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... |

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... |
