Get PDFThe change of several soil nutrients in tidal swamp area due to addition of palm oil mill effluent (POME) on soil media. The research objective was to determine the effect of different dosages application of palm oil mill effluent on nutrient changes within planting media. This experiment was conducted in a plastic house by using 8 month ages of plants consisting of 9 pots combined with 6 levels of BOD treatment (Biological Oxygen Demand) concentrations as follows: 20.000 mg/l (L5), 15.000 mg/l (L4), 10.000 mg/l(L3), 5.000 mg/l (L2), 2.500 mg/l (L1) and water only (Lo). The plants were grown for six months from December 2014 to June 2015. The variables observed were pH (H2O), pH KCl, C-Organic, N-Total, P-Bray I (ppm), K- dd, Na, Ca, Mg, Cation Exchange Capacity, Al-dd and H-dd as well as N, P and K nutrients of crop tissues. The results showed that addition of palm oil mill effluent increased soil pH and availability of soil N, P, K, Ca and Mg. Meanwhile nutrients content of N, P and K in tissues were not increased significantly by given POME with BOD up to 20.000 mg/l

Get PDFTITLE : EFFECT OF ARBUSCULAR MYCORRIZHAL FUNGI INOCULATION ON GLOMALIN, GROWTH AND RICE YIELD. The aim of this study was to measure the glomalin production, growth and yield of rice in upland rice fields. The research used Completely Randomized Design with four treatments: two sterilization levels (no sterilisatio and with sterilization) and two levels of mycorrhizae inoculation ( no mycorrhizae and with mycorrhizae). Mycorrhizae (5 g/pot) was inoculated before planting rice seeds. The results showed that Glomalin Total (GT) and Glomalin easily extracted (GEE) were higher in mycorrhizae inoculation, increased by 16% and 20% in non-sterile soil and 25% and 11% in sterile soil compared to non-mycorrhizae inoculation. The content of the GT ranged from 4.95 to 9.74 mg/g soil and GEE 0.99 to 2.78 mg/g soil. Plant height, tillers number and the grain yield was increased by mycorrhizae inoculation significantly. Soil sterilization could reduce the effectiveness of mycorrhizae inoculated.Penelitian pot ini bertujuan untuk mengukur kandungan glomalin, pertumbuhan dan hasil tanaman padi dari inokulalsi mikoriza. Penelitian disusun dengan Rancangan Acak Lengkap dari empat perlakuan yaitu dua taraf sterilisasi (TO, tanpa sterilisasi dan TS, + sterilisasi) dan dua taraf inokulasi mikoriza (M1, - mikoriza dan M1+ mkorisa) dengan enam kali ulangan. Mikoriza sebanyak 5 g/pot diberikan sebelum penamanan benih padi. Hasil penelitian menunjukkan bahwa Glomalin Total (GT) dan Glomalin mudah diekstrak (GEE) lebih tinggi pada inokulasi mikoriza, masing-masing meningkat 16 % dan 20% pada tanah tidak steril (TOM1) dan 25 % dan 11 % pada tanah steril(TSM1) dibandingkan tanpa mikoriza. Kandungan GT berkisar dari 4,95 – 9,74 mg/ g tanah dan GEE 0,99 – 2,78 mg/g tanah. Inokulasi mikoriza meningkatkan C organik tanah, sebesar 13,47 % pada tanah tak steril dan 12,93 % pada tanah steril. Tinggi tanaman, jumlah anakan dan berat gabah kering giling (GKG) nyata dipengaruhi inokulasi mikoriza. GKG pada tanah steril+ mikoriza paling tinggi (20,68 g/pot) namun tidak berbeda nyata dengan tanah tak steril + mikoriza. Sterilisasi tanah nyata tidak mempengaruhi produksi glomalin, pertumbuhan dan hasil tanaman padi

Get PDFTitle : The Effect of Maturity Level of Empty Fruit Bunch Compost and Mulch from Palm Oil Waste to Tomato Productivity in Ultisol. This research was conducted to understand the effect of maturity level of empty fruit bunch compost and mulch from palm oil waste to tomato productivity in ultisol soil. This research used split plot design with mulch as main plot and maturity level of compost as sub plot. The mulch consists of four types: control, shell, fiber, and chopped of empty fruit bunch. The maturity level of compost consists of 5 levels: control, 4 weeks, 6 weeks, 8 weeks, and 10 weeks. Material used in this research was tomato Ratna variety. Compost of 8 weeks gave the lowest value of C/N ratio (35.16) than 4, 6, and 10 weeks. This compost also had the highest level of N-total, P and Mg: 1.34 %, 0.08 %, and 0.25 %. Compost containing the lowest C/N ratio and higher nutrition gave better vegetative growt. Compost of 8 weeks and fiber mulch provided the highest harvest weight and the highest number of fruit (436.56 gram and 16 fruits). Fruit number and fruit weight were lower than general tomato cultivation because of soil condition. Soil type was ultisol which had lower acidity level. The lower KTK level of this soil made distruption in nutrients uptake. Compost of 8 weeks could increase harvest weight 52.59 % higher than control and also could raise number of fruit 82.53 % higher than control. Shell mulch presented negative effect to growth and productivity of tomato.Penelitian ini dilakukan untuk mengetahui pengaruh tingkat kematangan kompos tandan kosong sawit dan penggunaan mulsa limbah padat kelapa sawit terhadap produksi tanaman tomat (Licopersicon esculentum Mill.) pada wilayah dengan tanah ultisol. Percobaan menggunakan rancangan petak terbagi (Split Plot Design) dengan mulsa sebagai petak utama dan kematangan kompos sebagai anak petak. Mulsa terdiri dari empat jenis yaitu tanpa mulsa, cangkang, fiber, dan cacahan TKS. Sedangkan tingkat kematangan kompos terdiri dari 5 taraf yaitu tanpa kompos, kompos 4 minggu, kompos 6 minggu, kompos 8 minggu dan kompos 10 minggu. Bahan yang digunakan adalah tomat (Lycipersicon esculentum Mill.) varietas Ratna. Kompos 8 minggu memberikan nilai C/N ratio terendah dibandingkan umur 4, 6, dan 10 minggu yaitu 35.16. Kompos umur 8 minggu menghasilkan nilai N-total, P, dan Mg tertinggi dibandingkan 3 kompos lainnya yaitu 1.34 %, 0.08 %, dan 0.25 %. Kompos dengan C/N rasio lebih rendah dan kandungan hara yang lebih tinggi memberikan pertumbuhan vegetatif tomat yang lebih baik dibandingkan kompos lainnya. Kompos 8 minggu dan mulsa fiber menghasilkan bobot panen dan jumlah buah terbanyak yaitu 436.56 gram dengan 16 buah. Jumlah dan bobot buah yang dihasilkan pada penelitian ini lebih rendah bila dibandingkan budidaya tomat pada umumnya karena kondisi tanah ultisol yang masam. Nilai KTK yang rendah mengakibatkan terganggunya penyerapan hara tanaman. Bila dibandingkan kontrol, penggunaan kompos 8 minggu meningkatkan bobot buah 52.59 % dan jumlah buah sebesar 82.53 %. Penggunaan mulsa cangkang menunjukan pengaruh negatif terhadap pertumbuhan dan produksi tanaman tomat
