This research aims to know the effectiveness of organic fertilizer from paitan leaf (P) and organic pesticide from mimba oil (M) based on the addition of microorganisms (photosynthetic bacteria and Streptomyces) to improve the function of paitan as organic fertilizer and mimba oil as an organic pesticide. The use of pesticides and organic fertilizers was tested on sweet corn (Zea mays var. Saccharata Sturt). The research was conducted in Mojolangu Village, Lowokwaru District, Malang City. The study was conducted from June to August 2016. The design using factorial Randomized Block Design (RBD) consisted of 2 treatments: Organic Fertilizer from Paitan (P) and Organic Pesticide from Mimba Oil (M). P0: No paitan fertilizer, P1: Dose of fertilizer paitan 10 ton ha-1, P2: Dosage of 15-ton ha 1 fertilizer. M0: Without Mimba, M1: Dosage of Mimba Oil 2.5g/plant, M2: Dosage of mimba oil 5g/plant, M3: Dosage of oil of mimba 7.5g/plant. The results showed that observation of crops resulted in interaction on the weight of sweet corncob with skin, the weight of sweet corn without skin, sweet corn length, and production per hectare. Provision of 15 ton/ha of fertilizer with 5g of mimba oil/plant and 15 ton/ha of paitan/ha with mimba oil 7.5g/plant gives the best yield per hectare. Fertilizer paitan directly affect plant height, leaf number, leaf area, plant dry weight, the diameter of cob, fresh weight of the plant, and sweet corn sugar. Fertilizer paitan 10 ton/ha and fertilizer paitan 15 ton/ha give better influence than fertilizer paitan 0 ton/ha.
