The existence of such a process with limited natural resources needs to improve the optimal and continuous exploitation of available resources. Watershed management is one of the suitable ways to meet nutritional needs and prevent economic consequences. It is impo...
crop’s water use efficiency (wue) is one of the major indices for the efficient use of water for crop production in agriculture. based on scientific literatures, the concept of wue has been defined in all crop management, farm/field, and water basin/irrigation network domains. plant in particular, plays an important role in the efficient use of water and enhancement of wue. plant resistance to ...
the arid zone encompasses land that has an imbalance between precipitation and losses through evaporation. globally, arid zones comprise large part of many countries in the mid-latitudes in both the northern and the southern hemispheres. both australia and iran are countries with a large arid zone. this negative water balance in the arid zone affects the type of land use in these countries. at ...
Exactly estimating of water requirement is essential for water balance studies, design and management of irrigation systems and water resources management. Because of limited soil and water resources in Iran, for optimal use of water resources in the agricultural sector, it is necessary to determine the amount of water requirement by different plants in different climatological conditions. In o...

Plant reproduction is sensitive to water deficits, especially during the early phases when development may cease irreversibly even though the parent remains alive. Grain numbers decrease because of several developmental changes, especially ovary abortion in maize (Zea mays L.) or pollen sterility in small grains. In maize, the water deficits inhibit photosynthesis, and the decrease in photosynt...
Water management by policy makers is based on multi-perspective information. In the case of water, scarcity causes public health, economic, and ecosystem problems because lack safe water when demand exceeds its availability. This study identified influencing components performance systematic review methods two English full-text databases: Scopus ScienceDirect from 2012 to 2022. A total 22 studi...
