Abstract
ABSTRAK Penelitian ini bertujuan untuk mengetahui kombinasi dosis dan frekuensi pemberian pupuk urea yang paling optimal dalam meningkatkan produktivitas rumput pakchong. Penelitian ini dilaksanakan pada Febuari- April 2025 bertempat di Laboratorium Lapang Terpadu, Fakultas Pertanian, Universitas lampung. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola faktorial (3x3), dengan 3 ulangan sehingga tedapat 27 petak pecobaan. Perlakuan dalam penelitian ini adalah: faktor I (dosis pupuk urea) terdiri atas 100 kg N/ha, 150 kg N/ha dan 200 kg N/ha. Faktor II (frekuensi pemberian pupuk urea) terdiri atas Umur 16 hari (1x), 16 hari dan 32 hari (2x) dan 16 hari, 32 hari dan 48 hari (3x). Variabel yang diamati yaitu bobot segar, bobot kering dan jumlah anakan. Data yang diperoleh dianalisis menggunakan analisis ragam ANOVA (Analysis of Variance) dan uji lanjut BNT. Hasil dari penelitian ini menunjukkan bahwa perlakuan pemberian pupuk urea dengan dosis pupuk dan frekuensi tidak berpengaruh nyata (P>0,05) terhadap bobot segar, bobot kering dan jumlah anakan. Kata kunci : dosis pupuk urea, frekuensi pemberian pupuk urea, produktivitas rumput pakchong, pupuk urea, rumput pakchong. ABSTRACT This research aims to determine the optimal combination of urea fertilizer dosage and application frequency to increase the productivity of pakchong grass. The study was conducted from February to April 2025 at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. This research utilized a Completely Randomized Design (CRD) with a factorial pattern (3x3), with 3 replications resulting in 27 experimental plots. The treatments in this study are: factor I (urea fertilizer dosage) consists of 100 kg N/ha, 150 kg N/ha, and 200 kg N/ha. Factor II (frequency of urea fertilizer application) consists of 16 days (1x), 16 days and 32 days (2x), and 16 days, 32 days, and 48 days (3x). The observed variables include fresh weight, dry weight, and the number of tillers. The obtained data were analyzed using ANOVA (Analysis of Variance) and the BNT follow-up test. The results of this study indicate that the application of urea fertilizer with dosage and frequency did not have an effect (P>0.05) on fresh weight, dry weight, and the number of tillers. Keywords: urea fertilizer dosage, frequency of urea fertilizer application, productivity of pakchong grass, urea fertilizer, pakchong grass.
