RESPON PEMBERIAN KNO₃ TERHADAP PERTUMBUHAN DAN KUALITAS HASIL BEBERAPA VARIETAS MELON (Cucumis melo L.) PADA SISTEM HIDROPONIK DRFT (DYNAMIC ROOT FLOATING TECHNIQUE)ALLYA DANIRABDALLAHauthorThis study evaluated the effects of KNO₃ dosage and melon varieties on growth and fruit quality. The experiment was conducted from September to December 2025 in Pandeglang Regency using a split plot design with four KNO₃ dosages (0, 2, 4, and 6 g/plant) and three melon varieties (Kinanti, Kirani, and Alisha), with three replications. Parameters observed included plant height, number of leaves, sugar content, fruit weight, and sensory sweetness. The results of this study indicate that the application of a 4 g/plant dose of KNO₃ had a significant effect on plant height at 6 weeks after transplanting (WAT) (237,44 cm), number of leaves at 5 WAT (35,11 leaves) and 6 WAT (35,56 leaves), and fruit weight (1,30 kg). Furthermore, in the variety treatment, it was found that the Kinanti melon variety (M1) had a significant effect on the plant height parameters at 2 WAT (52,92 cm), 3 WAT (81,08 cm), 4 WAT (177,17 cm), and 6 WAT (235,33 cm), number of leaves at 4 WAT (28,17 leaves), 5 WAT (34,17 leaves), and 6 WAT (34,75 leaves), and sensory sweetness level (4,58 score). The results of the study found an interaction between the application of 4 g/plant of KNO₃ and the Kinanti variety on the parameters of plant height at 5 WAT (214,67 cm) and sugar content (14,7 °brix), as well as an interaction between the application of 4 g/plant of KNO₃ and the Kirani variety on the parameter of fruit flesh thickness (3,70 cm).S Agriculture (General)2026-04-14UNIVERSITAS SULTAN AGENG TIRTAYASA;AGROEKOTEKNOLOGIThesis
