ِdfferent drip (surface and subsurface) and furrow irrigation methods effects on grain, oil and water use efficiency based on grain black cumin(nigella sativa l.) as medicinal plants was investigated. for this purpose, experiment over the past two years (2009 and 2010) in a randomized complete block was designed in three replications. treatments in this research were consisting of 50, 75 and 100...
abstract this study was conducted to determine the impacts of different drip irrigation method and amount of water on yield and water use efficiency of tomato in varamin agricultural research center, iran. the study was done during two years. experimental design was randomized complete blocks design (rcbd) in split plot with three replications. three different drip irrigation method; surface dr...
coriander is one of the important economic plants for medicinal production. this investigation consists of the effects of different drip irrigation (surface and subsurface) and furrow irrigation methods on grain, oil and essential of coriander. for this purpose, experiment over the past two years (2010 and 2011) in a randomized complete block was designed in three replications. treatments were ...
Since the amount of water in the arid and desert regions is limited, the existing water resources utilization methods as well as irrigation methods in these areas are different from other areas. For this purpose, an experiment was conducted as split plot in a completely randomized design with three replications in the Isfahan University of Technology. In this experiment, the amount of irrigatio...
Deficit Irrigation (DI) is a fundamental solution for efficient water use in irrigated lands under conditions of water scarcity. The aim of the present study was to evaluate the potential for water saving and yield improvements of two greenhouse tomato cultivar (Shaqayeq and Shahrzad) with use of three DI treatment ,50, ,75, and ,100, percent of full irrigation along with surface and subsurface...
abstract this study was conducted to determine the impacts of plastic mulch, drip irrigation method and different amount of water and their interactions on yield, water use efficiency (wue) and quality characteristic of tomato (mobile cultivar). the study was conducted in torogh agricultural research station, razavi khorasan province. the study was done during 2007-2008. experimental design was...
Aflatoxins are secondary metabolites produced by Aspergillus flavus, A. parasiticus, A. tamari, A. bombycis and A. nomius species. Relative humidity (RH) is one of the most important parameters influencing the development of aflatoxins in pistachio orchards by Aspergillus species. The type of irrigation system affects density and frequency of the Aspergillus species in the soil. In the current ...
Subsurface drip irrigation systems, compared to other irrigation systems (basin and furrow), enhance the delivery of water and nutrients directly into the root zone. The purposes of this study were to determine wetting front advancement in a subsurface drip irrigation and to compare the results with the HYDRUS 2D model simulation. In this study, the irrigation using T-Tape was carried out on a ...
In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short‐term droughts and yield‐reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomic crops in the region. Microirrigation is typically used for high value fruit and vegetable crops. In recent years and at some locations, microirri...
