RISOverview of Issues in Agricultural Water Management in Iran
The simple productivity equation shows that in order in increase productivity we should decrease water application or increase the yield. A common perception is that irrigation waste tremendous amount of water in Iran. It ...
Determining optimum planting dates for rainfed wheat using theprecipitation uncertainty model and adjusted crop evapotranspiration
Weather variables such as maximum and minimum temperatures and precipitation influence crop pro-duction especially under rainfed conditions. The goal of this study was to determine the optimum plantingdate of rainfed wheat based on crop...
Study of Drought Stress Patterns in Khorasan Province using Climatic-Agricultural Indices
The present study is aimed to evaluate the drought patterns in Khorasan province over the
years of 1983 to 2011. Drought conditions using rainfed wheat yield is an indicator reflecting climate
conditions and patterns, which is used...
Potential impact of climate change on rainfed wheat production in Iran
Potential impact of climate change on rainfed wheat
production in Iran...
The assessment of PERSIANN model as an alternative for interpolation methods toevaluate wheat rainfed yield
Precipitation is the most important factor which affects the rain-fed wheat productivity. Precipitation
characteristics, such as rainfall intensity and duration, usually exhibit significant spatial variation, even within...
Rainfed wheat yields under climate change in northeastern Iran
change on grain yield of rainfed wheat in the Kashafrood basin situated in northeastern Iran. Climate projections of two
General Circulation Models (HadCM3 and CGCM2) under two climate change scenarios (A2 and B2) were employed in
this study. A...
Effect of mycorrhizal symbiosis and supplemental irrigation on yield, grain nutrients and plant residues of chickpea (Cicer arietinum L.)
اثر همزیستی میکوریزا و آبیاری تکمیلی بر عملکرد و عناصر دانه و بقایای گیاهی نخود (Cicer arietinum)
زمان پایان بارندگیهای بهاره در موفقیت زراعت دیم مؤثر است. دو راهکار اساسی (آبیاری تکمیلی و روابط قارچ-ریشه) برای بهبود عملکرد گیاهان زراعی با اثر همافزایی در اعمال توأم آن‌ها وجود دارد. برای بررسی تلقیح میکوریزایی نخود ...
The role of limited irrigation and advanced management on improving water productivity of rainfed wheat at semi-cold region of upper Karkheh River Basin, Iran
and
spring) and Rainfed, and so agronomic management practices consist of two treatments: traditional
and advanced management (TM and AM), were evaluated. The results of this study showed that
under rainfed conditions, wheat grain...
Effects of precipitation and temperature on crop production variability in northeast Iran
Climate variability adversely impacts crop production
and imposes a major constraint on farming
planning, mostly under rainfed conditions, across the world.
Considering the recent advances in climate science, many...
Climate data clustering effects on arid and semi-arid rainfed wheat yield: a comparison of artificial intelligence and K-means approaches
affecting the yield of
rainfed wheat in northeast Iran from 1984 to 2010 (27 years). These variables included sunshine hours, wind speed, relative
humidity, precipitation, maximum temperature, minimum temperature, and the number of wet days...
