Abstract

This study aims to shed light on the relationship between plant disease in wheat crops in Najaf Governorate and climatic conditions. The main driver is the economic and nutritional importance of wheat crops as the main nutrition for the population. The increasing need for this product comes as a result of the increase in the population. This led to the need to work on raising the level of wheat production and improving its quality. But plant epidemics such as diseases in sects and weeds led to fluctuations in their production, especially the sun bug, which was not known before in the region with all its negative effects on wheat crops, which leads to a lack of production and poor quality despite that. The conditions and weather conditions suitable for growing this type of crops in the study area with the possibility of improving these crops, but the average production is not as expected. Therefore, this study aims to clarify the suitability of climatic elements for growing wheat and the relationship of climate and its impact on the spread of the plant epidemic that affects wheat crops which leads to a decrease in production in quality and quantity .


  This study included the theoretical side, including the problem and hypothesis related to the topic, while revealing the study's objectives and justifications. And also dealt with the importance of wheat crops economically and nutritiously, the history of growth and the types that were cultivated in the study area .


The climate of the region is controlled by some fixed and variable systems and their impact on the climatic characteristics of the study region, and the analysis of those characteristics to find out the level of its commodity with wheat crops. It also dealt with the relationship between climatic features and the plant epidemic that affects wheat cultivation (diseases, insects, weeds), in addition to the level of its impact on wheat production and the resulting losses .


1- The suitability of the climatic features represented in the extreme and precise temperatures of the area for the cultivation of wheat with the ability to increase and improve its quality, as it is within the scope of its requirements.


2-The spread of Sunn pest in the study area and its effect on wheat production.


3-The spread of other diseases in plant permits that have a negative impact on the quantity and quality of production.


4- There is some difference in production between regions according to temperature and its effect.
