Abstract
Domestic melon production has declined over the past three years due to unfavorable environmental factors and suboptimal fertilization, particularly the insufficient supply of phosphorus (P) and potassium (K). This study aimed to determine the effect of monopotassium phosphate (MKP) fertilizer concentration and application time, both individually and in combination, on the growth and yield of Sakata Glamour variety melon under a drip irrigation system. The research was conducted from February to April 2025 at the Greenhouse of the Food Security and Agriculture Office of Surabaya City, using a factorial Completely Randomized Design (CRD) with two factors: MKP fertilizer concentration (5, 10, 15, and 20 g/L) and application time (35&42, 42&49, and 49&56 DAP), resulting in 12 treatment combinations with 3 replications. The results showed that the combination of 15 g/L MKP concentration and application time at 42 & 49 DAP (K3T2) produced the best fruit weight (2.76 kg) and flesh thickness (6.00 cm), while the combination of 10 g/L concentration and application time at 42 & 49 DAP (K2T2) produced the best sweetness level (15.33 °brix). The single treatments of 15 g/L MKP concentration and application time at 42 & 49 DAP also significantly affected fruit volume and diameter. Based on these findings, the combination of 15 g/L MKP concentration with application time at 42 & 49 DAP is recommended to enhance the growth and yield of Sakata Glamour variety melon under a drip irrigation system.
