W. H. Gabelman


Warren H. Gabelman was born on April 18, 1921, in Tilden, Nebraska. Following graduation from Tilden High School in 1938, he entered the University of Nebraska, where it was his good fortune to have Professor H. O. Werner as an advisor and an employer. Professor Werner conveyed the “excitement of discovery” and the importance of a strong philosophy of research, which became building blocks for the professional career that developed. Sports were also important. He was an outfielder on the varsity baseball team for 3 years. It was at the University of Nebraska that he met his wife, Alberta.

This presentation focuses on driving forces and philosophies in the current Age of Accountability and explores ideas of how to respond. The increased scrutiny faced by all public agencies is requiring that Cooperative Extension approach the issue of accountability a bit differently. We must articulate our objectives and values to specific clientele groups, the general public, and government officials. Hard questions are being asked about past and anticipated return on tax dollars invested in state and federal agencies. The Government Performance and Results Act of 1993 requires “performance based budgeting” for all federal agencies, including the USDA. Each federal agency must develop an action plan with well-defined objectives and anticipated impacts to justify the allocation of federal funds. The overriding theme is not how busy we are and how many activities we can report, but what has been the impact of our efforts.

Foliar applications of urea nitrogen (N) is a relatively new practice in Florida citrus production resulting from applied research and changes in citrus fertilizer management philosophy. The present study investigated the effect of leaf age and surface morphology on leaf wettability as measured by contact angles, and absorption efficiency of foliar-applied N. Young leaves (0.25 and 1 month) were more efficient than old leaves in the absorption of foliar-applied N. Contact angles of water, urea-, and triazone-N solutions were low in the young leaves. The adaxial surfaces had lower contact angles than abaxial surfaces in each leaf age group. Inefficient N absorption and large contact angles in old leaves (3 and 6 months) were related to surface wax deposition and cuticle thickness, which increased with leaf age. 15N- and 14C-labeled urea are being used to determine precisely how the cuticle and wax affect foliar N absorption in citrus leaves.

The experience and resources of extension specialists can be used in academic teaching programs within a horticultural managers' seminar for advanced undergraduate students, drawing on production, marketing, sales, and distribution managers to discuss application of horticultural principles in work situations and other complex issues facing agricultural managers. Guest speakers present an overview of their background, work responsibilities, management philosophy, and management practices. Students interact with speakers in this informal seminar and complete written evaluations of speakers and topics for discussion in later classes. This horticultural managers' seminar exposes students to the medley of problems and opportunities facing agricultural managers, uses the resources of extension faculty in academic teaching programs, and reinforces ties between commodity departments and their respective industries.

A one-credit course, Writing in Horticulture, was developed and taught to graduate students in the Dept. of Horticulture at Clemson Univ. The course focused on discussion and explanation of the philosophies and methods of writing in the horticulture field. Discussions included a review of writing mechanics, types of writing and audiences, examples of exemplary writings, editing and reviewing, and examples and methods of professional correspondence. Real-life writing experiences were emphasized. Hands-on activities included writing and reviewing peer manuscripts and grant proposals. Three original written works were completed by the end of the semester: 1) a popular press article, 2) a grant proposal (maximum three pages long), and 3) an abstract for a manuscript published previously in a scientific journal.

International travel and study courses for undergraduate students can be significant academic learning experiences if there is a well-defined curriculum and high expectations for student performance on homework exercises, class discussions and evaluation instruments. An interdisciplinary perspective serves to broaden students' understanding. “In the English Landscape” is a three-credit, 4-week undergraduate course in-residence, primarily in Corsham, Wiltshire, U.K. Students explore the history of English landscapes and gardens in the context of post-medieval British history. The course is team-taught every other year by Purdue faculty from the Horticulture, History and Landscape Architecture programs. Excursions to landscape, garden and cultural sites provide the primary basis for student discovery. Pretravel readings and lectures prepare students for in-country, site-specific worksheets and class discussions. Course philosophy, content, structure, logistics, and instructional materials, which may be useful as a basis for course development by educators at other institutions, are presented.
