Abstract

Kacang tanah merupakan salah satu jenis tanaman pangan yang ditanam di lahan kering, namun produksinya masih rendah akibat faktor kesuburan tanah yang rendah. Penelitian ini bertujuan untuk mengetahui efek dosis pupuk kotoran ayam terhadap pertumbuhan dan hasil kacang tanah pada berbagai variasi jarak tanam. Penelitian dilakukan dengan menggunakan Rancangan Acak Kelompok Faktorial (RAKF), yaitu perlakuan dosis pupuk kotoran ayam, terdiri dari 5 ton/ha (P1), 7,5 ton/ha (P2), 10 ton/ha (P3); dan perlakuan jarak tanam yang terdiri dari 20 cm x 20 cm (J1), 20 cm x 30 cm (J2), 20 cm x 40 cm (J3). Hasil penelitian menunjukkan bahwa dosis pupuk kotoran ayam memberikan pengaruh yang relatif sama terhadap semua peubah, sedangkan perlakuan jarak tanam 20 cm x 40 cm memberikan pengaruh terbaik terhadap jumlah cabang, berat polong bernas, dan jumlah polong bernas dan perlakuan jarak tanam 20 cm x 20 cm memberikan pengaruh terbaik pada produksi polong per petak. Sementara itu, interaksi perlakuan yang nyata hanya diperoleh pada peubah umur berbunga, dengan umur berbunga paling lambat pada kombinasi perlakuan P3J3.

Abstract

Oil palm plants (Elaeis guineensis Jacq.) are one of Indonesia's leading commodities which have quite high productivity as a producer of vegetable oil, as well as being a source of foreign exchange for the country and employment for the community. The aim of the study was to determine the effect of urea, KCl and chicken manure on the growth of oil palm seedlings. The research location was conducted on Jalan Tapak Lebar I Rt.04, Sidorejo Village, Lubuklinggau Barat II District, Lubuklinggau City, South Sumatra, from September to December 2024. Treatment P1 = No treatment, P2 = Urea fertilizer 5 g/plant, P3 = KCl fertilizer 5 g/plant, P4 = Chicken manure 250 g/plant, P5 = Urea fertilizer 5 g + KCl 5 g/plant, P6 = Urea fertilizer 5 g + chicken manure 250 g/plant, and P7 = KCl fertilizer 5 g + chicken manure 250 g/plant. Each sample treatment consisted of 3 seedlings and was repeated 3 times. Using a non-factorial Completely Randomized Design (CRD), Duncans Multiple Range Test (DMRT). The administration of urea fertilizer at a dose of 5 g/plant and chicken manure at a dose of 250 g/plant gave the best effect on all observation variables, namely: increase in height, increase in the number of leaf stalks, stem diameter, number of leaflets, length of leaflets.
