Response of Melon (Cucumis melo L.) to the application of Bio-slurry fertilizer and Trichoderma harzianum

This study aims to determine the best combination of bio-slurry and Trichoderma harzianum on melon production. The research was conducted in Lassang Village, North Polombangkeng District, Takalar Regency, South Sulawesi from June to August 2020. The experiment was set using a randomized block design with the application of bio-slurry fertilizer as the first factor consisted of control, 25, 50, 75 and 100 mL/L bio-slurry. The second factor was Trichoderma harzianum dose consisted of 0,100, 200, and 300 g / L. The results show that the application of 75 mL/L bio-slurry and 200 g/L Trichoderma harzianum resulted in thickest fruit meat (26.47 mm). Melon treated with Bio-slurry of 100 mL/L and 200 g/L Trichoderma harzianum produced the highest number of seeds (285.2 seeds) and higher concentration of the microbes of 300 g/L resulted in the highest Brix content (6.0% Brix) and the highest organoleptic test (2.90). The singe effect of Bio-slurry treatment of 100 mL/L also produced the earliest flowering age (14.40 days), the highest number of fruits (4.10 pieces), the heaviest fruit weight (205.20 g), and the highest average of fruit diameter (24.22 mm).
