High-yielding Crop Management by Enhancing Growth in Reproductive Stage of Direct-Seeded Rainfed Lowland Rice (Oryza sativa L.) in Northeast Thailand
Biomass production Growth duration Nitrogen uptake Reproductive stage
2010/3/4
The crop management in direct-seeded rice to promote growth during the reproductive stage was evaluated in weed-controlled toposequentially intermediate fields in a small watershed in Northeast Thaila...
Effect of Plot Size on Accuracy of Yield Estimation of Rainfed Lowland Rice Genotypes with Different Plant Heights and Grown under Different Soil Fertility Conditions
Competition Plant height Plot size Rice genotypes Selection trial Yield estimation
2009/7/29
Breeding programs for rainfed lowland rice normally use large plot sizes for accurate estimation of yield. Resource requirements are reduced and more genotypes can be tested if a small plot size can b...
Genotypic Variation in Response of Rainfed Lowland Rice to Prolonged Drought and Rewatering
Drought Drought recovery Osmotic adjustment Rainfed lowland rice Root
2009/7/29
Duration of the drought period is important for plant response during drought and after rewatering. We hypothesized that, if drought duration is extended, (1) high seedling vigor and rapid developmen...

Estimating Percolation and Lateral Water Flow on Sloping Land in Rainfed Lowland Rice Ecosystem
Percolation Rice Toposequence Water table
2009/7/24
Quantifying water losses in paddy fields assists estimation of water availability in rainfed lowland rice ecosystem. Little information is available on water balance in different toposequence position...
Molecular Breeding for Rainfed Lowland Rice in the Mekong Region
Grain quality Marker-assisted selection Molecular breeding Rice
2009/7/24
In the past 20 years, the rice-breeding program in Thailand had little success in developing new cultivars to replace Kao Dawk Mali 105 (KDML105) and Kao Khor 6 (RD6) for the rainfed lowland rice envi...
Effects of Soil Clay Content on Water Balance and Productivity in Rainfed Lowland Rice Ecosystem in Northeast Thailand
Oryza sativa Paddy Percolation Seepage Water table
2009/7/23
Water availability is one of the determinants of productivity of rainfed lowland rice (Oryza sativa L.). Quantifying water losses from a paddy field, such as deep percolation and lateral seepage, assi...
Relay-Intercropping of Stylosanthes guianensis in Rainfed Lowland Rice Ecosystem in Northeast Thailand
Dry season Forage production Green manure Nutrient deficit Rainfed rice
2009/7/23
We evaluated the usefulness of the Stylosanthes guianensis (stylo)- rice relay-intercropping system for increasing agricultural productivity in Northeast Thailand. Although large production variabilit...
Stomatal Responses in Rainfed Lowland Rice to Partial Soil Drying;Evidence for Root Signals
Drought Rainfed lowland Rice Root signals Stomatal conductance Water deficit
2009/7/21
The role of root signals in water deficit responses of rice (Oryza sativa L.) is important in the alternate flooding and drying conditions encountered in the rainfed lowlands, where the abundant roots...
Nutrient Deficiency in the Rice-Stylo (Stylosanthes guianensis) Relay-Intercropping System in Rainfed Lowland Rice Ecosystem in Northeast Thailand
Dry season Restoration trial Successive cropping Sulfur deficiency
2009/7/21
The rice-stylo (Stylosanthes guianensis) relay-intercropping system in paddy fields has previously been shown to increase agricultural productivity in Northeast Thailand, but successive relay-intercro...
Stomatal Responses in Rainfed Lowland Rice to Partial Soil Drying;Comparison of Two Lines
Hardpan Leaf water potential Mechanical impedance Rainfed lowland Rice Root signals Stomatal conductance Water deficit
2009/7/20
Previously, we demonstrated that root tips in drying soil communicate with shoots for stomatal closure in rainfed lowland rice, despite further water being available at depth. This study examines vari...
