Abstract


Abstak. Suatu  penelitian tentang penambahan bahan pembenah tanah terhadap produktivitas dan nutrisi rumput brachiari decumbens.  Penelitian ini dilakukan di Desa Teureubeh, Kecamatan Jantho, Kabupaten Aceh Besar. Penelitian ini berlangsung selama 60 hari, mulai tanggal 20 Juni 2016 sampai 20 Agustus 2016. Serta di Laboratorium Ilmu Nutrisi Dan Teknologi Pakan Program Studi Peternakan, Fakultas Pertanian, Universitas Syiah Kuala, Darussalam Banda Aceh. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian bahan pembenah tanah pada lahan kering terhadap produktivitas dan nutrisi rumput Brachiaria decumbens.  Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas 3 perlakuan dengan 4 ulangan. Adapun perlakuan dalam penelitian ini adalah jenis pemupukan yang terdiri dari pemupukan NPK yang merupakan pemupukan dasar perlakuan sebanyak 400 kg/ha (A), biochar 10 ton/ha + NPK 400 kg/ha (B) dan pupuk kandang + NPK 400 kg/ha (C). Setiap perlakuan diulang sebanyak 3 kali sehingga diperoleh 12 unit perlakuan. Parameter yang diamati dalam penelitian ini adalah jumlah anakan, tinggi tanaman, bahan kering, protein kasar, dan serat kasar. Data yang diperoleh diolah secara statistik menggunakan analysis of variance ( ANOVA). Perbedaan antar perlakuan dinyatakan apabila (P<0,05). Hasil penelitian menunjukkan bahwa  pemberian bahan pembenah tanah pada produktivitas dan nutrisi  rumput Brachiaria decumbens, yang ditanam di lahan kering berpengaruh  sangat nyata (P<0,01) pada parameter  jumlah anakan, berat segar dan tinggi tanaman. Namun  tidak berpengaruh (P>0,05) pada persentase bahan kering, persentase protein kasar, dan persentase serat kasar rumput Brachiaria decumbens
Effect Of Variuos Use Soil Amendement On Dry Land Of Productivity And Nutrition Brachiaria Decumbens Grass Abstract. A study on the addition of soil enhancers to the productivity and nutrients of grass brachiari decumbens. This research was conducted in Teureubeh Village, Jantho District, Aceh Besar District. The study lasted for 60 days, from June 20, 2016 to August 20, 2016. As well as in the Laboratory of Nutrition Science and Feed Technology of Animal Husbandry Program, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh. This study aims to determine the effect of soil enhancement on dry land on the productivity and nutrition of Brachiaria decumbens grass. This study used a Completely Randomized Design (RAL) consisting of 3 treatments with 4 replications. The treatment in this research is kind of fertilization consisting of NPK fertilization which is fertilizing treatment base of 400 kg / ha (A), biochar 10 ton / ha + NPK 400 kg / ha (B) and manure + NPK 400 kg / ha (C). Each treatment was repeated 3 times to obtain 12 treatment units. Parameters observed in this study were number of tillers, plant height, dry matter, crude protein, and crude fiber. The data obtained were processed statistically using analysis of variance (ANOVA). Differences between treatments are expressed when (P <0.05). The results showed that the provision of materials. The results showed that the provision of soil enhancers on the productivity and nutrients of Brachiaria decumbens grasses, which were planted in dry land had significant effect (P <0.01) on the parameter of number of tillers, fresh weight and plant height. However no effect (P> 0.05) on dry matter percentage, percentage of crude protein, and percentage of coarse grass fiber Brachiaria decumbensAbstract.
