| Survey in paddy field in 2013 amount 54 fields as follow : Mueang Chai Nat 13 fields, Manorom 6 fields, Watsing 5 fields, Sapphaya 7 fields, Sankaburi 9 fields, Hankha district 10 fields, Nakhonsawan 1 field, Uthithani 1 field, Singburi 1 field and Suphanburi province 1 field. We begin survey at 15 days after planting to 90 days and used outbreak data sets by week from Department of Agricultural Extension for decision. The survey results show that brown planthopper high in 2 times per year. The first time is in February to March in Mueang Chai Nat and Hankha district because of brown planthopper outbreak in Suphanburi, migrated to Hankha district and influence of southern wind. The second time is in July to August in Mueang Chai Nat, Hankha and Sankaburi... |

| Measurement of methane emission from major rice production systems is a methodology for data collection of carbon footprint from rice production system. Five major rice production systems were defined for methane emission measurement in 2011 rainy season, including upland rice, rainfed rice, irrigated rice, good agricultural practices (GAP) rice production, and organic rice. Gas samples were taken at one week interval and analyzed by Gas Chromatograph, GC-8A as soon as possible after collection. The research found that upland rice could absorb CH4 at the rate of 90 tons per crop equivalent to 2,258 of CO2. Rainfed rice production system occupied most of rice area in Thailand emitted CH4 at the rate of 58,127 tons per crop equivalent to 1,453,180 tons... |
