental stages of pearl millet and found grain sorghum [Sorghum bicolor (L.) Moench]. Four water regimes were used: (i) no irrigation, (ii) single irrigation at boot stage, (iii) single irrigation at mid–grain fill, and (iv) multiple irrigations. Pearl millet grain yields were 60 to 80% that of grain sorghum. …

Dalea Villosa ‘Sandhills Satin, Dale T. Lindgren, Daniel Schaaf, James H. Locklear

West Central Research and Extension Center, North Platte

Daleas (prairie-clovers) are annual or perennial, warm season legumes found from southern Canada to South America (Barneby, 1977). They are an important group of legumes in native grasslands of the Great Plains. The genus name Dalea L. is in honor of Samuel Dale, an English botanist (1659–1739). Until recently, these plants were classified in the genus Petalostemon Michx. (Weber, 1990). The prairie-clovers have potential as attractive garden ornamental plants in addition to their importance as constituents of prairies and pastures. They have uses, along with other native species, for beautification of roadsides, rest areas, parks, and recreation areas, and for …

Ec03-176 Noxious Weeds Of Nebraska: Musk Thistle, Fred Roeth, Steven R. Melvin, Irvin L. Schleufer

University of Nebraska-Lincoln Extension: Historical Materials

Musk Thistle is an introduced invasive broadleaf weed native to Europe, North Africa, and Asia. In these areas it is a minor weed because natural enemies keep its population low. When the plant was introduced into North America, its natural enemies were left behind. Without these natural checks, the thistle is able to thrive and compete with native vegetation. This Extension Circular discusses the history, biology, identification, distribution and control of the musk thistle.

Determination Of The Salt Tolerance Of Some Barley Genotypes And The Characteristics Affecting Tolerance, Seydi̇ Ahmet Bağci, Hasan Eki̇z, Ahmet Yilmaz

Turkish Journal of Agriculture and Forestry

The salt (NaCl) tolerance of 8 barley genotypes was investigated. Plants were grown hyroponically in Hoagland solution at 5 different NaCl concentrations. Germination percentage, shoot and root length, shoot and root dry weight, salt tolerance percentage, and K and Na concentrations in the shoots and roots were evaluated. Salt tolerance percentage, which is calculated from the germination percentage and dry weight production, was the most reliable criterion. On the other hand, with some exceptions, high K concentration and K/Na ratios were other potential criteria. Erginel-90 and WBELT-10 showed high levels of tolerance; and Obruk-86, Anadolu-86, Kıral-97 and Karatay-94 showed medium …

Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville

Journal articles

Let’s start with a simple analogy: if a person eats more than they need, they gain weight. That is: if our feed inputs (kilojoules in) are greater than our outputs (exercise — kilojoules out) then we will gain weight (kilojoules in storage).That’s our fat. If, on the other hand, our feed inputs are less than our outputs, then we will lose weight.And if our inputs are the same as our outputs, our weight will remain constant. In general, the further away you are from an ‘ideal’weight, the greater the health risks. And yes, other aspects of your body management — …

The Role Of Eicosanoids On Nodulation Reactions To Bacterium Serratia Marcescens In Larvae Of Ostrinia Nubilalis, Hasan Tunaz, Ali̇ Arda Işikber, Mehmet Kubi̇lay Er

Turkish Journal of Agriculture and Forestry

Nodulation is the first step of the cellular defense reactions to bacterial infections in insects. In the present study, injecting larvae of the European corn borer, Ostrinia nubilalis, with eicosanoid biosynthesis inhibitors, immediately prior to intrahemocoelic injections of the bacterium, Serratia marcescens, sharply reduced the nodulation response to bacterial challenges. Separate treatments with specific inhibitors including dexamethasone (a phospholipase A_2 inhibitor), indomethacin (a cyclooxygenase inhibitor) and phenidone (a dual cyclooxgenase/lipoxygenase inhibitor) also impaired the ability of European corn borers to form nodules in reaction to bacterial challenges. The inhibitory influence of phenidone was apparent within 30 mins after infection, and …

Influence Of Three Soil Types On The Physical, Chemical, And Organoleptic Characteristics Of Two Varieties Of Kidney Tomato Hydroponically Cultivated Under A Panqar Huyu System, Carlos Fernando Yepez Vallejo

Theses and Dissertations

One of the largest problems that face communities located high in the Andres Mountain range is the lack of crop diversity due to the climate characteristics of this zone. Because of this, the Benson Institute created a small subterranean greenhouse called a "panqar-huyu," which in Aymara means "flower garden," that allows cultivation of small and medium-sized crops. This study's objective is to modify and adapt this system to cultivate table (kidney) tomatoes, for which one was enlarged, a drip irrigation system was installed, channels were dug to drain groundwater from the interior, etc. This study was done in the community …

G03-1512 Establishing Conservation Plantings Of Nut Trees And Shrubs By Direct Seeding Methods, Steven D. Rasmussen, Scott J. Josiah, John Wilson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to plant and raise nut trees and shrubs from seed. Seeding methods, planting design, site preparation and post-planting care are discussed.

Conservation tree and shrub plantings create wildlife habitat, improve water quality, produce marketable nuts, and enhance landscape diversity. Usually, nursery-grown seedlings are used to establish these plantings. However, a number of problems exist when using seedlings, including increased costs and reduced initial tree vigor and survival. Direct seeding of tree and shrub seeds avoids many of these problems, and is a proven, effective means to establish conservation plantings in Nebraska and elsewhere.

Ec03-1569 Grasshopper Identification Guide For Cropland Grasshoppers: Summer Feeding Species, Ronald C. Seymour, Gary L. Hein, John B. Campbell, James A. Kalisch

University of Nebraska-Lincoln Extension: Historical Materials

Summer feeding grasshoppers can cause severe damage to nearly all crops when they are abundant in field borders. Identification of the grasshoppers present is important because only four species are likely to cause significant crop damage. These four species are spur-throated grasshoppers that have a rounded head and a spur between their front legs. They are more common in weed-infested field borders and weedy adjacent pastures, but will move to cropland after consuming most of the weeds. Summer feeding grasshoppers overwinter as eggs and hatch through much of May and June.

Ec03-1568 Grasshopper Identification Guide For Rangeland And Pasture Summer Feeding Species, Ronald C. Seymour, John B. Campbell, Gary L. Hein, James A. Kalisch

University of Nebraska-Lincoln Extension: Historical Materials

Many kinds of summer-feeding grasshoppers are found in Nebraska rangeland and pastures. Of these, the six species listed in this guide are most likely to be numerous during outbreak years. These species overwinter as eggs and hatch through much of May and June. When abundant they can cause severe damage to rangeland and pastures, especially when dry conditions limit grass growth. Identification of the species present is important because some have greater potential for damage than others.

G03-1523 Low Toxic Cockroach Control, Barbara P. Ogg, Clyde L. Ogg

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to identify common cockroach species, what they need to survive, and effective, low-toxic alternatives to traditional chemical control options.

Some people see a cockroach and immediately grab a can of bug spray, but a quick spray from an aerosol can won't provide long-term control. Ingredients in most aerosol and "bomb" treatments repel cockroaches. Using these products can cause the cockroaches to hide deeper inside walls and be more difficult to control later. To make the most of your efforts to control cockroaches, use a multiple tactic approach. First, you need to understand a little about the …
