  • Title : The Effect Of Azolla Compost and Phosphate Rock Fertilizer Doses on Phosphor Availability and Yield of Peanut on Alfisols. The purpose of this experiment was to determine the best doses combination of azolla compost and phosphate rock which gives the highest availability P and peanut yield. The experiment was conducted from May to November 2012 at Dryland Research Center Faculty, at Jumantono subdistrict, Karanganyar and Soil Chemistry and Fertility Laboratory of Agriculture University of Sebelas Maret Surakarta. The experiment design used was completely randomized design (CRD) with the treatments combination of azolla compost and phosphate rock fertilizers i.e P0 (without treatment), P1 (75 kg ha-1 of phosphate rock), P2 (150 kg ha-1of phosphate rock), P3 (2,5 tons ha-1 azolla compost), P4 (2.5 tons ha-1 azolla compost and 75 kg ha-1of phosphate rock ), P5 (2.5 tons ha-1 azolla compost and 150 kg ha-1 phosphate rock), P6 (5 tons ha-1 of compost azolla), P7 (5 tons ha-1 of azolla compost and 75 kg ha-1 phosphate rock), and P8 (5 tons ha-1 azolla compost and 150 kg ha-1 of phosphate rock) and P9 (5 tons ha-1 manure) and P10 (50 kg ha-1 of urea, 100 kg ha-1 SP36, and 75 kg ha-1 KCl) as comparison treatments. The planting was conducted in the 30x40 cm pots filled with 12 kg of finely soil passes 2mm filter. Each pot planted with 3 seeds peanuts, then reduced to one crop per pot at 14 days after planting. Data were analyzed by F test 95% confidence level, if there is a significant influence followed by DMRT at 95% confidence level. Variables for this experiment are phosphor avaibility, CEC, organic matter, total N in the soil, fresh biomass and dry biomass peanut,height of the plant, fresh weight of pods, dry weight of pods, number of pods, dry seed weight and number of seed. The results showed that the best dose treatment was P8 which gives the highest of availability phosphor (13,01 ppm) and peanut yield (1,96 tons ha-1)
  • Tujuan penelitian ini adalah untuk mengetahui kombinasi terbaik pupuk kompos Azolla dan fosfat alam dalam meningkatkan ketersediaan P dan hasil kacang tanah. Penelitian dilaksanakan mulai bulan Mei 2012 hingga November 2012 di Pusat Penelitian Lahan Kering Fakultas Pertanian Universitas Sebelas Maret Surakarta, Kecamatan Jumantono, Kabupaten Karanganyar dan Laboratorium Kimia dan Kesuburan Tanah Universitas Sebelas Maret Surakarta. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan merupakan kombinasi dari kompos Azolla dan pupuk fosfat alam yaitu P0 (tanpa pupuk), P1 (75 kg/ha fosfat alam), P2 (150 kg/ha fosfat alam), P3 (2,5 ton/ha kompos azolla), P4 (2,5 ton/ha kompos azolla dan 75 kg/ha fosfat alam), P5 (2,5 ton/ha kompos azolla dan 150 kg/ha), P6 (5 ton/ha kompos azolla), P7 (5 ton/ha kompos azolla dan 75 kg/ha fosfat alam), dan P8 (5 ton/ha kompos azolla dan 150 kg/ha fosfat alam) sebagai pembanding adalah P9 (5 ton/ha pupuk kandang) dan P10 (50 kg/ha Urea, 100 kg/ha Sp36, dan 75 kg/ha KCl). Penanaman dilakukan pada pot dengan ukuran 30x40 cm yang diisi 12 kg tanah halus lolos 2mm filter. Setiap pot ditanami 3 benih kacang tanah, kemudian dikurangi menjadi 1 tanaman per pot pada 14 hari setelah tanam. Analisis data menggunakan sidik ragam pada aras kepercayaan 95%, apabila ada pengaruh nyata dilanjutkan dengan uji DMRT pada aras kepercayaan 95%. Hasil penelitian menunjukkan dosis rekomendasi terbaik adalah perlakuan P8 yang memberikan pengaruh paling baik terhadap ketersediaan fosfor tanah Alfisol (13,01 ppm) dan hasil kacang tanah paling tinggi (1,96 ton/ha).
