“…Plant mortality after compost introduction in the potting media has already been reported in previous studies and it has been attributed to the change in the physical properties of the substrate (i.e. increase in bulk density and decrease in pore and readily available water) (Papafotiou et al, 2005), to the increase in substrate salinity particularly in the case of tomato plants (García-Gómez et al, 2002;Castillo et al, 2004;Herrera et al, 2008) and to the presence of excessively high concentrations of certain ions (Hashemimajd et al, 2004). The compost used here was characterized by an excessively high pH and electrical conductivity as well as by high concentrations of Cl -as compared to the peat-based substrate and the vermicompost, and most likely, these three factors interacted synergistically to cause plant damage at the root level and subsequent plant mortality with 75 and 100% peat substitution.…”

“…Generally, replacement of peat with moderate amounts of compost or vermicompost produces beneficial effects on plant growth due to the increase on the bulk density of the growing media, and to the decrease on total porosity and amount of readily available water in the pots (Papafotiou et al, 2005;Bachman and Metzger, 2007;Grigatti et al, 2007). Such changes in the physical properties of the substrates might be responsible for the better plant growth with the lower doses of compost and vermicompost as compared to the peat-based substrate.…”

Post transplant success after nursery stage is strongly influenced by plant morphology. Cultural practices strongly shape plant morphology, and substrate choice is one of the most determining factors. Peat is the most often used amendment in commercial potting substrates, involving the exploitation of non-renewable resources and the degradation of highly valuable peatland ecosystems and therefore alternative substrates are required. Here the feasibility of replacing peat by compost or vermicompost for the production of tomato plants in nurseries was investigated through the study of the effect of increasing proportions of these substrates (0%, 10%, 20%, 50%, 75% and 100%) in target plant growth and morphological features, indicators of adequate post-transplant growth and yield. Compost and vermicompost showed to be adequate substrates for tomato plant growth. Total replacement of peat by vermicompost was possible while doses of compost higher than 50% caused plant mortality. Low doses of compost (10 and 20%) and high doses of vermicompost produced significant increases in aerial and root biomass of the tomato plants. In addition these treatments improved significantly plant morphology (higher number of leaves and leaf area, and increased root volume and branching). The use of compost and vermicompost constitute an attractive alternative to the use of peat in plant nurseries due to the environmental benefits involved but also due to the observed improvement in plant quality.Additional key words: peat moss, plant nursery, soil-less substrate, Solanum lycopersicum L. Resumen Compost y vermicompost como componentes de sustratos artificiales de cultivo en viveros: efectos en el crecimiento y morfología del tomateTanto las prácticas de cultivo en los viveros como la elección del tipo de sustrato tienen una gran influencia sobre la morfología de las plántulas y por lo tanto en su adaptación post transplante. Aunque la turba es uno de los sustratos más utilizados en viveros, su uso conlleva la explotación de un recurso no renovable y la degradación de las turberas, por lo que se hace necesaria la búsqueda de sustratos alternativos que puedan reemplazarla total o parcialmente. En este trabajo se investigó la posibilidad de reemplazar la turba por compost o vermicompost en la producción de plántulas de tomate, mediante el estudio de los efectos de proporciones crecientes de estos sustratos (0%, 10%, 20%, 50%, 75% y 100%) en parámetros morfológicos y de crecimiento claves para la adaptación post transplante. Compost y vermicompost mostraron ser sustratos adecuados para el crecimiento de las plántulas. La sustitución total de la turba sólo fue posible con vermicompost mientras que las dosis de compost mayores que el 50% produjeron la mortalidad de las plántulas. Las dosis bajas de compost (10 y 20%) y altas de vermicompost, produjeron incrementos significativos en la biomasa aérea y radicular de las plantas. Además estas dosis mejoraron de forma significativa su morfología (número de hojas, superficie foliar, volume...

“…Studies regarding soilless substrates have been performed on many important floricultural plants such as petunias (Arancon et al, 2008), begonias, tagetes (Grigatti et al, 2007), impatiens (Chavez et al, 2008), roses (Nazari et al, 2009), poinsettias (Papafotiou et al, 2004), gladioli (Ahmad et al, 2013) and antirrhinums (Mehmood et al, 2013). Growth substrates influenced the photosynthetic capacity, leaf area, and flowering potential, which play an important role in growth and development processes of plants.…”

“…Medina et al (2009) showed the possibility of using spent mushroom substrates in the production of horticultural seedlings replacing part of the peat in the growing media. Papafotiou et al (2005) reported the behavior of Syngonium podophyllum, Codiaeum variegatum and Ficus benjamina on media containing olive-mill waste compost, sphagnum peat, and perlite in different formulas and suggested that olive-mill waste compost can replace 25% of peat in a potting media for S. podophyllum and 75% of peat in C. variegatum and F. benjamina. Benito et al (2006) evaluated the use of pruning wastes compost for ornamental plants production of Lolium perenne L. and Cupressus sempervirens L. by preparing six growth substrates containing pruning wastes compost, peat, ground leaves, sand, and spent mushroom compost in different proportions and concluded that the pruning wastes compost could be used as a growing media component.…”

are two of the most widely spread plants on the market for annual potted ornamental plants. In order to identify the most adequate substrate formula we analyzed the effects of different potting growing media used for P. hybrida grandiflora 'Bravo' and N. alata 'Dinamo' on their photosynthetic capacity, leaf area, and flowering potential. Optimization of growing media formula for petunia and ornamental tobacco was performed by preparing four growing media mixing fallow soil (FS), Biolan peat (BP), acid peat (AP), leaf compost (C), and perlite (P) in different proportions. The physiological potential of petunia and ornamental tobacco was investigated by photosynthesis and respiration rate and chlorophyll pigments in leaves, while the vegetative and flowering phenological stages were evaluated by number of leaves per plant, leaf area, number of flowers per plant and leaf area/flowers ratio. These measurements were significantly influenced by the different potting growing media used in this study. In the flowering stage, the highest photosynthesis rates (8.612 µmol CO2 m -2 s -1 ) as well as leaf area (1.766 dm 2 ) of petunias were obtained on growing media with 60% biolan peat, 30% acid peat and 10% perlite (BP60-AP30-P10). Flowering responses to growing conditions vary greatly among plants and the biggest number of ornamental tobacco flowers (22 flowers plant -1 ) was registered as an effect of BP60-AP30-P10 media. Growing media with the BP60-AP30-P10 formula seem to be the most adequate growth substrate to develop profitable crops for petunias and ornamental tobacco with high decorative value.

“…Using root substrate blended with composted cotton burrs resulted in a lower dry weight and smaller bracts in poinsettias [11]. Composted organic materials amended with peat-based root substrate at different rates (50% poultry litter, yard trimmings or municipal solid waste composts; 25% polymer-dewatered bio solids or crab offal composts; 25% olive (Olea europaea) mill wastes compost; by volume) have been used for poinsettia production without a significant change in plant quality [12,13]. However, the disadvantages of those materials as alternative substrates are the lack of uniformity and risk of root substrate shrinkage during the plant production period [9,10].…”

A greenhouse study was conducted to evaluate the growth and development of poinsettia 'Prestige Red' (Euphorbia pulcherrima) grown in a commercial peat-based potting mix (Sunshine Mix #1) amended with biochar at 0%, 20%, 40%, 60%, 80%, or 100% (by volume) at four different fertigation regimes: F1: 100 to 200 mg·L −1 nitrogen (N), F2: 200 to 300 mg·L −1 N (control), F3: 300 to 400 mg·L −1 N, or F4: 400 to 500 mg·L −1 N. The experiment was a two-factor factorial design with 10 replications for each combination of biochar by fertigation. As the percentage of biochar increased, root substrate pore space and bulk density increased, while container capacity decreased. Root rot and red bract necrosis only occurred in F4 combined with 100% biochar. Plants grown in 40% biochar had a similar growth and development to those in 0% biochar. Up to 80% biochar, plants exhibited no significant change, except in terms of dry weight, which decreased at higher biochar percentages (60% and 80%). In summary, at a fertigation rate of 100 mg·L −1 N to 400 mg·L −1 N, up to 80% biochar could be used as an amendment to peat-based root substrate with acceptable growth reduction and no changes in quality.
