Brief Summary of Minutes of Annual Meeting

Brief Summary of Annual Meeting Complete meeting minutes are available at http://ncr101.montana.edu/meetings_past.htm Opening: Alex Turkewitsch called the meeting to order at 8:15 am and welcomes the members of the NE-1035 group. He also thanks Peter Vanderveer and Bob Morrow for organizing this meeting. Peter Vanderveer (local host) welcomed everyone to Madison, WI. Announcements: Upcoming meetings of interest include the 1st Meeting of the American Council for Medicinally Active Plants (Rutgers, 20-23 July 2010), GreenSys 2011 (Greece, summer 2011), and the upcoming lighting conference. Approval of 2009 Minutes: Jonathan Frantz presented the Minutes of the 2009 business meeting in Park City, UT. The minutes are available on the NCERA-101 website. Administrative Advisors Report: Richard Straub (University of Wisconsin), on behalf of Ramesh Kanwar, gives the administrative advisors report. He commends the group on holding a joint meeting with the NE-1035 group and recommends doing this periodically to tap into synergy between these two groups. He also announces that the NCERA-101 project expires in 2011 and needs to be renewed. The new project proposal to continue this project is due this fall. Several deadlines need to be met to renew the project. The most important deadline is December 1, 2010, when the complete proposal is due December 1. This is a hard deadline. CSREES Administrative Report: Dan Schmoldt was unable to attend and to give the CSREES Representative Report. John Lea-Cox makes some comments for Dan Schmoldt and mentions that there have been changes USDA. NIFA (National Institute for Food and Agriculture) is a new USDA institute. USDA hopes that NIFA will raise the profile of its research programs and that this will result in larger research budgets. Mandatory USDA spending is decreasing, with more money going to AFRI, USDAs large competitive grant program. Other programs are being rolled into AFRI. There likely will be more of an emphasis on large multi-institutional grants, with budgets of $5 - 10 million. The Specialty Crops Research initiative will remain as a separate program at least for next few years, while other programs are combined in AFRI. USDA has five new areas of emphasis: agricultural competitiveness, nutrition and obesity, climate change, food safety, and energy security. The expected 2011 budget for AFRI is expected to be $262 million, with a longterm goal of up to $800 million. All programs are going to be trans-disciplinary. John Lea-Cox then describers his experience with SCRI proposals, and mentions that matching issues can be particularly hard to deal with. Membership Report: Mark Romer presented the Membership Report (see meeting minutes for complete report). There currently are 150 members, from 104 institutions, 29 states, and 8 countries, with several new people attending this year. We now have a letter of invitation, which can be used to recruit new members/recruits for this group. The chair is responsible for sending these letters. If someone has a need for such a letter, contact Mark Romer or the current chair. Website Report: Mark Romer gives a brief history of the website, which was started by Dave Tremmel. The website has the groups history, as well as a separate page for each member, which can be updated by the members. The website has been expanded to include guidelines for growth chambers and tissue culture. The growth chamber handbook is on-line as well. The website was initially hosted by Duke, but transferred after Duke was no longer a national facility. Tracy Dougher (Montana State) took over web site at that point. She has been adding station reports and member information. A major upgrade was made several years ago to include the last international meeting at KSC and more history. Tracy Dougher has requested that we find someone to take over website. Mark Romer asks for volunteers to take over the website and Carole Saravitz at NC State volunteers. This gets approved by unanimous vote. The decision is made that the group will get its own domain name, ending in .org. The exact name will be determined later. Email/Electronic Discussion Group: Mark Romer than gives an update on Google Groups. This discussion group is currently functional, started in May 2009. 68 people signed up for this group as to date. There has been very little activity in this group. One of the problems is to make sure that people are aware of new postings. Currently the Google groups site is not very effective. Often postings to this group get e-mailed to the general membership as well, so there is a duplication of effort. Instrument Package Report: Bruce Bugbee gives the instrument package report and reviews the purpose of this package. It is a revolving instrument calibration package, and users should use it to calibrate their own sensors. There are four different packages available. Traditionally the cost has been $300/package, but it now has dropped to $100/package. Alec Hay administers the instrument package. The instrument package had a balance of about $477 one year ago, but the surplus from the KSC meeting has now been transferred into this account. The surplus from the Park City meeting also been added to account. The current balance is $13,792.22. International Committee on Controlled Environment Guidelines: A.J. Both mentions that this committee was started in 2001, to develop minimum reporting guidelines for growth chambers, which were completed in 2004. In 2004, tissue culture guideline project was started, and these were published 4 years later. In 2008, a suggestion made to start developing greenhouse guidelines. The goal is to have these guidelines in place for the 2012 meeting in the UK. This topic has been discussed at previous NCERA-101 meetings, as well as GreenSys 2009. At GreenSys, the decision was made that the outline at that point was too much focused on engineering and a new outline, with five focus areas has been developed. A.J. Both asks people to look at this outline and asks for people to volunteer to work on one of these five areas. New Business Committee Officers: The nominating committee (the executive committee) nominated Peter Ling (Ohio State University) for incoming secretary. No other nominations were voiced; Ray Wheeler motioned to accept the nomination, Dick Gladon seconded, and the appointment passed unanimously. Surplus Meeting Funds: Gary Gardner proposes that next years executive committee should present a proposal on how to use some of these funds to support the UK meeting and expresses the opinion that these funds should not be used to help plan our annual meeting, but rather as a buffer if a particular meeting has a shortfall. He also emphasizes that we would lose money without corporate membership. Alex Turkewitsch states that the executive committee will follow up on what to do with the surplus funds and look into funding opportunities to support travel to the UK meeting in 2012.. Future meetings: Mark Romer gives an update on the 2012 meeting and relays information he got from Lynton Incoll. They have booked a venue in Cambridge (Downing College) in East Anglia, which is easy to reach from London. The program will follow the format of 2001 meeting, with invited review talks, about 25 minutes long. There will be eight sessions with 20 speakers, who will cover the historic background of topics. There will also be poster sessions and a trade exhibit. The full scientific program still needs to be developed. Dick Gladon volunteers to host the 2011 meeting. They will have new greenhouses going up, which could be toured. His offer is accepted by the group. Cary Mitchell indicates interest at Perdue to organize the 2013 meeting, perhaps together with Dow AgriSciences. Adjourned: Meeting adjourned at 12:25 pm. Transfer of Chairmanship: The gavel was passed from Alex Turkewitsch to Jonathan Frantz. Graduate Student Poster Competition: The NCERA-101 2010 competition had four participants and was won this year by John Snider from The University of Arkansas. Prepared by Marc van Iersel, Secretary, April 20th, 2010.

NCERA-101 Accomplishments and Impacts (Complete station reports can be viewed on the NCERA-101 website) Agritechnove completed the new High Containment Canola Research Facility in Western Canada. A very high-tech facility that holds promises of very productive research. Agritechnove also completed several USDA projects throughout the country: theyre now open in Washington, DC, Fort Collins, Louisiana and Beltsville while more are awaiting construction in Geneva, Ithaca, California and other stations. Cornell University has developed a risk analysis model for hydroponic, baby-spinach production in deep-flow systems. Cornell University also quantified the effects of environmental control on the production of a useful industrial enzyme by genetically-modified and hydroponically-grown tobacco. Germination and plant spacing at Cornell University for baby-leaf spinach were found to provide optimum yield at a plant density near 1500 plants per square meter. Double-seeding half the cells in commercially available hydroponic floats was found to yield as much as single-seeding every cell, with significant savings of root medium. Kennedy Space Center found that the concentration of the bioprotective anthocyanin pigments were increased fourfold in lettuce cv. Outredgeous grown under red LEDs through selective application of blue or ultraviolet light. McGill University is researching in 2 target areas with the first focusing on identifying biofuel potential of corn stover and greenhouse heating using wood pellets. The second focus area is using proteomics as a means to monitor organism growth. Research is continuing in LED for plant production. Michigan State University has identified how light duration and quantity influence flowering of range of ornamental garden plants grown in greenhouses. This information is being used by greenhouse growers to improve their scheduling of crops so that plants flower on time. ORBITEC continues to develop solid state lighting systems for biological research applications. Systems have been developed for research, growth rooms, and greenhouses. Purdue University performed controlled-environment optimization studies of strawberry, sweetpotato, corn, and ornamentals emphasizing lighting, temperature, and cultural variables. Crop gas-exchange cuvettes were developed that will enable real-time photosynthetic rates to be correlated with LED lighting parameters as well as CO2 and temperature variables. Rutgers University exposed extension personnel and commercial greenhouse growers nationwide to research and outreach efforts through presentations, various publications and evaluation tools. It is estimated that this information has led to proper greenhouse designs and updated operational strategies that saved an average sized (one acre) greenhouse business a total of $20,000 in operating and maintenance costs annually. The University of Alaska-Fairbanks research activities address emerging local needs for energy efficient greenhouse and controlled environment production. Outreach efforts provide information and training opportunities to experienced growers as well as those with limited or a recent interest in commercial greenhouse production. The University of Arizona developed a low temperature storage method for grafted cantaloupe seedlings (up to four weeks) that would save labor requirement of grafting propagators significantly. They also developed a computer vision guided crop sensing and monitoring system and a methodology to monitor nutrient deficiency which could eventually save labor to monitor crop quality and yield, as well as improve resource use efficiency. Finally, they have designed and developed the ACCORDION photobioreactor for production of photosynthetic algae and plant cell, tissue or organ cultures. We have confirmed in green algae that growth and chlorophyll content can be significantly increased using the same amount of light energy by implementing a composite lighting profile. We will be testing a prototype for the spectral phytometric light meter, a four-in-one light meter that measures and reports radiation in phytometric, quantum, radiometric and photometric units. The University of Arkansas has continued to develop techniques to measure the effects of high temperature and water-deficit stresses in cotton flower pistils in controlled environment conditions. These studies have improved our understanding of the effects of high temperature stress on cotton reproductive development in order to explain the yield variability experienced by Arkansas farmers and facilitate the development of methods of amelioration for yield stabilization and enhancement. The University of Florida has characterized flowering responses of 30 long-day bedding plant cultivars under the night interruption lighting to reduce crop time and improve finish plant quality for spring production. Additionally, the use of limited inductive photoperiod of long-days for limiting the duration of lighting was evaluated. The University of Georgia developed a prototype irrigation and fertilization system that can automatically irrigate and/or fertilize based on the needs of the crop. By measuring the water and fertilizer content, a controller decides when a crop should be irrigated or fertigated, assuring that water and fertilizer applications are in concert with the crops needs. We expect that this approach can greatly reduce water and fertilizer applications, while improving crop growth and quality. The University of Maryland recommended that growth chamber manufacturers use new fluorescent TL841 lamps to retrofit chambers that currently utilize T12 cool white fluorescent lamps, based on light and plant growth research conducted at the University of Maryland. The University of Maryland developed a web-based Knowledge Center for Water, Nutrient and Plant Health Management to facilitate and disseminate up-to-date information about water and nutrient management strategies and tools to implement best practices in nursery and greenhouse operations. The site now has over 600 registered users. During 2009, 16,132 unique visits came from 160 countries and 49 states with 2,549 (17%) return visits from both registered and unregistered users. The University of Tennessee developed a web page was posted to disseminate research information on Controlled Environment Culture to commercial producers, and a blog was created to interact with growers and potential growers on design and operation of protected culture production systems The University of Wisconsin Biotron continues to incorporate the expanding Deluca research program for the duration (2-3 year) of the renovation of the Biochemistry building. This commitment has stretched their resources, staffing and slowed the conversion to the new control system. The patents held by this research program are the top royalty (~15mil/year) generator for WARF (Wisconsin Alumni Research Foundation). The USDA-ARS Crop Systems and Global Change Laboratory in Beltsville, MD conducted multiple experiments in growth chambers on effects of elevated atmospheric carbon dioxide concentration (CO2), nutrition, and water stress for several crops and varieties. A new technique for measuring leaf mesophyll conductance to CO2 in controlled environments was developed. The Ohio State University team is continuing the effort in developing a decision support tool to assess the potential of energy can be harvested from a greenhouse to reduce reliance of fossil fuel for heating and cooling operations. The USDA-ARS team in Toledo, OH released Virtual Grower 2.5 software; over 8,000 copies have been distributed since the original release of the software.

In addition to their efforts above, the NCERA 101 group had over 150 reports either published or accepted for publication since the last meeting.
