<![CDATA[Research to determine of formulation humic substance and Trichoderma sp to increase the production and growth of corn (Zea mays, L). This research was conducted by extracting humic substance with fractionation organic matter method from cattle manure organic material. Trichoderma sp grow on corn medium and harvested after reaching a density of 1015 cfu. Created this compound formulation with mixing humic substance and Trichoderma sp. Indicator plant with F1 sweet corn Jago varieties. Application used humic substance in range 8%, 16%, and 32% on the recommended use NPK fertilizer for corn, as well as control without humic substance.
