Brief Summary of Minutes of Annual Meeting

OBJECTIVE 1. To integrate environmentally acceptable and economically profitable management models (decision-support) into controlled-environment plant-production systems:

(a) To develop decision-support tools based on plant growth and development models to enhance crop growth control and profitability

AZ defined growth patterns for tomato cv. Rapsodie for arid and semi-arid climates, which indicate the tendency for vegetative or reproductive development when subjected to different vapor pressure deficits regimes and nutrient solution electro-conductivity (EC), under constant temperature and light conditions. Uptake dynamics for ammonium, nitrate, potassium, magnesium, etc. were monitored for sweet potato in hydroponic solutions. Sweet pepper crop production under high light, high temperature, low humidity, desert conditions was compared within two greenhouse production systems; a traditional polycarbonate covered structure with computerized environmental control and data acquisition system; and a retractable-roof polyethylene covered structure with a low cost heating and environmental control system.

CT (CTNH) studied the response of greenhouse tomato to supplemental nitrogen and potassium. Yields were compared for plants grown in rock-wool medium with sufficient nitrogen and potassium, or with N- and/or K-supplements that increased the concentrations in nutrient solution by about 30% during fruit production. There were few specific effects on yield or fruit size due to supplemental nitrogen or potassium, except ammonium nitrate altered calcium and potassium distribution in the plant and increased blossom end of the fruit. All other effects could be ascribed to changes in solution EC within the root medium. A greenhouse tomato cultivar trial in 1999-2002 compared characteristics for 21 cultivars of greenhouse tomato when grown using rock-wool, an inert root medium used in hydroponics. Cabernet, an open-pollinated beefsteak cultivar, had the highest total yield, but four other beefsteak cultivars had yields indistinguishable from Cabernet. Fruit size varied from 212 grams for Nicklow 102, down to about 85 grams for Cronos and Dynamo. Quest, a beefsteak type, had the best yield of marketable fruit, nearly 10 kg/m2, followed by Buffalo, Match, Mississippi and Trust. Most cultivars had a marketable yield in the range of 6 to 8 kg/m2. Cronos and Tradiro were the only cluster types with similar marketable yields.

KY tested a dynamic mist propagation system in a greenhouse based on a model accounting for net radiation, air temperature, VPD, canopy resistance and water uptake was compared with a static mist control. Depending upon environmental conditions the dynamic controller used 35% less water and poinsettia cuttings had larger roots and greater root length. The dynamic system had less runoff and less water was contained in the growing medium. Heating tests for poinsettia propagation under varying aerial environments showed the optimal root zone temperature range changed as roots developed. The system allows model-based feedback control, as well as standard control techniques. The controlled water table automatic irrigation system was improved by replacement of round PVC nutrient supply trough with an aluminum rectangular trough. The narrow profile reduced bench width and eliminated potential dripping. Placement of the trough in the center, rather than the side of the bench, and capillary mat products were evaluated. Tests were initiated to utilize two separate water tension set points for simulating a wet-dry cycle

MI (with Hiroshi Shimizu at Ibaraki University, Japan) developed a model to simulate plant shoot-tip temperature of poinsettia using an energy-balance equation based on five greenhouse environmental factors: dry-bulb, wet-bulb, and sky temperature; transmitted shortwave radiation; and air velocity. The model is more effective than dry-bulb temperature at predicting plant shoot-tip temperature when solar radiation is moderate to high. The effects of temperature and light quantity were measured on growth and development of several bedding plant species, and their interaction to control flower timing, flower number and size, dry weight, and other growth factors at the plug stage (from seed sow to a mature transplant) and at the finish stage (from a mature transplant until first flowering). Vernalization responses for a number of herbaceous perennial species were measured when plants were cooled to -2.5 to 20 oC for various durations.

NH enhanced a software package for graphically tracking height of potted flowering plants, UNH FloraTrack, available at (http://www.ecke.com/new1/poin/points_tech_graph_track.asp), to allow users to enter their own target optimal growth curve modified to their own growing conditions and market specifications. In collaboration with North Carolina State Univ., NH examined optimum production and post-harvest conditions for Renaissance Red cut flower poinsettia. Profitability compared favorably with potted poinsettia. A maximum vase life of 20.6 days was achieved. NH in collaboration with OH assembled greenhouse nutrition research into an overall extension program for pH management to quantify dynamics of root media pH and develop a quantitative model of pH change and micronutrient uptake in soilless media.

NJ studied tomato responses to short-term environmental perturbations. Tomatoes (cv. Laura) grown in 6 pots filled with perlite were pruned to maintain a single cluster. The perturbation was a two-week air temperature change (1 50C from the control day/night air temperature of 230C/180C) starting at ten days post fruit-set. The temperature disturbances had a dramatic impact on fruit maturity rate. In 2001, a mail survey of greenhouse operators in NJ was completed. A follow-up survey was prepared this spring, and results are being tabulated. A greenhouse cost accounting Excel spreadsheet is now available which allows greenhouse owners to determine the costs and returns of individual crops.

NY developed a model of lettuce evapotranspiration for a computer-based fault detection system. A second model predicted nitrate uptake in stressed and unstressed lettuce. An analytical solution was found to the general problem of optimizing the daily light integral target and the carbon dioxide concentration, with consideration of infiltration/ventilation. A computer control algorithm is currently being developed to improve energy efficiency and cost effectiveness of using supplemental lighting for greenhouse lettuce production.

OH developed a top-level overall Advance Life Support Systems model to integrate the subsystem models of Crew, Biomass Production, Food Processing and Nutrition, and Waste Processing and Resource Recovery to support human lives during long duration space exploration missions. Guidelines for commercial rhizofiltration systems to remove heavy metals from contaminated waters were developed from a process model based on the Michaelis-Menton equation, to quantify accumulation and removal of toxins within the rhizofiltration system. A Dehumidification Decision Support model for Disease Pressure Management in Greenhouses was an effective alternative for non-chemical management of pests in greenhouses. A greenhouse irrigation control system improved Water Use Efficiency based on non-contact infrared thermometry of plant canopy temperature to determine plant stress. Compared to the control, 41% less water was used for the integrated CWSI feedback approach. Control and treatment crops had no significant difference in growth.

PA Cut flower production of platycodon, dianthus, snapdragon, and larkspur planted into high tunnels was compared to cut flower production in the field. Platycodon did not do well in the high tunnel and did not survive in the field. Cut flower production of the 3 other crops were good. By July 5, Dianthus produced about 10 times more flowering stems in the high tunnels than the field, snapdragons produced 5-7 times more flowers, and larkspur produced 4 times more cut flowers in the high tunnel than in the field, due to earlier flowering by 2-4 weeks.

(b) To develop an integrated information database on CEA plant growth systems to facilitate analysis and to produce a decision-support tool.

OBJECTIVE 2. To enhance commercial greenhouse design, water management, and environmental systems for cool and cloudy climates:

(a) To develop design and control recommendations for naturally ventilated greenhouses.

AZ evaluated water use by greenhouse tomato plants under controlled micro-environmental conditions and evaluated the magnitudes of the radiant and convective energy sources contributing to plant water use.

NJ completed construction of an Open-roof greenhouse (Van Wingerden, MX-II, four gutter-connected bays, 17.7 by 18.3 m floor area, 4 m to the gutters, 2 independently controlled growing areas of 7.3 by 13.7 m). Experiments investigated: natural ventilation system, floor heating system, and ebb and flood floor irrigation system. Significant temporal changes in light intensity were observed under full sun or when light passed through one or two layers of roof sections. Six high tunnels were constructed at two research sites in Central and South Jersey. Temperature, humidity, and light sensors were mounted inside and outside the tunnels to monitor environmental conditions. Two of the tunnels were outfitted with thermostatically controlled automatic roll-up sides to determine the effectiveness of this control system.

NY researchers provided the natural ventilation computer model and recommendations for ventilation of the Palm House and Garden Court of the U.S. Botanic Gardens. The leader of the tour of the facilities, that was part of the NE-164 2003 annual meeting, emphasized the good environmental control afforded by the system as installed.

OH, in partnership with two Spanish researchers with gas diffusion data from a Spanish Parral greenhouse used Computational Fluid Dynamic Modeling to examine turbulent models and the effect on output. Under certain wind speeds and opening arrangements, there was little difference between the standard k-epsilon and the RNG k-epsilon. However, for leeward roof opening at certain wind speeds, there was a major difference between the two model results. The verified models were used to modify and manage the natural ventilation to increase in air exchange from increasing the roof opening, increasing the roof slope, and adding sidewall openings.

(b) To enhance technology transfer and research in artificial lighting.

AZ is evaluating hybrid solar and electric lighting for plant biomass production, utilizing fiber optic cable for delivering solar energy within an enclosed plant growth facility

NH and MI collaborated in organizing a book and magazine series on light management for greenhouses that will draw together research from several NE-164 members and other researchers for use by growers and students. Publication of the magazine series will begin in 2003.

NJ The economic benefits of supplemental lighting for plug production were studied during a two-year collaborative research project with Paul Fisher at NH.

NY cooperated with a leading developer of environmental control software for agricultural applications to implement and test a supplemental light control algorithm at a NY facility. It shows a high level of control accuracy comparable to that obtained by simulation during development of the algorithm.


(c) To improve greenhouse wastewater treatment through the use of constructed wetlands, or phytoremediation.
