Abstract

Rumput odot (Pennisetum purpureum cv. Mott) merupakan salah satu jenis rumput gajah yang mulai dikembangkan. Rumput ini dapat tumbuh pada berbagai macam tanah dan sangat responsif terhadap pemupukan. Untuk mendukung produktivitas hijauan tentunya dapat memanfaatkan pupuk kandang ternak seperti sludge (lumpur biogas) sebagai pupuk. Penggunaan feses ternak sebagai pupuk hayati yang murah dan ramah lingkungan merupakan alternatif yang perlu dikembangkan sehingga ada timbal balik antara ternak dan hijuaan pakan. Dengan demikian, pemenuhan hara tanah akan tercukupi secara berkesinambungan dan dapat menunjang pertumbuhan serta produksi hjauan dalam rangka penyediaan hijauan pakan ternak. Penelitian ini bertujuan mengevaluasi pertumbuhan dan produktsi rumput Odot (Pennisetum purpureum cv. Mott) dengan beberapa macam pupuk (pupuk kandang sapi, kambing, sludge digester biogas dan urea). Penelitian dilakukan di lahan produksi hijauan pakan laboratorium lapang Jurusan Peternakan Universitas Bengkulu. Rancangan yang digunakan dalam penelitian ini adalah rancangan acak lengkap (RAL) dengan 5 perlakuan P0 (Kontrol), P1 (pupuk urea), P2 (pupuk kandang sapi), P3 (pupuk kandang kambing), dan P4 (pupuk lumpur biogas) untuk setiap perlakuan terdiri dari 4 ulangan. Variabel yang diamati meliputi pertumbuhan dan produksi rumput Odot segar maupun bahan kering (BK). Data yang diperoleh dianalisa dengan sidik ragam (anova), bila berpengaruh nyata dilakukan uji Duncan’s Multiple Range Test (DMRT). Hasil penelitian menunjukan perlakuan tidak berpengaruh nyata (P>0,05) terhadap tinggi tanaman, lebar daun, jumlah anakan, produksi segar dan produksi bahan kering batang rumput Odot. Produksi BK batang dari P0 - P4 berturut turut sebesar 50,66; 69,02; 57,30; 99,66 dan 65,31 g/petak serta produksi bahan kering daun berturut turut P0 - P4 sebesar 175,75; 22,43; 195,63; 274,46 dan 231,12 g/petak. Pada umur tanaman 35 hari setelah tanam (hst) perlakuan berpengaruh nyata (P<0,05) terhadap panjang daun. Persentase produksi bahan kering batang berturut turut P0 - P4 sebesar 22,07; 23,65; 22,60; 26,52 dan 22,25 %, yang mana pada persentase produksi bahan kering (BK) batang P1 dan P3 nyata (P<0,05) lebih tinggi dibandingkan dengan P0, P2 dan P4, sebaliknya persentase produksi bahan kering (BK) daun berturut turut P0 - P4 sebesar 77,93; 76,36; 77,40; 73,48 dan 7,75 %, persentase produksi bahan kering daun P1 dan P3 nyata (P<0,05) lebih rendah dibandingkan dengan P0, P2 dan P4. Penelitian ini dapat disimpulkan pengunaan berbagai jenis pupuk (pupuk kandang kambing, pupuk kandang sapi, limbah istalasi biogas dan urea), ternyata tidak mempengaruhi produktivitas rumput odot yang dipotong/panen pada umur 63 hari setelah tanam.

Tris Akbarillah, MP and Dr. Irma Badarina, S.Pt., MP, 2017, 33 pages). The odot grass (Pennisetum purpureum cv. Mott) is one of the elephant grass species that was developed. This grass can grow on a variety of soils and is very responsive to fertilization. To support the productivity of forage can certainly use cattle manure such as sludge (biogas mud) as fertilizer. The use of livestock feces as a cheap and environmentally friendly biological fertilizer is an alternative that needs to be developed so that there is a tradeoff between livestock and feeding forage. Thus, the nutrient fulfillment of the land will be sustained continuously and can support the growth and production of forage in order to provide forage of animal feed. This study aims to evaluate the growth and productivity of Odot grass (Pennisetum purpureum cv. Mott) with several kinds of fertilizer (cow manure, goat, sludge digester biogas and urea). The research was conducted at field forage production in field laboratory of Animal Husbandry Department at University of Bengkulu. The design used in this study was a complete randomized design (RAL) with 5 treatments P0 (Control), P1 (urea fertilizer), P2 (cow manure), P3 (goat manure), and P4 (biogas mud fertilizer) for each. The treatment consisted of 4 replications. Variables observed were growth and production of fresh and dry Odot grass (dry matter). Data obtained were analyzed by anova, any significant differences found then was further analyzed by Duncan's Multiple Range Test (DMRT). The results showed no significant effects (P> 0.05) on plant height, leaf width, number of tillers, fresh production and Odot grass dry matter production. Production of stem DM from P0 - P4 were 50.66; 69.02; 57.30; 99.66 and 65.31 g / plots, respectively and the production of dry matter leafs consecutively P0 - P4 were 175.75; 22.43; 195.63; 274.46 and 231.12 g / plot. At plant age 35 days after planting (hst) treatment had significant effect (P <0.05) to leaf length. Percentage of P0 - P4 dry sterilized production of 22.07; 23.65; 22.60; 26.52 and 22.25%, which in percentage of dry matter (DM) stems P1 and P3 (P <0.05) were higher than P0, P2 and P4, whereas the percentage of leaf dry matter (DM) of P0 - P4 were 77.93; 76,36; 77,40; 73.48 and 7.75%, respectively. The percentage of actual dry matter of P1 and P3 leaves (P <0.05) were lower than that of P0, P2 and P4. This research concluded that the use of various types of fertilizer (goat manure, cow manure, biogas and urea wastewater), did not affect the productivity of the cut / harvested grass at 63 days after planting.
