Evaluasi Pertumbuhan dan Produksi Sambung Nyawa di Tanah Latosol dengan Dosis Pupuk Kandang Sapi Potong yang Berbeda

Abstract

Penelitian ini bertujuan mengevaluasi pertumbuhan dan produksi sambung nyawa dengan dosis pupuk kandang sapi yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan pupuk dan 10 ulangan. P0 = tanah latosol (kontrol), P1 = tanah latosol + pupuk kandang sapi 10 ton ha-1 (25 g polybag-1), P2 = tanah latosol + pupuk kandang sapi 20 ton ha-1 (50 g polybag-1), P3 = tanah latosol + pupuk kandang sapi 30 ton ha-1 (75 g polybag-1). Peubah yang diamati yaitu tinggi tanaman, jumlah cabang, jumlah daun tanaman diameter batang, luas pucuk dan daun, berat segar pucuk, berat kering pucuk, berat segar daun, berat kering daun, berat segar batang edible, serta berat kering batang edible. Data pengamatan dianalisis dengan Analysis of Variance (ANOVA) dan uji lanjut Duncan pada taraf 5%. Hasil penelitian petumbuhan dan produksi tanaman sambung nyawa meningkat seiring dengan penambahan dosis pupuk kandang sapi. Pertumbuhan dan produksi tanaman sambung nyawa menghasilkan nilai terbaik pada pemberian pupuk kandang sapi dengan dosis 20-30 ton ha-1.

This research aimed to evaluate the growth and production of Gynura procumbens under different doses of cattle manure. The research was conducted using Completely Randomized Design (CRD) with three fertilizer treatments and ten replications. P0 = latosol soil (control), P1 = latosol soil + 10 ton ha-1 cattle manure (25 g polybag-1), P2 = latosol soil + 20 ton ha-1 cattle manure (50 g polybag-1), P3 = latosol soil + 30 ton ha-1 cattle manure (75 g polybag-1). The observed variables included plant height, number of branches, number of leaves, stem diameter, shoot and leaf area, fresh and dry shoot weight, fresh and dry leaf weight, fresh and dry edible stems. Data were analyzed using Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test as a 5% significance level. The results showed that the growth and production of Gynura procumbens increased with the addition of cattle manure doses. The best growth and production were obtained with the application of cattle manure at doses of 20-30 tons ha-1.
