This study investigated the effects of indoor horticulture activities on the current psychological well-being of older people in two long-term care facilities over a 7-week period. Thirty-one participants at one facility served as the control group. Thirty-one participants at another facility served as the horticulture group. Participants in both facilities continued with their normal daily routine and activities over the 7-week period; however, the horticulture group participated in a 1-hour horticulture activity session once a week over the 7-week period and the control group did not. The control group and horticulture group did not differ significantly in psychological well-being prior to the start of the study. After the 7-week program, the horticulture group had a significant increase in psychological well-being, whereas the control group had a slight decrease in psychological well-being. The results of this study indicate that horticulture activities may have a beneficial effect on the current psychological well-being of older people in a long-term care facility.

The Southern Horticultural Laboratory evolved from the USDA Small Fruit Research Station located at Poplarville, MS. A short history of the research facility and present horticultural research directions will be discussed. Emphases will be on past and present cooperative regional research efforts in horticultural crops.

Development of a business plan, facility development, and phased expansion for a multi-faceted horticulture operation will be discussed. The company, The Shepherd's Field, presently consists of fruit and vegetable production distributed through farmers' markets. The owner wants to expand the operation to include bedding plant production, also to be sold at farmers' markets. The objective of this project was to develop a case study for use in greenhouse management courses that would facilitate making management decisions. The present owner has limited resources available. Through researching facility and system costs, the case study will present the owner and students with choices to be made on the development and expansion of the facility. Ultimately, both the owner and students will make decisions. The process of case development will be discussed and the case presented.

The State Of Illinois passed legislation banning landscape wastes deposition in land fills. Approximately 18% of all solid wastes going into Illinois landfills were landscape wastes including grass clippings, branch prunings, leaves and wood. A cooperative program between the Horticulture Department, the Cooperative Extension Service and the Illinois Department of Energy and Natural Resources was initiated to train county extension advisers, municipalities, and the consuming public on methods for landscape waste reduction and recycling.

Workshops, video tapes, Master Composters, mobile displays, fact sheets and a model municipal composting facility were developed. Publications and other educational materials will be displayed.

Horticultural enrollments have fallen since the late 1970's and faculties are scrambling to find new ways to creatively finance educational and outreach programs. The Stephen F. Austin State University Arboretum was sanctioned by the administration in March, 1987. Eight acres of land that lie on LaNana creek are directly associated with the Agriculture building and horticultural facility. Gardens that feature a wide range of rare, unusual, and untested landscape plants are being developed by students, volunteers, and a mix of outside monies. The history of a City/SFASU project to develop a three mile LaNana Creek trail will be described. A cooperative effort with the Herb Society of Deep East Texas, a 121-acre conservancy easement project, and Asian vegetable studies are currently under the arboretum umbrella.

An inexpensive system for monitoring and controlling relative humidity (RH) above 90% and for monitoring temperature was developed and tested in a storage research facility for horticultural crops. A general-purpose IBM-PC microcomputer connected to an analog/digital interface system allowed for 16 differential analog inputs and 12 digital outputs for monitoring temperature and RH in eight storage rooms. Relative humidity, measured at 2-min intervals by an inexpensive wet/dry bulb psychrometer in each room, was regulated by a cool-mist humidification system. The standard deviation of RH from set-point was ± 2.8% at 2C and ±3.1% at 10C dry bulb temperature. The software. written in BASIC, allows for additional upgrading to meet future requirements. Commercially available components were used to construct the system at a cost of about Cd$1400 (Canadian) (microcomputer and cool-mist humidification system excluded).

At the Pennsylvania State University (Penn State) High Tunnel Research and Education Facility, a system of production of high-value horticultural crops in high tunnels has been developed that uses plastic mulch and drip irrigation. The Penn State system involves small-scale, plastic-application equipment that prepares and applies plastic mulch and drip-irrigation tape to individual raised beds. It differs from the production system developed by researchers at the University of New Hampshire in which drip-irrigation tape is manually applied to the soil surface and then the entire soil surface in the high tunnel is covered with a black plastic sheet. An overview of the production system used in the Penn State high tunnels is presented in this report.
