“…As a general consideration, it is possible to state that the main purpose of growing media is to satisfy the needs for good seedling growth within the limited space of a container and to prepare the seedlings for successful transplantation into the field. The quality of growing media is one of the main factors influencing the success of horticultural nursery activity (Raviv and Lieth 2008), and it is directly linked to the quality of the materials utilized in growing media formulations (Reis and Coelho 2007). The choice of appropriate substrate is therefore an important factor in promoting the optimum growth of plants.…”

A transplant can be defined as a seedling or sprouted vegetative propagation material grown in a substrate or in the field, for transfer to the final cropping site. Nurseries use a range of growing media in the production of transplants, and the quality of a substrate may be defined in terms of its feasibility for the intended use and also according to the climatic condition of the production site. Peat is the worldwide standard substrate, but because of its origin and the increasing environmental and ecological concerns, new alternatives have been proposed for organic production. Here, we reviewed these new alternatives, assuming that the proposed growing media will need to respond in a proper way to specific plant requirements while also taking them into consideration to be environmental friendly, at the same time. Appropriate composting management combined with suitable feedstock material can produce substrates with adequate properties to develop transplants. Potential added-value benefits of particularized compost have been highlighted, and these include suppressiveness or capacity for plant pathogen control, biofertilization, and biostimulation. This added value is an important point in relation to the framework of organic agriculture because the use of chemical fertilizers and pesticides is limited. Different permitted fertilizers are proposed by incorporating them by dress fertilization before planting or by foliar fertilization or fertigation during the seedling production phase. In this context, specific beneficial microorganism inoculation demonstrates better and quicker nutrient solubilization. Its inclusion during seedling production not only facilitates plant growth during the germination and seedling stages but also could bring efficient microorganisms or beneficial microorganisms to the field with the transplants. This review will help to bridge the gap between the producers of compost and the seedling plant producers by providing updated literature.

PAZDERŮ KATEŘINA, KOUDELA MARTIN: Infl uence of hydrogel on germination of lettuce and onion seed at diff erent moisture levels. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 6, pp. 1817-1822 The infl uence of Agrisorb (water solution 1, 3, 5 g/l) on lettuce and onion seed germination was tested in diff erent moisture conditions (30 ml and 15 ml of water in germination box). Variants with reduced water level germinated much more slowly (MGT parameter) than standard variants, though diff erences in total germination at the end of the test were insignifi cant. Treated variants of lettuce seeds showed a statistically signifi cant increase in germination energy (GE) on the fi rst day (GE1, both water levels), but a signifi cant decrease on the second day (columns GE2, 15 ml). Higher doses of Agrisorb slowed lettuce seed germination (GE2, 30 ml, dose 5 g) signifi cantly, similarly see GE2 (15 ml, doses 1, 3, 5 g). This slowdown was apparent for GE3 (both water amount) as well. A similar but insignifi cant eff ect was evident for onions. There was an infl uence of cultivar and seed vigour on sensitivity to water stress. The hydrogel application infl uenced germination of lettuce and onion seeds. Treated lettuce seeds germinated faster than non-treated control in the beginning of germination process. This eff ect was not recorded in case of slowly germinated onion seed lots. Although infl uence of Agrisorb was positive in the beginning, higher doses of hydrogel reduced germination energy of treated seed lots (for example GE2, GE4) of both crops in comparison with non-treated control. Higher doses of hydrogel caused longer MGT of lettuce and onion as well.

“…The type and quality of the growing media are considered one of the significant factors affecting the success of any horticultural production, and it is directly linked to the quality of the materials utilized in growing media [18][19]. Hence, the selection of a suitable substrate is an essential factor in promoting the optimal growth of crops; therefore, this study was conducted.…”

There is a growing interest among vegetable growers in using locally available growing media in hydroponic production. This study assessed the growth and yield of pechay, nutrient solution consumption of the plant, and its quality using different growing media (foam, coco peat, raw rice hull, raw saw dust, vermicompost, composted rice straw, composted rice hull) in a Kratky hydroponic system at the Institute of Agriculture, Camiguin Polytechnic State College-Catarman Campus, Tangaro, Catarman, Camiguin from June 10, 2021, until July 15, 2021. The study was laid in a Randomized Complete Block Design with seven treatments and three replications. Tukey’s Honest Significant Difference (HSD) was used to compare the significant differences between treatment means. Results showed that the type of growing media did not significantly affect the pechay growth performance, insect pests and disease incidence, nutrient solution consumption, and final quality of the hydroponic nutrient solution. However, a highly significant difference was observed in horticultural root development characteristics except for the percentage of root per plant and survival rate. In terms of yield parameters, highly significant differences were observed except for the number of marketable and non-marketable yields, the weight of non-marketable yields, and the harvest index. Our results showed that the use of foam could be used effectively to increase production under a hydroponic system. The use of organic growing media (raw rice hull, vermicompost, raw saw dust, coco peat) was also promising for their growth and yield performance. It can be concluded that the growing media affects the growth and yield of pechay in a hydroponic production system; however, the potential use of these various growing media should be further tested for verification.
