Climate elements pose challenges for agriculture. The purpose of this study is to identify agroclimatic risks and their impacts on the growth and development of the vegetative and productive characteristics of two peanut varieties, namely a Sudani or local variety and an improved variety FLEUR 11 for the year observation 2021. The results show that climatic risks condition the development of the characteristics of these varieties through short periods of humidity represented by the ombrothermal diagram and the high frequency of dry sequences, which represent 72.7%, compared to 27.3% for wet sequences. It also appears that species undergo stress due to these risks which results in a difference in their growth and yield. The impacts are also observed in terms of loss of plants and crops.
