Wastewaters from leather processing are very complex and lead to water pollution if discharged untreated, especially due to its high organic loading. In this study the survival of different plant species in subsurface horizontal flow constructed wetlands receiving tannery wastewater was investigated. Five pilot units were vegetated with Canna indica, Typha latifolia, Phragmites australis, Steno...
Zareh was primarily received as an introduction wheat within the Winter Wheat Observation Nursery for Irrigated Areas (WWON-IR) with pedigree of 130L1.11//F35.70/Mo73/4/Ymh/Tob//Mcd/3/Lira from CIMMYT-Turkey in 2001-02 cropping season. Zareh was tested as C-83-8 in yield trials under normal irrigation and post-anthesis drought stress conditions in cold regions of Iran. It outyielded Shahryar (n...
katoul is a new soybeam cultivar originated from a genotype named d.p.x.3589 imported from the united states of american in 1990. this genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in gorgan and other research stations during 1999-2002. the mean seed yield of d.p.x.3589 in all these experiments was 3333 kgha-1 ...
Photosynthesis and wheat grain yield responses to supplemental irrigation with different amount of applied water under dryland conditions were investigated. Therefore, a two-year field experiment was conducted research farm of College of Agriculture, Shiraz University during 2004-2005. Five levels of irrigation including dryland conditions, irrigation at stem elongation, booting, flowering an...
بررسی روایت های موجود از مهاجرت نخبگان یا فرار مغزها، موضوع رساله حاضر است. متونی که به مهاجرت نخبگان پرداخته اند هرکدام بسته به راوی و زمینه تاریخی خود روایتی از مهاجرت نخبگان عرضه کرده اند که می توان با رویکردی ساختارگرایانه نسبت به کشف طرح و پیرنگ آنها اقدام نمود. در این راستا تقریبا تمامی کتاب هایی که به این موضوع مربوط می شدند جمع آوری و مطالعه گردید و از میان آنها آثار چهار نویسنده مربوط ...
The use of organic and biological fertilizers is important for achieving sustainable agriculture, reducing the application of chemical fertilizers and the production of healthy crops. A greenhouse experiment was carried out to study the effects of vermicompost, Nitragin, and nitrogen on some growth parameters of strawberry (Fragariaananassa Duch. cv. Aromas). Treatments were arranged in a facto...
Line WB73-6 (Trompillo, CMB74A-432-25B-1Y-IB-1Y-OB) was first introduced in Iran through a nursery received from CIMMYT in 1989. It was selected in a preliminary experiment in Zabol research station among the genotypes of IBON in 1990. In other preliminary and advanced yield trails carried out in Zabol and other stations in southern provinces of Iran with warm climate in 1991-1997, line WB73-6 ...
