The purpose of this rearch is to know the effect of the combination of biological agents with inorganic fertilizers and finding the correct dose for the combination of biological agents with inorganic fertilizer for the growth of sugarcane. The research was conducted in the village Pakiskembar, Pakis, subdistrict Malang. The study used a randomized block design with 7 treatments and 4 replications. Data were analyzed using Analysis of Variance (ANOVA); if there is a significant difference, then it is followed by a further test of LSD 5%. The results showed the effect of the combination of inorganic fertilizer with biological agents. There are significant differences in plant height and length of the rod at 139 DAP, stem diameter at 153 DAP, and the number of tillers at 97 DAP. P5 (NPK 300 kg ha−1 + ZA 400 kg ha−1 + Biofertilizer 30 L ha−1) is known to give good growth in most but not significantly different from P1 (NPK 400 kg ha−1 + ZA 600 kg ha−1). A combination of inorganic fertilizer with biological agents can lower the dose of inorganic fertilizer, and biological agents can provide nutrients needed for sugarcane so that the use of inorganic fertilizers can be reduced.
