The model in this research was created based on the Artificial Neural Network (ANN) and calibrated in the Sefid-rood dam basin (excluding Khazar zone). This research was done by gathering and selecting peak flows of hydrographs from 12 sub basins, the concentration time of which was equal to or less than 24 hours and was caused only by rainfall. From all the selected sub basins, totally 661 hyd...

به منظور بررسی اثرات تاریخ کاشت و سطوح تک‌آبیاری بر عملکرد ارقام مختلف گندم دیم، تحقیقی بر پایه طرح بلوک‌های کامل تصادفی و به صورت اسپلیت اسپلیت پلات در سه تکرار و به مدت دو سال زراعی (83–1381) در ایستگاه تحقیقات کشاورزی دیم، مراغه به اجراء در‌آمد. سه تاریخ کاشت (کرت اصلی) شامل: اوایل مهر، اواسط مهر و اواخر مهر، سه میزان تک‌آبیاری (کرت فرعی) شامل: بدون آبیاری (شرایط دیم)، تک‌آبیاری به میزان 50 ...

The positive and beneficial effects of mycorrhizal symbiosis on the growth of various plants have already been documented. Most arable crops can mutually establish symbiosis with endo-mycorrhizal fungi, however, mycorrhizal associations with almond (prunus amygdalus), particularly in calcareous soils of arid and semi-arid regions, have not been studied. Thus, to realize the symbiotic associatio...

This study performs trend analysis of hydroclimatic varibles and their possible effects on the water resources variability. Nonparametric Mann-Kendall and spearman tests were used to investigate trend analysis of mean annual and 24-hr maximum rainfall, flood and low flow parameters of 23 hydrometery and 18 synoptic stations in Sefid-Roud basin. The results showed that mean annual and 24-hr rain...

Half diallel crosses of nine Iranian wheat cultivars were used to estimate the general and specific combining ability effects and other genetic parameters related to yield and its components. Parents with F2 generations were evaluated at Research Farm, College of Agriculture, University of Shahrekord, in a randomized complete block design with 3 replications. Partitioning of genotypes mean squa...

The above research evaluates the access and use of rural services of the villages in the province of Gilan, as examples of reducing inequalities and increasing the development. The method used in this article is applicable in terms of target, and cross-sectional in tems of identity. To do this research, morris model, indexing method, standardization and dividing by average are used. After compa...

In this study, an inversion method is conducted to determine the focal mechanism of Sefid-Sang fault by comparing interferometric synthetic aperture radar (InSAR) technique and dislocation model of earthquake deformation. To do so, the Sentinel-1A acquisitions covering the fault and its surrounding area are processed to derive the map of line of sight (LOS) displacement over the study area. The...

به منظور بررسی تأثیر محلول­پاشی برگی اسید سالیسیلیک در انگور رقم "بیدانه سفید"(Vitis vinifera cv. Bidaneh Sefid)  تحت تنش ناشی از سمیت بور، آزمایشی به صورت فاکتوریل در قالب طرح بلوک کامل تصادفی در سه تکرار اجراء شد. نهال­های دو ساله انگور رقم «بیدانه سفید» به مدت سه ماه در معرض غلظت­های مختلف بور از منبع اسید بوریک (به صورت کاربرد همراه با محلول غذایی) (2/0(شاهد)، 15 و 30 میلی­گرم در لیتر) و دو...
