Abstract

Papua Barat merupakan daerah yang sangat potensial bagi pengembangan ternak sapi potong dan/atau usaha peternakan sapi bali karena wilayahnya yang luas dan cukup tersedia sumberdaya hijauan lokal sebagai pakan ternak. Padang penggembalaan alam merupakan sumber hijauan pakan bagi ternak ruminansia terutama oleh peternakan rakyat di daerah pedesaan. Penelitian ini bertujuan untuk menganalisis komposisi botani dan persebaran jenis-jenis hijauan lokal di areal padang penggembalaan alam di dataran Kebar kabupaten Tambraw provinsi Papua Barat. Komposisi botani dianalisis dengan metode dry weight rank yaitu menaksir komposisi botani bahan kering tanpa melakukan pemotongan dan pemisahan spesies hijauan dan mengobservasi hanya tiga jenis hijauan yang mempunyai kontribusi besar, dan menetapkannya sebagai ranking 1, 2, dan 3. Persebaran jenis-jenis hijauan lokal dengan menginventarisir semua spesies yang ditemukan, dihitung frekuensi mutlak dan frekuensi relatif jenis. Komposisi botani dan persebaran jenis ditetapkan dengan metode cuplikan menggunakan kuadran berukuran 1 m2. Hasil penelitian menunjukkan bahwa padang penggembalaan alam dengan komposisi botani sekitar 82 – 87% rumput, 1% legum dan hijauan yang dapat dikonsumsi dan 12 - 17% hijauan lain yang tidak dapat dikonsumsi ternak. Ditemukan sebanyak 40 spesies hijauan pada padang penggembalaan alam di dataran Kebar.

Abstract

This paper aims to provide an overview of the potential forage production, nutrients and antinutrients chemical composition, and the potential development of Sudan grass (Sorghum sudanense) in eastern part of Indonesia, particularly in the Papua island as a local forage ruminant. Local forage is very potential to be developed in Papua island, because it adapts to dry land and drought resistant, capable of growing back, and is very responsive to fertilizer and irrigation, as well as can be growth either in lowland and highland. Nitrogen, phosphorus and potassium fertilizer treatments have significant effect to dry matter and organic matter productions of Sudan grass with their level dosage recommendations are 300 kg N/ha, 300 kg P/ha, and 150 kg P/ha, respectively. Keywords: sudan grass, fertilizer, forage production, nutrient and antinutrition

Abstract

The aim of this study were to obtain the optimum level of NPK fertilizers of sudan grass and economic of NPK fertilizers utilization. The randomized completely block design (RCBD) were used to evaluate, namely 4 levels of fertilizer doses NPK and 4 blocks for determine the grass production. The treatments for randomly N application, namely: No (PO); N150 (P1); N300 (P2); and N450(P3). Phosphorus and K fertilizer were given at the same rate, that were 300 kg P2O5 and 150 kg K2O ha-1. The results of study showed that DM production for PO (3.19 tonha-1) differed significantly with P1, P2 and P3; but between P2 and P3 did not differ significantly. There were increased DM production due to increasing of fertilizers applied. The values of DM production increasing percentage for P1, P2, and P3 compared with PO, for DM were 69.44%, 80.45% and 85.28%, respectively. The increased percentages of DM production of P3 tended to decrease. Therefore, it can be summarized that P2 (300 kg N, 300 kg P and 150 kg K ha-1) was optimum level for DM production. Based on partial budget analysis, indicated that cultivation of sudan grass with NPK fertilizer treatments yielded profit positively. The profit value for P1, P2, and treatment of P3 were Rp 581.500,-; Rp 2.009.500,-; and Rp 2.997.500,-per hectare, respectively.

Abstract

The aim of this study were to obtain the dry matter (DM) production of sudan grass at second harvest under different plant distances without nitrogen fertilization and to decide whether fertilization have to be added or not. The design of the study was split plot design 4 x 7 with three blocks. The main plots were plant distances, namely :20x40 cm (J1), 40x40 cm(J2), 60x40 cm (J3) and 80x40 cm (J4), and each plot was divided into 7 subplots for randomly N application treaments, namely :N0 (P0); N75 (P1); N150 (P2); N225 (P3); N300 (P4); N375 (P5) dan N450 (P6). Phosphorus and K fertilizer were given at the same rate, that were 300 kg P2O5 and 150 kg K2O. Result of the study showed that planting distances, level of fertilizers and the interaction were significant (P<0.05) affected DM production and height of plants in the second harvest. The DM production in the second harvest was significantly lower (P<0.05) than the DM production in the first harvest. From this study it can be concluded that N fertilizer application should be given again after cutting in order to maintain the DM production of sudan grass in the next harvest.

Abstract

This study aims to determine the effect of inorganic fertilizer, organic fertilizer, and the combination of both on the growth of king grass (Pennisetum purpurephoides). The research method was a completely random design with 4 treatments and 5 replications. The research treatments consisted of A (without fertilizer), B (100% inorganic fertilizer), C (100% organic fertilizer), and D (50% inorganic and 50% organic fertilizer). The result of the study shows that inorganic, organic, and its fertilizer combination treatment has a non-significant effect on the height of the plant, the length and width of the leaf, and the length of its segments, while inorganic and organic fertilizer treatment has a significant effect on the stem diameter. The conclusion is that the use of 100 % organic fertilizer has better results for the vegetative growth of king grass (Pennisetum purpurephoides) compared to the use of inorganic fertilizer and its combination.
