Due to the dry climate and limitation of fresh water resources, using fresh and salt water is a solution for crop production under salinity conditions. This study was conducted at Isfahan University of Technology as a randomized complete block design with three replications and five irrigation management treatments in 2014. The treatments included irrigation with saline water (with the salinity...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
hargraves-samani method is one of the methods for calculating plant evapotranspiration that needs minimum meteorological data. in order to evaluate et-hs model in determining sugar beet crop water demand in isfahan, an experiment was conducted at research field of department of agriculture, khorasgan branch, islamic azad university, isfahan, iranin 2005. the study was based a randomized complet...
In order to investigate the effects of furrow irrigation and amount of irrigation water on yield and water use efficiency of corn, an experiment was conducted as a split plot based on a randomized complete block design with three replications for a period of two years at Agriculture Center of Mazandaran. Treatments included three levels of 100, 80 and 60 percent water requirement as the main tr...
In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...
The aim of this study was to evaluate the effect of different levels of soil moisture at irrigation time on root growth, yield and water use efficiency of greenhouse cucumber (Cucumis sativus L.), Yalda cultivar. The experiment was conducted in a randomized complete block design with six treatments and three replications in Isfahan Greenhouse Research Center in 2016. These experimental treatmen...
high groundwater salinity, a high water table and secondary soil salinization are dominant conditions in eastern isfahan province, iran. this region has a low annual rainfall, high annual evaporation demand, saline soils and limited fresh water supplies. to investigate the effects of irrigation deficit and salinity on cantaloupe (cucumis melo l. var. cantalupensis) production, a field experimen...
drip irrigation is the most efficient technique known for improving irrigation water management. a two-year study was conducted to determine the effects of drip and furrow irrigation methods on yield and quality of sugar beet in north of khuzestan. in the first year, the experimental design was a completely randomized block design with three replications. treatments were, three drip irrigation ...
Supplemental irrigation under prolonged drought conditions has a key role in providing water for transpiration of rain-fed fig trees. The effect of different times and amounts of supplemental irrigation at different distances from the tree trunk on quantity and quality of Estahban rain-fed fig production was evaluated during two years. A randomized complete block design with four replications o...
the effects of planting date and single irrigation (si) allocation scenarios on increasing and stability of yield were investigated to determine the total water productivity and economical water productivity (wpe), for rainfed wheat at dryland agricultural research institute in maragheh, iran, during 2000-2004. the treatments included three sowing dates (early, normal and late), four allocation...
