Abstract: Aerobic rice is the rice production technology without standing water in the field but having some irrigation, using rice lines are varieties that showed good response to input factors and good adaptation in aerobic condition. This research project was the collaboration between IRRI and Bureau of Rice Research and Development under rainfed lowland rice project in northeast project during 2005 -2008. The objective of this study was to investigate the rice production of aerobic rice and varietal evaluation for rainfed rice in upland condition. They were 5 groups of rice lines (total 150 lines) from aerobic, irrigated, drought tolerant, rainfed lowland rice from IRRI and northeastern part of Thailand to evaluate their response subjected to different conditions eg rainfed upland, irrigation, drought during seedling and drought during flowering stage. The results showed that aerobic rice group gave higher yield potential than those under irrigated, rainfed and drought conditions. The aerobic rice production technology is to grow rice by drilling with spacing between rows 40 cm comparing to the farmer's practice by broadcasting dry seeds in the field. The research conducted in the farmer's field at Amphur Pimai, Nakornratchasima province and Amphur Pochai, Roi-et province in rainfed condition and Amphur Kosum, Mahasarakam province in upland condition. The results indicated that aerobic rice production technology gave higher grain yield than the farmer's practice due to better uniform of seed germination and plant growth and including convenient practice in weed control between the rice rows. The outcome from the field-day activity at Amphur Kosum, Mahasarakam province, showed that the farmers were interested in aerobic rice production technology and expected to get more yield but they had to spend more during growing stage and weeding practice. For the sake of time saving and reduce work force used in weed control, the adapted plough was attached to hand tractor for dragging between rows. After 3 years of research, it was found that aerobic rice lines gave high yield but it needed further investigation on adaptability rice.
