The main purpose of this study is investigation of hydraulic properties in drip irrigation tape. In this study, 10 types of drip irrigation tape were tested, and the effect of 4 temperatures of water, 13, 23, 33 and 43 °C, was investigated according to the standard ISO 9261 and ISO IRISI. Initially all experiments were performed in standard temperature (23°C) in order to obtain qualitat...
شایعترین آسیب ورزشی در میان ورزشکاران پیچ خوردگی مچ پا است. بعد از اولین پیچ خوردگی مچ پا درصد بالایی از افراد دچار بی ثباتی عملکردی مچ می شوند. در بی ثباتی عملکردی مچ بدلیل نقص در پروپریوسپشن و افزایش زمان عکس العمل عضلانی، تعادل افراد دچار اختلال می شود. هدف از این مطالعه بررسی تاثیر دو روش مختلف tape بر تعادل استاتیک و دینامیک ورزشکارانی است که دچار بی ثباتی عملکردی مچ هستند. روش کار: درای...
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 order to study the effect of depth of drip placement in soil in subsurface drip irrigation, and fertilization time during irrigation events, on tuber yield of potato, an experiment was carried out in Jiroft area in 1389. This experiment was in a completely randomized block design with four replications, with depth placement of drip tape as the main plot, and fertilization time as the sub-plo...
Delineating the depth and extent of the watermelon [Citrullus lanatus (Thumb.) Matsum. & Nak.] root zone assists with proper irrigation management and minimizes nutrient leaching. The objective of this 3-year field study was to measure root distribution and root length density of watermelon (cv. Wrigley) grafted on two different rootstocks (Lagenaria siceraria cv. ‘FR Strong’ and Cucurbita mosc...
از عوارض پس از بازسازی رباط متقاطع قدامی کاهش حس عمقی و تعادل می باشد. این فاکتورها در وزن اندازی متعادل بر زانوها و راه رفتن نرمال نقش دارند. هدف از این مطالعه مقایسه تأثیرکوتاه مدت و میان مدت taping برحس عمقی، وزن اندازی، راه رفتن و تعادل بیمارانی است که تحت بازسازی رباط متقاطع قدامی قرار گرفته اند. روش کار: دراین پژوهش که به صورت کارآزمایی بالینی تصادفی شده بود 20 مرد ورزشکار با میانگین سن...
in order to investigate the effect of soil matric potential and tube layout on yield and water use efficiency of greenhouse cucumber, a field experiment was carried out during 2010 and 2012 growing seasons at an experimental farm in jiroft territory. the treatments were laid out in strip split plot a randomized complete block design with three replications. the treatments were comprised of fore...
irrigation with saline water needs to the different managements to reduce the harmful effects of salinity on plants, soil and the environment. simulation models are the useful tool to irrigation management in conditions of soil and water salinity because, they can predict crop yield and soil conditions considering to different climate, plant and management practices. in this study, the saltmed ...
Using modern irrigation methods such as border irrigation is one way for an optimum usage of water. Potato, for this study, was cultured in a farm located at Kermanshah faculty of agriculture to evaluate the efficiency of border irrigation. The culture potato was the Agria variety and the applied treatment were 50, 75, and 100 percent of potato plant`s water requirement. Tapes were 12 m and the...
Application of the modern irrigation systems such as T-Tape irrigation system is one of the ways to achieve aptimal irrigation The present study deals with the effect of surface and subsurface drip irrigation systems on the cotton yield For this purpose, a field experiment was conducted in the Agricultural and Natural Resource Research Institute of Orzoueyeh, located in the Kerman province. The...
