The market success of any rice cultivar is exceedingly dependent on its grain appearance, as well as its grain yield, which define its demand by consumers as well as growers. The present study was und...
Contribution of savings and credit cooperatives to food crop production in Swaziland: A case study of smallholder farmers
Smallholder farmers savings and credit cooperatives contribution food crop production
2011/1/13
Using primary data collected in Ludzeludze and Bhekinkhosi/Mliba RDAs from 80 smallholder farmers in the 2008 cropping season, the study used a Cobb-Douglas production function model to analyze the co...
Adaptive Regulation of Photosynthesis in Rice Plant to Weak Light Condition and the Contribution of Root Activity to Regulation Mechanism
Dark respiration Dry matter production Nitrogen absorption Photosynthesis Rice plant Root respiration
2009/8/6
Three cultivars of rice plants were grown in pots in a shading frame of 50% light intensity and on shadowed place at high altitude of 303m in hillside during the different period from tillering to ear...
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...
Groundnut Ideotype:Its Agro-physiological Characteristics and Contribution of Subsp fastigiata
Arachis hypogaea L Dry matter partitioning ratio Harvest index Ideotype Inter-subspecific hybrid cultivar
2009/8/4
In groundnut (Arachis hypogaea L.), it is presumed that stem-system has no substantial mechanical role in supporting the pods. In order to assess whether a reduced partitioning of dry matter to stems ...
Contribution of Sink and Source Sizes to Yield Variation among Rice Cultivars
Dry matter production Nitrogen application Non-structural carbohydrate Sink Source and Yield
2009/7/29
In order to identify the key factors that arrest yield improvement in rice, we observed fifteen divergent cultivars in a field at Kyoto, Japan in 1995 and 2001 under various nitrogen (N) regimes. The ...
Contribution of Biomass Partitioning and Translocation to Grain Yield under Sub-Optimum Growing Conditions in Irrigated Rice
Biomass production Grain yield Harvest index Rice Translocation
2009/7/29
The International Rice Research Institute (IRRI) has developed a new plant type (NPT) and F1 hybrids to further increase rice yield potential. In this study we compared yield and yield-related traits ...
Acetylcholine as a Signaling System to Environmental Stimuli in Plants:I. Contribution of Ca2+ in heat-stressed Zea mays seedlings
AChE activity ACh response Ca2+ Heat stress Ion channels Zea mays
2009/7/27
Plant growth is influenced by transport of water, ions and hormones under various environmental stresses. If acetylcholine (ACh) mediates the opening and/or closing of ion channels in plants just as ...
Relative Contribution of Hetero- and Auto-trophic Growth to Genotypic Variation of Seedling Vigor in Rice (Oryza sativa L.)
Autotrophic growth Genotypic variation Heterotrophic growth Oryza sativa L.,Relative growth rate Seed reserve Seedling vigor
2009/7/24
To elucidate the major physiological process to cause genotypic variation in the seedling vigor of rice, we analyzed the dry matter accumulation in the seedling for diverse cultivars distinguishing he...
Difference in δ15N Signatures among Plant Parts of Perennial Species Subjected to Drought Stress with Special Reference to the Contribution of Symbiotic N2-fixation to Plant N
Actinorhizal plant δ15N 15N natural abundance method Nitrogen fixation Perennial plant
2009/7/24
The 15N natural abundance method has been widely used for evaluation of symbiotic N2-fixation. The method inevitably requires a reference plant that reflects soil derived δ15N similar to that in a N2-...
Growth of Crotalaria juncea and Sesbania cannabina Under Different Underground Water Levels and Their Nitrogen Contribution to the Succeeding Spinach Plant
