Increased shallot yield with aplication of organic fertilizer. Cajeput waste as a source of organic fertilizer is very abundant in Ponorogo. Research aimed to study the aplication of organic fertilizers and Trichoderma asperellum to incerase growth and yield of shallot. The experiment was laid-out in factorial randomized completely design with 3 replications and eight treatment combinations. The first factors is organic fertilizer ( without organic fertilizer; 6 ton ha -1 of cajeput waste compost, 3 ton ha -1 of cajeput waste compost + 3 ton ha -1 of rabbit manure, 6 ton ha -1 of rabbit manure). The second factors is Trichoderma asperellum (without T. asperellum and 1 L ha -1 of T. asperellum ). The results of this study showed that treatmen of 3 ton ha -1 of cajeput waste compost + 3 ton ha -1 of rabbit manure without Trichoderma asperellum increased plant hight and leaf dry weight of shallot by 25% and 135,66%. The application of combination rabbit manure and without T. asperellum increased shallot tillering number by 9,67 tillering. The application of 3 ton ha -1 of cajeput waste compost + 3 ton ha -1 of rabbit manure increased shallot yield and diameter of shallot bulbs.
