“…This is consistent with findings from other studies showing the effect of comparative HT production on crops, like cut flowers, where longer stems are preferred (Ortiz et al, 2012). For production of other vegetables, such as those in the mustard (Brassicaceae) and nightshade (Solanaceae) families, growers typically favor a more compact transplant (biomass/length) with a thicker stem to ensure establishment in the field (Latimer, 1998;Vu et al, 2014). Likewise, slip morphology is an important consideration for sweetpotato propagators, and Barkley et al (2017) identified parameters that can contribute to the quality of slips for commercial production, such as vine length and the presence of nodes, which will subsequently form roots.…”

“…Fresh and dry weights, which have been normalized by slip length (milligrams per centimeter), are indicators of plant compactness (Vu et al, 2014). Ten of the 16 comparisons showed higher compactness values from slips grown in the OF and five of these were statistically significant [P < 0.05 (Table 4)].…”

“…In addition to measuring slip yield, the propagation bed trials in HT and OF systems sought to compare the individual slip quality of plants grown in the HT with those in OF system. Slip quality has not been defined in the literature for sweetpotato like it has for other crops (Latimer, 1998;Meyer et al, 2017;Vu et al, 2014), but Barkley et al (2017) identified slip length and the number of nodes as being important quality factors, especially for mechanical planting. Plant compactness has also been identified for transplanted crops such as tomato (Meyer et al, 2017) and is generally preferred for vegetable crops grown in the OF (Latimer, 1998).…”

Sweetpotatoes (Ipomoea batatas) are nutritious, easily stored, and well adapted to a variety of organic farming operations. This widely consumed root crop is propagated through the use of cuttings, known as slips. Slips are commercially grown primarily in the southeastern United States, and growers in the central United States still have limited access to sweetpotato planting material. Production of organic slips in high tunnels (HTs) could be a profitable enterprise for growers in the central United States given the season extension afforded by controlled-environment agriculture, which could allow growers to diversify their operations and facilitate crop rotation. In trials conducted in 2016 and 2017 at two research stations in northeast and south central Kansas, a systems comparison was used to evaluate the yield and performance of organic sweetpotato slips grown in HT as compared with the open field (OF), with four to six replications at each location. Propagation beds planted with ‘Beauregard’ seed roots in 2016 and ‘Orleans’ in 2017 were established in HT and OF under similar cultural methods and planting schedules. Slips were harvested from both treatment groups and transplanted to field plots to investigate the impact of production system on transplant establishment and storage root production. Slip yield from HT was greater than OF at both locations in 2016 (P ≤ 0.001), but this trend was inconsistent in 2017. Slips grown in HT were on average 12% less compact (slip dry weight per centimeter length) with fewer nodes than their OF counterparts in 2016. Nonetheless, mean comparisons for vine length, stem diameter, and total marketable storage root yield were not significant between HT and OF treatments (1.7 and 2.1 lb/plant, respectively). Similarly, the number of marketable storage roots for HT and OF groups was comparable (3.4 and 3.8 storage roots/plant, respectively). Although more research is needed to evaluate the feasibility of slips grown in HT and to determine recommendations for seed root planting densities, results from this study suggest that HT organic sweetpotato slip production could be a viable alternative to OF production as it relates to slip performance. According to this study, HT production could be a useful mechanism for growing sweetpotato slips, which could provide regional growers more control over planting material. Furthermore, HT slip production could promote the adoption of an underused vegetable crop that can be grown throughout many parts of the United States.

“…Plant compactness, which is the relationship of dry mass and plant height, is another important parameter to determined seedling quality. A transplant with high dry mass and short height is considered as a high quality seedling (Currey et al, 2012;Vu et al, 2014). If plant compactness is used as the main parameter to select light quality for the production of tomato seedlings, we recommend to increase the B PF (decrease stem length) to no greater than 50%B to maintain high growth rate (fresh mass, dry mass, leaf number) and maintain a short plant (compactness).…”

Lamp spectral customization can be a strategy to achieve desirable plant characteristics when plants are grown under sole-source electric lighting. Vegetable transplants can be efficiently and economically grown under indoor-production systems with electrical lighting; however, speciesspecific light recipes have to be developed to improve plant growth, development and morphology, as well as to reduce electrical consumption. The objective of this study was to evaluate the growth and morphology of tomato transplants to a broad range of blue to red (B:R) photon flux (PF) ratios under LEDs and cool white fluorescent lamps (CWF). Tomato "Komeett" and "Beaufort" seedlings were grown in a climate control growth chamber. Using LEDs, seven light treatments with different blue (B), green (G) and red (R) PF ratios were used: 100R, 10B:90R, 20B:28G:52R, 30B:70R, 50B:50R, 75B:25R and 100B. In addition, a CWF treatment served as the control. Hypocotyl length of "Komeett" decreased with the increase of percent B PF up to 75% B. Plant leaf area was 64-72% greater under treatments emitting both B and R PF than in the 100 B and 100 R treatments. Similarly, tomato "Komeett" fresh mass, dry mass, leaf

This review presents recent developments in plant photobiology and lighting systems for horticultural crops, as well as potential applications for cannabis ( Cannabis sativa and C. indica ) plant production. The legal and commercial production of the cannabis plant is a relatively new, rapidly growing, and highly profitable industry in Europe and North America. However, more knowledge transfer from plant studies and horticultural communities to commercial cannabis plant growers is needed. Plant photosynthesis and photomorphogenesis are influenced by light wavelength, intensity, and photoperiod via plant photoreceptors that sense light and control plant growth. Further, light properties play a critical role in plant vegetative growth and reproductive (flowering) developmental stages, as well as in biomass, secondary metabolite synthesis, and accumulation. Advantages and disadvantages of widespread greenhouse lighting systems that use high pressure sodium lamps or light emitting diode (LED) lighting are known. Some artificial plant lighting practices will require improvements for cannabis production. By manipulating LED light spectra and stimulating specific plant photoreceptors, it may be possible to minimize operation costs while maximizing cannabis biomass and cannabinoid yield, including tetrahydrocannabinol (or Δ 9 -tetrahydrocannabinol) and cannabidiol for medicinal and recreational purposes. The basics of plant photobiology (photosynthesis and photomorphogenesis) and electrical lighting systems are discussed, with an emphasis on how the light spectrum and lighting strategies could influence cannabis production and secondary compound accumulation.
