“…River valley soil is typically found in flood plains and has a lower silt content and a higher sand percentage. This soil contains goethite as the primary mineral (Arce and Rivera, 2018). Tepetzil has a discontinuous crystalline structure and high porosity due to the presence of clays (Vizcarra-de los Reyes, 2020).…”

Fruit tree cultivation requires rootstocks that are resistant to both biotic and abiotic stresses. The container size and substrate used are essential components in their development. Despite this, there are few studies on the impact of substrates on plant development in citrus trees under nursery conditions. This study aimed to assess the effects of three different ratios of pine bark in the substrate of three developing citrus rootstocks in a protected environment (greenhouse). The study conducted at the Cazones Nursery in Cazones de Herrera, Veracruz, Mexico, hypothesized that an increase in bark proportion would lead to a rise in the physical and chemical characteristics of the substrate and the development of the three rootstocks. The study utilized a completely randomized design with a factorial arrangement (A × B). Factor A (rootstock) had three levels: Citrus aurantium L. (Sour Orange), C. volkameriana Pasq. (Volkamer Lemon), and C. sinensis L. × Poncirus trifoliata L. (Citrage C-35). Factor B (substrate) had four levels (0, 10, 20, and 30 % pine bark), resulting in 12 treatments with 20 repetitions each. The physical and chemical characteristics of the substrates were determined, and the plant height and stem diameter were measured. Pine bark positively affected the apparent and real densities, total porosity, electrical conductivity, and cation exchange capacity. The growth dynamics of the three rootstocks were greater during the second and third months after grafting. When grown in substrates with a total porosity of 46–54 %, Volkamer Lemon, Citrage C-35, and Sour Orange rootstocks reached a plant height of 124.1, 110.5, and 84.5 cm, respectively; the stem diameter reached 6.9 mm. Porosity and cation exchange capacity increased when pine bark was added to the substrates. By evaluating the substrates and managing them proportionally, it is possible to obtain plants suitable for grafting (with 5 to 6 mm of stem) within four months after transplanting. This results in less time spent in the nursery and reduced costs.

“…The availability and cost of ingredients of the substrates also play an important role in deciding if the substrate is suitable for commercial production. Arce and Rivera [12] evaluated different substrate mixes and quantities of fertilizers on the growth of citrus rootstocks. The results showed that different rootstocks responded differently, but rice husk substrate was not suitable for citrus tree production at the nursery level.…”

Crop production in open fields is increasingly limited by weather extremes and water shortages, in addition to pests and soil-borne diseases. In order to increase crop yield, quality, and productivity, controlled environment agriculture (CEA) can play an important role as an alternative and supplemental production system to conventional open field production. CEA is any agricultural technology that enables growers to manipulate the growing environment for improved yield and quality. CEA production systems include high tunnels, greenhouses, and indoor vertical farming, as well as hydroponics and aquaponics. Currently, 'low-tech' CEA techniques such as high tunnels (plastic greenhouses with minimum or no cooling and heating) are primarily utilized in developing countries where labor costs are relatively low, and China has by far the largest area covered by high tunnels or 'Chinese-style' solar greenhouses. The most control-intensive 'high-tech' CEA approach, namely indoor vertical farming, has gained tremendous attention in the past decade by researchers and entrepreneurs around the world, owing to advancements in lighting technology, including use of light emitting diodes (LEDs), and increasing urbanization with new market opportunities. This special issue covers some of the CEA topics such as LED lighting, substrate, and hydroponics.

“…large or small) have obstacles during the production stage in a protected environment (MERLIN et al, 2012). Thus, selecting the appropriate substrate can be a difficult task that requires consideration of both physical and chemical features (ARCE; RIVERA, 2018). There are various substrate possibilities on the market, all of which are made from diverse material combinations; these substrates also have formulations and characteristics that are either known or unknown to the producers (FRANCO et al, 2007;ALMEIDA et al, 2018).…”

“…Aluminium, magnesium, and iron are all found in vermiculite, which is a hydrated silicate. Moreover, this mineral absorbs up to five times its volume in water; its presence in substrate composition boosts water retention capacity (REZENDE et al, 2010;ARCE;RIVERA, 2018). It also has a high capacity for cation exchange, making it a great candidate (REZENDE et al, 2010).…”

The length of citrus seedling development is determined by several factors, including the physical and chemical qualities of the substrate, which affect rootstock growth and, as a result, the quality of field seedlings. The purpose of this study was to see how the ‘Swingle’ citrumelo rootstock developed with different substrate formulations. The experiment was carried out in a seedling nursery from seeding to grafting, and six treatments were carried out, as follows: 60% peat moss, 30% fine grade horticultural vermiculite, 10% rice hulls (1); 60% peat moss, 30% fine grade horticultural vermiculite, 10% rice hulls (2); 50% peat moss, 30% fine grade horticultural vermiculite, 20% rice hulls (3); 50% peat moss, 30% fine grade horticultural vermiculite, 20% rice hulls (4); 50% peat moss, 20% fine grade horticultural vermiculite, 30% rice hulls (5); 50% peat moss, 20% fine grade horticultural vermiculite, 30% rice hulls (6). In addition, the experiment was divided into two stages: seeding (stage 1) and seedling nursery (stage 2). In a completely randomized design, the experiment has six treatments, four replications, and 51 plants per plot. When container transplanting was performed, the emergence percentage of seedlings was determined; thus, eight plants per plot were examined. For the second stage, was used a completely randomized design with 6 substrate formulations, 4 replications, and 20 seedlings per plot. Stem height, stem diameter, leaf number, area meter, root dry matter, leaf and stem dry matter, and quality index were measured on seedlings every 28 days. All substrate formulations improved seedling development until grafting, except for the 30% rice hulls, which hampered seedling development in ‘Swingle' citrumelo.
