Abstract
Currently, water scarcity due to severe drought and mismanagement is a prominent challenge in arid regions. The alarming consequences of this phenomenon include water quality deterioration, soil fertility decline, and subsidence, which threaten sustainable development goals. This research aims to present an integrated approach to improving water productivity by using clean household wastewater and technical management of the field in the Sistan region. This study was conducted with treatments of soil texture type (Loamy-clay-silty, loam and sandy-loamy), organic fertilizer (cow and sheep manure), and type of water consumption (uncontaminated household wastewater, Potable water) in a completely randomized design with 12 treatments and three replications. To calculate the water consumption efficiency, was water productivity index (WP) was used. In each treatment, the amount of water consumption was measured during the study period. Growth characteristics of plant, such as height, fresh weight, and Yield (ton/ha) were measured during the growth period of plants too. Based on the results, the volume of water consumed in the treatments was different, and the highest and lowest water consumption was measured to be 245 and 155 liters, respectively. By analyzing the data, the findings showed that the effects of soil texture, fertilizer type at the 1% level, and the interaction effect of soil and fertilizer at the 5% level on irrigation frequency and soil moisture content were significant (p ≤ 0.05). In contrast, the type of water consumption did not show a significant difference.
