in order to investigate the relationships of some morphological traits at the early stages of three sugar beet cultivars with final yield at varying levels of water regines, a field experiment was carried out in karaj, and mashhad, in 2001-2003.  the objective of this study was to find the relation of some morphological traits of three sugar beet genotypes (7219-p.69, bp-karaj and 7112)  during...

background and objectives: alkalinity stress caused by the alkaline salts such as na2co3 or nahco3 in the soil. alkaline stress affected germination, growth and crop productivity. moreover, the alkalinity stress can directly damage plant growth, alter the availability of nutrients, and disrupt the balance of ions and mineral nutrition. the application of different seed pretreatment methods is o...

to evaluate the influence of arbuscular mycorrhizal inoculation on growth, yield and minituber production of potato plantlets, a pot experiment was conducted using a factorial based on completely randomized design with four replications. the factors were mycorrizal inoculation (non-inoculated and inoculated with glomus mosseae, glomus etunicatum and mixed of them) and two potato cultivars (agri...

introduction: the exact measurement of the root canal length is of great importance in root canal therapy. although, determination of the root canal length through radiography is the most common method, recently electronic apex locators are being used to determine working length and decrease the number of radiographs. the purpose of this study was to compare the accuracy of an electronic apex l...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

in drought prone environments wheat crop growth and production depends strongly on the water stored in the soil before anthesis and, although some water remains in the soil after harvest, plants experience water deficit. in order to investigate whether water ex-traction patterns, as a plant feature, have a regulating effect on the amount of water used by them at different soil depths, three whe...
