introduction: water scarcity is one of the primary problems in arid and semi-arid regions such as iran. in these regions, increasing water productivity in agriculture sector is inevitable. water productivity can be increased using the drip irrigation method and application of irrigation strategies such as deficit irrigation. potato is the major crop in dehgolan plain. researches have shown that...

We simulate the effect of climate change on water requirements of cold seasonwheat in various climatic zones of Iran. The research considers both observedclimate (temperature and precipitation) changes during recent decades (1960-2009)based on instrumental records and projected future changes to 2100 based on theMAGICC/SCENGEN 5.3 compound model. 20 General Circulation models are usedbased on a...

optimum uses of water and nitrogen resources are the most important factors in agricultural systems due to limitations of agricultural inputs especially water. in order to investigate the effect of different levels of nitrogen fertilizer and irrigation on efficiency and productivity of water consumption in three crop (sugar beet, corn and sesame) an experiment was carried out as strip split plo...

abstract in order to study the effects of irrigation regimes on yield and some qualitative characteristics of three cultivars of potato (solanum tuberosum l.), an experiment was conducted in 2009 in the research field of the college of agriculture, ferdowsi university of mashhad. a factorial experiment was arranged in a randomized complete block design with three replications. experimental fact...

Crop water requirement is essential for agricultural water management, which is usually available for crop growing stages. However, crop water requirement values of monthly or weekly scales are more useful for water management. A method was proposed to downscale crop coefficient and water requirement from growing stage to substage scales, which is based on the interpolation of accumulated crop ...

The proposed research work is focused on forecasting the future requirements of water supply based current requirement and also identifying possibility occurrences cracks leaks using ARIMA (autoregressive integrated moving average) model. experiments were conducted real-time experimental hardware. pressure data obtained their p ...
