| This study was designed to evaluate and model the impacts of processing parameters (steaming time, soaking time, paddy moisture content and soaking temperature) on the energy consumption of five rice varieties (NERICA 8, FARO 52, FARO 61, FARO 60 and FARO 44). Energy consumption in the cleaning, soaking, steaming, drying, dehusking, polishing and grading operations were estimated by fitting data on labour, fuel and electricity consumption, time and machine efficiency into standard equations to determine total energy consumption. The energy consumptions were separately modelled using Taguchi and Artificial Neural Network (ANN) techniques for each rice variety. The accuracy of models was determined using the coefficient of determination (R2) and Mean Square... |

| ABSTRACT The upland rice farmers in Suriname use local varieties and low level technologies in the field. As a result, the upland rice grain yield is low, at about 1 000 kg ha-1. Our objective was to evaluate the use of upland rice cultivars from Suriname and Brazil, and the effect of nitrogen, N, phosphorus, P, and potassium, K, fertilizers on cultivation variables. We undertook four field trials in the Victoria Area, in the Brokopondo District, using a randomized block design each with four replications. The most productive rice varieties were BRS Esmeralda (grain yield 2 903 kg ha-1) and BRS Sertaneja (2 802 kg ha-1). The highest grain yield of 2 620 kg ha-1 was achieved with a top dressing application of 76.41 kg N ha-1 20 days after sowing. For P, the... |

| Acylated Steryl Glucosides (ASGs) are unsaponified matters that are ubiquitously distributed in edible plant sources, for example barley, maize and brown rice. ASGs in pre-germinated brown rice have reported to improve insulin activity and blood glucose control mechanisms in the diabetic condition through the activation of insulin like growth factor 1 (IGF-1) and increasing of IGF-1 production. Recently, the medical studies confirm that dietary intake of brown and pre-germinated brown rice is useful for alleviating symptoms of both diabetes and pre-diabetes. To improve the functional dietary intake of Thai rice, identification of ASGs in seven varieties, namely: Khao Dawk Mali 105, PTT1, RD31, Sang Yod, RD6, Niaw Dam Chum Pae and Niaw Dam Maw, brown and... |

| Rice contains several kinds of bio-functional components. In this study, γ-aminobutyric acid (GABA) and Tocopherol, or Vitamin E were identified and their relationships to antioxidant activity using DPPH assay of both brown and pre germinated Thai rice varieties were studied. GABA are one of the two inhibitory neurotransmitters which make the neuron resistant to stimulation by excitatory neurotransmitters and inhibitor of some cancer cells activity whereas Tocopherol, or Vitamin E, which acts as antioxidant and improve blood cholesterol. Identification of GABA and Tocopherol in both brown and pre-germinated brown rice grown from different locations were conducted in eleven varieties, namely: Khao Dawk Mali 105, PTT1, CN1, RD31, Sang yod, RD6, Hom... |

| Research on evaluation of deepwater rice area in Thailand: resent situation and future trend was conducted in 2013. Secondary data collection from the Department of Agricultural Extenion and simple field survey were basic methodology of this research. The objective of the study was to evaluate the deepwater rice area and trend of this production system in Thailand. The research found that in 2012 The deepwater rice covered an area of 388,977 rai (6.25 rai equal to 1 hectare) scatter in 46 provinces. The top five provinces of deepwater rice production area were Prachin Buri, Nakhon Nayok, Pra Nakorn Si Ayutthaya, Chaiyaphum and Nakhon Ratchasima covering and area of 110,509; 60,652; 55,367; 43,175; and 37,057 rai, respectively. The most favorable rice... |
