Research ArticleOpen accessPhrase in the titleRHEOLOGICAL PROPERTIES OF PADDY SOIL UNDER VARIOUS PRESSURE, WATER CONTENT AND TOOL SHAPESI. A. Mari, C. Ji, F. A. Chandio et al.In this study Burger’s four element model was used to analyze rheological parameter of paddy soil of the Southern China. Two types of tool shape include circular shape (with an area of 12.56 cm2) and rectangular shape (with an area of 12.56 cm2) were use to measure the rheological parameter of paddy soil under different loading pressure (7.65, 10.20 and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 14 Dec 2013 · 7,513 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleRelationship between Rice Yield and Apparent Electrical Conductivity of Paddy SoilsM.H. Ezrin, M.S.M. Amin, A.R. Anuar, W. AimrunProblem statement: Understanding the relationships between rice yield and soil properties such as bulk electrical conductivity is of critical importance in precision farming. The apparent Electrical Conductivity of soil (ECa) is influenced by a combination of physico-chemical properties including soluble salts, clay content and mineralogy, soil water content, bulk density, organic matter and soil temperature. Accordingly, ECa is considered as … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,545 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Leaf Total Nitrogen Content for Nitrogen Management in a Malaysian Paddy Field by Using Soil Plant Analysis Development Chlorophyll MeterA. Gholizadeh, M. S. M. Amin, A. R. Anuar, W. AimrunProblem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 9,238 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPyritization of the Coastal Sediments in the Kelantan Plains in the Malay Peninsula during the HoloceneM.S.K. Enio, J. Shamshuddin, C.I. Fauziah, M.H.A. HusniProblem statement: For a number of geological reasons a proportion of the present coastal plains in the Malay Peninsula were inundated by seawater in the past when pyrite in some of the soils is believed to have been mineralized. Random survey of these sites showed a unique distribution and depth of pyritic layer in the soils along the coastal plains. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 16 Aug 2011 · 8,740 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRoot Elongation, Root Surface Area and Organic Acid by Rice Seedling Under Al3+ and/or H+ StressA. Elisa Azura, J. Shamshuddin, C.I. FauziahProblem statement: Under acidic condition, Al3+ is the most common species in solution. An experiment was conducted to study the effects of Al and/or pH on rice seed germination, root morphology and organic acids release. This study was conducted at ambient temperature in Malaysia. Approach: Two experiments were conducted: (1) Rice seeds undergoing germination were exposed to 0.5 mM CaCl2 … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpatial Variability of Irrigation Water Percolation Rates and Its Relation to Rice ProductivityW. Aimrun, M.S.M. Amin, A. GholizadehProblem statement: Study on spatial variability of vertical saturated hydraulic conductivity or percolation loss was conducted within a plot of an area of 1.2 ha paddy plot to find out the relationship between percolation rate and rice productivity. A paddy soil condition that permits percolation rate of 10-20 mm irrigation water day-1 was recommended in order to get high yield … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis Plant Growth, Yield and Efficiency of Nitrogen Fertilization in Paddy using Green Manure of AzollaSetyono Yudo Tyasmoro, Akbar SaitamaThe development and improvement of cultivation techniques can be done to improve soil fertility; one of the techniques is the application of organic matter. This research intends to study the interaction between Azolla application treatments with different doses of inorganic fertilizers and find out the appropriate dose of Azolla for inorganic fertilizers. This study was conducted in the experimental field … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 9 Feb 2023 · 6,532 accessesView PDFCite
Research ArticleOpen accessIn the abstractRice Yield Related to Fertilizers Applied by Farmers on Two Areas of Marginal Peat Soil in Bengkulu IndonesiaRidha Rizki Novanda, Satria Putra Utama, Andi Ishak, Muhammad Faiz BarchiaThe research was intended to identify amounts of fertilizers applied by small-scale farmers related to rice yield cultivated on marginal peat soils in irrigated paddy fields in Bengkulu. The study was conducted at two peat areas; Pekik Nyaring Village, Air Hitam irrigated rice fields in Central Bengkulu and Sumber Makmur Village, Air Manjuto irrigated areas, Mukomuko Bengkulu Province from June … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 10 Jan 2021 · 7,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractParameter Calibration of Soil in the Poyang Lake Region Based on Discrete Element MethodBaoyu Zhu, Jun’an Liu, Xiongfei Chen et al.In order to obtain the soil parameters of Poyang Lake Region before direct seeding, the soil properties of Duchang County, Poyang County and Xinjian District recollected and the discrete element method model is established. The angle of repose of paddy soil is 53.00° tested by the lateral wall collapse method. Eleven parameters are used to establish EDEM simulation model with … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 16 Dec 2020 · 6,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Composted Animal Manure as Fertilizer on Productivity of Azolla Pinnata Grown in Earthen PondsRistianto Utomo, Cuk Tri Noviandi, Nafiatul Umami, Adhitya PermadiAzolla pinnata contains a high nutritional value with a high protein content of 25%, so it can be used as an alternative to animal feed. The low production of Azolla is caused by the suboptimal use of fertilizers. This study aims were to determine the type of manure (composted manure from poultry, goats, and rabbit) which was the most optimal … …OnLine Journal of Biological Sciences, Vol. 19, Issue 4 · 9 Nov 2019 · 11,061 accessesView PDFCite
