“…In Tunisia, although information on conventional tomato cultivation is widely available,5 little is known about organic cultivation practices. In an earlier study we evaluated a range of tomato cultivars and concluded that many of them were adaptable to organic production 6. However, we obtained lower yields than those usually recorded under conventional farming and therefore suggested that further organic fertilisation studies were needed to improve organic tomato yield and quality.…”

BACKGROUND: The agricultural production system and cultivation practices are critical factors in determining yield and food nutritional quality. Controversy remains regarding whether or not organic foods have a nutritional advantage when compared with their conventionally produced counterparts. In this study the effect of conventional and organic production systems on yield, physicochemical and nutritional properties of four field tomato cultivars (Perfectpeel, Rio Grande, Hypeel 108 and Firenze) was determined. In the organic system, different fertiliser combination treatments were used.

“…It was selected by the seventh generation, where the lines are assumed to be homozygous, stable, and suitable for field evaluation. The experiments have been implemented since the beginning of research work on the evaluation of the performance of open field organically grown tomato varieties in 2007 [17], and we report in this manuscript only the data from two years of investigations. The open pollinated 'Rio Grande', previously introduced by Petoseed (Saticoy, CA, USA) and actually, the only one distributed as organic seeds by the interprofessional grouping for vegetables (GIL) was employed as a control.…”

Agronomic Performance and Nutraceutical Quality of a Tomato Germplasm Line Selected under Organic Production System

Organic tomato production is increasing worldwide, thus making necessary the development of varieties adapted to this farming system. It is now well known that the implementation of local tomato plant breeding programs for organic farming is required to increase the performance of varieties in this typology of cultivation regime. In this research, the agronomic performance, nutraceutical contents, and radical scavenging activity of a tomato germplasm line (OSTGL), selected under organically grown conditions, were evaluated for two consecutive years (2018 and 2019) in comparison with the variety ‘Rio Grande’, frequently grown organically in Tunisia. Carotenoids, phenolics, vitamin C, and radical scavenging capacity were assayed spectrophotometrically, while tocopherols were analyzed by HPLC. All data were not affected by year-to-year variability. The OSTGL line showed significantly higher marketable yield, total phenol, flavonoid, vitamin C, α-tocopherol and γ-tocopherol contents, along with radical scavenging activity. The OSTGL red-ripe berries also showed comparable values for average weight, soluble solids, pH, titratable acidity, firmness and coloration, as well as lycopene and β-carotene contents. This open pollinated tomato germplasm line demonstrated to be an effective sustainable variety for improving fruit yield, agronomic, and nutraceutical characteristics under an organic management system.
