Abstract

Melon cultivation is usually cultivated in the highlands, but the development of melon cultivation in the lowlands has the potential to be developed. The problem is that ultisol with low fertility dominates the soil in the lowlands. Cultivating melons in polybags makes it possible to provide ideal nutrients for plant needs. The right frequency of fertilization can provide appropriate nutrients for each phase of plant growth. The study aimed to determine the best dose and frequency of potassium fertilizer application and the interaction between the two on the growth and yield of melon plants and the sweet taste of melons. The study used a randomized block design (RBD). Factor I: Potassium dose (D) 4 levels: control: 0 g per plant, D1: 30, D2: 40, D3: 50. The second factor is the frequency of application of Potassium (F) consisting of 3 levels, namely: F1: 4 times, F2: 6, and F3: 8. The results of the study showed that the frequency of application of potassium fertilizer had a significant effect on the flowering age of melon plants. A potassium fertilizer dose of 50 g per plant (D3) gave the best fruit weight and diameter and a higher sweetness than other treatments. Keywords: Lowland, Fertilization frequency, Polybag cultivation, Potassium dosage.

Abstract

Penelitian ini bertujuan untuk mengetahui respon pertumbuhan dan produksi cabai merah (Capsicum annum L.) pada budidaya organik dengan menggunakan pupuk organik campuran pelepah dan tandan kosong kelapa sawit. Penelitian dilaksanakan pada bulan November 2022 sampai bulan April 2023, di Desa Lubuk Sini, Kecamatan Taba Penanjung, Kabupaten Bengkulu Tengah, Propinsi Bengkulu. Percobaan mengunakan Rancangan Acak Lengkap (RAL) Faktorial, dengan 2 faktor dan 3 ulangan. Faktor pertama adalah komposisi pupuk (K) yaitu : K1 = pelepah sawit + tandan kosong kelapa sawit (1:1), K2 = pelepah sawit + tandan kosong kelapa sawit (1:2) dan K3 = pelepah sawit + tandan kosong kelapa sawit (2:1). Faktor kedua adalah dosis pupuk (D): D1 = 15 ton/ha, D2 = 20 ton/ha dan D3 = 25 ton/ha. Didapat 27 satuan percobaan, setiap satuan percobaan terdiri dari 5 tanaman sehingga ada 135 tanaman percobaan yang diamati. Hasil sidik ragam yang bebeda nyata akan diuji lanjut dengan menggunakan Ducan’s Multiple Range Test (DMRT) dengan taraf uji 0,05. Hasil penelitian menyimpulkan bahwa perlakuan komposisi pupuk berpengaruh sangat nyata terhadap jumlah cabang, jumlah buah dan bobot buah. Perlakuan dosis memberikan pengaruh nyata terhadap jumlah buah umur 14 MST. Perlakuan komposisi pupuk terbaik didapatkan pada perlakuan K2 (perbandingan Pelepah sawit dan tandan kosong kelapa sawit, 1:2). Perlakuan dosis terbaik didapat pada perlakuan D3 (dosis 25 ton/ha). Kata kunci: Cabai merah (Capsicum annum L), pupuk organic, pelepah sawit, tandan kosong kelapa sawit.
