Abstract: Excessive inorganic fertilizers can exacerbate the impact of climate change on the agricultural sector, with an impact on decreasing soil fertility and crop production. The study aims to examine the role of the type and dosage of organic fertilizer on the morphology and physiology of red ginger. The study used a Completely Randomized Block Design with a Split Plot pattern with two factors: the type of organic fertilizer for the main plot, and the dosage as a subplot. The type of organic fertilizer consists of three levels: cow, goat, and chicken manure. The fertilizer dosage with three levels is 10; 20 and 30 tons ha-1. The fertilizer affects the morphology of red ginger, namely the number of shoots. Goat manure fertilizer with a dose of 30 tons ha-1 shows the highest number of shoots, namely 15.58 shoots. The type of fertilizer affects the physiology of red ginger, namely chlorophyll content and leaf area index. Goat manure fertilizer shows the highest chlorophyll content and leaf area index, namely 48.98 mg g-1 and 0.88 cm. Organic fertilizer can encourage plant growth and yield by reducing the impact of climate change.
