The present work introduce synthesis low grade zeolite from fly ash and its application as urea slow release agent on Zea mays growth. The characterization of the synthesized zeolites were determined using X ray diffraction method and FT-IR spectroscopy. The zeolite that has been formed is added to urea fertilizer with a weight ratio of urea: zeolite as follows 1: 1, 1: 2, 1: 3. As much as 3 kg of soil is put in a polybag series and was added with 3 g urea slow release fertilizers. The polybags were planted with Zea mays plant 1 week in old at a depth of ± 5 cm. The plant growth parameters which include plant height plant, number and colour of leaves were observed every 7 days for 4 weeks Base on the diffraction pattern and IR spectra, the characteristics of the synthesized zeolite is matching with standard zeolite A. The use of urea slow release fertilizer on Zea mays plants showed better growth than using urea fertilizer without zeolite slow release ingredients. The treatment of soil with urea/zeolite 1:3 proven to produce the best Zea mays growth in interaction time 4 weeks.
