Soil properties analysis was carried out at the Laboratory of Chemistry, Biology and Soil Fertility of Soil Science Department, Faculty of Agriculture, Sriwijaya University. This experiment aims to study the effect of ecoenzym and SP-36 application on pH and P availability and growth of Mustard planted on Ultisol. This experiment was designed using the Completely Randomized Design consisting of 8 treatments which were B0: Control, B1: 10 ml L -1 ecoenzyme (EE), B2: 5 ton ha -1 of EE solid waste, B3: 50% recommended dose of 56.25 kg SP-36 ha -1 , B4: 100% recommended dose of 112.5 kg SP-36 ha -1 , B5: 10 ml L -1 EE + 5 ton ha -1 EE solid waste, B6: 50% recommended dose of 56.25 kg SP-36 ha -1 + 10 ml L -1 EE + 5 ton ha -1 EE solid waste, B7: 100% recommended dose of 112.5 kg SP-36 ha -1 + 10 ml L -1 EE + 5 ton ha -1 of EE solid waste. The treatment was replicated 3 times thus the total of experiment were 24 units. Variables observed were soil pH and P availability, growth and yield of Mustard. The results showed that the treatments of ecoenzyme and ecoenzyme solid waste and SP-36 fertilizer had significant effects on the soil pH, P-Availability, plant height, leaves number, root length, wet and dry weight of mustard. The B4 treatment with SP-36 treatment dose of 112.5 kg ha -1 resulted the best effect on soil pH and soil P-Availability, growth and yield of mustard.

Analisis tanah dilakukan di Laboratorium Kimia, Biologi dan Kesuburan Tanah, Jurusan Tanah, Fakultas Pertanian, Universitas Sriwijaya. Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh pemberian ecoenzym dan SP-36 terhadap pH tanah dan ketersediaan P serta pertumbuhan tanaman Sawi yang ditumbuhkan di Ultisol. Penelitian ini dilaksanakan dengan menggunakan rancangan acak lengkap (RAL), terdiri dari 8 perlakuan, yaitu B0: kontrol, B1: 10 ml L - 1 ecoenzym, B2: 5 ton ha -1 limbah padat ecoenzym, B3: 50% dosis rekomendasi 56.25 kg SP-36 ha -1 , B4: 100% dosis rekomendasi 112.5 kg SP-36 ha -1 , B5: 10 ml L -1 ecoenzym + 5 ton ha -1 limbah padat ecoenzym, B6: 50% dosis rekomendasi 56.25 kg SP-36/ha + 10 ml L -1 ecoenzym + 5 ton ha -1 limbah padat ecoenzym, B7: 100% dosis rekomendasi 112.5 kg SP-36 ha -1 + 10 ml L -1 ecoenzym + 5 ton ha -1 limbah padat ecoenzym. Setiap perlakukan diulang tiga kali, sehingga total percobaan sebanyak 24 unit. Peubah yang diamati adalah pH dan ketersediaan P tanah setelah sawi dipanen serta pertumbuhan dan hassil tanaman sawi. Hasil penelitian menunjukkan bahwa ecoenzym dan limbah padat ecoenzym serta SP-36 berpengaruh nyata terhadap pH tanah, P-tersedia, tinggi tanaman, jumlah daun, panjang akar, berat segar dan berat kering tajuk tanaman sawi. Perlakuan B4 dengan dosis 112.5 kg ha -1 SP-36 memberikan pengaruh terbaik terhadap pH dan P-tersedia, pertumbuhan dan hasil tanaman sawi. Kata kunci: Ecoenzym. Limbah padat ecoenzym, Ultisol, Sawi
