Methodologies for Root Drought Studies in Rice H.E. Shashidhar Amelia Henry Bill Hardy
2013/11/20
Root biology is at the forefront of progressing fields to improve agricultural productivity in low-input systems. Although there is a strong case for the role of roots in plant performance under droug...
Using precipitation effectiveness variables in indexing drought in semi-arid regions
Drought indexing precipitation effectiveness variables semi arid regions
2011/1/12
This study proposes a new drought index based on several precipitation-based parameters to quantify drought hazard in semi arid region. In addition to the practice of using only rainfall volume for in...
Effects of Pre-Flowering Soil Moisture Deficits on Dry Matter Production and Ecophysiological Characteristics in Soybean Plants under Drought Conditions during Grain Filling
Dry matter production Photosynthesis Root system development Senescence
2009/7/31
Summer crop plants grown in rain-fed fields suffer from drought during a hot and relatively dry summer after the rainy season called "Baiu" in Japan. Since crop plants might develop vigorous shoots wi...
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...
Productivity and Water Source of Intercropped Wheat and Rice in a Direct-sown Sequential Cropping System:The Effects of No-tillage and Drought
Competition Crop rotation Deuterium Direct sowing Hydrogen stable isotope Intercropping No-tillage, Water use
2009/7/24
In Japan, wheat-rice crop rotation with the practice of rice transplanting has been quite popular in the past. Mechanized direct-planted wheat-rice sequential cropping was developed at the Aichi Prefe...
Water Competition of Intercropped Pearl Millet with Cowpea under Drought and Soil Compaction Stresses
Deuterium Heavy water Leaf water potential Mechanical stress Stable isotope Water source Water uptake
2009/7/24
Intercropping pearl millet with cowpea is a common practice in semiarid areas. Under limited water environments, competition for soil water between intercropped plants may be strong. Furthermore, the...
Effect of Nontilled Cropping on Drought Injury of Upland Rice
Drought injury Nontilled cropping Upland rice
2009/7/15
The effect of non tillage on drought injury of upland rice was studied in Andosol upland fields. In 1988, 1990, and 1992, upland rice (cv. Toyohatamochi) was grown on nontilled and tillaged upland fi...
