Impact of climatic conditions on yield and plant diseases of winter wheat in North-Eastern Romania

Abstract

Climate elements, such as temperature and atmospheric precipitation, are driving factors in plant diseases developmenet and vary widely between years. Weather factors play a decisive role in achieving higher yields and in the development of plant pathogens. Besides temperature and atmospheric precipitation, wind and relative humidity of the air, play an important role in the development of diseases. In this study are presented the results obtained during the period 2015- 2018, in the northeastern part of Romania, Iasi county. During the three agricultural years studied, the climatic conditions were different from one year to the next. The influence of climatic factors was observed as a result of differences in production yields and the presence of the pathogens and the frequency with which they were manifested. In view of climate change and unfavorable influence on the agricultural sector, cultivation of the most suitable varieties can lead to higher yields, even in years when climatic conditions are unfavorable.
