| Chainat Province, rice growing areas could be divided by the potential suitability of the soil at 3 levels were very reasonable (soil group 3, 4, 7 and 15) suitable medium (Soil group 6, 17, 18, 21, 22, 24 and 25) and less appropriate. (Soil group 31b, 35b and 55b). Survey and data collection of cultivated rice farmers. Chainat Province Year 2550-2552 included 920 cases showed that rice grown in Chai Nat province has at least nine varieties are consisting PTT 1, CNT 1, PSL 2 ,SPR 1, SPR 3, SPR 60, CNT 80(RD29), PTT 80(RD31) and KDML105 scattered throughout the region. Divided into two groups: rice photoperiod sensitivity (97.93%) were PTT 1, CNT 1, PSL 2, SPR 1, SPR 3, SPR 60, CNT 80(RD29) and PTT80 (RD31). Average yield 774 kg/rai. And rice photoperiod... |

| Paddy soil in Sing Buri province can be classified into 4 levels as high suitability (soil group 3, 4, 7 and 15), moderately suitability (soil group 21), low suitability (soil group 33) and unsuitability (soil group 38). Moreover, yield production potential of those paddy soils can also be divided into 4 levels as more than 850 kg/rai (R1), 701 - 850 kg/rai (R2), 551 - 700 kg/rai (R3) and less than or equal to 550 kg/rai (R4). Field survey of 547 farmers plantation in Sing Buri province during 2007 - 2009 found that at least five rice varieties, which are PTT1, SPR1, RD31, CNT1 and PSL2 were grown.
