Evaluation of Growth-Stage-Specific Crop Coefficients of Maize Using Weighing Lysimeter
crop coefficient evapotranspiration
2015/7/28
Weighing lysimeters are used to measure crop evapotranspiration (ETC) during the growing season. A ratio
of crop evapotranspiration to reference evapotranspiration (ETo) determines a crop coefficien...
Genotypic Variation in Ability to Recover from Weed Competition at Early Vegetative Stage in Upland Rice
Improved cultivar Laos Recover from weed competition Slash-and-burn Traditional cultivar Upland rice
2010/3/4
In northern Laos, weeds are a major constraint to upland rice production in slash-and-burn systems. Two experiments were conducted to assess genotypic variation in ability to recover from weed competi...
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...
Effects of Top Dressing on Growth and Panicle Dry Weight as Affected by Soil Water Stress at the Early Panicle-Development Stage in Rice (Oryza sativa L.)
Leaf area duration Net assimilation rate Rice SPAD Total dry weight
2010/3/4
Rice yield is reduced by a short period of water stress at the early panicle-development stage. This study was conducted to examine the factors that reduce the panicle dry weight of rice subjected to ...
Analysis of Quantitative Trait Loci for Cold Tolerance at the Booting Stage of Rice
QTL interval mapping RFLP graphical genotype
2009/9/10
We analyzed the quantitative trait loci (QTLs) for cold tolerance at the booting stage of a cold-tolerant rice variety, Norin-PL8, which harbors cold tolerance genes derived from a cold-tolerant varie...
Growth Response of Rice (Oryza sativa L.) to Drought:I. Varietal difference in growth rate, nitrogen uptake and tillering habit at vegetative stage
Drought resistance Growth analysis Nitrogen uptake Plant type Rice Tillering habit
2009/8/6
Varietal differences in growth response to drought were studied in order to determine major attributes composing drought resistance in the rice plant. Eight rice varieties of different hydrological b...
Physico-ecological Studies on Quality Formation of Rice Kernel : III. Effects of ripening stage and some ripening conditions on free amino acids in milled rice kernel and in the exterior of cooked rice
Cooked rice Eating quality Free amino acids Milled rice
2009/8/6
Free amino acids (FAA) in the cooked rice exterior and in milled rice kernels (ground milled rice) were studied from the standpoint of taste. The amount and proportion of FAA in the exterior of cooked...
