Influence Of Fertilizer Rate On Swollen Stem Formation (“Bulbing”) And Vitamin C Content In Different Kohlrabi Cultivars, Mark Iradukunda, Paul E. Read

Honors Theses

Kohlrabi (Brassica oleracea Gongylodes Group) is a vegetable crop found in the Brassicaceae, and it is rich in antioxidants such as vitamin C. Vitamin C helps in oxidative damage repair and strengthens the immune system, so exploring vitamin C sources may contribute to improving human health. The objective of this study was to determine the effect of different fertilizer rates on kohlrabi yield, in terms of the swollen stem and the vitamin C content, and if those effects are similar in different kohlrabi cultivars. In this greenhouse study, we fertilized four potted kohlrabi cultivars with a common water-soluble greenhouse fertilizer …

Ento 403/803: Management Of Horticultural Crop Pests—A Peer Review Of Teaching Project Benchmark Portfolio, Thomas J. Weissling

UNL Faculty Course Portfolios

ENTO 403/803, management of horticultural crop pests, is an important class for many students. It is required by undergraduate horticulture majors at UNL, but because it is offered online, it is also of interest to entomology and horticulture graduate students across the U.S. and globally. I chose this class for the peer review process because I find it challenging due to online course delivery, and the breadth of knowledge of students that are enrolled. I feel I need to take this course to a higher level where I can engage students of all backgrounds, and ensure that each of them …

Nf04-607 Growing Scallions (Green Onions) For Market Gardeners, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

Growing scallions (green onions) can provide market gardeners with early cash flow and customers with quality increases in storage life, freshness and flavor. Growing quality scallions is easier than growing quality bulb onions simply because they are in the field for a shorter time and bulb formation is not an issue when growing true scallions.

This NebFact discusses choosing and growing scallions from seed, fertilizing, the use of pesticides and herbicides for controlling pests and weeds, and a listing of seeding companies.

G03-1518 Chip Budding: An Old Grafting Technique For Woody Plants With Rediscovered Advantages For Nebraska, William A. Gustafson, T.M. (Todd) Morrissey

University of Nebraska-Lincoln Extension: Historical Materials

Chip budding is one of the primary grafting methods used for the asexual propagation of woody plants used to produce named cultivars (varieties) or clones of many ornamental trees, shrubs, fruit and nut trees. It is one of the two most popular budding systems used in nursery production, and it is the only budding system that can be done on rootstocks (stocks) that have either active or dormant vascular cambiums.

This NebGuide explains how to perform the technique and lists which plants can be successfully chip budded.

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.

Nf03-582 Early Season Extentstion Using Hotcaps, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

Hotcaps are covers used to protect individual plants from low temperature stress early in the season. There are three common hotcap designs: opaque plastic milk jugs, waxed paper, and plastic water-filled tubes. They are usually used by home gardeners or market gardeners with limited production. Growers with more acres or more extensive production tend to use row covers or high tunnels that protect more than one plant.

This NebFact discusses the study methodology, findings, and conclusions to using hotcaps in the garden.

Ec02-174 Noxious Weeds Of Nebraska: Leafy Spurge, Robert A. Masters, Brady Kappler

University of Nebraska-Lincoln Extension: Historical Materials

Leafy spurge is an invasive weed that infests over three million acres in the northern Great Plains and the prairie provinces of Canada. It is commonly found in rangelands, pastures, roadsides, rights-of-way, and woodlands. Leafy spurge can reduce rangeland and pasture carrying capacity by as much as 75 percent because it competes with forages and cattle avoid grazing areas infested with this weed.

This Extension Circular discusses the biology, identification, distribution and control of leafy spurge.

G98-1363 Container Gardening (Revised September 2004), Anne Streich, Kim Todd, Kelly Feehan

University of Nebraska-Lincoln Extension: Historical Materials

Container gardening has many advantages. People with physical limitations may appreciate the ability to garden without bending over or kneeling. Container gardens can also bring the garden closer to one's home or outdoor living area, such as along a sidewalk that is accessible from a wheelchair. Container gardens can place culinary herbs close to the kitchen to be snipped and used in cooking. Container gardens on patios or decks give people with limited outdoor space, such as an apartment and townhome dwellers, the opportunity to enjoy plants.

Growing flowers, vegetables, and other plants in containers provides many gardening opportunities to …

G96-1362 Soil Temperatures And Spring Planting Dates, Steven J. Meyer, Allen L. Dutcher

University of Nebraska-Lincoln Extension: Historical Materials

Dates on which soil temperatures reach a threshold value are presented as a spring planting guide for agronomic and horticultural producers.

For a seed to germinate it must have good contact with the soil and be placed in a favorable soil environment. A good soil environment is one that has suitable soil temperature, adequate soil moisture, good aeration, and for certain seeds, light. Conditions necessary for germination depend on the species and variety of seed being planted. Alone, none of these factors guarantee germination; rather it is the interaction of these factors that affects seed germination.

In Nebraska, soil moisture …

G98-1343 Fall Vegetable Gardening, Dale T. Lindgren, Susan D. Schoneweis

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the possibilities for and needs of a fall garden.

Though often overlooked by the gardener, planting vegetables in July and August for fall production is an excellent practice. Late plantings of cool- and warm-season vegetables can extend the harvest long after spring-planted crops have ceased production. Most cool-season vegetables grow as well as or better than those planted in the spring as they mature during shorter, cooler days. Flavors of vegetables maturing in the cool, crisp days of autumn are often sweeter and milder than those grown during hot summer weather. This is especially true for cole …

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide includes a plant list for shade landscapes.

While some may think of shade as a deterrent to gardening, it can be an asset if the special needs of shade-loving plants are considered. There are also ways to reduce the amount of shade, allowing more sunlight and air circulation into the landscape. To solve shade garden problems, shade's positive and negative aspects need to be considered.

G97-1315 Composting Manure And Other Organic Residues, Bahman Eghball

University of Nebraska-Lincoln Extension: Historical Materials

Composting is becoming more common in Nebraska because of the many advantages it offers. This NebGuide provides information on the composting process and its management and related issues.

The Composting Process

Composting is the aerobic decomposition of manure or other organic materials in the thermophilic temperature range (104-149°F). The composted material is odorless, fine-textured, and low-moisture and can be bagged and sold for use in gardens, or nurseries or used as fertilizer on cropland with little odor or fly breeding potential. Composting improves the handling characteristics of any organic residue by reducing its volume and weight. Composting can kill pathogens …
