“…Opposite to Atiyeh et al (2000) and Hashemimajd et al (2004) where tomato plant growth was significantly increased after the addition of small doses of vermicompost to the potting media (up to 30%), in this study best results on plant growth and morphology were observed with the highest doses assayed (50, 75 and 100%). Most likely, such large substitution doses were possible because of the adequate pH and salt content of the pig slurry vermicompost and the persistence of favourable physical conditions for plant growth in the potting media with the increasing doses of vermicompost.…”

“…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.…”

“…In spite that several studies have addressed the effect of different types of compost (García-Gómez et al, 2002;Grigatti et al, 2007;Herrera et al, 2008) and/or vermicompost (Edwards et al, 2004;Hashemimajd et al, 2004;Tognetti et al, 2005) as potting or soil amendments on plant growth and yield, there are no studies concerning the effects of these two substrates in plant morphology when they are incorporated as potting substrates.…”

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...

“…This is in accordance with the studies of Truong and Wang (2015) on tomato seedlings. Optimized dosage of vermicompost was 20% in French marigold seedlings (Bachman and Metzger 2008), up to 60% of cattle manure vermicompost in Petunia (Arancon et al 2008), 40% of vermicompost in green house peppers ) and below 50% in tomato (Atiyeh et al 2000b;Hashemimajd et al 2006). Though some studies have also shown the best plant performance from 50 to 100% (Lazcano et al 2009).…”

Purpose To study the organic production in two varieties of Linum (Linseed) crop using different proportions of vermicomposts and combination of vermiwash as an environment friendly substitute to chemical fertilizers for organic farming of Linseed. Method Vermicompost prepared from cattle dung was mixed in different proportions, i.e. 0, 20, 40, 60, 80, and 100% vermicompost v/v with soil and commercial potting media (Perlite, Peat and Coconut coir). To study the germination, vegetative growth, reproductive growth and yield in two varieties of Linum usitassimum L. LC-54 and LC-2063 were grown in a polyhouse for a 2 years trial. A total of 960 seedlings and 240 plants were studied for assessment of result in 24 treatments. Additional treatments with foliar application of 1:1 v/v vermiwash and recommended dose of inorganic fertilizer were done to determine and compare the role of vermicompost, vermiwash and inorganic treatment. Results Substituting soil with 60% (v/v) vermicompost in LC-54 and with 40% (v/v) vermicompost in LC-2063 improved the performance of seeds, root morphology and stem growth. Life cycle of crop was shortened in two varieties of Linseed raised under different treatments of vermicompost and vermiwash. Performance of LC-54 was better at 60% and that of LC-2063 was at 40%, which can be attributed to their genotypic differences. Vermicompost proportion above 60% was of no use at any stage of life cycle in both the varieties of Linum. Germination and yield were further improved when foliar application of vermiwash was integrated with vermicompost for nutrient management when compared with recommended chemical fertilizer treatment and control. Conclusion Bio-efficacy of vermicompost and vermiwash for production of organic Linseed crop has been well established with enhanced yield.

“…It is also a sustainable solution for management of organic wastes which are major source of environmental pollution (Atiyeh, Subler, Edwards, Bachman, Metzger, & Shuster 2000b;Hashemimajd, Kalbasi, Golchin, & Shariatmadari, 2004;Lazcano et al, 2009). Recycling organic wastes could be done by thermophylic composting or mesophilic biodegradation.…”

Vermicompost may be a promising substitute for peat especially in transplant production. Vermicomposting is a sustainable solution for management of organic wastes. However, due to variability of organic wastes, vermicomposts might have varying nutrient content levels. The study compared vermicomposts from different sources on growth and nutrition of tomato (Solanum lycopersicum L.) transplants. Chemical composition of vermicomposts differed. Common characteristics were high pH and very high electrical conductivity. All vermicomposts stimulated growth of tomato transplants, with up to a 2.2-fold increase occurring in shoot biomass. Differences in growth were attributed mainly to differences in nutrient content of the potting mixtures, but some changes in physical and biological properties of the substrate could also be responsible.
