Science In Early Childhood Education, Olivia Kocina

Capstone Projects and Master's Theses

Science is often limited or absent in an early education classroom. It is important to give children an outlet to experience science in the classroom or through lesson plans. Having science at an early age can provide children the opportunities to build up their reasoning, to question things about the world, and later in life to feel more confident in other STEAM (science, technology, engineering, art, and math) activities or areas. To address this need, I created a 3-day program for 3 to 5 year-olds at Little Learners of Aptos School in Aptos, California.

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

Laurie Hodges

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.

G92-1123 Spinach And Swiss Chard, Laurie Hodges

Laurie Hodges

This is a guide to the growing, harvesting and use of spinach and swiss chard. Spinach Spinach is a cool season crop and belongs to the goosefoot family (Chenopodiaceae), along with Swiss chard and beets. Spinach is low in calories. It is a good source of vitamin C, vitamin A, and minerals, especially iron. After washing the leaves, cook them in a covered pan using only the water clinging to the leaves. After cooking, add salt and butter, vinegar, or mustard for added flavor. Spinach may be prepared in a souffle, creamed soup, or used raw in salads. Swiss Chard …

Calligraphy As A Developmental Tool For Chinese Painting, Jo Lan Shu

Theses and Dissertations

This report discusses the design, development, and evaluation of a Chinese painting instructional project. The project discussed in this report introduces the novel idea of developing specific calligraphy skills in order to improve Chinese painting skills within a restricted time period (1-3 hours). The results show differences that are statistically significant between the pre and post test paintings created by 23 subjects from both the high school and the university level. The results of the evaluations can be found in the results section of this report. This report consists of a literature review, a project description, a description of the …

Nf02-520 Fungicide Spray Schedule For Home Garden Small Fruits, John E. Watkins, Jernnifer L. Chaky

University of Nebraska-Lincoln Extension: Historical Materials

Home grown strawberries, raspberries and grapes are a rewarding experience for the gardener as well as the consumer of the fresh fruits and jellies. If properly managed, these crops can be a source of enjoyment for years. To be successful, however, the home gardener must develop a sound integrated pest management (IPM) approach to controlling diseases and insect pests. A good IPM program makes use of cultural, varietal and chemical means of preventing or reducing disease losses.

This NebFact discusses which fungicides to use for which disease of small garden fruits and provides recommendations for a fungicide treatment schedule.

Nf00-410 Fungicide Options For Managing Foliar Diseases On Wheat, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Stripe and leaf rusts, tan spot and Septoria leaf blotch comprise the four primary foliar diseases of wheat in the central Great Plains. In eastern and south central Nebraska leaf rust and Septoria leaf blotch are common, and in the wheat-fallow-wheat regions of western Nebraska, tan spot is an important foliar disease. Stripe rust occurs statewide.

This NebFact discusses the options of treatment criteria, profitability of treatment, treatment products and timing for managing foliar diseases of wheat.

Nf99-397 Gray Leaf Spot Of Perennial Ryegrass In Nebraska, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Gray leaf spot, caused by the fungus Pyricularia grisea, was reported in the early 1970s to be a damaging disease of annual ryegrass grown for forage in the southeastern United States. Forage yield losses were so severe that the disease was named ryegrass blast.

This NebFact discusses the diagnosis, future occurrences, and management of gray leaf spot in Nebraska and surrounding states.

G91-1060 Black Spot Of Roses, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Black spot, Nebraska's most troublesome rose disease, can be controlled through selection of a resistant cultivar, spaced plantings, and an active fungicide spray program.

Roses are one of the most versatile and inspiring ornamentals for landscaping. There are roses adapted for any garden site and landscape purpose. Roses are not always easy to grow and may require a little more management than other ornamentals. One of the greatest challenges to successfully growing garden roses is disease control.

G88-890 Pythium Blight Of Turfgrass, John E. Watkins, Robert C. Shearman

University of Nebraska-Lincoln Extension: Historical Materials

Causes, symptoms and treatment for pythium blight are covered here.

Pythium blight, sometimes called "grease spot" or "cottony blight," is no longer a disease of golf courses; it also is a serious problem in home lawns and other turfs. Caused by several species of Pythium fungi, the two most commonly associated with Pythium blight are Pythium aphanidermatum and P. graminicola. These fungi are in a group known as "the water molds," a group that includes Phytophthora and other pathogenic genera. They are referred to as "water molds" because they function best under wet, saturated soil conditions.

The Pythium species …

Ec78-1233 Pruning Fruit Trees, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Productive fruit trees with an abundance of high quality fruit don't just happen. They result from good cultural practices, including pruning. Pruning is often neglected either due to a lack of pruning skills and knowledge or a fear that one is going to injure or kill the tree.

A major requirement for the backyard farmer is a small tree open enough to allow effective spraying with home equipment and ready gathering of fruit. Pruning, combined with growing dwarf fruit trees will help accomplish this requirement. Although pruning is essential in development and maintenance of fruit trees, excessive pruning in young …
