drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
this study was conducted to assess the effects of irrigation and plant growth promoting bactera on seed yield and qualitative characteristics of black cumin (nigella sativa l.) at the experimental station of the research institute of forest and rangeland, damavan region, iran. a split-plot experimental design, based on randomized complete block design (rcbd) with three replications, was used. i...
Iron (Fe) and zinc (Zn) deficiency is common in wheat growing areas of the world particularly in calcareous soils. Soil application of chemical fertilizers is considered as a cost-effective and easy approach to combat micronutrient deficiency. However, due to economic, environmental, and agronomic constrains, efficiency of soil fertilization is low in most calcareous soils. Therefore, finding p...
چکیده به منظور بررسی اثر تنوع گیاهی و نوع منبع تغذیه ای بر تنوع و تراکم علفهای هرز و حشرات، کارایی مصرف نهاده ها ( نور، آب، عناصر غذایی) و عملکرد و خصوصیات کیفی چند گونه زراعی، آزمایشی به صورت کرتهای خردشده بر پایه طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1385-1384 و 1386-1385 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد به اجرا درآمد. تیمارهای مورد بررسی دو منبع کود دامی و...
the present study was concerned with exploring the frequency and linguistic focus of corrective feedback types given by novice and experienced female teachers working with young learners and compared it with those of elementary classes for adults. moreover, it aimed at measuring learners’ acknowledgement of teachers’ corrective feedback in the form of uptake in relation to linguistic coverage o...
study of agronomic characteristics and advantage indices in intercropping of additive series of chickpea (cicer arietinum l.) and black cumin (nigella sativa l.) abstract in order to evaluate quantitive and qualitive yield of chickpea (cicer arietinum l.) and black cumin (nigella sativa l.) in intercropping of additive series, a field experiment was arranged in a randomized complete block desig...

the main objective of this study was to determine the effects of nitrogen fixing bacteria and manure application on the seed yield and yield components in black cumin (nigella sativa l.). the experiment was carried out at the ran research station in firouzkouh in 2012. a 4×4 factorial experiment, arranged in a randomized complete blocks designed with three replications. the treatments consisted...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
