“…Porosity improves the aeration and water-holding capacity of the medium (Melo et al, 2019). Water retention favours the imbibition process by absorbing water through colloids of the dry seed coat and hydrates protoplasm which further activates the synthesis of enzymes enhancing other biochemical processes responsible for seed germination and seedling emergence (Abdel-Razzak et al, 2019). However, the seedling emergence was reduced in the treatments with high levels of EC.…”

“…These properties make it to be the main substrate component for seedling production in containers (Aendekerk, 2000). Despite its tremendous advantage, it is an expensive material for farmers (Abdel-Razzak et al, 2019). Peat is non-renewable and environmentally unfriendly as it degrades very slowly and simultaneously emits the bound carbon as CO 2 which contributes to greenhouse gas (Raviv, 2013).…”

Tomato is an important horticultural crop as it provides income and contributes to food security for Rwandan citizens. Besides its importance, its production is hampered by the use of a soil-based growing medium which results in the production of low-quality transplants. This is mainly attributed to the unaffordability of peat moss to small-scale farmers in Rwanda. Hence, a greenhouse nursery experiment was carried out at the Rwanda-Israel Horticulture Centre of Excellence to search for an alternative growing medium to peat moss. Nine different growing media were formulated from a mixture at different ratios of sand, goat manure, and carbonised rice husks. The seeds were sown in propagation trays. The experiment was laid out in a randomised complete block design (RCBD) with four replications. Data obtained were subjected to analysis of variance and means were separated using Tukey’s honestly significant difference test at p ≤ 0.05. The data analysis was carried out using SAS software version 9.2. The results revealed that sand + goat manure + carbonised rice husk 50 %: 10 %: 40 % (T8) was comparable to T1 (peat moss 100 %) in producing higher quality seedlings during both trials with a mean quality index of 0.28 and 0.31, respectively, whereas T2 (sand 100 %) had seedlings with the poorest quality. Consequently, T8 can be adopted by nursery producers as an alternative to peat moss in the production of quality tomato transplants. More research on other locally available organic substrates is encouraged to find out alternatives to expensive media like peat moss because it was observed that the use of sand + goat manure + carbonised rice husk 50 %: 10 %: 40 % revealed in production of quality seedlings with no significant difference from the ones grown in peat moss.

“…The delay of seed germination in compost as compared to peat is in accordance with works of Herrera et al (2008) and Zaller (2007) for municipal solid wastes compost and vermi-compost, respectively. Faster stimulation of the germination's process in peat might stem from its promising total porosity (Table 1) that ensures better waterholding capacity (Abdel-Razzak et al, 2018) and aeration for seeds (Cai et al, 2010;Martin & Brathwaite, 2012).…”

This research was carried out in the experimental site of the Arid and Oasian cultures Laboratory of the Institute of Arid Regions, Medenine, Tunisia. It aims at studying the effects of compost on seed germination patterns, seedling growth, and plant development of muskmelon and tomato under greenhouse conditions. Three growth media were used: compost of date palm wastes and two reference media (peat and perlite). The results showed that compost presented a promising threshold of both maturity and stability, which is related to its neutral pH, C : N ratio, greater humic acid vs fulvic acid, and low values of chlorophyll-type compounds. Seeds of muskmelon and tomato germinated at varying liquid compost extract concentrations and muskmelon reached higher germination index values even at the pure extract solution (100%). Moreover, seeds of both species germinated relatively faster in peat than in compost and an overall delay in germination was observed, with a more pronounced reduction on tomato germination percentage. Produced seedlings have attained a similar vigour index among media (p <0.05). Compost of date palm was more suitable for muskmelon stem elongation and leaf-enlarging capacity than perlite. However, the gustative quality of fruits was not significantly affected by the medium-types. Thus, it is concluded the promoising effect of compost of date palm as potting medium and substrate in soilless culture under greenhouse conditions unless a pertinent choice of cultures.

“…Side-flows and waste from vegetable processing can also be recirculated back to the field in the form of compost and used as growth substrates. Tomato waste compost may be used to replace partially peat-based substrate used for vegetable transplants production in nurseries [97]. Tomato side streams may also be used as raw material for the production of organic fertilizer or soil amendment.…”

There is a large potential in Europe for valorization in the vegetable food supply chain. For example, there is occasionally overproduction of tomatoes for fresh consumption, and a fraction of the production is unsuited for fresh consumption sale (unacceptable color, shape, maturity, lesions, etc.). In countries where the facilities and infrastructure for tomato processing is lacking, these tomatoes are normally destroyed, used as landfilling or animal feed, and represent an economic loss for producers and negative environmental impact. Likewise, there is also a potential in the tomato processing industry to valorize side streams and reduce waste. The present paper provides an overview of tomato production in Europe and the strategies employed for processing and valorization of tomato side streams and waste fractions. Special emphasis is put on the four tomato-producing countries Norway, Belgium, Poland, and Turkey. These countries are very different regards for example their climatic preconditions for tomato production and volumes produced, and represent the extremes among European tomato producing countries. Postharvest treatments and applications for optimized harvest time and improved storage for premium raw material quality are discussed, as well as novel, sustainable processing technologies for minimum waste and side stream valorization. Preservation and enrichment of lycopene, the primary health promoting agent and sales argument, is reviewed in detail. The European volume of tomato postharvest wastage is estimated at >3 million metric tons per year. Together, the optimization of harvesting time and preprocessing storage conditions and sustainable food processing technologies, coupled with stabilization and valorization of processing by-products and side streams, can significantly contribute to the valorization of this underutilized biomass.
