Abstract
In addition to being used as a snack, pumpkin seeds are an industrial product. It also has the potential to be used in the food, pharmaceutical, and cosmetic industries. Seed yield and quality are traits of economic importance. This study aims to determine the effect of vermicompost and different plant activators on the yield and some parameters of the pumpkin's quality. For this purpose, three plant activators [(ISR-2000 (I), Symbion-Vam (S), and Green-Miracle (G)] together with vermicompost (V) have been used. The experiment was conducted in the field of the Cukurova University Pozantı Agricultural Research and Application Center, Turkey. A total of 8 applications were made. Conventional fertilizer (CF) application was determined as the control group. The results showed that the applications increased the snack pumpkin's fruit, seed yield, and quality. The highest fruit and seed yield was obtained from CF (37.2 t ha-1, 101.42 g-1m2) application, followed by V+I (27.1 t ha -1, 80.09 g-1m2) application. Additionally, CF applications resulted in the highest fruit width (14.82 cm), length (23.31 cm), seed width (10.21 mm), and length (20.66 mm) of internal weight (74.33 %) measurements. Regarding mineral element and phenolic content, higher results were obtained when vermicompost and plant activators were combined. According to the study results, different doses of vermicompost may be recommended as an alternative to conventional fertilizer application in future studies.
