In this study, the effects on seedling growth and quality of applying Prohexadione-Calcium (Pro-Ca) and different fertilizer dosages in Melis F1 tomato variety have been examined. In the study, 3 different fertilizer dosages, optimum dosage, 50% reduced and 50% increased dosage, and also 5 different (0, 30, 60, 90, 120 mg(-1)) Pro-Ca dosages have been applied to Melis F1 tomato variety. According to the study findings, it has been observed that the application of Pro-Ca dosages, other than with NPK fertilizers, has particularly slowed down extreme growth in measured parameters of tomato seedlings, and the use of NPK fertilizer applications with Pro Ca has reduced the impact of Pro-Ca. Even though Pro-Ca treatment prevents extreme growth of tomato plants, it did not have any significant impact on the dry matter weight of the plants. All Pro-Ca dosages have an effect on seedling growth, however the results acquired in dosages lower than 120 ppm have varied, therefore it has been decided to use the Pro-Ca in 120 ppm dosage.eninfo:eu-repo/semantics/closedAccessSeedling maturityVegetableSeedlingTomatoProhexadione-CalciumArticle282A13811386WOS:000461270800042Q4
