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...
Factors Affecting the Night Dark Respiration Rate of Individual Plant in the Later Growth Stage of Rice (Oryza sativa L.)
Carbohydrate Dark respiration Nitrogen Rice plant Ripening Senescence Solar radiation
2009/7/31
Variation of the specific rate of average night dark respiration (Rs-n) expressed as mgCO2 g dry wt. -1h-1 of individual plant was examined in semi-dwarf high-yielding indica, F1 hybrids and japonica ...
Studies on Heading Characteristics of Primary and Secondary Tillers in Rice(Oryza sativa L.) : I. Influence of leaf cutting on heading characteristics of primary and secondary tillers
Delayed heading Heading date Leaf cutting treatment Main stem Panicle initiation
2009/7/31
The purpose of this experiment was to identify the cause of the differences in the heading date and the time of panicle differentiation among individual tillers in a plant. Three varieties, Norin 1, N...
Sterility in Rice (Oryza Sativa L.) Subject to Drought during the Booting Stage Occurs not because of Lack of Assimilate or of Water Deficit in the Shoot but because of Dehydration of the Root Zone
Booting stage Degeneration of spikelet Dehydration Drought Oryza sativa L
2009/7/30
In rice plants a drought at the booting stage is the event most damaging to grain yield because it drastically increases sterility. Our objective was to establish what phosiological processes caused s...
Comparison of Water Use Efficiency of Paddy Rice (Oryza sativa L.) among Locations and Interannual Variation in Humid Areas : 1. Reliability of estimated canopy transpiration rate from meteorological and physiological data of the crop
Canopy resistance Evapotranspiration Leaf area index Penman-Monteith method Rice Stomatal conductance
2009/7/29
The transpiration rate is affected not only by meteorological but also by physiological and structural factors of the crop. Our objectives were to develop a method of estimating the transpiration rate...
Effect of Planting Density on Grain Yield and Water Productivity of Rice (Oryza sativa L.) Grown in Flooded and Non-flooded Fields in Japan
Grain yield Non-flooded paddy field Planting density Rice Water productivity Water-use efficiency Yield components
2009/7/24
The effect of planting density on grain yield and water productivity was evaluated in rice (Oryza sativa L.) grown in non-flooded lowland fields in Japan in comparison with flooded fields. One rice cu...
Concentrations of Kjeldahl-digested Nitrogen, Amylose, and Amino Acids in Milled Grains of Rice (Oryza sativa L.) Cultivated under Organic and Customary Farming Practices
Amino acids Amylose Customary farming practice Kjeldahl-digested nitrogen
2009/7/21
The concentrations of Kjeldahl-digested N were significantly higher in milled rice grains cultivated under customary farming practices than in those grown organically. However, the amylose content sh...
