introduction fertilizers are the key components which provide plant nutrients' needs in recent years (omid jangir & sing, 1996; kapoor et al., 2007). in many cases, using chemical fertilizers has different negative environmental effects such as soil, water and air pollution, which increase environmental hazardous and production costs (jangir & sing, 1996; kapoor et al., 2007). biological activi...
In order to study the effect of irrigation interval, N fertilization and plant density on yield and yield components of fenugreek, a split-split-plot experiment was conducted in Darmian, Iran in spring 2010. The experiment was conducted in randomized complete block design with three replications. The main plots were subjected to different irrigation intervals of 5 and 10 days. The sub-plots wer...
This experiment was conducted to study the effects of three identified isolates of Arbuscular mycorrhizal fungi (AMF) on growth, acid phosphatase enzyme activity and phenolic compounds (phenol, flavonoid and anthocyanin) of zinnia plants (Zinnia elegans L.var. Magellan Red) under water stress conditions. A factorial (two factors) experiment was planned based on a completely randomized design (C...
Plants are faced with various environmental stresses during their growing period. Each of these stresses have different effects on growth, metabolism and yield according to the sensitivity level and stage of the plant growth. One way of reducing the negative effects of the stresses is to use humic substances. The present study was carried out to evaluate the effects of humic acid and drought st...
سازند کژدمی (اواخر آپتین پیشین – آلبین میانی) یکی از سازند های شیلی مارنی است، که در زون ساختاری زاگرس در جنوب و جنوب غرب ایران قرار گرفته و این سازند بواسطه پتانسیل سنگ منشا بودن مخازن نفت وگاز سازند آسماری در اکثر میادین نفتی، یکی از مهم ترین سازند های زاگرس است. به منظور مطالعات زیست چینه ای و تعیین سن دقیق سازند کژدمی بر اساس فرامینیفرهای پلانکتونیک و تطابق بایوزون های شناسایی شده با بایوزو...
In this study, the effect of deficit irrigation with every–other furrow irrigation method, which is an innovated method in farm irrigation management, was examined on sorghum (Sorghum durra L.) in Bajgah and Kooshkak areas of Fars Province. The experimental design was split plot with three main plots of irrigation interval (10, 15 and 20 days), three subplots of irrigation methods (ordinary fur...

Traditional water-saving irrigation management turns on water pump in a settled interval decided by grower’s experience. The method just saves water on the back of losing yield. In order to result the problem, a kind of greenhouse efficient irrigation management system based on Evapotranspiration has been developed. The system includes greenhouse environmental monitoring subsystem, irrigation a...
let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...
ABSTRACT-Water stress is the main cause for crop yield reduction in the majority of agricultural regions of the world because it affects almost all plant functions. The effects of Glomus mosseae on growth, nutrients uptake, and antioxidant enzymes of sour orange (Citrus aurantium) and rough lemon) Citrus jambheri) rootstocks were assessed in sterilized soil under greenhouse conditions. A three...
