Replicated field trials at three matched farm pairs in southern and central Taiwan were established in October 2004 and 2005 to compare fruit quality and nutritional parameters of tomatoes grown on-farm under organic versus conventional management systems in tropical and subtropical environments. Two processing tomato varieties were evaluated using a randomized complete block design at each of the farms. Aggregation of farms by type (organic vs conventional) across two years resulted in no significant differences between organic and conventional farming systems for all tomato fruit parameters measured, including quality (pH, soluble solids, acidity, and color), content of bioactive compounds with antioxidant activity (beta-carotene, lycopene, ascorbic acid, and total phenolics), and antioxidant activity. This study indicated no consistent effect of the farming system on tomato fruit parameters. Farm management skills combined with site-specific effects contributed to high lycopene levels, and the choice of variety significantly influenced the content of bioactive compounds, particularly ascorbic acid and total phenolics.
2004年10月和2005年，在台湾南部和中部的三对匹配农场进行了重复田间试验，以比较热带和亚热带环境下有机种植与传统种植管理系统中农场种植的番茄的果实品质和营养参数。在每个农场使用随机完全区组设计对两个加工番茄品种进行了评估。两年间按类型（有机种植与传统种植）对农场进行汇总后发现，所测量的所有番茄果实参数，包括品质（pH值、可溶性固形物、酸度和颜色）、具有抗氧化活性的生物活性化合物含量（β-胡萝卜素、番茄红素、抗坏血酸和总酚类）以及抗氧化活性，在有机种植和传统种植系统之间均无显著差异。这项研究表明，种植系统对番茄果实参数没有一致的影响。农场管理技能与特定地点效应共同促成了高番茄红素水平，品种的选择对生物活性化合物的含量有显著影响，尤其是抗坏血酸和总酚类。
