Pertumbuhan dan Produktivitas Tanaman Sambung Nyawa (Gynura procumbens) di Tanah Latosol dengan Penambahan Pupuk Kandang Ayam Petelur

Abstract

Penelitian ini bertujuan mengevaluasi pertumbuhan dan produktivitas tanaman sambung nyawa (Gynura procumbens) yang diberi pupuk kandang ayam petelur dengan dosis yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 10 ulangan. Perlakuan terdiri atas P0 = kontrol (5 kg tanah/polybag), P1 = P0 + pupuk kandang ayam 10 ton ha-1, P2 = P0 + pupuk kandang ayam 20 ton ha-1, dan P3= P0 + pupuk kandang ayam 30 ton ha-1. Peubah yang diamati meliputi tinggi tanaman, jumlah daun, jumlah cabang, diameter batang, luas pucuk dan daun, bobot segar, bobot kering, dan kandungan nutrien. Hasil penelitian menunjukkan bahwa penambahan pupuk kandang ayam petelur meningkatkan tinggi tanaman, jumlah daun, diameter batang, luas daun, serta total biomassa segar dan kering (p<0,05). Penambahan pupuk kandang ayam petelur secara signifikan meningkatkan kandungan abu dan serat kasar daun sambung nyawa, tetapi kandungan protein kasar tetap relatif konstan antar perlakuan. Penambahan pupuk kandang ayam petelur dengan dosis 30 ton ha-1 memberikan hasil terbaik terhadap pertumbuhan dan produktivitas tanaman sambung nyawa.

This study aimed to evaluate the growth and productivity of sambung nyawa (Gynura procumbens) plants treated with different doses of laying hen manure. This study used Completely Randomized Design (CRD) with 4 treatments and 10 replications. The treatments consisted of P0 = Control (5 kg of soil/polybag), P1 = P0 + 10 ton ha-1 of laying hen manure, P2 = P0 + 20 ton ha-1 of laying hen manure, and P3 = P0 + 30 ton ha-1 of laying hen manure. The variables observed included plant height, number of leaves, number of branches, stem diameter, shoot and leaf area, fresh weight, dry weight, and nutrient content. The results showed that the addition of laying hen manure increased plant height, number of leaves, stem diameter, leaf area, and total fresh and dry biomass (p<0.05). The addition of laying hen manure significantly increased the ash and crude fiber content of sambung nyawa leaves, but the crude protein content remained relatively constant between treatments. The addition of laying hen manure at a dose of 30 tons ha-1 gave the best results for the the growth dan productivity of sambung nyawa plant.
