Kalmegh is a medicinal plant known for its properties in alleviating pneumonia caused by the coronavirus (COVID-19). This study aimed to investigate the application of organic fertilizer on the growth, yield, and yield quality of Kalmegh. The experimental design was a completely randomized design (CRD) with 3 replications and 5 treatments. Specifically, the treatments included treatment 1 as a control (no organic fertilizer) and treatments 2 to 5, in which organic fertilizer was applied at 0.5, 1.0, 1.5 and 2.0 times the dose recommended by the Department of Agricultural Extension. This corresponded to the application of organic fertilizer at 62.5, 125, 187.5 and 250 g/pot. The result showed that the application of organic fertilizer at 250 g/pot provided the highest leaf dry weight, which was not significantly different from the application of organic fertilizer at 125 and 187.5 g/pot. The increased dosage of organic fertilizer reduced the concentration of phosphorus in the plant tissue. However, the different doses of organic fertilizer had no effect on the andrographolide content. Regarding the chlorophyll content in the leaf, the application of organic fertilizer at 187.5 g/pot resulted in the highest chlorophyll a and total chlorophyll, which was not significantly different from the application of organic fertilizer at 125 and 250 g/pot. Consequently, the application of organic fertilizer at 125 g/pot is a suitable dose for the production of Kalmegh.
