Survey of Virtual Water Trade and its Impact on Water Productivity in the Shoshtar MianAb irrigation and Drainage Network

Water is the first and foremost limiting factor for agricultural production, and undoubtedly, water crisis is considered as one of the international challenges for governments and human societies. Given that virtual water was first used as a way to tackle water scarcity in countries with limited water resources, so that countries with low water should import food from abundant countries...

Determining the best irrigation water scheduling with the aim of maximum productivity in irrigation and drainage networks (Case study: Qazvin irrigation network)

In this study, a model was developed to determine the optimal irrigation schedule for the Qazvin Plain in such a way that economic productivity is maximized with the amount of water available and the area under cultivation. The AquaCrop plant growth model was used to determine crop performance in different irrigation programs. The plant growth model was connected to the MATLAB programming envir...

The Effect of Deficit Irrigation, Planting Method and Mulch on the Yield and Water Productivity of Mungbean

In the present study, the effects of different levels of irrigation, organic mulch and planting method on the mungbean yield in Badjgah were investigated. The experimental plan in the first year was full randomized block, while in the second year, it was full randomized split-split plot block design, in three repetitions. The results showed that in the FI treatments, the yield was increased up ...

Impacts of Abattoir Waste-Water Irrigation on Soil Fertility and Productivity

Maximizing Economic Water Productivity Index in Agriculture in Different Levels of Irrigation

Designing an optimal crop pattern and on-time water allocation of water resources along with deficit irrigation are among the optimal solutions to maximize the water economic efficiency index. In this paper, the simultaneous optimization of crop pattern and water allocation are discussed using the deficit irrigation method. The study area is located west of the Qazvin plain irrigation network. ...
