Optimasi Pupuk Kandang Ayam (Broiler) dalam Mendukung Produktivitas Rumput Brachiaria humidicola (Rend.) Sch di Unit Pendidikan dan Penelitian Peternakan Jonggol (UP3J)

Abstract

Penelitian ini bertujuan untuk mengukur dosis pupuk kandang ayam yang memberikan hasil yang terbaik terhadap produktivitas rumput Brachiaria humidicola. Penelitian ini dilaksanakan di Unit Pendidikan dan Penelitian Peternakan Jonggol (UP3J). Penelitian dilakukan dengan menggunakan rancangan acak lengkap dengan pola petak terbagi (RAL split plot) dengan 5 perlakuan dan 4 ulangan, yaitu P1 = urea 150 kg ha-1, P2 = 5 ton ha-1 pupuk kandang ayam + urea 75 kg ha-1, P3 = 10 ton ha-1 pupuk kandang ayam + urea 75 kg ha-1, P4 = 15 ton ha-1 pupuk kandang ayam + urea 75 kg ha-1 dan P5 = 20 ton ha-1 pupuk kandang ayam + urea 75 kg ha-1. Hasil penelitian menunjukkan pupuk kandang ayam efektif meningkatkan jumlah tunas, jumlah stolon, panjang stolon, tinggi tanaman, produksi biomassa individu tanaman, warna tanah serta warna daun rumput Brachiaria humidicola. Dosis optimal dalam mendukung produktivitas rumput Brachiaria humidicola sebesar 20 ton ha-1 pupuk kandang ayam dan 75 kg ha-1 pupuk anorganik urea. Peningkatan dosis pupuk kandang ayam berkorelasi positif terhadap produksi biomassa rumput Brachiaria humidicola.

The aim of this research were to measure the dose of chicken manure fertilizer that gives the best results on the productivity of Brachiaria humidicola. These experiment were conducted at Jonggol Animal Science Teaching and Research Unit (JASTRU). This research was designed by using split-plot design with 5 treatments and 4 replications, namely P1 = urea 150 kg ha-1, P2 = 5 tons ha-1 of chicken manure fertilizer + urea 75 kg ha-1, P3 = 10 tons ha-1 of chicken manure fertilizer + urea 75 kg ha-1, P4 = 15 tons ha-1 of chicken manure fertilizer + urea 75 kg ha-1 and P5 = 20 tons ha-1 of chicken manure fertilizer + urea 75 kg ha-1. The results showed that chicken manure fertilizer was effective in increasing the number of shoots, number of stolons, stolon length, plant height, individual plant biomass production, soil color and leaf color of Brachiaria humidicola. The optimal dose to support the productivity of Brachiaria humidicola is 20 tons ha-1 of chicken manure fertilizer and 75 kg ha-1 of urea. Increasing the dose of chicken manure fertilizer was positively correlated to the biomass production of Brachiaria humidicola.
