Indonesian paddy productivity has been declining in recent years, while the demand for paddy has increased along with the increase in the Indonesian population. One factor contributing to the decline in paddy productivity in Indonesia is the deterioration of soil quality in paddy fields caused by the continuous use of chemical fertilizers; consequently, one solution to improve soil quality is to apply soil amendments specifically humic acid and introduce beneficial microorganisms through the application of liquid bio-fertilizers. The aim of this research were to examine the effect of humic acid application, effect of biofertilizer application, and interaction of humic acid and biofertilizer application on the growth and yield of Mentik Wangi paddy. The method used was a Completely Randomized Block Design (CRBD) consisting of two factors. The first factor was the application of various doses of humic acid (0; 25; and 50 kg.ha-1) and the second factor was the application of various doses of liquid biofertilizer (0; 2,5; 5; and 7,5 L.ha-1). The observed variables included growth and yield components. The results showed that application of humic acid at a rate of 25 kg ha-1 can increase the panicle density index of Mentik Wangi paddy. Application of biofertilizer at a rate of 5 L.ha-1 (without humic acid) can increase the total number of tillers in Mentik Wangi paddy. The interaction between humic acid (25 kg.ha-1) and biofertilizer (5 L.ha-1) can increase the number of productive tillers and the productivity level of Mentik Wangi paddy.
