dc.description | ABSTRAK. Fosfor merupakan salah satu hara penting tanah dan aplikasi hara tersebut pada konsentrasi yang sesuai sangat berpengaruh terhadap pertumbuhan tomat. Penelitian tentang studi analisis fosfor tanah dan aplikasi pupuk fosfor pada budidaya tomat pada tanah Inceptisols dilakukan di Kebun Percobaan dan Rumah Kaca di Cikabayan, Institut Pertanian Bogor, dari bulan Maret sampai dengan November 2010. Tujuan penelitian ialah untuk mendapatkan metode ekstraksi fosfor tanah yang terbaik guna menentukan dosis pupuk fosfor pada budidaya tomat pada tanah Inceptisols. Penelitian menggunakan rancangan acak kelompok dengan perlakuan pemberian pupuk fosfor pada beberapa tingkat dosis yaitu 0X, ¼ X, ½ X, ¾ X, dan 1X, di mana nilai X ialah 368,5 kg/ha P2O5 dengan empat ulangan. Perlakuan pemupukan fosfor diterapkan pada 6 bulan sebelum penanaman tomat. Analisis korelasi dilakukan antara kandungan P tanah dan pertumbuhan tanaman yang ditanam di dalam rumah kaca menggunakan media inkubasi berasal dari tanah yang diberi perlakuan dan dianalisis. Uji fosfor tanah menggunakan lima metode ekstraksi, yaitu metode Bray I (NH4F 0,03 N + HCl 0,025 N, nisbah 1:7); Bray II (NH4F 0,03 N + HCl 0,10 N ); Mehlich I (HCl 0,05 N + H2SO4 0,025 N); Morgan Wolf (NaC2H2H3O2.3H2O; pH 4,8); dan Truogh [HCl 0,10 N + (NH4)2SO4; pH 3]. Hasil penelitian menunjukkan adanya perbedaan yang nyata antara pengaruh perlakuan pupuk P terhadap parameter tinggi tanaman, jumlah daun, dan diameter batang tomat. Bobot segar biomassa dan bobot kering tomat juga menunjukkan perbedaan pengaruh yang signifikan antarperlakuan. Nilai korelasi terbaik ditunjukkan oleh metode pengekstrak Mehlich I melalui parameter bobot kering dan bobot basah relatif tanaman. Dengan demikian, metode uji P tanah yang menggunakan Mehlich I dapat digunakan sebagai metode ekstraksi yang paling tepat untuk menganalisis unsur hara fosfor dengan koefisien korelasi 0,88, sehingga metode Mehlich I dapat diusulkan sebagai rekomendasi pemupukan P pada budidaya tomat pada tanah Inceptisols (nilai r = 0,89). ABSTRACT. Izhar, L, Susila, AD, Purwoko, BS, Sutandi, A, and Mangku, IW. 2012. Determination of the Best Method of Soil P Test for Tomato (Lycopersicon esculentum Mill. L) on Inceptisols Soil. Phosphorus is one of important soil elements and application of the element in suitable concentration give high effect on tomato growth. A study on phosphorus analysis and its application for recommendation of soil fertilization of tomato cultivation on Inceptisols soil was conducted at the field and Greenhouse of Cikabayan, Bogor Agricultural University, from March to November 2010. The objective of this research was to obtain the best extraction method of soil-P test for determining phosphorus nutrient required for tomato cultivation on Inceptisol soil. Rate of phosphorus of 0X, ¼ X, ½ X, ¾ X, and 1X, where X was 368.5 kg/ha P2O5 with four replications, was applied in the study. The treatments were applied 6 months before planting date. The research was arranged in randomized complete block design. Analysis of correlation between soil-P and plant growth based on data collected from the plants grown in the greenhouse using incubation media in treated-soil was analyzed. Soil-P test was carried out by using five extraction methods i.e. Bray I (HCl 0,025 N + NH4F 0.03), Bray II (NH4F 0.03 N + HCl 0.10 N), Mehlich I (HCl 0.05 N + H2SO4 0.025 N), Morgan Wolf (NaC2H2H3O2.3H2O; pH 4.8), and Truogh [HCl 0.10 N + (NH4)2SO4; pH 3]. The results showed that there were significant differences among the treatments of P fertilizer on the variables of plant height, leaf number, and stem diameter of tomato. Biomass fresh and dry weight of tomato also showed significantly different between the treatments applied. The highest correlation was shown on Mehlich I extraction reagent between plant dry and fresh weight. It means that, this P-nutrient extraction method was the most appropriate in determining phosphorus nutrient for tomatoes on Inceptisols soil with a coefficient correlation of 0.88. Mehlich I can also be used to develop a comprehensive phosphorus fertilizer recommendation for tomato cultivation on Inceptisols soil (r value = 0.89). | en-US |
