Evaluation Of Biological And Chemical Seed Treatments For Management Of Rice Diseases, Sherif Adam Sharfadine

Graduate Theses and Dissertations

Rice is the primary staple for more than half of the global population and is the second most important cereal worldwide. In the US, rice is primarily grown in the southern states, with Arkansas leading production and responsible for 47% of the total rice production in the country. Diseases cause significant yield losses in rice. Sheath blight, rice blast and bacterial panicle blight are the main diseases in rice and cause significant yield losses. Sheath blight alone could cause up 50% yield loss in heavily damaged fields with highly susceptible cultivars. Additionally, rice seed and seedling diseases primarily caused by …

B.R. Wells Arkansas Rice Research Studies 2021, J. Hardke, X. Sha, N. Bateman

Arkansas Agricultural Experiment Station Research Series

Arkansas is the leading rice producer in the United States. The state represents 47.5% of total U.S. rice production and 47.8% of the total acres planted to rice in 2021. Rice cultural practices vary across the state and across the U.S. However, these practices are also dynamic and continue to evolve in response to changing political, environmental, and economic times. This survey was initiated in 2002 to monitor and record changes in the way Arkansas rice producers approach their livelihood. The survey was conducted by polling county extension agents in each of the counties in Arkansas that produce rice. Questions …

Mineral Element Discrimination Of Selenium-Enriched Rice In Ningxia And Its Quality Evaluation, Yang Xiao-Chen

Food and Machinery

Objective:The element content and physical and chemical quality were analyzed from the nutritional quality of Selenium (Se)-enriched rice in Ningxia.Methods:25 rice samples from different brands in Ningxia were selected as the research object, and 26 mineral elements in which were determined by inductively coupled plasma mass spectrometry (ICP-MS), and multivariate statistical analysis of these elements was conducted.Results:Through the analysis of the difference of element content between Se-enriched rice and ordinary rice, the quality of Se-enriched rice was distinguished. Moreover, it was found that Se-enriched rice was rich in four kinds of elements such as Ca, …

Quality Properties Of Mixture Of The Proso Millet And Rice, Ren Jing, Jiang Wen-Qian, Zhao Ning, Ji Xiao-Hui, Li Meng-Qing, Du Shuang-Kui

Food and Machinery

Objective:The purpose of this study was to mix rice and proso millets and obtain high nutritional value, fantastic taste and flavor mixed rice.Methods:By adding different proportions of proso millets to rice, the nutritional value and fantastic taste of mixed rice were evaluated via the amino acid score (AAS), texture profile properties, sensory evaluations and flavor properties.Results:There were significant differences in the texture profile properties, sensory evaluations and flavor properties among cooked proso millets additions. The proportion of the cooked rice addition was significantly positively correlated to the gumminess and chewiness of rice, while it was …

Research On Rapid Prediction Model Of Rice Moisture Content Based On Near Infrared Spectroscopy, Lu Du, Tang Jian-Bo, Jiang Tai-Ling, Chen Zhong-Ai, Pan Mu

Food and Machinery

Objective:In order to established a non-destructive, rapid and efficient method for detecting the moisture content of rice. Methods:This study, 161 rice samples were collected from 5 different regions were studied by near infrared spectroscopy combined with stoichiometry. By eliminating abnormal spectra and preprocessing the spectra, the prediction model of rice moisture content was established by partial least squares regression. Results:15 abnormal spectrum samples were eliminated using the method of principal component analysis combined with mahalanobis distance. The best spectral pretreatment was to eliminate the constant offset. The prediction model R2CAL established in the training set was 0.994 …

International Rice Outlook: International Rice Baseline Projections 2021–2031, A. Durand-Morat, S. Bairagi

Research Reports and Research Bulletins

The war in Ukraine and the lingering effects of the COVID-19 pandemic are pushing input costs to record levels. Although rice prices have increased some in the last several months, production costs have increased more than proportionally, undermining rice profitability.

We project global rice production will surpass global rice consumption for most of the coming decade, with a small deficit developing by the end of the projected period.

The projected growth in production is almost exclusively due to productivity gains since the global rice area is projected to increase only marginally by 2029–2031.

The projected growth in global rice consumption …

High Resistant Starch Rice: Variation In Starch Related Snps, And Functional, And Sensory Properties, Ming Hsuan Chen, Karen Bett-Garber, Jeanne Lea, Anna Mcclung, Christine Bergman

Hospitality Faculty Research

Human diets containing greater resistant starch (RS) are associated with superior glycemic control. Although high amylose rice has higher RS (29 g/kg to 44 g/kg) than lower amylose content varieties, sensory and processing properties associated with RS have not been evaluated. This study used variants of Waxy and starch synthase II a (SSIIa) genes to divide high amylose (256 g/kg to 284 g/kg) varieties into three haplotypes to examine their effects on RS, RVA parameters, and 14 cooked rice texture properties. RVA characteristics were influenced by both genes with peak and hotpaste viscosity differentiating the three haplotypes. Setback from hotpaste …

Addressing Rice Waste In University Cafeterias Using Material Flow Analysis And System Dynamics Modeling, Abigail Marie T. Favis, Charlotte Kendra Z. Gotangco-Gonzales, Ana Erika Lareza

Environmental Science Faculty Publications

Food waste has emerged as one of the focus areas in sustainability research. At the Ateneo de Manila University, previous studies have found that food waste is composed mainly of rice. This study, therefore, analyzed cafeteria rice systems in the university through a material flow analysis (MFA) to identify key factors for formulating effective rice waste reduction techniques and then applied the results toward developing system dynamics (SD) models as tools for decision-making. The MFA found that the total mass of produced known rice waste was 49.48 kg/d. The largest sources of rice wastes were the upstream processes of the …
