Abstract

Tembakau merupakan salah satu tanaman yang diusahakan oleh petani di Jawa Barat.  Kondisi  tanaman tembakau tergantung dari nutrisi yang diberikan selama pertumbuhannya dan proses fisiologis yang menyertainya.  Nutrisi tanaman tembakau salah satunya berasal dari pupuk ZA.  Pupuk ZA terkadang sulit ditemui dipasaran, oleh karena itu penambahan bahan organik seperti biochar diharapkan dapat mengurangi kebutuhan akan pupuk ZA. Penggunaan biochar untuk mengurangi kebutuhan pupuk ZA akan mempengaruhi kondisi fisiologis saat tanaman tumbuh. Tujuan penelitian ini adalah untuk menganalisis bagaimana respons fisiologi dan biomassa tembakau terhadap aplikasi pupuk ZA dan biochar. Percobaan dilakukan pada bulan April 2024 sampai dengan Juli 2024 di Kebun Percobaan Ciparanje, Fakultas Pertanian, Unpad.   Percobaan ini menggunakan metode eksperimen yang disusun dalam Rancangan Acak Kelompok (RAK) dengan jumlah 6 perlakuan, 4 ulangan, masing-masing perlakuan terdiri dari 3 tanaman. Adapun perlakuan yang diaplikasikan adalah kombinasi beberapa dosis pupuk ZA dan biochar. Hasil penelitian menunjukkan bahwa perlakuan 12 g pupuk ZA/tanaman + 375 g Biochar Tempurung Kelapa/tanaman secara konsisten menghasilkan respons fisiologis (indeks klorofil, kadar N daun dan biomassa) tembakau terbaik. Terdapat tendensi  perlakuan 12 g pupuk ZA/tanaman + 563 g Biochar Tempurung Kelapa terhadap peningkatan serapan S daun tembakau.
UTILIZATION OF COW DUNG AND RABBIT URINE FERTILIZER TO OPTIMIZE THE GROWTH OF LIBERICA COFFEE SEEDLINGS (Coffea liberica L.) Rosniawaty, Santi; Abdul Halim luthfi; Intan Ratna Dewi Anjarsari; Mira Ariyanti; Rija Sudirja

Abstract

Liberica coffee (Coffea liberica L.) has the advantage of growing on marginal land and showing resistance to pests and diseases. To support optimal growth, Liberica coffee seedlings require appropriate growing media and nutrient sources. Cow manure and rabbit urine, as organic waste, are expected to provide sufficient nutrients. This study aimed to evaluate the effect of cow manure and rabbit urine on the growth of Liberica coffee seedlings. The experiment was conducted from February to June 2023 at the Ciparanje Experimental Garden, Faculty of Agriculture, Universitas Padjadjaran, using a randomized block design (RBD) with nine treatments and three replications. Treatments consisted of (A) soil + 2 g urea, (B) soil + 25% rabbit urine, (C) soil + 50% rabbit urine, (D) soil:cow manure (1:1) + 25% rabbit urine, (E) soil:cow manure (1:1) + 50% rabbit urine, (F) soil:cow manure (2:1) + 25% rabbit urine, (G) soil:cow manure (2:1) + 50% rabbit urine, (H) soil:cow manure (3:1) + 25% rabbit urine, and (I) soil:cow manure (3:1) + 50% rabbit urine. The application of cow manure and rabbit urine increased leaf area, root length, and chlorophyll index of Liberica coffee seedlings. The best growth was achieved with the combination of soil:cow manure (3:1) and 25% rabbit urine, which also increased the levels of total N, P2O5, and K2O in the seedlings.
