Abstract

Lettuce cultivation on Inceptisol in the drylands of Timor Island is constrained by low nutrient availability, especially nitrogen. The application of vermicompost fertilizer combined with NPK Phonska fertilizer is expected to increase the availability of N and lettuce yields through proper dosage settings. This study aims to obtain a combination dose of vermicompost and NPK Phonska fertilizer that gives the best effect on the availability of N and lettuce yield on Inceptisol in drylands of Timor Island. The research was designed in a single factor experiment using a completely randomized design. The treatments tested were the doses of combined vermicompost and NPK phonska fertilizers, namely: control/no fertilizer application (P0); 20t.ha-1 vermicompost + 200kg.ha-1 NPK phonska (P1), 20t.ha-1 vermicompost + 400kg.ha-1 NPK phonska (P2); 30t. ha-1 landfill + 200kg.ha-1 NPK phonska (P3); 30t.ha-1 landfill + 400kg.ha-1 NPK phonska (P4); 40t.ha-1 landfill + 200kg.ha-1 NPK phonska (P5); and 40t.ha-1 landfill + 400kg.ha-1 NPK phonska (P6). Each treatment was made in 3 replications so that 21 experimental units were obtained. The results showed that: (1) all treatments of combined doses of vermicompost and NPK Phonska fertilizers gave values of soil N-total content and plant tissue N that were significantly different from the control treatment, but no significant differences were found between the doses of combined vermicompost and NPK Phonska fertilizers; (2) the treatment of 40t.ha-1 vermicompost + 400kg.ha-1 NPK Phonska produced the highest fresh weight per lettuce plant which was not significantly different from the treatment of 40t.ha-1 vermicompost + 200kg.ha-1 NPK Phonska but significantly different from all other treatments. There was no best combination dose treatment of vermicompost and NPK Phonska fertilizer in this study.

Abstract

Lobak merupakan jenis tanaman sayuran bernilai gizi tinggi yang bermanfaat bagi kesehatan tubuh dan memiliki manfaat ekonomis lain yakni bahan baku industri tekstil dan kertas. Alfisol di lahan kering Pulau Timor berpeluang untuk dimanfaatkan sebagai lahan budidaya lobak namun perlu disertai dengan pengelolaan yang optimal berkaitan dengan tingkat ketersediaan hara yang rendah terutama fosfor. Penggunaan limbah cair tahu dapat menjadi alternatif peningkatan hara P dan hasil lobak karena mengandung unsur hara yang relatif tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan konsentrasi limbah cair tahu terhadap ketersediaan hara P dan hasil lobak pada Alfisol di lahan kering Pulau Timor. Penelitian dirancang dalam percobaan berpola faktor tunggal menggunakan rancangan acak lengkap. Perlakuan yang diuji adalah konsentrasi limbah cair tahu yakni: tanpa aplikasi limbah cair tahu/kontrol (P0), konsentrasi limbah cair tahu 15% (P1), 30% (P2), 45% (P3), dan 60% (P4). Hasil penelitian menunjukkan; (1) aplikasi limbah cair tahu dengan konsentrasi sebesar 15,%, 30%, 45%, dan 60% mampu meningkatkan kandungan Ptotal tanah sebesar 16,35% - 122,82%, total jumlah daun per tanaman sebesar 14,75% - 32,79%, panjang umbi sebesar 7,64% - 23,90%, volume umbi sebesar 1,21% - 73,17%, dan bobot segar umbi per tanaman sebesar 0,62 – 76,47% dibanding perlakuan kontrol; dan (2) perlakuan konsentrasi limbah cair tahu 60% menghasilkan kandungan P-tersedia tanah tertinggi yang berbeda signifikan dibanding perlakuan lainnya, sedangkan untuk parameter hasil tanaman, bobot segar umbi tertinggi dicapai pada perlakuan konsentrasi limbah cair tahu 60% yang berbeda tidak signifikan dengan perlakuan konsentrasi 45% namun berbeda signifikan dengan perlakuan lainnya.

Abstract

This research was carried out from March to July 2023 in the Fatukoa-Maulafa sub-district of Kupang, with the aim of determining the response to growth and yield of cayenne pepper plants (Capsium frutescens L.) due to the influence of doses of cow dung manure and the application of plastic mulch. This research is a factorial research using a Randomized Group Design (RAK). The factors tested consisted of the plastic mulch factor (M) with 2 levels, namely without mulching (m0) and black plastic mulch (m1) and the dose of cow dung organic fertilizer factor (K) consisting of 4 levels, namely without giving a fertilizer dose. cow manure (k0), cow manure organic fertilizer dose 10 tons ha-1, cow manure organic fertilizer dose 20 tons ha-1, and cow manure organic fertilizer dose 30 tons ha-1, so there are 8 treatment combinations. Each treatment combination was repeated 3 times. The data obtained was analyzed using variance analysis, and if the results of variance analysis showed a real effect, a test was carried out using the advanced Duncan Multiple Range Test (DMRT) at 5% level. The results of this study indicate that the interaction of the dose of cow dung manure with plastic mulch has a significant effect on the average LAB, average LTR, and weight of cayenne pepper fruit per plant, but the interaction has no significant effect on plant height, number of productive branches, and number of chili fruit per plant.
