Mulching and synergistic use of organic and chemical fertilizers enhances the yield, nutrient uptake and water use efficiency of sorghum
Integrated nutrient management mulching
2011/1/12
Crop yields in arid lands are generally low and highly variable because of sparse and erratic precipitation leading to water stress. A greenhouse study was conducted to determine the effect of integra...
Community participation is a necessity for project success: A case study of rural water supply project in Jeppes Reefs, South Africa
Community empowerment participation project success water supply
2011/1/11
In South Africa more than 12 million people do not have access to clean water and less than half of the rural population has a safe and accessible water supply. The study attempts to investigate the c...
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...
Wheat Cultivar Differences in Photosynthetic Response to Low Soil Water Potentials:I. Maintenance of photosynthesis and leaf water potential
Drought avoidance Drought resistance Drought tolerance Photosynthesis Triticum aestivum
2009/7/27
Although many studies have shown cultivar differences in photosynthetic response to water deficit, the understanding of detailed mechanisms is not sufficient. We examined the mechanisms of water stres...
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...
Pearl Millet Developed Deep Roots and Changed Water Sources by Competition with Intercropped Cowpea in the Semiarid Environment of Northern Namibia
Heavy water Leaf water potential Rooting pattern Stable isotope Water stress Water uptake
2009/7/24
The practice of intercropping pearl millet with cowpea is widespread among subsistence farmers in northern Namibia. In this region, the scarce and erratic rainfall may enhance competition for the limi...
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...
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...
