Nursery management, a course covering practices involved in production of woody landscape plants, was developed for delivery to place-bound students at distant sites around the state. Course subject matter was divided into 41 modules and involved aspects of site selection, cost accounting, plant propagation, nursery trade associations, licensing, as well as container and field production practices. Each module began and ended with a 1- to 2-min introduction and summary to the subject matter, and these segments were taped on location at nurseries in the Pacific Northwest. The lecture portion of each module was taped in a multimedia classroom, and presentation software was used to present text, slides, drawings and animation. Videotape footage of some cultural practices was also inserted into lectures as a “field trip.” Students in the course also received a lecture note guide for all modules in the course. In Idaho, the videotapes were distributed to education centers around the state. The first time the course was offered, 11 students at distant sites and three time-constrained students on campus enrolled. Students contacted the instructor by phone or e-mail. Homework assignments were sent via FAX or e-mail attachments, and tests were sent to the education centers where proctors gave three exams and a final exam. All tests and homework assignments were graded by the instructor located on campus. A videotaped course in nursery management can adequately convey principles involved in landscape plant production, but logistics of mailing videotapes and grading assignments and tests should be carefully evaluated when deciding if a course should be offered at a distance.

Two commercially produced growth media made of light, low humified sphagnum peat, were used to determine how filling into containers affects the particle size distribution and water retention characteristics of peat. It was shown that the filling procedure used broke up the peat particles, resulting in a significant increase in the proportion of particles < 1 mm (g·g-1). Due to the increased proportion of fine particles, the water retention of the peat media increased under wet conditions (-0.1 kPa matric potential), while the air-filled porosity decreased to nearly 0. Also, at matric potentials lower than -0.1 kPa, the reduction in air-filled porosity may restrict aeration and availability of oxygen to roots, thus reducing growth of plants.

Progeny from two open-pollinated mother trees were grown for 1 year in a commercial tree nursery in Murphy, N.C. Shade cloths were applied to one half of the seed plots from each mother tree and the other half were exposed to full sunlight. Seedlings were fertilized throughout the growing season to increase growth performance for better discernment of progeny and shade effects. Seedlings in shaded plots were significantly taller and had larger root collar diameters (RCD) than unshaded seedlings. An interaction between progeny and shade effects on first-order lateral root number indicates that genetic or other unknown factors were affecting the seedlings' response to changes in light. Results indicate that the use of shade cloths in nurseries may improve seedling quality of 1-0 sugar maple in the southern portion of the species range.

This decision case concerns production and marketing problems that many ornamental growers incur. At the retail level, popular ornamental crops are often used as loss leaders to draw the public into stores to make other purchases. As a result, retail buyers are concerned not with quality but with price and volume. To meet the needs of price-conscious buyers, growers may attempt to reduce their production costs by reducing the level of production inputs, with some sacrifice in product quality. The owners of Two Sisters Greenhouses must decide whether they are going to produce lower-quality plants, change marketing strategies, or grow alternative crops to retain their current profit margins. This case study was intended for use in greenhouse management, nursery management, and floriculture courses where students assume the role of a decisionmaker in poinsettia production and marketing.

The Ohio State Univ.'s Agricultural Technical Institute is a 2-year institution within the College of Food, Agricultural and Environmental Sciences. For over 20 years the school on the Wooster campus has offered technical programs in ornamental horticulture and floriculture leading to the Associate of Applied Science degree. Enrollment in the programs of Floral Design and Marketing, Greenhouse Management, Landscape Contracting, and Construction, Nursery Management, and Turfgrass Management is near 350 students. During the past year, a new program was developed with the primary purpose of serving those students who wish to transfer into a baccalaureate program within the college. Students are granted an Associate of Science degree in Horticulture upon completion of the curriculum requirements at the technical college. Those following this track have a unique opportunity for exposure to two different learning situations. They can progress toward their goal without loss of credit. The curriculum allows students to explore several areas of horticulture before commitment to their specialty. Beginning students have the advantage of a small campus with an active learning assistance program.
