- This study aims to examine the effect of pelet fertilizer made of fly ash, azolla biomassa and TSP on available P and growth of Caisim (Brassica chinensis) on swamp soil. The study was conducted at the Greenhouse of the Faculty of Agriculture, Department of Soil Science and at the Laboratory of Chemistry, Biology, and Soil Fertility of the Faculty of Agriculture, Sriwijaya University. This activity began in December 2018 - February 2019. The method used in this study was a Complete Random Design (CRD) with 6 treatments, namely (P1) Control (without fertilizer), (P2), Pelet fertilizer, 0.5 dose times i.e. recommended 434 kg ha-1 Pelet fertilizer equivalent to 1.67 grams per 10 kg of soil, (P3) Pelet fertilizer, dose 0.75 recommended dose of 652 kg ha-1 pelet fertilizer is equivalent to 2.50 gram per 10 kg soil, (P4) Pelet fertilizer, dose 1.0 recommended dose of 869 kg ha-1 Pelet fertilizer is equivalent to 3.34 gram per 10 kg of soil, (P5) Pelet fertilizer, dose 1.5 recommended dose of 130 kg ha-1 pelet fertilizer is equivalent to 5.01 gram per 10 kg of soil, (P6) fertilizer P, dose 1 recommended dose of 434 kg ha-1 is equivalent to 1.66 grams per 10 kg of soil. The variable observed were initial soil analysis, plant height every week, number of leaves per week, soil pH every week, P available at harvest and wet weight and dry weight of caisim plants. The provision of Pelet fertilizer made from coal fly ash, azolla biomass and TSP increases the growth of caisim plants. the results showed that plant height was not significantly different while the number of leaves was not significantly different then the pH of the soil and the wet weight and weight of caisim plants were significantly different. Giving of Pelet made of coal fly ash, azolla biomass and TSP at recommended dose showed a significant effect on plant height, number of leaves as well as the wet weight and dry weight of the caisim plant
