Category #1 - Select 1 course

HORT 824 Plant Nutrition & Nutrient Mgt.

This course will focus on the macro- and micronutrient elements and their function in the growth and development of plants. Emphasis will be placed on the uptake and transport of mineral elements from the soil into and throughout the plant, the role of single elements, interactions/balances between elements, and nutrient deficiency/toxicity symptoms as they affect the physiology of the whole plant. Pre-requisites include: plant physiology, soil, organic chemistry or biochemistry. Strong plant science/biology and algebra background are highly recommended.

3 UNL Dr. Ellen Paparozzi Spring - Even Years

HORT 842B Plant Physiology

Presents fundamental concepts underlying the science of crop physiology, including crop phenology, canopy development and light interception, photosynthesis and respiration, and dry-matter partitioning.

3 UNK Dr. Paul Twigg Fall - Even Years

HORT 842J Water Issues in Lawn & Landscape

Examines critical water issues related to irrigation in urbanizing watersheds, with an emphasis on water quality and quantity.  Factors impacting water scarcity and quality will be discussed.  Course will help students understand the interrelatedness of correct irrigation practices and water quality/quantity, and will equip them with the necessary career tools to help protect water resources through applicationof science-based irrigation practices. 

3 KSU Dr. Dale Bremer Spring (Not scheduled for spring 2017)

Category #2

HORT 843K Advanced Arboriculture

Course focuses on the physiological principles and industry practices in the production, moving, care, and maintenance of ornamental trees, shrubs and ground covers. The purpose of this course is to provide students with the career tools to install and maintain woody plants. This goal will be accomplished through the review of the pertinent literature and through class exercises designed to improve students' skills and knowledge of woody plant physiology, care and maintenance.

3 TTU Dr. Cyntia McKenney Spring - Even Years

Electives: Minimum of 6 hours required.  Select from the Following Courses:

HORT 814 Turfgrass Disease Management

Course focuses on diseases of grasses maintained as turf, emphasizing diseases that occur in the northern Great Plains of the U.S. In addition to strategies used in managing the diseases, the biology of the causal organisms and the influence of environmental conditions are examined.

1 UNL Dr. Gary Yuen Spring

HORT 843J: Herbicides & Weed Management Systems

The overall objective is to familiarize advanced students with the current state of knowledge on herbicide modes and mechanisms of action and recent developments by industry and universities in herbicide physiology. In this course, we will integrate plant anatomy, plant physiology, biochemistry, plant breeding, and principles of weed science as they relate to herbicide modes and mechanisms of action. This course is designed to examine how a herbicide molecule is absorbed (uptake) by plants, how it moves within plants (translocation), how it acts within plants (mode and mechanism of action), and the importance of metabolism as a means of selectivity between crops and weeds. This is not a course about weed identification, weed control recommendations, and weed management systems using biological, cultural, and chemical means.

4 TTU Dr. Peter Dotray Spring - Even Years

HORT 844B Environmental Stress Physiology

Physiology of plant responses to environmental stresses, with emphasis on current research in selected physiological, molecular, and biochemical mechanisms for tolerance to environmental stresses such as temperature extremes, drought, salt, pathogens and other plants.

1 NCSU Dr. John Williamson Spring

HORT 888 Business Management of Ag. Enterprises

Students will research a specific agricultural enterprise, then develop and present a business plan using materials from the primary area of interest. Requires the completion of a shadowing assignment and the analysis of case studies. *Please note that while the course is offered by UNL in both the fall and spring semesters every year, it is available through the special AG*IDEA enrollment system only in the fall of odd-numbered years. Please register with Diane Wasser, dwasser1@unl.edu, to receive the AG*IDEA tuition rate.

3 UNL Prof. Dave Lambe Fall, Spring*

HORT 843M Weed Science

In this course students will study weeds and weed control methods in agronomic and horticultural crops and turf grass with an emphasis on chemical weed control. The course is divided into lecture and laboratory sections. The lecture portion will count three-fifths (3/5) of your total grade and the laboratory will count two-fifths (2/5). In lecture, we will discuss the history of weed control, weed characteristics, weed competition, and methods of weed control including mechanical, cultural, biological, and chemical. Herbicides will be discussed by family with specific regard to their chemical structure, efficacy, mode and mechanism of action, crop selectivity, soil activity and persistence, and cost. In lab, we will examine the practical aspects of weed control including weed seed and plant identification, sprayer equipment, sprayer calibration, herbicide formulations, herbicide labels, crop/weed response to herbicides and injury symptomology, and Worker Protection Standards

4 TTU Dr. Peter Dotray Fall - Odd Years

HORT 880 Modified Rootzones

Modified rootzones and their applications in the turfgrass and landscape management industry. Correct applications and construction techniques.
