“…Peningkatan tinggi tanaman diduga berkaitan dengan nilai kadar N daun yang relatif lebih tinggi dari kedua jenis pupuk dibandingkan perlakuan lainnya (Tabel 3). Pertumbuhan vegetatif tanaman khususnya pertumbuhan batang yang mampu memacu pertumbuhan tinggi tanaman terung dipengaruhi oleh ketersediaan unsur hara dalam tanah terutama nitrogen (Firmansyah et al, 2017).…”

Okra fruit contains phenolic compounds as natural antioxidant. The aim of this research was to analyze the effect of different types of fertilizers on production and quality of two okra varieties. The experiment was conducted in October 2017 to February 2018 at Bogor Agricultural University experimental field at Leuwikopo, Darmaga, Bogor (-6033’49.3”SL, 106043’30.7’’EL). The experiment used nested randomized complete block design with 2 factors and 4 replications. The first factor consisted of two okra varieties with different colour (red and green okra). The second factor was fertilizer types consisted of no fertilizer, organic (cow manure), combination of organic + inorganic, and inorganic fertilizer. The results showed that fertilizer types significantly affected plant height and fruit N content but did not affect fruit production. Red okra had a higher plant height, lower number of leaves and leaf K content than those of the green okra. The interaction effect of both factors was significant on total phenolic content in fruit and P content in leaf. The highest total phenolic content in fruit was showed by red okra with inorganic fertilizer, although it was not significantly different to those of red okra with combination organic + inorganic fertilizer, and also to green okra with organic fertilizer. The highest P content in leaf was found in red okra without fertilizer, however it was not significantly different to red okra with combination organic + inorganic fertilizer, green okra with organic fertilizer, and green okra with inorganic fertilizer.Keywords: inorganic fertilizer, leaf nutrient, organic fertilizer, phenolic compound

“…Lumpur sawit memiliki kandungan unsur hara N (27,03 kg/ton BK), P (2,54 kg/ton BK), K (15,5 kg/ton BK), Ca (14,20 kg/ton BK) dan Mg (7,36 kg/ton BK) (Wahyono et al, 2008) dari sumbangan unsur-unsur hara tersebut diduga dapat memenuhi kebutuhan unsur hara dalam meningkatkan komponen hasil kacang tanah. Firmansyah et al (2017) menyatakan bahwa selain berpengaruh pada komponen pertumbuhan, unsur hara N, P, dan K juga berpengaruh terhadap komponen hasil kacang tanah terutama pembentukan polong. Pada komponen hasil unsur hara N, P, dan K memiliki peranan masing masing dalam pembentukan polong.…”

[THE IMPACT OF PALM OIL SLUDGE RESIDUES AND DOLOMITE RESIDUES ON GROWTH AND YIELD OF PEANUT (Arachis hypogaea L.) IN ULTISOL]. This study aims to determine the best interaction between palm oil sludge (POS) residues and dolomite residues, determine the best POS residue, and determine the best dolomite residue in the growth and yield of peanut plants. This research was conducted from March 2018 to June 2018, the design used was a Complete Randomized Block Design (RCBD) with two factors. The first factor is POS residue with 3 levels, 0, 10, and 20 tons/ha. The second factor is dolomite residue with 4 levels, namely 0, 2, 4, and 6 tons/ha. The results showed that the best treatment combination was obtained from oil POS residue of 10 tons/ha and dolomite residue of 2 tons/ha which produced the highest total root nodule weights of 0.2417 g. POS residue of 20 tons/ha gives the highest yield on the growth component, which is an average plant height of 16.72 cm. POS residue of 10 tons/ha gave the highest yield on the growth component, namely dry stover weight of an average of 9.57 g, as well as the yield component of 45.20 total pods, 32.84 pods, total pod weight 43.47 g, and the weight of pith pods weighing 36.60 g. The highest total dry pod weight was 2.71 tons/ha. Dolomite residue gave a higher yield on all growth variables and observed results, with the highest total dry pod weight being 2.68 tons/ha.

“…Menurut Hardjowigeno (2010), unsur P di dalam tanah yang berasal dari bahan organik, pupuk buatan, serta mineral dalam tanah, memiliki fungsi dalam pembelahan sel, pembentukan albumin, mempercepat pematangan memperkuat batang, serta membantu pembentukan bunga, buah dan biji. T0D0 T0D1 T0D2 T1D0 T1D1 T1D2 T2D0 T2D1 Firmansyah et al (2017), tomat memerlukan unsur hara terutama N, P, dan K karena digunakan untuk pertumbuhan vegetatif, yaitu perkembangan akar, batang, dan daun. Jumlah daun yang lebih banyak memungkinkan penyerapan hara yang lebih optimum.…”

Sari. Penelitian ini bertujuan untuk mengetahui pengaruh bahan organik gulma paitan dan pupuk NPK terhadap sifat kimia tanah (C organik, N, dan P total), serta pertumbuhan dan hasil tomat pada Ultisols. Penelitian dilaksanakan di screen house Fakultas Pertanian, Universitas Jenderal Soedirman, Purwokerto, pada bulan Juni sampai September 2018. Penelitian ini menggunakan rancangan perlakuan faktorial 3x3. Faktor pertama adalah bahan organik tumbuhan paitan, terdiri atas 3 taraf, yaitu 0, 125, dan 250 g/tanaman. Faktor kedua adalah dosis NPK, terdiri atas 3 taraf, yaitu 0; 3,61; dan 5,42 g/tanaman. Seluruh kombinasi perlakuan dialokasikan ke dalam unit percobaan dengan menggunakan Rancangan Acak Kelompok yang diulang 3 kali. Variabel yang diamati meliputi C organik, N total, P total, serta pertumbuhan dan hasil tomat. Data dianalisis dengan uji F, dilanjutkan dengan Duncan’s Multiple Range Test. Hasil penelitian menunjukkan bahwa bahan organik tumbuhan paitan dengan dosis 250 g/tanaman cenderung memperbaiki sifat kimia tanah, serta berpengaruh terhadap pertumbuhan dan hasil tomat seperti jumlah daun, luas daun, bobot segar buah per tanaman sebesar 43,29% dari kontrol, dan jumlah buah sebesar 54,26% dari kontrol. Pupuk NPK dengan dosis 5,42 g/tanaman cenderung berpengaruh terhadap sifat kimia tanah, serta berpengaruh nyata semua variabel pertumbuhan dan hasil kecuali bobot segar akar. Kombinasi bahan organik tumbuhan paitan dengan dosis 250 g/tanaman dan pupuk NPK dengan dosis 5,42 g/tanaman cenderung berpengaruh terhadap sifat kimia tanah dan berpengaruh nyata terhadap variabel luas daun.Kata Kunci: Tithonia diversifolia, pupul NPK, Tomat, Ultisols Abstract. This research aims to know effect of organic matters of Tithonia diversifolia weeds and NPK fertilizer to soil chemical properties (organic carbon, total N, and total P), growth, and yield of tomato in Ultisols soil. The research was conducted at Screen House of Faculty of Agriculture, Jenderal Soedirman University, Purwokerto regency, from June to September 2018. This research used 3x3 factorial treatment design. The first factor was the dosage of organic matters of Tithonia diversifolia, consisted of 3 levels: 0, 125, dan 250 g/plant. The second factor was the dosage of NPK fertilizer, consisted of 3 levels: 0, 3.61, and 5.42 g/plant. All of treatment combinations were allocated to the experimental unit that used Randomized Block Design and was replicated 3 times. The variables observed were organic C, total N, total P, growth, and yield of tomato. Observational data were analyzed by F test, then Duncan's Multiple Range Test. The results showed that dosage 250 g/plant of organic matter of Tithonia diversifolia improved soil chemical properties, and affected significantly to growth, and yield variable likes number of leaves, wide of leaves, number of fruit, and fruit fresh weight. Dosage 5.42 g/plant of NPK fertilizer improved soil chemical properties, and affected significantly to all variables of growth, and yield, except root fresh weight. Combination of Tithonia diversifolia organic matter dosage 250 g/plant and 5,42 g/plant NPK fertilizer improved soil chemical properties and affected significantly to leaves area.Keywords: Tithonia diversifolia, NPK fertilizer, Tomato, Ultisols
