“…For instance, the concentration of yellow flavonoids was 70% higher in organic fruits when compared to fruits from conventional growing system, but only at the harvesting stage, which is consistent with similar observations previously [57]. The concentration in anthocyanins was lower in the fruits from organic farming at all three stages of fruit development [56]. These discrepancies indicate that organic farming had the effect of modifying the levels of transcripts or the activities of enzymes controlling intermediary steps of the biosynthetic pathway of phenolic compounds.…”

“…The more stress plants suffer, the more polyphenols they produce,' these authors point out [55]. Tomato fruits from organic farming experienced stressing conditions that resulted in oxidative stress and the accumulation of higher concentrations of soluble solids as sugars and other compounds contributing to fruit nutritional quality such as vitamin C and phenolic compounds [56].…”

“…It may be possible that the reduction in BER incidence by OMF under salinity in the present study was caused by an enhanced antioxidant system. Tomato fruits from organic farming are higher in superoxide dismutase activity (Oliveira et al, 2013), and the significant increase in the ascorbic acid contents of mature fruit in the winter cropping of Exp. 1 with OMF could show a correlation with this.…”

Effect of Organo-mineral Fertilizer on Tomato Fruit Production and Incidence of Blossom-end Rot under Salinity

et al. 2017

Tomato plants were grown with a drip irrigation system to evaluate the effects of a novel organo-mineral fertilizer [2:10:1 (w/w/w) mixture of calcium sulphate, ground rice bran, and humic acid] (OMF), which can mitigate salinity stress, on plant growth, fruit yield, and the incidence of blossom-end rot (BER) under salinity stress. Salinity stress was applied by drip irrigation with 50 mM of NaCl. Plant growth with OMF was lower than that with chemical fertilizer (CF). Higher levels of K and P were obtained in the leaves from plants grown with OMF. OMF inhibited Na accumulation and proline increase in the leaves and was considered to alleviate salinity stress. Salinity treatment caused a decrease in fruit weight and an increase in ascorbic acid, sucrose, glucose, fructose, and glutamic acid. Tomato plants grown with OMF had smaller fruit than with CF without salinity, but the incidence of BER under salinity was reduced by OMF. The water soluble Ca content of the distal half of young tomato fruit was significantly decreased with salinity treatment. The incidence of BER under salinity was significantly lower in OMF than in CF, but there was no difference in the concentration of every form of Ca between CF-salinity and OMF-salinity treatments. The reduction in BER incidence with OMF treatment could not be explained by the differences in Ca concentration. The mechanism of the reduction in BER with OMF was not clear, so further studies are necessary.

“…Few data are available about the influence of the growing conditions (region, growing system) and the fertility management strategy on the quality attributes of organic greenhouse crops (Ceglie et al 2015). A survey by Oliveira et al (2013) suggests that tomatoes from organic farming systems grown under conditions of stress show higher concentrations of sugars and secondary metabolites such as vitamin C and phenolic compounds that contribute to the nutritional quality of organic production. This has been also confirmed for organic strawberries produced in greenhouse conditions (Ceglie et al 2014).…”

AcknowledgementThis brochure is based upon work from COST Action FA1105 BioGreenhouse, supported by COST (European Cooperation in Science and Technology). The authors acknowledge COST Action FA 1105 "Towards a sustainable and productive EU organic greenhouse horticulture" for funding the meetings held in the framework of the activities of WG2 "Soil fertility, suppressiveness and water management" during which the main soil fertility issues in organic protected conditions were discussed. They wish to thank many colleagues for their contribution to this brochure and Ms. José Frederiks (Wageningen UR Greenhouse Horticulture) for processing layout and printing and Roger Hitchings for the proofreading.Link to the Action: http://www.cost.eu/COST_Actions/fa/FA1105 and: http://www.biogreenhouse.org/ AbstractThe management of soil fertility in organic greenhouse systems differs quite widely across Europe. The challenge is to identify and implement strategies which comply with the organic principles set out in (EC) Reg. 834/2007 and (EC) Reg. 889/2008 as well as supporting environmentally, socially and economically sustainable cropping systems.In this paper, written by a group of scientists of different geographical origin and with different background, the state of the art of the sector and the main characteristics of the European organic greenhouse cropping systems are described. The main bottlenecks and constraints are discussed with a particular reference to the regulatory framework in force. The most relevant issues that may influence the enforcement and future development of the sector have been identified as specific knowledge gaps. For each of them, the appropriate research needs were elaborated in a multidisciplinary perspective as forthcoming challenges for the whole sector. Although not exhaustive, given the wide heterogeneity of the implemented systems, this paper is able, for the first time, to give a structured outlook on soil fertility management in protected organic conditions on a European scale.ISBN: 978-94-6257-536-3 DOI (Digital Object Identifier): http://dx.doi.org/10.18174/373583 Correct citation of this documentTittarelli, F., Båth B., Ceglie, F.G., Garcia, M.C., Möller, K., Reents, H.J., Védie, H., Voogt, W. 2016.
