The use of nitrogen fertilizer accompanied by zeolite and fresh straw is expected to increase rice plant growth and the chemical properties of rice fields. The objectives of this research were to compare the effect of nitrogen fertilizer, zeolite, and fresh straw on the total - N , Cation Exchange Capacity (CEC) and the growth of paddy rice plants. This study used a factorial randomized block design method with 3 Factors: Nitrogen (Urea) : 0, 100, 200 and 300 kg/ha; Zeolite :0 and 300 kg/ha; and fresh straw treatment are without fresh straw and with the provision of 2 kg of fresh straw/plot equal to 5 ton/ha. Results showed that there was an increasement in the combination of urea, zeolite and fresh straw with low to high nutrient status but there were no significant differences. While there was a significant effect on plant height, number of tillers at 4 MST and dry weight of rice canopy. The combination of urea and zeolite fertilizers showed higher results than the treatment of urea fertilizer without zeolite. A combination of fertilizer urea and the zeolites show results higher than treatment fertilizer urea without zeolite.
