Saffron (Crocus sativus L.) is the most strategic and expensive crop in the Islamic Republic of Iran. Shortage and salinity of irrigation water are two major constraints that influence saffron production in arid and semi-arid regions. The objective of the present study is to investigate the...

Model WSM (Wheat Simulation Model) was developed based on the previous model (MSM, Maize Simulation Model). The planted cultivar was Shiraz with five irrigation treatments (1.2, 1.0, 0.8, and 0.5 ratios of the potential irrigation requirement under surface irrigation system and rain-fed) and...

The objective of the present study is to investigate the effects of irrigation water salinity, cow manure levels and different planting methods on saffron growth rate and gas exchange. A split-split plot arrangement was conducted in randomized complete block design with irrigation water salinity...

New strategies of partial root-zone drying (PRD) and deficit irrigations (DI) were studied on potatoes in a semi-arid area of Iran. A factorial experiment was conducted as a complete randomized design in three replications. The potato cultivar treatments were Agria and Ramos. The whole growth...

Optimal crop water allocation has become more challenging in drier areas of the world (short of rainfall) due to increased water scarcity and more frequent droughts. alternative cropping patterns, reallocation of water resources and modification of irrigation are some of the strategies used to...

We investigated the effect of different irrigation and fertilizer regimes on yield of 9-year old pomegranate trees during 2011 and 2012. The experimental design was a split plot as complete randomized blocks with three replications. The main plots contained five irrigation treatments as...

Simulation of crop yield allows better planning and efficient management under different environmental inputs such as water and nitrogen application. However, most of the models are complicated and difficult to understand. Furthermore, input data are not readily available. The objectives of this...

Root distribution of field grown potatoes (cv. Folva) was studied in 4.32 m2 lysimeters and subjected to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. Drip irrigation was applied for all irrigations. Irrigations were run in three different soils: coarse...

Yield and water productivity of potatoes grown in 4.32 m2 lysimeters were measured in coarse sand, loamy sand, and sandy loam and imposed to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. PRD and DI as water-saving irrigation treatments received 65% of FI...

Gas exchange was measured in potatoes (cv. Folva) grown in lysimeters (4.32 m2) in coarse sand, loamy sand, and sandy loam and subjected to full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation strategies. PRD and DI as water-saving irrigation treatments received 65% of FI...
