| Judul Artikel | UJI AGRONOMI PUPUK N LEPAS LAMBAT PADA TANAMAN PAKCOY : PRODUKSI, SERAPAN N, DAN N-TERSEDIA INCEPTISOL |
|---|
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui pengaruh pupuk lepas lambat terhadap: 1) serapan N pada tanaman pakcoy, 2) jumlah kandungan N-Tersedia pada Inceptisol, dan 3) hasil produksi pada tanaman pakcoy. Pengujian peluruhan menggunakan lima formula pupuk nitrogen yang dikelat bahan lokal : F1 (60% Urea, 10% Azolla microphylla, 10% Montmorillonite, 10% Gondorukem, 10% Asam humat), F2 (70% Urea, 10% Azolla micophylla, 10% Montmorillonite, 10% Gondorukem) , F3 (70% Urea, 10% Azolla microphylla, 10% Montmorillonite, 10% Asam humat), F4 (70% Urea, 10% Azolla microphylla, 10% Gondorukem, 10% Asam humat), F5 (70% Urea, 20% Azolla microphylla, 10% Montmorillonite). Uji agronomis tanaman pakcoy menggunakan tanah inceptisol. Faktor uji agronomis yaitu lima formula pupuk ditambah perlakuan F0 sebagai kontrol. Kontrol digunakan untuk mengetahui keandalan lima formula tersebut; kontrol menggunakan urea, SP-36, dan KCl (Kontrol NPK). Penelitian uji agronomis tanaman pakcoy menggunakan Rancangan Acak Lengkap (RAL), dengan satu faktor berupa formula pupuk dan empat kali ulangan. Variabel yang diamati adalah pertumbuhan dan hasil tanaman pakcoy. Hasil penelitian menunjukkan bahwa formula pupuk nitrogen F4 yang lepas-lambatnya paling stabil dan secara bertahap. Formula pupuk nitrogen berpengaruh terhadap tinggi tanaman, bobot segar tanaman, bobot segar akar, bobot kering tanaman, jumlah daun, luas daun, serapan N, dan N tersedia.

| Abtrak (Bhs. Inggris) | The research aims to determine the influence of slow release fertilizers: 1) absorption of N in plants pakcoy, 2) amount of N content is available on Inseptisol, and 3) production at the plant pakcoy. The decay test uses five nitrogen fertilizer formulas which are chelated with local ingredients: F1 (60% Urea, 10% Azolla microphylla, 10% Montmorillonite, 10% Gondorukem, 10% humic acid), F2 (70% Urea, 10% Azolla micophylla, 10% Montmorillonite, 10% Gondorukem), F3 (70% Urea, 10% Azolla microphylla, 10% Montmorillonite, 10% humic acid), F4 (70% Urea, 10% Azolla microphylla, 10% Gondorukem, 10% humic acid), F5 (70% Urea, 20% Azolla microphylla, 10% Montmorillonite). The agronomic test of the pakcoy plant uses inceptisol soil. The agronomic test factor is five fertilizer formulas plus F0 treatment as a control. ). Controls are used to determine the reliability of those five formulas; Control using urea, SP-36, and KCl (NPK control). The agronomic analysis of the Pakcoy plant used a completely randomized design (CRD), with one factor in the form of a fertilizer formula and four replications. The variables observed were the growth and yield of pakcoy plants. The results showed that the F4 nitrogen fertilizer formula was the most stable and gradually released. Nitrogen fertilizer formula affects plant height, plant fresh weight, root fresh weight, plant dry weight, leaf number, leaf area, the absorption of N plants, and N available. |
