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...
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...
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...
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...
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 ...
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 ...
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 ...
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 ...
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...
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-...
Dry matter production and nitrogen absorption of Crotalaria juncea and Sesbania cannabina grown under different underground water levels(16cm[high]and 32cm[low]below the ground)were evaluated in exper...
High-yielding rice varieties require a large accumulation of N in panicles. The objectives of this study were to clarify the change in N allocation during the ripening period (Exp. 1) and to quantify ...
Three types or eddoe plants(Colocasia esculenta(L.) Schott), i.c., daughter-tuber type(cv. Uhan and Ishikawawase), mother-and daughter-tuber type(cv. Akame), and mother-tuber type(cv. Taiwan-imo), we ...
To analyze the cultivar differences of nitrogen fixation capacity in soybean under a high soil nitrogen condition, we estimated the amount of nitrogen fixed during the growing season and the percenta...
The researches were made during 1992-2001. There were collected 10704 specimens of carabidaes (Coleoptera-Carabidae). The species with the largest number of collected specimens were: Pseudophonus rufi...
