The influence of EDTA on the accumulation, movement, and distribution of cadmium in dwarf elephant grass

This research intended to determine the effect of palm oil tree shade and mixed planting on grass and leguminous on productivity. This research has been done on March—June 2018 in Tanjung Agung Area, Katibung District, Kalianda, South Lampung. This research used Completely Randomized Design (CRD) with split plot design method. The treatment was implemented in this research is (1) shading, consist of two levels, which are N0 (without shade) and N1 (palm oil tree shade) and (2) mixed plant species, consist of two variations; which is A1 (elephant grass and purple bush bean) and A2 (dwarf elephant grass and purple bush bean). The data which obtained were analyzed by analysis of variance on 5% significant level, then if the result significantly difference, it were analyzed with Duncan Multiple Range Test (DMRT). The results showed that palm oil shading has not significant effect on grass productivity. there is an interaction between the type of grass and oil palm shade on the number of elephant grass and odot grass tillers. The dry matter of grass on mixed planting on land without shade was significantly different with dry matter of grass on mixed planting in palm oil shade. However, it has tendency to increase organic matter of grasss on palm oil shade. Keywords: Palm Oil Shade, Elephant Grass, Dwarf Elephant Grass, Mixing Grass, Productivity

Dwarf Elephant Grass

Coconut plantation area in North Sulawesi is an ecological basis for cattle but lower in terms of productivity of feed d annutrients. This study aims to improve the productivity of feed and nutrient for beef cattle development in the coconut palm plantation through the introduction of superior forage P. purpureum Schum cv. Mott. The study was conducted from July 2012 to January 2013, in the Ongkaw Village, South Minahasa Regency, North Sulawesi. Coconut palms used in this study was 50 years-old tall coconuts with planting system of 9 m x 9 m at farmer plantation area. The research followed a completely randomized design with three treatments and three replications. The treatments tested were types of animal feed, which consists of (1). P. purpureum Schum cv. Mott (dwarf elephant grass), Cynodon sp. (native grass), and P. purpureum (forage elephant grass). Planting systems of livestock forage are 20 cm x 20 cm, for Cynodon sp. 100 cm x 50 cm for both P. purpureum Schum cv. Mott and P. purpureum. The first defoliation was done 70 days after planting, after that, the defoliation was done every 45 days. The result showed that the dry weight of animal feed/ha was 15.31 tons, 163.73 tons and 128.21 tons for Cynodon sp., P. purpureum Schum cv. Mott and P. purpureum, respectively. Dry matter and nutrients of P. purpureum Schum cv. Mott was higher than that of Cynodon sp. and P. purpureum. The result showed that the introduced P. purpureum Schum cv. Mott significantly increased both animal feed production and feed nutrients in coconut plantation area as compared to the local forage crops (Cynodon sp. and P. purpureum). The P. purpureum Schum cv. Mott can adapt to the shade of bearing coconut palms.ABSTRAK Lahan perkebunan kelapa di Sulawesi Utara merupakan basis ekologi sapi namun produktivitas dan nutrisi pakan rendah. Penelitian ini bertujuan meningkatkan produktivitas pakan dan nutrisi untuk pengembangan sapi potong di lahan perkebunan kelapa, melalui introduksi hijauan pakan ternak unggul Pennisetum purpureum Schum cv. Mott. Penelitian dilaksanakan pada Juli 2012 sampai dengan Januari 2013 di Desa Ongkaw, Kabupaten Minahasa Selatan, Provinsi Sulawesi Utara. Tanaman kelapa yang digunakan dalam penelitian ini adalah Kelapa Dalam umur 50 tahun dengan jarak tanam 9 m x 9 m. Penelitian menggunakan Rancangan Acak Lengkap dengan tiga perlakuan dan tiga ulangan. Tiga perlakuan yang diuji adalah jenis pakan ternak, yang terdiri atas P. purpureum Schum cv. Mott, Cynodon sp. dan Pennisetum purpureum. Jarak tanam pakan ternak tersebut adalah 20 cm x 20 cm untuk Cynodon sp., dan 100 cm x 50 cm untuk P. purpureum Schum cv. Mott dan P. purpureum. Defoliasi pertama dilakukan 70 hst, setelah itu defoliasi dilakukan setiap 45 hari. Hasil penelitian ini menunjukkan bahwa berat kering pakan ternak per ha adalah 15,31 ton; 128,21 ton; dan 163,73 ton/ha berturut-turut untuk Cynodon sp., P. purpureum, dan P. purpureum Schum cv. Mott. Bahan kering dan nutrisi pakan P. purpureum Schum cv. Mott lebih tinggi dari Rumput Cynodon sp. dan Pennisetum purpureum. Hasil penelitian menunjukkan bahwa P. purpureum Schum cv. Mott yang diindtroduksi meningkatkan produksi dan nutrisi pakan ternak pada lahan perkebunan kelapa secara nyata dibanding tanaman pakan lokal Cynodon sp. dan P. purpureum. Pennisetum purpureum Schum cv. Mott dapat beradaptasi di bawah naungan kelapa dewasa.

Dwarf Elephant Grass

Relatively short grazing periods in a pure legume pasture can be an alternative for increasing animal performance in medium-quality tropical pastures. Thus, the aim was to evaluate the herbage intake and animal performance of steers grazing dwarf elephant grass (Pennisetum purpureum Schum. cv. BRS Kurumi) with two access times [2 h (07:00 - 9:00) and 6 h (07:00 - 13:00)] to an area of forage peanut (Arachis pintoi cv. Amarillo). Twelve steers (219 ± 28.8 kg LW) were divided into four groups and assessed during three consecutive grazing cycles, from January to March 2013. The crude protein and neutral detergent fiber contents were 158 and 577 g/kg dry matter (DM) for dwarf elephant grass and 209 and 435 g/kg DM for forage peanut, respectively. The pre-grazing height and leaf mass of dwarf elephant grass and forage peanut were 94 cm and 2782 kg DM/ha and 15 cm and 1751 kg DM/ha, respectively. The herbage intake (mean = 2.7 ± 0.06% LW) and average daily weight gain (mean = 1.16 ± 0.31 kg/day) were similar for both treatments. However, animals with 2-h access to the legume paddock grazed for 71% of the time, whereas those with 6-h access grazed for 48% of the time. The performance of the steers that were allowed to graze forage peanut pasture for 2 h is similar to that of those that were allowed to graze the legume pasture for 6 h.
