Location of soil moisture sampling in irrigation management is of special importance due to the spatial variability of soil hydraulic characteristics and the development of root system. The objective of this study was determination of the suitable location for soil moisture sampling in drip-tape irrigation management, which is representative of the average moisture in the soil profile (θavg) as...
The soil salinity and the diffusion of potentially toxic chemicals to the soil environment through industrial and agricultural activities are known as important factors affecting the productivity of crop plants. Thus, an efficient strategy to increase crop yield, and to improve human and environmental health, is necessary to mitigate the impacts of these detrimental factors. Accordingly, a fact...
in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
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...
The present in vivo study was designed to evaluate the efficacy of apical negative pressure irrigation (ANP), passive ultrasonic irrigation (PUI) and positive pressure irrigation (PP) in the reduction of intracanal bacteria of dogs' teeth with pulp necrosis and apical periodontitis. Eighty root canals were randomly distributed into 3 experimental and 2 control groups according to the irrigation...
Water deficit is one of the most important difficulties, in which happes in dry zone and half dry zones.Water deficit, as the determinative factor, determinates the growing and extension of the plant cover inthese areas. Using the supper attractive, may reduce the production in the crops and control the plantcover in face of dry stress and water deficit. In this paper, the effect of supper attr...
Turfgrass évapotranspiration. R. Tovey, J. S. Spencer and D. C. • Muckel. 1969. Agronomy Journal. 61:863-867. (from the University of Nevada, Reno, Ne v. 89507). The lysimeter technique was utilized to measure the rate of évapotranspi ra t ion from two types of turf grown on two different soil textures. The two types of turfgrass were (a) a cool season turf composed primarily of Kentucky bluegr...
writing as a productive skill requires practice in the basic sub-skills of vocabulary and grammar. in fact, grammar has been viewed as the core of programs in writing classes to help the students put the elements of sentence together and combine sentences of specific lengths to come up with an error-free work of art. conceptualizing l2 writing in this way introduces writing as a product and enc...
in order to study the effect of irrigation intervals and intecropped marjoram (origanum vulgare) (as a shading crop for reducing the possible effects of soil warming due to climate change) on the growth and yield of saffron (crocus sativus), a field experiment was conducted as split-plot based on randomized complete block design with three replications, during 2008 and 2009 at the agricultural ...
