“…Conversely, a decrease in the amount of peat commonly leads to an augmentation in stability. Laun et al [ 54 ] demonstrated that, up to a 50% v/v reduction of peat, stability was not affected. This may be attributed to the proportion of fine organic matter in the compost that contributes to the binding of the constituent parts.…”

Peat is the most common used substrate in horticultural seedling production. To reduce peat in horticultural potted plant cultivation systems in general is an obstacle, even within the highly specialized horticultural industry. Next to soil-less cultivation systems as e.g. hydroponics, the horticultural industry is eagerly looking for suitable peat substitutes. The demands on these compounds are high, basically mimicking the physical properties of peat. A 100% replacement of peat for press-pots used in seedling production has not yet been found, and only mixes of peat and substrates exist. Several suitable peat substitutes with different properties are known, that usually are used as a share of a mixed peat-substitute substrate. A constrained mixture design was used to test substrates containing 50% v/v and 25% v/v peat and four peat substitutes (two composts and two wood fibers) for vegetable seedling production. By limiting the maximum quantities of each material to be added, there was no negative effect on the growth of Chinese cabbage (Brassica rapa subsp. pekinensis). This means a reduction in of peat to 25% v/v is possible without a change in substrate quality. The mixture design allowed a quick decision to be made regarding the most suitable peat-reduced mixtures. The surface response approach enabled the experimental results to be easily transferred to horticultural practices, additionally. This flexible and efficient method also allows the predictions to be used to meet specific crop management needs.

“…However, because of the increasing concern about climate change and the conservation of natural resources and sustainable production, different methodologies have been developed and evaluated to identify and facilitate the choice of substrate or mixtures alternatives to peat. 49,[78][79][80] Recent reviews discuss the physical, chemical and microbiological characteristics of different growing media, organic amendments, compost and agro-industrial residues extensively as an alternative to peat use, with significant emphasis on the production of vegetable seedlings and transplants in organic nurseries. 43,81,82 To this end, the use of sustainable and low environmental impact growing media, with an emphasis on optimising resources (such as water and substrates) and reducing the use of inputs (such as chemicals and fertilisers), without negatively impacting the economic efficiency of the transplant production industry, is becoming increasingly crucial in line with the current circular economy approach.…”

BACKGROUNDPrevious research has established that using high‐quality planting material during the early phase of vegetable production significantly impacts success and efficiency, leading to improved crop performance, faster time to harvest and better profitability. In the present study, we conducted a global analysis of vegetable seedlings and transplants, providing a comprehensive overview of research trends in seedling and transplant production to enhance the nutritional quality of vegetables.RESULTSThe analysis involved reviewing and quantitatively analysing 762 articles and 5248 keywords from the Scopus database from 1971 to 2022. We used statistical, mathematical and clustering tools to analyse bibliometrics and visualise the most relevant research topics. A visualisation map was generated to identify the evolution of keywords used in the articles, resulting in five clusters for further analysis. Our study highlights the importance of the size of seed trays for the type of crop, the mechanical seeder used and the greenhouse facilities to produce desirable transplants. We identified grafting and light‐emitting diode (LED) lighting technology as rapidly expanding technologies in vegetable seedlings and transplant production used to promote plant qualitative profile.CONCLUSIONThere is a need for sustainable growing media to optimise resources and reduce input use. Thus, applying grafting, LED artificial lighting, biostimulants, biofortification and plant growth‐promoting microorganisms in seedling production can enhance efficiency and promote sustainable vegetable nutritional quality by accumulating biocompounds. Further research is needed to explore the working mechanisms and devise novel strategies to enhance the product quality of vegetables, commencing from the early stages of food production. © 2024 The Authors.
