| Popis: | Soil-bound intensive greenhouse production has been scrutinized for its sustainability due to contamination of ground water by over-fertilization resulting in leaching of nutrients. As environmental guidelines are becoming more restrictive worldwide, and especially in Europe, many greenhouse growers have converted to more sustainable production systems including rockwool culture with recycled water and organic cropping systems in soil. The increase in popularity of organic production systems has amplified the debate whether organically grown produce is healthier than conventional produce. So far, little is known about the variations in fruit quality associated with production systems for greenhouse grown tomatoes. Thus, two organic (organic fertilization with and without straw amendment) and three conventional tomato cropping systems (regular and increased nutrient solution in rockwool and regular fertilization in soil) were compared in order to evaluate differences in nutrient availability and effects on fruit quality over a three-year period. Three modern medium-sized round tomato cultivars and one old cultivar were compared. There were no significant interactions between cropping systems and cultivars, so that main effects of systems and cultivars could be evaluated. Fruit yields in the organic systems were similar to those obtained in the conventional soil-bound system, but 15% lower than in the regular rockwool system, even though nitrogen concentrations in soil were not limiting in any of the production systems. Frequent organic amendments resulted in higher soil contents in the organic system without straw than in the other soil-bound systems, indicating that the organic systems were not yet stable in terms of nutrient availability after three years. A fruit quality index, based on the contents of compounds such as lycopene, ß-carotene and vitamin C, was similar in all cropping systems. The old cultivar had a significantly higher quality index, but a lower yield than the other cultivars. According to this study, high quality tomatoes can be obtained through proper adjustment of the quantity and the source of nitrogen fertilizers in organic and conventional cropping systems and the use of selected cultivars with a high nutrient use efficiency for organic systems. zijn vergeleken gedurende een periode van drie jaar. De beschikbaarheid van nutriënten en de effecten op de vruchtkwaliteit in twee biologische en drie gangbare teeltsystemen van tomaat zijn vergeleken gedurende een periode van drie jaar. Drie moderne middelgrote ronde cultivars en één oude cultivar zijn vergeleken. De opbrengst is de biologische systemen waren vergelijkbaar met die van de gangbare grondgebonden teelt, maar 15% lager dan die van teelt op steenwol, ondanks dat de stikstofconcentraties in de grond niet beperkend waren. Een vruchtkwaliteitindex, gebaseerd op op concentraties van stoffe zoals lycopeen, β-caroteen en vitamine C, was vergelijkbaar voor alle teeltsystemen. De oude cultivar had een hogere vruchtkwaliteitindex, maar een lagere opbrengst dan de andere cultivars. Volgens deze studie kan een hoge kwaliteit tomaten verkregen worden door de juiste hoeveelheid stikstofmeststoffen toe te passen in biologische en gangbare teelten en het gebruik van cultivars met een efficiënte stikstofbenutting voor biologische teelten. |
