Abstract

Thailand-variety elephant grass fertilized with organic and urea combination was conducted from August 1st up to Novembre 30th, 2009. The purpose of this study was to know the best interaction of organic-urea levels on the production and quality aspects of Thailand-variety elephant grass. The method used was experimental, 3x4 factorial pattern, using completely randomized design (CRD). There were 3 replicates in each treatment combination. The first factor was organic fertilizer (3 levels: k0= 0 ton/ha, k1= 20 tons/ha, and k2 = 40 tons/ ha), and the second factor was urea (4 levels: R0 = 0 kg/ha, R1 = 150 kg/ha, R2 = 300 kg/ha, and R3 = 450 kg/ ha). Variables measured were the number of tillers, plant height, the number of leaves/bunch, fresh weight, dry weight, agronomic efficiency, and crude protein and crude fiber concentrations. The result of analisys of variance showed that organic fertilizer had significant effect (P < 0.05) on the tiller/bunch, number of leaves/bunch, dry matter yield, and crude protein, but gave highly significant effect (P < 0.01) on fresh yield, and no significant effect (P > 0.05) on the height of plant and crude fiber concentration. Whereas urea gave a significant effect (P < 0.05) on the number tiller/bunch, and highly significant effect (P < 0.01) on fresh and dry matter yield and crude protein concentration, but no significant effect (P > 0.05) on height of plant, the number of leaves to stems ratio, and crude fiber concentration. The conclusions of this study for the management of Thailand-variety elephant grass, the best organic-urea fertilizer combination was at the level of 40 tons of organic fertilizer/ha/ defoliation and 300 kg of urea/ha/defoliation, showed from the agronomy aspects such as the number of tillers/ bunch, the height of plant, the number of leaves/bunch, fresh and dry matter yields, and quality aspect include crude protein and crude fiber concentration.

Abstract

Permasalahan utama yang ditemui dalam pengawetan hijauan sumber protein menjadi silase adalah proses pembusukan akibat dari sifat buffer protein yang tinggi dalam hijauan yang mungkin berkaitan dengan rasio karbon:nitrogen (C/N) yang rendah. Penelitian ini bertujuan untuk menguji pengaruh rasio C/N dalam proses ensilage terhadap kualitas silage Chromolaena odorata yang merupakan salah satu hijauan sumber protein. Telah diuji empat perlakuan yaitu C0N = Chromolaeana tanpa penambahan sumber karbon (rasio C/N 14,9); CN20= Chromolaeana + tepung putak (Corypha gebanga) sebagai sumber karbon untuk mencapai rasio C/N 20, atau 25 (CN25) atau 30 (CN30) menggunakan prinsip rancangan acak lengkap 4 × 3. Variabel yang diamati adalah profil organoleptik, proporsi yang rusak, dan kandungan nutrisi silase. Data dianalisis menggunakan analisis varian untuk RAL dan perbedaan perlakuan ditentukan menggunakan Duncan test yang ditetapkan pada nilai Alfa 0,05. Hasil penelitian menunjukkan bahwa meninggkatkan rasio C/N hingga 30, secara nyata meningkatkan profil organoleptik, kandungan bahan organik, protein kasar, serta menurunkan komponen serat kasar dalam silase. Disimpulkan bahwa rasio C/N dalam proses pembuatan silase hijauan sumber protein sangat penting di mana hasil terbaik dicapai dalam penelitian ini adalah rasio C/N 30. Namun, belum dapat direkomendasikan sebagai rasio yang terbaik karena hingga rasio 30, tren pengaruhnya masih berbentuk linear. Kata kunci: Chromolaena odorata, rasio C/N, silase, hijauan sumber protein, nutrisi

Abstract

Forage is needed by ruminant in large quantity. Several forages have low feed quality and then it is required to improve the forage quality that generally from gramineae and leguminoseae. Biotechnology using AMF is one of good strategic management on forage. AMF from the symbiotic mutualism with host plant through it’s root, has important role in plant production, ecosystem health. The best known mycorrhizal effect is that mycorrhizal plants take up more soil phosphorus and grow faster than corresponding non-mycorrhizal control plants. While spores are considered to be the resistant structure and may be viewed as ‘long term’ propagules when viable host plants are not present, hyphae are considered to be the main source of inokula when host plants are present and the soil is not disturbed.

Abstract

Agricultural and forage land used are generally not increased even tends to decrease, therefore the land use needs to be optimized; one of them is by mean of multiple cropping system. Land management efforts through the multiple cropping systems selected is supporting the fertility of soil physical, chemical and biological. Multiple cropping systems require an appropriate plant species and a supportive environment to produce high-quality crops and availability of feed crops are sufficient throughout the year. Application of Multiple cropping system can increase the efficiency of environmental factors (sun, water and nutrients), inhibits the growth of weeds, suppress pests and diseases, save labor and improve the income of livestock farmers.Keywords: forage crops, multiple cropping systems, soil fertility

Abstract

Phosphorus (P) is one of the essential nutrients for plants that availability is strongly influenced by soil pH. In acid soils, most of the P is given will form insoluble compounds and is not available to plants. Phosphate solubilizing bacteria is a soil microorganism that can improve the provision ofP in acid soils. The study aimed to determine the effect of Phosphate solubilizing bacteria on the productivity of tropical kudzu was conducted using a completely randomized design with four treatments ie without isolate (I0), standard isolate (I1), isolate B.80.1649-1 (I2) and isolate B.80.1649-8 (I3), each treatment was repeated four times. The results showed that both isolates were isolated and selection were able to increase the length of the plants, number of leaves, shoot dry weight, root dry weight, shoot P content,  N uptake, P uptake, and production of crude protein of tropical kudzu (Pueraria phaseoloides Benth.). The ability of isolates B.80.1649-1 higher than isolates B.80.1649-8, and comparable with standard isolate.
