Brief Summary of Minutes of Annual Meeting

METHODS (please include your activities and accomplishments where appropriate):

 

Objective 1: To evaluate and develop strategies to improve energy efficiency in controlled environment agriculture

Planned Outputs:

1. Develop recommendations for optimal lamp choices and layouts for greenhouses and indoor production facilities

 

AZ (Arizona State University)

 

In ever-bearing strawberries, researchers at Arizona State University identified that sole-source lighting with a photosynthetic photon flux density of 300 µmol∙m^-2∙s^-1 or higher, coupled with a 16-hour photoperiod, resulted in superior plant growth, flowering, and fruit production. Additionally, adding far-red light in the sole-source lighting spectrum accelerated fruit harvest and increased fruit yield and brix value in the ever-bearing strawberry variety 'Albion'.

 

DE

 

The University of Delaware collaborated with Michigan State University on a peer-reviewed publication in the Journal of the American Society for Horticultural Science. This paper discussed a unique flowering response of chrysanthemum to light quality when grown indoors. The inclusion of far-red light, but not green light, in the main photoperiod is necessary for day-extension blue light to inhibit flowering in chrysanthemum grown indoors.

 

The University of Delaware and Michigan State University collaborated on and published a peer-reviewed publication in Plants. We found that the blue photon flux density in a broad spectrum determined growth and morphological responses of indoor hydroponic lettuce ‘Rouxai’ to broad spectra. Plants had increased biomass and extension growth, but less intense red coloration, under broad-spectrum LEDs fixtures with lower blue photon flux densities.

 

IN

Gómez conducted experiments evaluating intumescence response of susceptible vegetable plants grown under different light qualities from LEDs and in a glass-glazed greenhouse. She also evaluated different light intensities to propagate strawberry plants indoors.

 

NJ

 

We continue to evaluate a variety of lamps for light output, light distribution and power consumption using our 2-meter integrating sphere and a small darkroom.

 

We are also conducting research on the environmental impacts of plant lighting systems. We’re using life cycle analysis calculations to assess various lighting technologies and strategies.

 

NY

 

Cornell: Carbon dioxide supplementation is often used in hydroponics/aquaponics to increase photosynthesis and thereby yield/biomass while reducing the need for supplemental lighting. However, there is little information available on the impact of CO2 enrichment on human nutrition of leafy greens. Lettuce cultivars ‘Rex’ and ‘Rouxai’ were grown under CO2 concentrations from 400 (ambient) to 1600 ppm. Lettuce fresh weight increased with elevated CO2 concentrations with most of the benefit achieved by 800 ppm (20-28 percent yield increase) and further benefits of only 3-11% with CO2 increasing up to 1600 ppm. Regarding nutritional impact, ‘Rouxai’ exhibited a slight decline in violaxanthin (an antioxidant), but there were no significant differences in anthocyanins (antioxidant), lutein (eye-health pigment) or mineral content. Therefore, CO2 supplementation is an effective method to significantly increase yield for lettuce while having only subtle effect on nutritional components.

 

USDA-ARS

 

The USDA-ARS/Ohio developed and released a beta version of Virtual Grower 4.0.  Virtual Grower is a decision-support software tool that allows users to build a simulated greenhouse and estimate energy costs for various geographic locations, greenhouse designs, heating and lighting setups, and crops.  In this new version of Virtual Grower, we have transitioned from a downloadable PC application to a web interface.  Planned features and upgrades include the addition of LED lighting, ASHRAE heat balance calculations for more accurate heating and cooling loads, and multiple thermal zones to better model thermal curtains.

 

TX

 

PhD student Seonghwan Kang and Shuyang Zhen investigated the effect of orange light (peak at 627 nm) on growth, morphology, and photosynthesis of two lettuce cultivars and a dwarf tomato. When compared to a standard red light (peak at 660 nm), the use of orange light did not significantly improve (nor reduce) crop photosynthesis or growth. This contradicts previous findings that suggested orange light may support more efficient photosynthesis. The application of far-red light, in combination with orange or red light, significantly improve growth of both lettuce and dwarf tomato and promoted early flowering in tomato.

 

M.S. student Yilin Zhu and Shuyang Zhen evaluated how the intensity and duration of blue light at the end-of-production regulate anthocyanins production in red leaf lettuce. We found that blue light intensity and application duration co-regulate anthocyanin production, and sufficient anthocyanin production could only be achieved when both the threshold of blue light intensity and a minimal application duration are met.

 

At Dallas Center, Niu team compared the growth and mineral nutrition of two leafy greens, ‘Cegolaine’ lettuce and ‘Petite Star’ pak choy, under three commercial LED lights with different spectra and two temperatures: 21 ℃ and 30 ℃. In each temperature, there are three spectra: red and blue LED, and white LED with or without 5% far red (FR) of the total photon flux density of 250 mmol m^-2 s^-1. Results indicate that light spectra in this study had no or minor effect, while the two temperatures made significant differences in plant growth, morphology, yield and mineral nutrition in both species.

 

(Dallas) For microgreen indoor production, replacing or adding UV-A and far-red (FR) light to white LED affected growth, morphology, and phytochemicals. However, the magnitude of the effect is relatively small, possibly due to the relatively short period (from emergence to harvest of microgreens). Also, adding FR may reduce yield and some phytochemical concentrations of microgreens, similar to the results in baby leaves. Therefore, considering the costs of adding UV-A and FR to LED fixture, commonly available white LED lights are recommended for commercial production.

 

(Dallas) In another study, we determined the effect of temperature variation and blue and red LEDs on the elongation of arugula and mustard microgreens. Two microgreen species were grown under two light spectra and two temperatures, 18 ℃ and 28 ℃ under 110 µmol m⁻² s⁻¹ and a photoperiod of 12 h d⁻¹. The elongation promotion in arugula by blue light was greater at 18 °C than at 28 °C, showing interactions between light and temperature on most plant traits. For mustard, plant elongation was promoted at 28 °C compared to 18 °C independent of light treatment, showing no interactions between light and temperature on most plant traits. These results suggest that the blue light-mediated elongation as a shade-avoidance response is not reversed by high temperature, despite the varying sensitivity with temperatures and species.

 

(Dallas) Heat tolerance of eight spinach cultivars was determined based on plant growth index, biomass, and chlorophyll fluorescence measurement (potential maximum quantum efficiency of photosystem II, F_v/F_m, and performance index, PI_abs). Plants were grown under three temperatures: 22, 26, and 32 ◦C. Among the eight cultivars, Lakeside, Lizard, Seaside and Red Tabby grew more uniformly and were better quality at harvest than Space, Mandolin, Kolibri, and Koiwa. Koiwa had the lowest germination percentage and bolted under 26 ◦C.

 

(Dallas) Supplemental lighting (SL) is necessary to enhance growth and quality in greenhouse hydroponic leafy green production in Texas. We found that short-term SL with different commercial LED lights: UV-A and blue combination, red and blue LED, and full spectrum white LED are equally effective to significantly enhance the quality of leafy greens in terms of leaf thickness and greenness, antioxidant capacity, and concentrations of phytonutrients such as anthocyanins, carotenoids, and total phenolics; however, shoot fresh biomass and total leaf area were generally not affected by the short-term SL.

Objective 2: To reduce fresh water use and evaluate alternative fertilizers and growing substrates for the production of greenhouse crops

Planned Outputs:

1. Develop practical production guidelines to increase the efficiency of organic fertilizers in production of container-grown ornamentals and hydroponically-grown vegetables

Nutrient and nitrate composition of greenhouse-grown leafy greens: A trial comparison between conventional and organic fertility treatments. Frontiers in Sustainable Food Systems, 6(811995), 1-15.

 

TX

 

Information on growing organic vegetable seedlings under controlled environment is limited. At Dallas Center, weconducted experiments to determine the effects of three organic fertilizers (Sustane 4-6-4, Nature Safe 7-7-7, and Dramatic 2-4-1) and the rates (4 nitrogen (N), matched among the fertilizer treatments) in comparison to a conventional fertilizer with matching rates on the performance of watermelon seedlings. Due to the nature of organic fertilizers, it was difficult to match all the macronutrients levels. For comparison and convenience, we only matched N rates among treatments. Results indicated that both fertilizer type and rate significantly affected seedling growth and morphology. We found that K and P nutrients, in addition to N, significantly impacted seedling growth, morphology and mineral nutrition, especially root growth and morphology. We concluded that a combination of two or more organic fertilizers may be necessary to meet the nutrient requirement to produce healthy and strong watermelon seedlings.

 

2. Develop practical management guidelines to improve production efficiency and increase yield and quality of vegetables grown in recirculating hydroponics and aquaponics systems

DE

 

The University of Delaware collaborated with an industry partner, Croda, Inc. and validated that a calcium-mobilizing chemical biostimulant, when applied to the nutrient solution, was effective at reducing tipburn of greenhouse hydroponic lettuce ‘Rex’ by 88% compared to the control (without the biostimulant) without affecting biomass in a tipburn-inducing environment, thereby improving lettuce quality and sellable yield for controlled-environment hydroponic growers.

 

UF

 

Ying Zhang and his MS student, Jean Pompeo, investigated the effect of adapting higher air temperature setpoints, heat-tolerant crops, and root zone cooling (RZC) for improving the resource use efficiency in controlled environment agriculture, in terms of biomass production, energy, and water use efficiencies. Three lettuce cultivars were studied, including Rex, Skyphos, and Muir. Experiments were conducted where three lettuce cultivars were grown under warm air temperature settings of 24 °C, 26 °C, 28 °C, and 30 °C with a root-zone temperature of 22 °C and ambient. The results suggest that plant genotype (cultivar) is an important contributing factor to lettuce quality regardless of the temperature setpoints. RZC lowered fresh/dry biomass production and light/energy use efficiencies but improved water use efficiencies at all temperature treatments. Air temperatures at 28 °C produced the greatest overall yield, with its control group resulting in the highest light and energy use efficiencies, while 30 °C reduced yields for all except Muir, and its treatment group resulted in the lowest overall yields.

ME

 

The University of Maine started trials to compare cultivars of carrot (Daucus carota var. sativus ‘Mokum’, ‘Purple Haze’, ‘Deep Purple’, ‘Atlas’), kale (Brassica oleracea ‘Winterbor’, ‘Black Magic’, ‘Red Russian’, and ‘Redbor’), and peas (Pisum sativum ‘Avalanche’, ‘Royal’, and ‘Oregon Giant’) for hydroponic and container production in controlled environments. This work will continue through the next year.

 

NY

 

Cornell: Aquaponic trials were conducted with additional leafy greens beyond lettuce (previously tested) including arugula, kale, and Pac choi. Three fertilization methods were tested: conventional hydroponic, recirculating aquaponics (fish tank and plant hydroponic ponds in continuous recirculation), and aerobically digested fish solids. We found that recirculating aquaponics performed almost as well as conventional hydroponic for the leafy greens tests. Aerobically digested fish solids were not suitable as the sole nutrient source and should be amended with other nutrients for optimal yields.

TN

 

This study aims to determine which mizuna cultivar provides the best genotype for further light optimization studies. Twenty-two cultivars of mustard greens including 12 cultivars of mizuna were grown under ISS like conditions to determine which would provide the greatest yield and highest nutrient concentrations. Plants were grown for 31 days, harvested, and flash frozen. Morphological and fresh mass data were collected prior to freezing. Half of the plants were processed and analyzed to determine concentrations of carotenoids, anthocyanins, and vitamins C, B₁, and K₁. The remaining half were analyzed to determine concentrations of calcium, potassium, iron, and magnesium. This was conducted thrice and the resulting data was then normalized and weighted to determine which cultivar would provide the best phytonutrient and morphological profile for further optimization of space-based cultivation. It was found that ‘Green Amara’ (B. carinata) provided the best overall nutrient profile, while ‘Hybrid Red’ mizuna provided a complimentary profile for a more complete dietary supplement.

 

The objective of this study is to determine the optimal combination of light intensity and photoperiod when growing mustard green Brassica carinata ‘Green Amara’ under elevated CO₂ concentrations. This was determined by growing ‘Green Amara’ under 200, 400, 600, and 800 μmol·m^-2·s^-1 in a factorial design with a 16- or 24-hour photoperiod for a total of 8 treatment combinations. Seedlings were irrigated with deionized water with 100 mg·L^-1 N from 12.0-1.7-13.3 complete fertilizer supplemented with MgSO₄. After 14 days, seedlings were transplanted into raft hydroponic systems under the same environmental conditions, but with a nutrient solution providing 200 mg·L^-1 N and pH adjusted to 5.8 as needed. The plants were all grown under hyper elevated CO₂ (2,800 μmol·mol^-1) and a 23°C target air temperature to emulate ISS conditions. This was repeated twice over time. The plants were then evaluated according to a series of key metrics identified by NASA as important for future mission success, including morphological characteristics (mass, volume, and water content), mineral nutrient accumulation (Mg²⁺, Ca²⁺, K⁺, Fe³⁺), and phytonutrient concentrations (thiamine, ascorbic acid, phylloquinone, β-carotene, lutein, zeaxanthin, and total anthocyanins). After normalization and weighing, we found a combination of 800 μmol·m^-2·s^-1 and a 16-hour photoperiod provided the best overall profile of ‘Green Amara’ greens. Interestingly, this combination of light and photoperiod did not outperform the other treatments across each metric. Rather, it had an exceedingly high yield skewing the weighted ranking. The 200 μmol·m^-2·s^-1 and 16-hour photoperiod treatment ranked second, providing the highest scores across zeaxanthin, β-carotene, lutein, and ascorbic acid. However, this was outweighed by its lower yield. Interestingly, the increased photoperiod was associated with lower carotenoid concentrations while increased intensity was associated with greater plant mass but not with greater volume.

 

‘Hybrid Red Mizuna’ (Brassica rapa var. nipposinica) and ‘Green Amara’ mustard greens (Brassica carinata) were sown and placed in a growth chamber under light intensities of 200, 400, 600, or 800 µmol·m^-2·s^-1 for a 16-h photoperiod. The target air temperature was 23°C and the CO₂ concentration was superelevated at 2,800 ppm. After 14 days, seedlings were transplanted into a common greenhouse environment and grown for 10 days in a raft hydroponic system. At transplant and harvest leaf number, plant height, growth index (GI), dry matter concentration (DMC), and fresh and dry mass were quantified. At transplant, similar trends were seen in fresh mass, although the response of ‘Hybrid Red Mizuna’ was quadratic, and in leaf number, although this response was only seen in 'Green Amara'. Interestingly the DMC of 'Green Amara’ increased linearly with increasing light at transplant, a trend that was reversed at the time of harvest. Trends in plant height and in GI (calculated in part from plant height) were more complex, with discrepancies seen between replications and cultivars in response models (linear or quadratic) and in trends (increasing or decreasing with increased light intensity).

 

Increased sowing density could improve yields in controlled environment agriculture at relatively low cost. Culinary herbs are often grown for fresh use, and herb biomass yield and morphology characteristics dictate production profit. If we determine sowing density impacts on herb biomass yield and morphology, producers could benefit. Our primary objective was to determine the extent sowing density influences yield and morphology of four culinary herbs. Cilantro ‘Santo’ (Coriandrum sativum), parsley ‘Giant of Italy’ (Petroselinum crispum), mint (Mentha spicata), and sage (Salvia officinalis) seeds were sown in phenolic-foam substrate with 1, 5, 10, 15, or 20 seeds per cell. Seedlings were grown using ebb-and-flow hydroponic systems in a greenhouse with 23°C target average daily temperature. We maintained a 16-hour photoperiod with a target daily light integral of 14 mol·m^‒2·d^‒1. After 14 (cilantro), 21 (parsley, sage), or 28 (mint) days, seedlings were transplanted into hydroponic rafts for final production. Plants were harvested after 16 (cilantro), 21 (mint), 25 (sage), or 28 (parsley) days. During harvests we recorded height, number of surviving plants, stem and leaf fresh and dry mass, and leaf number. As sowing density increased, fresh mass per cell increased. However, in general, as sowing density increased, an increasing proportion of biomass was allocated to stems compared to leaves, thus reducing crop quality

 

3. Develop recommendations for application of flexible wavelength lighting and selective cover materials or shading elements for greenhouses

 

AZ (University of Arizona)

 

Kacira Lab, through collaboration and support of Red Sea company, evaluated the effect of wavelength selective (NIR blocking) greenhouse covering material on yield and quality of eight varieties of Roma tomato crop as well as several leafy greens including two varieties of lettuce, dill, and kale.

 

Wavelength altering properties of quantum dots in plastic film for the improvement of tomato and lettuce plant production was completed within a single-bay, gutter-connected, ETFE film-covered greenhouse 7.5 x 15.1 m, by Michael Blum and Morgan Mattingly, graduate students of Gene Giacomelli, in collaboration and support of Matt Bergren, UbiQD company.

 

4. Develop strategies to reduce water use in propagation of ornamentals and vegetables

 

IN

 

Gómez conducted experiments evaluating the effect of light quality and carbon dioxide concentration on water loss of unrooted cuttings propagated in indoor facilities

 

NJ

 

We completed the development of Rutgers Water Recycling Investment Tool. We created this online tool to allow producers to estimate costs and benefits of a water recycling investment at their commercial nursery, using information that they enter about their nursery operation. This tool then gives them a “regulatory risk score” based on their drought and pollution risk. Next, using a partial budget approach, the program determines the net present value of the investment, the upfront capital cost, and the expected change in annual cash flow. The tool is available at: https://tessera.rutgers.edu/recycle-flowchart/ This work was summarized in a peer-reviewed publication (Gottlieb et al, 2022).

 

5. Accelerate propagation timing by reducing water use

 

6. Generate new knowledge about environmental management practices that enhance beneficial microbes in hydroponic solutions

 

MD

 

Experiments: Conducted experimentation on identifying optimal temperatures for root growth and yield. This data is a precursor to experiments related to identifying microbes that a) increase root heat tolerance and/or b) decrease susceptibility to Pythium root rot.

 

7. Develop management guidelines to use low-quality water for irrigating greenhouse crops

 

KS

 

In follow-up to a Spring 2022 experiment, an undergraduate research project at Kansas State University was conducted during Summer 2023 to evaluate wastewater from a commercial water purification system for hydroponic lettuce production compared to reverse osmosis or municipal water. There were no growth differences across treatments. In addition to essential nutrients, sodium, chromium, arsenic, lead, and cadmium were measured in water sources, nutrient reservoirs, and plant tissue. Nutrient budgets were created to assess ion accumulation based on water source.

 

NY

 

Cornell: We developed hydroponic production techniques for a novel salt-tolerant hydroponic plant: ice plant (Mesembryanthemum crystallinum). Ice plant is found adjacent to salt-water coasts and is considered a halophyte (salt tolerant plant). It is a fast-growing edible succulent plant with a savory flavor. We determined that ice plant grows optimally when it has sodium chloride added to the hydroponic nutrient solution at 0.05 to 0.10 Molar and it can survive concentrations of 0.2 Molar (which is one-third as salt as seawater). When propagated from seed we found good growth/yield with a 4 week seedling period (144 plants per square foot) and then transplanted and grown on for three weeks. Ice plant benefited from supplemental lighting in winter greenhouse production. We believe this crop shows promise as a novel hydroponic crop and one that can also be used to reduce Na and Cl from accumulating in recirculating hydroponic and aquaponic nutrient solutions enabling more sensitive leafy greens (ex. lettuce) to grow in higher salinity water source.

 

OH

 

We developed a new hydroponic nutrient solution formula that would allow using low pH (4.0-4.5) solution for growing most common leafy greens (arugula, basil, lettuce, kale, pakchoi, and spinach) 

 

UT

 

Salt tolerance of Punica granatum ‘Wonderful’ (pomegranate) and four penstemon species

 

Two studies were conducted to evaluate the salinity tolerance of four penstemon species [Penstemon barbatus ‘Blue’ (Rock Candy series beardtongue), Penstemon strictus ‘Rocky Mountain’ (Rocky Mountain beardtongue), Penstemon davidsonii (Davidson's penstemon) and Penstemon heterophyllus (foothill penstemon)] in a greenhouse at the Utah Agricultural Experiment Station. We examined how varying salinity levels, with electrical conductivity (EC) ranging from 1.0 to 10.0 dS·m^-1, affected the growth and physiology of the penstemon species. Additionally, a separate greenhouse study was performed to assess the salinity tolerance of Punica granatum ‘Wonderful’ (pomegranate). Plants were irrigated with a nutrient solution at an EC of 1.2 dS·m^-1 (control) or saline solutions at EC levels of 5.0 or 10.0 dS·m^-1 for a duration of 8 weeks.

 

The experiments were designed using a randomized complete block design with ten replications. The salinity levels in the root zone were monitored after each irrigation using the pour-through technique described by Cavins et al. (2008). Various parameters including plant growth, visual quality, relative chlorophyll contents (SPAD readings), and physiological parameters such as net photosynthetic rate, stomatal conductance, transpiration rate, and water use efficiency were collected. Environmental variables such as temperature and solar radiation within the greenhouse were recorded throughout the course of the experiment.

 

8. Develop production guidelines to adjust nutrient programs to non-peat-based substrates
