introduction lentil (lens culinaris medik.) is a good source of protein, carbohydrates as well as minerals, vitamins and unsaturated fatty acids as such it plays an important role in the human diet and cultivated worldwide. water shortage is one of the most important abiotic factors that can limit morphological, physiological, yield, and plant distribution. legumes such as lentil are highly sen...

constant rate of strain (crs) consolidation is a rapid test method used for determination of compressibility of clayey soils. in a crs test, the appropriate strain rate is selected based on pore water pressure ratio, i.e. the ratio of pore pressure to total stress. in the present study, to investigate the effect of strain rate on variation of relative pore water pressure, four different clay sa...

abstract this study was conducted at rudasht research farm in isfahan to evaluate tolerance to zinc (zn) deficiency of 30 spring wheat genotypes, using split plots in a randomized complete blocks design with triplications. main plot consisted of two zn levels (zero and 80 kg zn ha-1 applied as zinc sulfate at planting). the results of anova as well as correlations between tolerance and suscepti...

to study the phenotypic and genotypic diversity of some important agronomic traits associated with yield in white beans, 30 genotypes of white bean were evaluated using a randomized complete block design with four replications in two environments under water stress and non stress conditions. analysis of variance for most of the traits showed significant differences among genotypes, indicating t...

dieback of trees is a serious problem in many different regions of the world and city authorities are concern about conserving and maintaining the green spaces in the big cites. this study was conducted to evaluate the early dieback and yellowing of sycamore trees (platanus sp.) by using a completely randomized block design (split split plot) in 15 replications (sites) in 2009. the main plot wa...

Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

the response of root to water stress is one of the most important parameters for researchers. study of growth and distribution of root under different irrigation managements helpsresearchersto a better understanding of soil water content, and the availability of water and nutrition in water stress condition. to investigate the effects of four levels of irrigation under two different deficit irr...
