this study assessed the optimum water need of pepper (capsicum annuum l. cv. california wonder) and the critical irrigation level to be applied in order to achieve a reasonable economic yield in water shortage conditions. in a controlled field experiment involving five different treatments, seasonal evapotranspiration for pepper fluctuated from 89 mm in the severe stress treatment (i0.00) to 1,...
geosmin and mib are the common factors causing odor in the water. water treatment plants usually employ the conventional processes such as aeration, coagulation, flocculation, chlorination or ozonation and adsorption as preventive measures to reduce water odor. but each of these processes alone cannot completely remove the smell. the smell of fish, grass and mud greatly depends on the excessive...
using of saline water for irrigation of crops is known as a strategy of on-farm irrigation water management. in this study, the cyclic using of saline and fresh water and its effect on soil salinity were investigated. field experiments were carried out in randomized complete block design under drip irrigation for maize crop with 9 treatments. the treatments were based on alternative irrigation ...

Background and Objective: Surface water and underground water quality in countries that facing dehydration have increased the interest of the community to use Household Water Treatment devices. The aim of this study was the evaluation of the quality of drinking water of Household Water Treatment devices and general distribution network in Garmsar, which is under the control of the water safety ...
Limited water resource in arid and semi-arid areas is one of the most important problems in the agricultural sector. Therefore, the use of non-conventional water resources becomes more important. For this reason, a study was conducted on barley to evaluate the effect of irrigation with sugar plant wastewater as a factorial randomized complete block design field experiment. Treatments include wa...
population growth as well as global fresh water shortage problem have necessitated the use of unconventional water resources in agricultural sector, as the largest consumer of fresh water, especially in arid and semi-arid regions. in this study, the effect of four irrigation methods on yield, uptake of water and important nutrients, and the salt accumulation in soil was investigated using a com...
the increase in water demand and its services due to population growth and the raising of the standards of living, health, and hygiene along with the limitation of water resources, droughts, and climate change has attracted water specialists and planners to explore the use of unconventional water resources, such as sewage and saline waters. moreover, industrial and rural wastewater disposal and...
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...
