| 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... |

| Crop models are ideally suited to quantify existing climatic risks. However, they require historic climate data as input. While daily temperature and rainfall data are often available, the lack of observed solar radiation (Rs) data severely limits site-specific crop modelling. The objective of this study was to estimate Rs based on air temperature solar radiation models and to quantify the propagation of errors in simulated radiation on several APSIM/ORYZA crop model seasonal outputs, yield, biomass, leaf area (LAI) and total accumulated solar radiation (SRA) during the crop cycle. The accuracy of the 5 models for estimated daily solar radiation was similar, and it was not substantially different among sites. For water limited environments (no irrigation),... |

| 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,... |

| 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... |

| Silk protein solution was sprayed on upland paddy fields of 23 farmers at Phufa Pattana Centre in Nan province to study its potential to increase the yield of rice. Untreated areas were included in each field for comparison. Standard procedures for proper rice growing were applied in all study areas, namely, addition of bio-fertilizer during land preparation and during the cultivation, weed control, etc. Number of tillers, number of plants per tiller, plant height, panicles’ length, number of branches per panicle, number of seeds per tiller, weight of 100 good seeds and grains’ weight per sq.m. were collected. Grain yields per rai were calculated and analyzed statistically between untreated areas and areas treated with silk protein solution. Data were... |

| 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... |
