Abstract

Nutrient Uptake and Efficiency Fertilizing to Growth Variety Local of RiceAbstract: The study was aimed to determine effects of phosphate fertilizer dosage and varieties on growth, nutrient uptake and fertilizing efficiency of landrace paddy. The research was conducted in Village Aneuk Glee, Indrapuri Sub District, Aceh Besar District. Analysis of phosphorus uptake of rice plants was performed at Laboratory of Soil Research Institute, Bogor. Experiment was arranged in a split plot design with three replications. Factor of phosphorus fertilizer dosage, consisting of three levels (0 kg/ha, 50 kg/ha and 100 kg/ha) was set as main plot and variety (50 varieties) as subplot. Variables observed were plant height, number of tillers, wet weight biomass, dry weight biomass and fertilizing efficiency. Results showed that phosphorus fertilizer dosage exerted highly significant effects on plant height, number of tillers at 20, 23 and 26 days after transplanting, dry weight biomass, nutrient uptake and fertilizing efficiency and exerted significant effects on number of tillers at 14 days after transplanting and wet weight biomass. Variety exerted highly significant effects on plant height, number of tillers, wet weight biomass and dry weight biomass. There were no significant interactions between phosphorus fertilizer dosage and variety on all the observed variables.Abstrak: Penelitian ini dilaksanakan untuk mengetahui pengaruh dosis pupuk fosfat dan varietas terhadap pertumbuhan, serapan hara dan efisiensi pemupukan tanaman padi lokal.

The Influence of Phosphat and Sulfur Fertilization on Growth and Nutrient Absorption and Rice Field Yield Efficiency of Paddy (Oryza sativa L.)Abstract. This research was conducted in the Uleepulo Village, Dewantara Sub District, Aceh Utara District. This study was aimed to investigate effects of phosphorus and sulfur fertilizers and their interactions on nutrient uptake and growth and yield efficiency of paddy. Experiment was arranged in a factorial randomized complete block design 4 x 4 with 3 replications. Phosphorus fertilization consisted of 4 levels: 0, 50, 100, 150 kg ha-1. Sulfur fertilization consisted of 4 levels: 0, 40, 80, 120 kg ha-1. The results showed that phosphorus and sulfur fertilizers significantly affected paddy height at 30 and 45 day after planting, tiller numbers and productive tiller numbers. Phosphorus and sulfur fertilizers significant affected panicle length and grain numbers per panicle. Phosphorus and sulfur fertilizers did not significantly affect the number of empty grains, 1000 grain weight and yield. Phosphorus fertilizer did not significantly affect phosphorus uptake and also sulfur fertilizer did not affect sulfur uptake. However, there was an interaction between phosphorus and sulfur fertilization on phosphorus uptake. Sulfur fertilizer significantly affected phosphorus uptake. There was no interaction between phosphorus and sulfur fertilization on sulfur uptake. Phosphorus fertilization significantly affected yield efficiency, while sulfur fertilization did not significantly affect the yield efficiency. Additionally, there was no significant interaction between phosphorus and sulfur fertilization on yield efficiency of paddy.Abstrak.

This research was conducted by using randomized block design (RBD) factorial pattern which consists in two factors with three replications. The first factor is KCl fertilizer residues which consist: 0, 100 and 150 kg ha-1, the second factor is the residue of rice straw compost which consists of: 0, 10 and 20 ton ha-1. This research was conducted in Empetring Sub-district, Darul Kamal, Aceh Besar District. Further soil analysis was performed at the Soil Chemistry Laboratory, Agriculture Faculty, Syiah Kuala University, Banda Aceh. The results of research showed that KCl fertilizer residues provide a significant influence on the pH, available-P, exchangeable-K, organic-C, total-N, cation exchange capacity, but not significant effect on plant height that aged of 15, 30 and 45 Days after planting and number of seedlings aged 15, 30 and 45 days after planting. The provision of rice straw compost residual treatment gives a very significant influence on the pH, available-P, exchangeable-K, organic-C, total-N, cation exchange capacity and the real for the plant height that age 30 Days After Planting, but not significant effect on the exchange-K, plant height age of 15 and 45 days after planting and the number of seedlings age of 15, 30 and 45 days after planting. There is a very real interaction to the pH and the organic-C, but not significant effect on the pH to available-P, exchangeable-K, total-N, cation exchange capacity, plant height that age 15, 30 and 45 days after planting and seedlings that age 15, 30 and 45 days after planting.Abstrak: Penelitian ini bertujuan untuk mengkaji pengaruh residu pupuk KCl dan residu kompos jerami padi musim tanam rendengan terhadap sifat kimia tanah dan pertumbuhan tanaman padi sawah musim tanam gadu.

Abstract: This research was aimed to determine the potential carbon stored on mangrove and fishpond areas in the coastal zones of Banda Aceh. In this study the allometric method was used for the measurement of biomass. The biomass estimation was done on the stems and roots of mangrove by measuring the trunk diameter at the breast height. The size of plots 10 m x10 m for the observation of trees, 5m x 5m for observation of sapling and 2 m x 2m for observation of seedling of mangrove.Each type of mangrove was recorded of location names and the scientific names. The analysis of soil carbon was done by taking a composite soil samples at three depth levels: 0-15 cm, 15-30cm, and 30-50 cm. The results showed that there are six mangrove species was found in the study areas: R. apiculata, R. mucronata, R. stylosa, A. alba, A.lanata, andS. alba.The species of mangrove that have awide spread in the coastal zones of Banda Aceh is R.mucronata, with the number density of 224stems/ha.The potential carbon stored in soil, mangrove stem, fishpond, and roots are 55.31ton C / ha, 16.50ton C / ha, 10.51 ton C / ha, and 6.92 ton C / ha respectively. Total carbon stored in mangrove and fishpond areas in the coastal of Banda Aceh was 89.24 ton C / ha. Abstrak: Penelitian ini bertujuan untuk menghitung potensi karbon pada lahan mangrove dan tambak di kawasan pesisir Kota Banda Aceh. Pengukuran biomassa menggunakan metode alometrik yang dilakukan pada batang dan akar mangrove dengan cara mengukur diameter batang setinggi dada pada plot contoh persegi panjang yang dipilih secara acak.

Interaksi takaran pemberian cacing tanah pada berbagai jenis bahan organik berpengaruh sangat nyata terhadap jumlah polong berisi, berat biji per plot, dan berpengaruh nyata terhadap tinggi tanaman 15 HST, jumlah cabang produktif, jumlah polong hampa, dan berat 100 biji, akan tetapi tidak berpengaruh nyata terhadap tinggi tanaman 30 dan 45 HST. Nilai terbaik berat biji per plot kedelai dijumpai pada takaran cacing tanah 27,65 g per plot pada jenis bahan organik jerami padi.Soil Physical Properties and Yield of Soybean (Glycine max L) in Compacted Soil Due to Provision of Earthworm and Organic MatterAbstract. This study was aimed at assessment of changes in soil chemical and physical properties, as well as growth and yield of soybean due to provision of earthworm and organic matter on compacted soil. The experiment used a randomized complete block design, consisting of two factors, i.e. dosage of earthworm and type of organic matter.  Variables observed included three aspects: (1) Soil physical properties, (2) soil chemical properties, and (3) growth and yield of soybean. The results showed that  interactions between dosage of earthworms and type of organic matter were highly significant on soil permeability, soil aggregate stability index, and only significant on soil volume weight, total soil porosity and soil water content at pF 2.54 , but not significant on soil water content at pF 4.2. Similarly, interactions between dosage of earthworm and type of organic matter were also highly significant on soil pH H2O, P-available, and just significant on soil pH KCl, C organic, total N, Ca-exchangeable, and not significant on K- exchangeable, Mg-exchangeable, and soil CEC.  The best value of changes in soil physical and chemical properties was found at dosage of 20 g earthworm per plot in a type of organic rice straw.  Interactions between dosage of earthworm and type of organic matter were highly significant on number of pods, seed weight per plot, and just significant on plant height 15 day after planting (DAP), number of productive branches, number of empty pods, and 100 seed weight, but not significant on plant height of 30 and 45 DAP.   The best weight of soybean seeds per plot was found at dosage of earthworms 27.65 g per plot and a type of organic rice straw.
