| New crop varieties often have been promoted in developing countries based upon superior yield vis-a-vis locally available varieties. This research presents a hedonic model for upland rice by drawing upon the input characteristics and consumer good characteristics model literature. Model specification tests determine that a combination of production and consumption characteristics best explains the willingness to pay for new upland rice varieties. This non-separable household model specification determined that four traits explain the willingness to pay for new rice varieties: plant cycle length, plant height, grain elongation/swelling and tenderness. Yield was not significant explanatory variable for the willingness to pay for seed. The implications... |

| Survey and classification of highland rice cultivation areas to indicate acid soil crisis was conducted on altitude 700 meters above sea level. Soil sampling was conducted form 7 districts of Mae Hong Son province are namely Muang, Khun Yuam, Mae La Noi, Mae Sariang, Sop Muey, Pai and Pang Ma Pha in the year 2012-2013. A total of 115 soil samples were consisting of 68 paddies and 47 upland conditions. Soil samples were analysis to find out the soil pH. The result showed that the strongly acid, moderately acid and slightly acid are 39.13, 21.74 and 20.86 percentages, respectively. In other hand, the natural, very strongly acid and extremely acid are 8.7, 7.83 and 1.7 percentages, respectively. However 39 percent of upland soil sample and 38 percent of paddy... |

| This research aimed to access farmer participatory breeding in selecting the local upland rice varieties for desirable agronomic traits, good cooking and eating grain characteristics. The research carried out in the land reform area of amphoes Mueang, Lamae, Thung Tako in Chumphon province. The experiment comprised 12 upland rice varieties, 11 experimental lines and 1 standard check, by using the Randomized Complete Block design with 4 replications. Results indicated that farmers had selected Samdeaun, Phukhaotong, Nahngkruan, Lebnok and Dawkkham varieties for desirable agronomic traits with reasonable uniform panicle, good tillering ability, long panicle, many secondary branches, large and heavy grains. For cooking and eating qualities, they selected... |

| The development of agricultural system paddy rice terrace one is an activity under the project contrary to the security area, Phukhat Phumiang Phusoidao as a Royal projects. To the people Ban Nam khap - Nam juang Tambon Bo Phak, Amphoe Chat Trakan, Phitsanulok Province. 2011 Crop season, farmers participating in the project include 46 cases converting upland field to area is paddy rice terrace was 192.2 rai. The test varieties / lines of rice that have the potential for the area. Rice promising line PSL95120-28-5-R-R has average highest yield at 801 kg per rai. While Bue Po Lo Mae Nah Chang Nuea, RD39, Khao Hom, La-oop and Khao Luang San Patong varieties average yield did not differ significantly at 604, 602, 594, 591 and 515 kg per rai, respectively,... |

| Development of local rice variety at Krabi Rice Research Center is an experiment under local upland rice breeding program in the southern region for compensating rubber trees and oil palms. One hundred and twenty rice varieties that farmers grow in the southern region were selected to study since 2008 until now. The aims of this study are to record the characteristics, categorize, investigate, select pure rice seed, compare production and test on using nitrogen fertilizer. The result showed that this variety, Dokkha, is photoperiod sensitive. It has 332 kg per rai, straight clum 150 cm plant height and 145 - 150 days maturity, green leaves, 8 seeds per panicle, straw colored husk, 20.74 % amylose content and susceptible to rice blast disease. For... |

| Converting Upland Rice Fields to Rice Terraces in Slopping Area is one of the chosen rice planting system for sustainable rice cultivation on the mountainous area in the upper northern of Thailand. It can increase more double yield than from the upland rice . Water preserving and soil fertility problems are always found in Converting Upland Rice Fields to Rice Terraces in Slopping Area. Studying water and rice nutrient management in Samoeng Rice Research Center was founded that the yield from 5 water regime treatments were not significantly. For rice nutrient management, the yield from adding phosphorus combination with potassium chemical fertilizer was not significantly with adding nitrogen combination phosphorus and potassium chemical fertilizer. But the... |
