Research ArticleOpen accessPhrase in the titleRice Grain Moisture Determination Using Microstrip Wide-Ring and Microstrip Coupled-Line SensorsHou Kit Mun, Kok Yeow You, Mohamad Ngasri DimonDetermining the Moisture Content (MC) inside rice grain is an important element for grain processesing such as harvesting, storage, quality control and transportation. A microstrip wide-ring sensor and a microstrip coupled-line sensor with low insertion loss were developed to operate at relatively low frequency to determine the MC and relative complex permittivity of rice grain. The complex permittivity for rice … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 3 Apr 2015 · 7,438 accessesView PDFCite
Literature ReviewOpen accessPhrase in the titleMolecular Genetic Basis of Starch Biosynthesis and Waxy Allelic Variation in Rice Grain QualityInnabat Sartbayeva, Aigul Amirova, Dana Mynbaeva et al.The culinary, nutritional, and industrial properties of rice (Oryza sativa L.) grains are fundamentally governed by the structural arrangement of endosperm starch, a complex physiological phenotype shaped by genetic architecture and environmental conditions. This review provides a comprehensive synthesis of the molecular pathways driving starch biosynthesis in rice, centering on allelic diversity within the Waxy (Wx) locus, which codes for … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Sep 2026 · 479 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCompressive Load Resistance Characteristics of Rice GrainSumpun Chaitep, Chaiy Rungsiyakull, Pipatpong WatanawanyooInvestigation was made to observe the compressive load property of rice gain both rough rice and brown grain. Six rice varieties (indica and japonica) were examined with the moisture content at 10-12%. Compressive loads with reference to a principal axis normal to the thickness of the grain were conducted at selected inclined angles of 0°, 15°, 30°, 45°, 60° and … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,179 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFECT OF DROUGHT CONDITION ON GROWTH, YIELD AND GRAIN QUALITY OF UPLAND RICERaumjit Nokkoul, Teerayut WichitparpThus, the objective of this study was to investigate the effect of drought condition on growth, yield and grain quality of two varieties in upland rice: Nangdam and Lebnok. The experiment was performed at the King Mongkut’s Institute of Technology Ladkrabang, Chumphon Campus, Thailand during July to November, 2010. The study was conducted in randomized complete block design with four … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 26 Jul 2014 · 7,269 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Nitrogen Fertilizer on Grain Yield and Fragrant Contents in two Thai Rice VarietiesAyut Kongpun, Chanakan Thebault Prom-u-ThaiNitrogen (N) is commonly applied in rice crop production for improving grain quality and productivity. This experiment aimed to evaluate how applying N fertilizer affects the concentration of 2-Acetyl-1-Pyrroline (2AP), the major fragrant compound in rice grains, between two selected rice varieties with high yield potential and fragrant scent, Pathum Thani 1 (PTT1) and RD22. Rice plants were grown in … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 18 Jul 2021 · 7,458 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResponses of Milling Quality to Nitrogen and Water Management in Modern Long Grain Rice VarietiesThitinan Sreethong, Benjavan Rerkasem, Bernard Dell et al.This study determined how nitrogen (N) fertilizer and water management affect grain yield and milling quality of 9 modern rice varieties with long, slender grain in two field experiments. The effect of N on rice grown in wetland culture was evaluated at 0, 60 and 120 kg N ha-1. In a second experiment the rice in aerobic and wetland culture … …OnLine Journal of Biological Sciences, Vol. 19, Issue 4 · 31 Oct 2019 · 7,224 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResponses of Grain Yield and Nutrient Accumulation to Water and Foliar Fertilizer Management in Upland and Wetland Rice VarietiesNatdanai Juntakad, Sittichai Lordkaew, Sansanee Jamjod, Chanakan Prom-u-thaiThis study evaluated the effects of water and fertilizer managements on grain yield and nutrient accumulation in upland and wetland rice varieties. The two rice varieties representing upland (KH CMU) and wetland (CNT1) ecotypes were grown in different water conditions and fertilizer managements. The interaction between variety and water condition had significantly affected on grain yield and straw dry weight. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 May 2018 · 8,356 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Soil Plant Analysis Development Chlorophyll Meter for Two Growth Stages to Assess Grain Yield of Malaysian Rice (Oryza sativa)Asa Gholizadeh, Mohd Amin Mohd Soom, Anuar Abd. Rahim, Aimrun WayayokProblem Statement: Proper yield management in rice influences grain quality and quantity. Nitrogen site-specific management is also effective on final product of crops because excessive nitrogen application at any growth stage can reduce yield and increase disease incidence. In contrast, suboptimal nitrogen levels at discrete growth stages may substantially reduce plant productivity. The nitrogen status at specific growth stages may … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 11,820 accessesView PDFCite
