Abstract

ABSTRACTThis study was done at the glass house of University of Diponegoro, Semarang. The research was about investigating the performance of Lemna minor from Lemna spp. of Lemnaceae family when grown for 14 days under 3 different manure types and concentration levels. The beef cattle manure, chicken manure and dairy cattle manure were mixed with 30 liters tap water in a triplicate media concentration of 0g/l, 5g/l and 10 g/l. In addition to the manures 1 kg top soil was added in all experimental units and 20 g of Lemna minor was planted as the initial plant weight. The manure type and manure concentration level were arranged in a 3x3 factorial completely randomized design arrangement and mean comparisons was done with Duncan Multiple Range Test. The results in ANOVA showed that there was significant interaction (F=6.31, p=.0023) as well as significant main effects (F=21.51, p=.0001; F=52.78, p=.001) for FY. For the GR the manure type x concentration level interaction was significant (F=6.30, p=.0024) and type of manure and level of concentration main effects were also significant (F=21.45, p=.0001; F=52.63, p=.0001). Significant interaction was also noticed for CPC (F=28, p=.0001) and significant main effects of manure and concentration (F=72.64, p=.0001; F=29.12, p=.0001). The average pH of the manure solutions before planting and after harvesting was 6.07 and 6.48 respectively. Prior to preparing the mediums duplicate samples of various manure as well as top soil were tested for Kjeldahl Nitrogen on dry matter basis.Key words: Lemnaceae, Lemna minor, Lemna spp., manure

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui kecernaan dan fermentabilitas dari hijauan orok-orok yang ditanam secara tumpangsari dengan jagung manis secara in vitro dengan perbedaan kepadatan dan pola tanam. Penelitian ini menggunakan rancangan acak kelompok (RAK) pola faktorial 3 x 2 dengan 4 ulangan. Kepadatan (K) sebagai faktor pertama (6, 12, 18 tanaman/m2 diantara tanaman jagung) dan pola tanam (P) sebagai faktor kedua (1 dan 2 baris tanaman orok-orok diantara tanaman jagung, jarak tanam 100 x 25 cm). Parameter yang diamati adalah KcBK, KcBO, produksi VFA dan konsentrasi NH3. Hasil penelitian menunjukkan bahwa dengan pola tanam satu maupun dua baris dan kepadatan yang semakin meningkat tidak menurunkan KcBK, KcBO, produksi VFA secara nyata, namun menurunkan konsentrasi NH3 (P<0,05). Rerata nilai KcBK pada penelitian adalah 44,63% ± 48,09%. Rerata KcBO 49,35% ± 52,07%. Rerata produksi VFA 126,26 mM ± 136,25 mM. Peningkatan kepadatan 6 ke 12 tanaman/m2 tidak menurunkan NH3 namun nyata (P<0,05) dan konsentrasi NH3 menurun dari kepadatan dari 12 ke 16 tanaman/m2. Rerata NH3 6,06 mM ± 7,06 mM. Simpulan dari penelitian ini adalah pola tanam tidak mempengaruhi kualitas nutrisi secara nyata dan peningkatan kepadatan sampai 12 tanaman/m2 tidak mempengaruhi nilai kecernaan dan fermentabilitas.Kata kunci: tumpangsari; kecernaan; produksi; in-vitro ABSTRACT This research was conducted to evaluate the digestibility and in-vitro fermentability of orok-orok forage yielded in intercropping with sweet corn within different densities. A Completely Randomized Block Design (CRBD) was applied in 3 x 2 factorial and 4 replications. The first factor was plant density factor (6, 12, 18 plants/m2) among corn crops and the second one was line number of orok-orok (1 and 2) among corn plants, spacing 100 cm x 25 cm. The digestibility of Dry Matter (DoDM), the Digestibility of Organic Materials (DoOM), the production of volatile fatty acids (VFA) and the concentration of ammonia (NH3) were measured on fodder of orok-orok. Different plant lines of orok-orok with increasing density did not influence the DoDO, DoDM, and VFA, the value were 44.63% ± 48.09%; 49,35% ± 52.07%; 126.26 mM ± 136,25 mM; but decreased (P<0,05) the concentration of NH3, average value was 6.06 mM ± 7.06 mM. It can be concluded that neither line number of orok-orok plant nor the plant density up to 12/m2 of orok-orok plant in an intercropped system with corn plant influenced their nutrional quality as well as digestability and fermentability.Keywords: intercropping; digestibility; production; in-vitro

ABSTRACTThe study aimed to determine the effect of nitrogen fertilization and defoliation of different height to the leaf stem ratio, shot root ratio and crude fiber content in alfalfa plants (Medicago sativa). This research used factorial randomized block design (FRBD) 4x2 with 3 replicate. The main factor is the dose of nitrogen fertilization (0, 30, 60, 90 kg N/ha), the second factor is the heigth of the defoliation (5 and 10 cm). Parameters measured were leaf stem ratio, shot root ratio and crude fiber content of alfalfa. The results showed that there was no effect of nitrogen fertilization and defoliation high contrast ratio of leaf to stem, shot root ratio and crude fiber content of alfalfa. Data were analyzed with the results of research based on the F test of variance procedure and Duncan's multiple range test. The results showed that there was no effect of nitrogen fertilization and different defoliation height to leaf stem ratio, shoot root ratio and crude fiber of alfalfa. There are indication that leaf stem ratio and shoot root ratio obtained the best results in the treatment of nitrogen fertilization of 30 kg N/ha and defoliation height of 5 cm.Keywords: alfalfa, nitrogen fertilization, high defoliation, leaf stem ratio, shot root ratio, crude fiberABSTRAKPenelitian bertujuan untuk mengetahui pengaruh pemupukan nitrogen dan tinggi defoliasi yang berbeda terhadap nisbah daun batang, nisbah tajuk akar dan kadar serat kasar pada tanaman alfalfa (Medicago sativa).

Abstract

ABSTRAK Penelitian ini dilakukan untuk mengetahui pengaruh kepadatan dan pola tanam terhadap pertumbuhan, produksi dan kualitas nutrisi orok-orok dan jagung manis yang ditanam secara tumpangsari. Data yang diperoleh dianalisis statistic dengan menggunakan rangcangan factorial 3x2 dengan empat ulangan. Faktor pertama yaitu kepadatan K1, K2, K3 berturut-turut 6, 12, 16 tanaman/m2. Faktor kedua yaitu pola tanam P1 : 1 baris dan P2 : 2 baris. Pelaksanaan penelitian dilakukan selama 3 bulan, bulan kedua dilakukan pengambilan data orok-orok dan bulan ketiga dilakukan pengambilan data jagung manis. Berdasarkan penelitian dapat disimpulkan bahwa pola tanam dua baris dapat menurunkan pertumbuhan, produksi dan kualitas nutrisi tanaman jagung manis, tetapi dapat meningkatkan pertumbuhan, produksi dan kualitas nutrisi tanaman orok-orok kecuali terhadap jumlah daun orok-orok. Kepadatan dari 6 sampai 16 tanaman/m2 menurunkan pertumbuhan, produksi dan kualitas nutrisi tanaman orok-orok maupun jagung manis, tetapi meningkatkan produksi segar tanaman orok-orok.Kata Kunci : Pertumbuhan; Produksi; Nutrien; Orok-orok; Jagung Manis ABSTRACT This study was conducted to find the effect of planting pattern and plant density on the growth, production and quality nutrition Crotalaria juncea L and sweet corn planted in intercropping. The data obtained were statistically analyzed using factorial 3x2 with four replication CRD and tested further if there is a difference between treatments. The first factor of plant density are K1, K2, K3 respectively 6, 12, 16 plants/m2. The second factor is planting pattern P1: single row and P2 : double row. Implementation of the research carried out for 3 months, the second month done data collecting of Crotalaria juncea L and data collecting undertaken three months sweet corn. Based on research it can be concluded that the pattern of planting two rows can be lower growth, production and plant nutrition quality of sweet corn, but it can promote growth, production and quality of crop nutrients Crotalaria juncea L except with respect to the amount of leaves of the Crotalaria juncea L. The density of 6 to 16 plants/m2 lower growth, production and quality of plant nutrients.Key Words : Growth; Production; Nutrient; Crotalaria juncea L.; Sweet Corn
