Abstract

Grasses are known as part of palm plantation ecology and has benefits as source of ruminant feed. Besides, it is believed to have ability as Carbon Storage. However, to what extent the grass can be capable as Carbon Storage and what are the species that can be best fitted as Carbon Storage are still questionable especially for those that are grown on plantation. Thus, investigation was carried out to identify tropical grasses grown under palm plantation coverage that can be functioned as Carbon Storage as well as to determine its nutrition contents. Due to having many traditional plantations, Pauh District of Sarolangon Jambi was opted as observation area. From there, samples were taken randomly from plots and sub-plots that were pre-created. Grass samples are grouped into three groups; leave, stem and root, and taken to laboratory for analysis. Among those that were observed, Panicum brevifolium, Axonopus compressus, Centotheca longilamina, Centotheca longilamina ohwi and Schleria sumatrensis were shown their capability as carbon storage. However, those are carbon storage capable have slightly different in carbon and nitrogen contents, Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) analysis and almost the same in fiber fractions.

Abstract

The aimed of this experiment was to investigate the effect phosphorus-enriched compost fertilizer with P solubilizing microorganisms on the growth of Setaria splendida. The experiment was designed in completely randomized designed with 4 treatments, consisted of R0 = Rock phosphate, R1 = Rock phosphate + rice straw + chicken manure, R2 = Rock phosphate +  rice straw + chicken manure + Trichoderma harzianum. R3 = Rock phosphate + rice straw+ chicken manure + Aspergillus niger. Preparation of phosphorus-enriched compost was modified from Bangar et al. (1989); Biswas (2008) with the dosage of aplication based on Apniyarni, (2003) and Dewi (2002). Physical and chemical characteristics of phosphorus-enriched compost fertilizer and the growth of S. splendida were observed in this experiments. The results showed that phosphorus- enriched compost fertilizer with and without P solubilizing microorganisms resulted good physical and chemical characteristics. The growth of S. splendida did not significantly different for phosphorus-enriched compost with and without P solubilizing microorganism treatments. Application of enriched phospho-compost fertilizer with and without P solubilizing microorganisms significantly increased the growth of S. splendida compared to control (rock phosphate).

Abstract

Herbaceous forages in plantation system could be categorized into two groups that are  native and introduction species. These groups are species which have adaptability to ecophysiological condition as the growth of plantation trees. Some of these native species have multi functions/benefits. Inspite of as forage with good quality properties and used as amandement, these forage have nutraceuticals (phytochemical) function; it has active compound which roles as curing and preventing disease and also as pesticide. These active compounds may be formed as alkaloids, flavonoids, saponin and tannin. These active compound also found in introduction species such as Arachis pintoi which known have active compound from alkaloids and flavonoids that roles as antimicrobial/ natural pesticide which come from root and as antioxidant which found in leaves. The latest research found that there is an increase of these active compounds by arbuscular mycorrhizal fungi inoculation. This fungi known has benefits for enhancement root system and nutrient absorbtion for plant in integration system.

Abstract

Ukuran bibit merupakan salah satu cerminan mutu bahan tanaman yang akan menghasilkan produktivitasyang baik jika kebutuhan akan hara untuk pertumbuhannya terpenuhi melalui pemupukan. Penelitian ini bertujuan untuk mengetahui pengaruh ukuran bibit dan pupuk anorganik terhadap pertumbuhan kelor (Moringa oleifera). Penelitian menggunakan rancangan acak lengkap pola faktorial 3x3 dengan 3 ulangan. Faktor pertama adalah ukuran bibit (kecil, sedang dan besar) dan faktor kedua adalah pupuk anorganik (N; N dan P; serta N, P dan K). Ukuran bibit meningkatkan tinggi tanaman pada panen kedua dan jumlah tunas pada panen pertama dipengaruhi oleh ukuran bibit dan penerapan pupuk anorganik pada Moringa oleifera. Sementara itu, tidak terdapat interaksi antara ukuran bibit dan pupuk anorganik terhadap seluruh peubah yang diamati. Disimpulkan bahwa ukuran bibit sedang dan besar dan pemupukan dengan kombinasi lebih dari satu unsur hara (kombinasi N, P dan N, P dan K) menghasilkan pertumbuhan yang terbaik pada Moringa oleifera. Kata kunci: Moringa oleifera, pupuk anorganik, ukuran bibit, pertumbuhan tanaman

Abstract

Penelitian bertujuan untuk mengetahui pengaruh pemberian biskuit konsentrat pakan mengandungIndigofera dan sengon terhadap konsumsi ransum, dan irisan komersial karkas kambing PE. Penelitianini dilaksanakan di Farm Fakultas Peternakan Universitas Jambi. Rancangan percobaan yang digunakanpada penelitian ini yaitu Rancangan Acak Kelompok (RAK) dengan 2 perlakuan dan 10 ulangan.

Abstract

This experiment was aimed to reveal the effect of seed physical scarification and various growing mediaon vigor of Moringa oleifera. This study was conducted in greenhouse and consisted of two phases ofexperiment; first was studied the effect of physical scarification on seed germination of M. oleifera and thesecond was studied the effect of seed physical scarification and various sub optimum growing media onvigor of M. oleifera. The germination test was arranged in randomized completely design with 4 treatmentsthat were P0 = non scarification, P1 = one side scarification, P2 = two sides scarification, and P3 = full sidescarification. The variables measured were germination percentage (%) and seedling dry weight (g/plant).The second study was arranged in a factorial randomized completely design with the four treatments ofscarification (P0, P1, P2 and P3) over six growing media (sands, bricks, bricks and sands mixture, bricksand soils mixture, soils and sands mixture, and soils). The variables observed were petioles number, plantheight (cm/plant), and plant dry weight (g/plant). The scarification was significantly affect (P<0.05) thegermination percentage and seedling dry weight. Scarification and growing media also affected the vigorof M. oleifera significantly (P<0.05). Two side seed scarification improve the germination and seedling dryweight instead of control. Combination of scarification in two sides and growing media of soils and sandsmixture given the highest vigor of M. oleifera reflected on petioles number, plant height, and plant dry weight.
