The research aims to study the effects of the climatic elements, rain, dry heat and drought on
wheat and barley production (irrigated and rain-fed) in al-Hasakah station in the Eastern Province,
In order to achieve the objectives of the research a
series of pen'ds of time extending from 2001 to
2010, was adopted Based on the indexes, rates growth and multiple regression the most important
results were as the Following, relation:
1- There is a very strong and statistically significant between the irrigated wheat production
and rainfall, dry heat and drought index, wch was the most influential, effed followed by
precipitation drought index, and by dry heat.
2- There is no statistically significant relationship between rain-Fed wheat production and
rainfall dry heat or drought index.
3- There is a strong and statistically significant relationship between the production of
irrigated barley and rainfall, dry heat and drought index, The most influential effed was drought
index, followed by dry heat, and precipitation.
4- There is no statistically significant relationship between the production of rain-Fed barley
and rainfall and dry heat or drought index.
