Seed priming, genotype and sowing date effects on emergence, growth and yield of wheat in a tropical low altitude area of Zimbabwe
Seed priming sowing date varieties wheat yield components
2011/1/12
Low wheat yields in low altitude tropical areas result from short winter seasons, late planting and poor stand establishment. Field experiments were carried out over two winter seasons (2005 and 2006)...
Growth and Grain Yield of Wheat in Relation to Differences in Soil Groups : III. Effects of the additional application of nitrogen or phosphoric-acid on the tiller growth and grain yield
Andosol Emergence rate Lodging Red Soil Soil type Spike number Survival rate Varietal difference
2009/8/5
This research was conducted with three varieties (Asakazekomugi, Norin 61 and Norin 64) in Red Soil, Thick High-humic Andosol and Light-colored Andosol. In Red Soil the survival and grain yield of til...
Growth and Grain Yield of Wheat in Relation to Differences in Soil Groups:II. The emergence and survival of tillers and their contribution to yield
Adaptability to low phosphoric-acid concentration Andosol Gary Lowland Soil Number of spikes
2009/8/5
The emergence and survival of tillers and their contribution to yield of three varieties, Asakazekomugi, Norin 61 and Norin 64, were examined in four different soils to find the limiting factors to gr...
Cultivar Differences in Leaf Photosynthesis and Grain Yield of Wheat under Soil Water Deficit Conditions
Cultivar difference Drought Grain yield Photosynthesis Soil water deficit
2009/7/30
Cultivar differences in leaf photosynthesis (LPS) and grain yield of wheat [Triticum aestivum L.] were examined under irrigated and non irrigated conditions in Cerrados, a semi-arid region in Brazil. ...
Effect of Chinese Milk Vetch (Astragalus sinicus L.) as a Cover Crop on Weed Control,Growth and Yield of Wheat under Different Tillage Systems
Chinese milk vetch Minimum tillage No-tillage Weed Control
2009/7/24
Reduced tillage systems are gaining popularity but weed control is often a limiting factor in the adoption of such systems. Cover crops have become a viable option for sustainable agriculture because ...
Growth and Grain Yield of Wheat Experimental Lines with Deep and Shallow Root System in Wet Paddy Fields
Root depth index Root system Waterlogging Wheat Wet endurance Wet injury
2009/7/9
Doubled-haploid lines of wheat with deep and shallow root system, nine lines each, were grown in paddy fields. Grain yield of shallow-rooting 9 lines was higher than that of deep-rooting 9 lines, esp...

Phosphorus Fertilizers Application Methods Yield Wheat Grown Dryland Conditions
2009/1/15
This study was conducted to investigate the efficiency of diammonium phosphate (DAP) and triple superphosphate (TSP) as phosphorus (P) sources and the effect of fertilizer application methods on the ...
Relationship Between Leaf Area Index at Anthesis and Yield in Wheat Under Çukurova Conditions
Leaf Area Index Anthesis Yield Wheat Ç ukurova Conditions
2009/1/14
Wheat yields are closely related to leaf area index (LAI) at anthesis. The optimum leaf area index differs according to genotype and location conditions. Three field experiments were conducted to det...
Influence of pre-sowing magnetic biostimulation on germination and yield of wheat
magnetic field magnetic biostimu- lation magnetic exposure dose germination of wheat yield of wheat
2008/11/14
The effect of pre-sowing magnetic biostimulation of wheat grains on germination and yield is presented. Two magnetic exposure doses were used. The results show that a magnetic field influenced the ger...
