การจัดเขตศักยภาพการผลิตข้าวจังหวัดประจวบคีรีขันธ์ Thai Agricultural
Satit Tayapat; Saowaluck Arom; Tanadun Chuenmathunpaijit.
Rice production potential zoning of Prachuap Khiri Khan province had been conducted from 2011 to 2013. Research methodology composted of general rice production information collection, soil sampling and crop cutting from farmer field, and field experiment. The research found that there were 4 major rice varieties growing in the area Chainat 1 , Suphanburi 1 , RD31 and Pathum Thani 1. The field experiments for comparing of fertilizer application were conducted 2 seasons at 12 locations. The results showed that L1 area, recommended fertilizer application (T1) gave the average yield of 885 kg/rai, while fertilizer application base on soil analysis (T2) gave the average yield of 785 kg/rai. Farmers’ practice of fertilizer application (T3) gave the average...

การจัดเขตศักยภาพการผลิตข้าวจังหวัดกำแพงเพชรและจังหวัดตาก Thai Agricultural
Kawaporn Phumchaei; Kingkaew Kunket.
Potential Zoning for rice production in the Lower North was carried out in Kamphaeng Phet and Tak Provinces during 2010-2011. The main objective was to create a database for area and appropriate technology for rice production. Procedures started with a survey on soil fertility and rice yield from the areas having soil suitable for rice growing. This was followed by the investigation on appropriate technologies to increase yield potential. Results have shown that the paddy fields in Kamphaeng Phet had an average pH of 5.45, 2.16% organic matter (O.M.), 19.23 ppm Phosphorus (P) and 76.83 ppm Potassium (K), respectively. The major soil texture is Loam having an average rice yield of 560 Kg/rai. Similar procedures were followed for Tak province of which an...

Duangporn Vithoonjit; Kingkaw Kunket; Amornrat Intrman; ChaLermchart Luechaikham.
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. The common varieties which were PTT1 (90.31%), SPR1 (6.22%) and RD31 (0.91%), respectively were planted by direct seeding method with 25-35 kg/rai seed rate,...
